Designatronics, Inc., with its divisions and subsidiaries, has been involved since 1960 in the manu-facture and distribution of different mechanical and electronic components.

Advanced Antivibration Components (AAC) is the division of Designatronics devoted to marketingproducts exclusively related to elimination of vibration, energy absorption and protection of componentsand devices from shock and possible destruction.

This is, today, an extremely important field, since instrumentation and recording devices are playingmore and more important roles in our daily lives. These devices are becoming miniaturized and portableand, as a result, are becoming exposed to unexpected hazards.

In addition, different rotating machinery, moving vehicles, machine tools, household appliances, etc.all require vibration control to eliminate undesirable effects that they may cause to their surroundings.

The understanding of the subject of Vibration and Shock requires some amount of theoretical knowl-edge of the theories which govern its causes and subsequent propagation. For this reason, an exten-sive Technical Section, which includes solved problems, is included in this publication.

This handbook contains the broadest offering available from a single source related to antivibrationproducts. In order to facilitate the selection of the proper product, an attempt was made to classify andpresent the products in an especially organized sequence.

Furthermore, since our company is continuously providing services to the Design, Engineering andManufacturing segments for the last 44 years, we are keenly aware of the fact that immediate availabil-ity of components is usually required. Therefore, all items shown in this catalog are available fromstock.

I wish to acknowledge and to congratulate our Engineering staff and our Graphic CommunicationsDepartment for organizing and producing this handbook in such an extensive, attractive and explicitmanner.

Unique Features of This Catalog

1) Our sister division, SDP, started marketing Vibration Mounts in its first catalog published in 1971. It contained only 24 pages of this type of product. Subsequently, in 1978, a special separate volume: Handbook of Vibration Mounts was published. It contained a brief Technical Section, but it reached a 55-product page size. The importance of this product line kept growing and, as a result of it, in 1990 the Vibration and Shock Mount Handbook was published. It contained a 52-page Technical Section and 89 pages of products. More than 15,000 copies were distributed. Subsequently, the Vibration Mount product line became section 8 in the joint SDP/SI inch and metric catalogs.

2) Feedback from our Engineering, as well as Marketing Departments, indicated that for proper marketing of this product line an extensive Technical Section is needed, which was not available in the joint SDP/SI Catalogs. In addition to this, many new product lines related to vibration elimination became available worldwide. These facts gave rise to the publishing of this catalog in order to provide proper support and marketing capabilities, and ADVANCED ANTIVIBRATION COMPONENTS Company was created as a separate Division of Designatronics Inc.

3) In order to provide a revised and broadened Technical Section, we availed ourselves of the services of Eugene Rivin, Professor and Director of the Machine Tool

Laboratory at Wayne State University, Detroit, Michigan. He is a Fellow of the American Society of Mechanical Engineers and of the Society of Manufacturing Engineers, and an Active Member of the International Institution for Production Engineering Research (CIRP). He is the holder of 21 US patents and has authored many books and technical articles, some of which are listed below.

4) Our previous catalogs included only conventionally known vibration elimination components. This catalog also features shock absorbers and shaft couplings capable of elimination of shock and vibration from shaft to shaft.

5) There are catalogs of this type of product circulated; however, the uniqueness of this catalog is its breadth and versatility. In addition to this, all products featured are available from stock for immediate delivery. This feature is extremely important for new designs where prototype testing is an imperative.

6) In addition to the listed stock items, tooling is available for many types and sizes of cylindrical vibration mounts. These are available with metric or inch size studs. In spite of the fact that only small prototype quantities may be required, specially low setup charges will be made for this type of order. For quote requests for these "out of stock " type mounts, please use the numbering system and procedure shown on the next page.

HOW TO CREATE AN INQUIRY

If you don't see the sizes you want in the product section of this catalog, please send us a request for quote using the coding system shown below to specify the size.Please Note: 1) If any inquiry is received for a size combination for which exact tooling is not available, the next closest size will be quoted. 2) D and H dimensions remain metric irrespective of the studs being inch or metric. 3) For metric studs use letter G for thread size and letter L for length whereas for inch size studs, use letter I for thread size and letter N for length.

Selection Procedure for Rubber Mounts

1. Determine the load that each mount will bear when supportingthe equipment weight. Total weight divided by the number ofmounting positions is the load for each mount. This is only truewhen having even weight distribution. Otherwise, distributeweight accordingly.

2. Determine the lowest forcing frequency of the vibration sourceto be supported by the mounts. This is usually equal to the oper-ating speed in revolutions per minute.

3. Choose the percent isolation that will be satisfactory for thepurpose. Except for special cases, 81% isolation is generallyconsidered satisfactory.

4. Referring to the Basic Vibration Chart below, find thestatic deflection for the forcing frequency (Step 2,above) at the chosen percent isolation (Step 3). Notethat a mount must give at least this minimum staticdeflection, with the specific load applied,to providethe desired isolation.

5. Select the mount series with the physical features(shape, attachment facilities,“fail-safe" safety feature,load range, etc.) required by the application.

6. a) Having selected the mount series, refer to the individual styles, and note the styles whose maxi-mum loads are greater than the load each mountis to carry.

b) Referring to the load deflection graphs of the styleslikely to be chosen, locate the applied load value(Step 1, above) on the appropriate graph; i.e.,compression and/or shear.

c) Moving horizontally to the right on the graph, lo-cate the point of intersection with the minimumstatic deflection found in step 4.

d) Mounts with curves above this point of intersec-tion cannot be used, as the load (Step 1) is notsufficient to produce the required minimum de-flection (Step4).

e) Mounts with curves below the point of intersec-tion can be used as, at the given load, the deflec-tion will be greater than the minimum required.Note, however, that if the applied load is abovethe line x--x on a curve, the mount is not recom-mended for this static load.

f) More than one style may have load-deflectioncurvesthat are suitable. The final selection candepend on other requirements such as the costof the mounts, possible in-creased load require-ments in the future, relative advantage of additional isolation, space available for the mounts,

constraints on allowable deflection, attachment re-quirements, etc. However, in the absence of anyoverriding consideration, usually the mount thatis selected has its curve closest to the point ofintersection (Step 6c); i.e., the mount with the minimum de-flection at the applied load.

7. Select the mount that is designed to operate in your tempera-ture range and environment.

compressed 10% up to 30%.

• Low in temperature dependency, this material

offers stable performance from -40°C to 200°C(-40°F to 392°F).

• Excellent chemical resistance.

• Low in compression set.

• Performance stays the same even after

repeated use.

• Contains nothing harmful. Environment-friendly.

RIGHT USE

1. EVEN LOAD

2. HANG IN COMPRESSIVE DIRECTION

INSTALLED SURFACE

WRONG USE

1. UNEVEN LOAD

3. TWIST

4. TENSILE DIRECTION

5. SHEARING DIRECTION

2. BOLT HOLE OUT OF CENTER

FEATURES:

• Compared with circular rubber mounts, these have higher

stiffness in horizontal direction "X" and better stability.They are also well-suited for rotating machines whichgenerate vibrating forces in the horizontal direction.

• Easy to install. The spring rate can be changed just

by altering the mounting positions.

• For the base plate attached type (Fig. 2), a rubber pad is fitted

to the base plate so that the machine can be placed on the floor.

APPLICATIONS

• AIR COMPRESSORS • MACHINE TOOLS

General Characteristics and Uses

Cable Isolators

In Section 5, starting on page 5-23, we offer a large selection of cable isolators.These assemblies are made of aircraft-quality, stranded, stainless steel cable,helically wound into metal retaining bars suitable for surface mounting. Shockand vibration are damped as the result of friction between strands of cableunder load (“flexture hysteresis”). Their superior characteristics include theirability to provide protection in compression, extension, shear and roll in all axessimultaneously.

All stainless steel and aluminum construction gives these units an excellentability to resist corrosion and leads to extremely long maintenance-free life.Below are some of the applications where the cable isolators can be superior toany other type of vibration mounts.

Spring Mounts – Elliptic Leaf Type (Naval " X " Type)

This type of vibration and shock isolator was designed specifi-cally for shipboard or mobile applications. They are particularlysuitable to protect delicate shipboard equipment from shock dueto underwater explosions or sudden stoppage of vehicles forvehicle-mounted equipment.

All materials used are impervious to corrosion and will operateefficiently under a wide range of temperature, making the unitswell-suited for naval or aircraft applications. Their basic designemploys two or more high tensile stainless steel "U" formedleaves, situated at each end, forming an elliptical shape whenjoined together in the center portion with face plates. The spacesbetween the "U" formed leaves are filled with a specially devel-oped polymer or stainless steel mesh.

Nonmetallic collars backed by stainless steel washers aresupplied for load attachment, while providing noise reduction.Inch size or metric bolts may be used for fastening of theequipment to the base or foundation.

Low transmitted shock accelerations are obtained by combin-ing large permitted static deflection in every direction with a highenergy loss within the mount. The high damping efficiency isobtained by the polymer which has a very low static stiffness. Theload-bearing characteristics are determined by the metal con-struction of the mountings. These mounts may be used in tensionas well as compression.

The "X" Mount is one of that rare breed that gives both vibrationisolation and shock protection. Its low frequency ensures effec-tive vibration isolation, except where the resonant frequency ofthe surrounding structure may be sympathetic with the mount'snatural frequency. Similarly, care must be taken during transpor-tation of equipment supported by "X" Mounts.

The main disadvantage of the mount is that transmissibility atresonance is high. In most applications this is not critical as the"X" Mounts are placed in areas that do not coincide with itsresonant frequency. This special applications mount may be ofparticular interest not only for its improved vibration performanceat low temperature, but also its lower natural frequency at roomtemperatures. This may avoid the need of trying to reduce thenatural frequency by means of adding a rubber washer in tandem,as this procedure also increases the transmissibility at resonanceof the system.

Shock protection of the new design has the added benefit ofdurability under repeated shocks at low temperatures.

INSTALLATION OF "X" MOUNTSDue to the sophisticated nature of the "X" Mounts, it is essential

that they be correctly loaded. Incorrect loading will mean inad-equate shock protection (this is true even in underloaded situa-tions).Bad Practice

Due to the shape and size of the "X" Mount, there is a strongtendency to use the space created as storage. Needless to say,

• Heavy Machine Tools

• Air Compressors

• Engine Suspension

• Machine Mounting

• Machine Craft Installations

• Laboratory Equipment

• Electric Motors

• Factory Test Gear

• Seat Suspension in Aircraft andVehicles

• Radar CommunicationsEquipment

• Electronic Control Equipment

• Equipment Mountings in Tanksand Other Military Vehicles

• Bomb and Other Lifting Gear

• Refrigeration Compressors

• Mobile Vehicles

• Fuel Tanks

• Blowers and Fans

• Pumps

any such placement can render the shock protection useless.Preferred Systems

Mounts supporting the system underneath only, with the centerof gravity in the lower third of the unit, is preferred. When this isimpossible, a fully suspended method should be used. Topsteadies can be used where it is difficult to choose mounts tosupport the weight using a fully suspended configuration.

The practice of combining units on one raft is often carried outto ensure that a suitable loading is obtained. This practice isespecially important for operator-controlled equipment; the seatcan be mounted on the raft as well.Orientation

Where possible, the horizontal roll axis should be fore and aft,to minimize equipment movement due to ship roll, but anyorientation is acceptable for shock protection. It is advisable toplace mounts on any one piece of equipment in the samedirection.

V10Z32-1008

INDUSTRIAL AND MARINE APPLICATIONSThe following table gives recommended isolation efficiency in relation to site configuration and driving motor power. If site configuration isnot known, assume for basement condition. Transfer the recommended efficiency to the transmissibility curves on the graph.

EXAMPLEProject a line from the efficiency required on the right -hand side to intersect the performance lines 1008, 1006and 1004. Project those intersections down to obtain thetwo dimensionless ratios (R) for the three mountings.Divide the lowest running speed (Hz) of the completemachine by R to give the natural frequency f 'n required.Compare f 'n with the actual natural frequency (fn) of themounting concerned . If f 'n fits into the fn band of themounting, select that mounting. If two mountings meet theabove conditions, select the one with higher fn; it will bemore stable.

A fan turning at 980 rpm (16.3 Hz) driven by a 7 kw motorrunning at 1470 rpm, which is to be installed on an upperfloor of light construction:

Recommended efficiency = 93%first projection gives R = 5.5 for 1008

and from fn = , fn = = 2.96 Hz

discard 1008 as it has fn = 9 to 7 Hz

second projection gives R = 4 for 1006 & 1004

again fn = = 4.08 Hz

which fits 1004, fn = 5 to 3 Hz

Now, all that remains is to place sufficient 1004series mountings under the machine to supportits weight evenly.

ENERGY ABSORBING PRODUCTS

Within the family of antivibration products, we are introducing a line of ENERGY-ABSORBING PRODUCTS.GENERAL

In order to lend full understanding of the importance and capabilities of this product line, we will deal with the concept of ENERGY as well as present some practicalexamples of several applications. The examples will also include calculations of the forces involved.

Energy-absorbing components are often used as parts of a system or a device itself or, alternatively, they might be used as a safety measure to absorb runaway energy incase of failure of a component or a system. Some numerical examples are addressing both types of these applications.ENERGY

A body is said to possess energy if it has the ability to perform work. This ability can be the result of its position or its condition. The position of the body producesPOTENTIAL ENERGY, whereas if the body is moving with some velocity it possesses energy of motion or KINETIC ENERGY.

The formulas governing energy are as follows:

Kinetic Energy of a body in translation

mV2

where m is mass: m =

V is velocity in in./sec or ft./sec W is weight in lb. g is acceleration of gravity 32.16 ft./sec2 or 386 in./sec2

Kinetic Energy of a body in rotation

E = Io•�2 .....................lb. in. or lb. ft.where Io is the mass moment of inertia about the axis of rotation in lb. in.sec2 or lb. ft.sec2

� is angular velocity in rad/sec or 1/sec

Potential Energy

E = W•h .....................lb. in. or lb. ft.where W is weight in lb. h is height of free fall in in. or ft.

If the velocity at the end of the free fall is needed, it can be found from:

V = 2gh

The total energy is considered the sum total of all energies involved, and this is the amount which is available to perform work.

In the examples which follow, simplified formulas have been developed and used to provide a very close approximation. This enables the application of units which aremost commonly used. The nomenclature used in these examples are as follows:

The actual nature of the application and the availability of space will determine which type of Bumper will be used. In order to facilitate the choice, the following graph is givenwhich compares the Force vs. Travel characteristics of the different types.

These features are obtained by:• Energy absorption: Up to three times as much as conventional shock absorbers. This is achieved by the size of the piston and the large volume of oil.

• Service life: Substantially longer and more reliable as a result of reserve oil storage.

• Damping action: Constant over the entire stroke due to the spiral groove design.

• Cycle time: Minimal due to the large nominal size of the check valve.

• Adjustability: Fast and simple due to the adjustment by means of rotation of the threaded housing.

• Quality: Made to meet the highest requirements: steel, hardened and ground, nickel-plated. Made in Germany.

The damping amount can easily be adjusted within a very narrowrange due to the new and unique design of our shock absorbers.

Adjustment of damping is possible even to the last mm of the stroke.The shock absorber just has to be retracted slightly. By reducing thestroke, you can decrease the braking action.

• Stroke control

Attention! The shock absorber may not be used as a fixed stop.

Finger-Flex Mounts

TYPICAL INSTALLATION ARRANGEMENTS

Any number of Finger-Flex mounts can be installed in parallel to achieve greater load-carrying capacity. These mounts may also be stacked in series to meet greater deflection requirements. Separators between mounts, if used, must be designed to meet the specific requirements of the installation.

Multiple Installations Finger-Flex mounts are used for office machines, electronic equipment, motors, air conditioning equipment, heating equipment, fans, blowers, pumps and scientific equipment.

Typical Installations

Rubber parts used are similiar totype V10R 4-1504 & V10R 4-1505combination. The difference is that theflange of the rubber bushing within thisassembled mounting has fingers ononly one of its surfaces. The ringmember absorbs both vibration andshock.

A.If the load support is1/2 inch (12.7 mm)or more thick, twoFinger-Flex bushings aregenerally used.

B.When the loadsupporting member is1/8 inch (3.18 mm) to1/2 inch (12.7 mm) thick,the standard bushingand ring combination ismost suitable.

C.If the load supportingmember is less than1/8 inch (3.18 mm) thick,the metal surrounding themounting hole should beturned up. This providesadditional mounting areafor the bushing.

Unique Properties of Silicone Gel

Silicone gel has many properties that are superior to many other vibration damping materials such as rubber and urethane.

• Stable performance over wide temperature range: -40°C (-40°F) to 100 ~ 200°C (212 ~ 392°F) depending on the composition.

• Good thermal conductivity.

• Excellent in light-load and high-frequency vibration applications.

• High ozone, UV and chemical resistance.

Many Forms of Silicone Gel Products Are Offered in This Catalog

Shock Absorbent Test

Impact of dropping a fresh egg froma height of 18 m (59 feet) onto a2 cm (.79 in.) thick silicone gel padis gently absorbed without break-ing the egg.

ISO-PAD BOLTINSULATOR

For Bolt Isolation:

Occasionally, machinery must be bolted down because of unbalanced structure, upward pull, safety requirements or local ordinances.Shimming instructions would apply for bolted machinery.

The bolt head should be isolated from the machine base or feet by using a metal washer over a piece of ISO-PAD. The body of the bolt mustalso be isolated. This can be achieved with Bolt Insulator material cut to size, rolled into a cylinder, and slipped over the bolt.

For Machine Leveling:

SHIM increases ISO-PAD height in 3/32 in. (2.4 mm) increments. If metal shims are required, use ISO-PAD SHIM to isolate them from themachine base and eliminate metal-to-metal contact. It is especially useful in assuring level machine installations on unlevel floors.

ISO-PAD SHIM has a composition similiar to ISO-PAD Standard. (See previous page for ISO-PAD Standard)

• Divide for light load. Add for heavy load.

• Make sure of total object load and then select optimum gel pad.

(Example) • For 0.3 kgf (.66 lb.) load, add a board for extra weight or divide V10Z62MSN02 to reduce projections.

• For 10 kgf (22.1 lb.) load, divide V10Z62MSN15 into pieces.

• For 80 kgf (176.4 lb.) load, use two of V10Z62MSN50 and divide if needed.

1.0 FUNDAMENTALS OF VIBRATION AND SHOCK

1.1 What Is Vibration?Mechanical vibration is a form of oscillatory motion. It occurs in all forms of machinery and equipment. It is what you feel

when you put your hand on the hood of a car, the engine of which is running, or on the base of an electric motor when themotor is running. Perhaps the simplest illustration of a mechanical vibration is a vertical spring loaded with weight (W), asshown in Figure 1. In this position, the deflection of the spring from its free state is just sufficient to counterbalance the weightW. This deflection is called the STATIC DEFLECTION of the spring. The position in which the spring is at rest is No. 1. Thespring is then slowly extended to position No. 2 and released. The elastic force moves the block W upward, accelerating upto the mean position and then decelerating moving further up. The uppermost position of the weight (position No. 3) is at thesame distance from position No. 1 as position No. 2, but in the opposite direction. The subsequent motion of the weight as afunction of time, if there is only negligible resistance to the motion, is repetitive and wavy if plotted on a time scale as shownby line 1 in the graph. This simple model exhibits many of the basic characteristics of mechanical vibrations. The maximumdisplacement from the rest or mean position is called the AMPLITUDE of the vibration. The vibratory motion repeats itself atregular intervals (A1, A2, A3). The interval of time within which the motion sequence repeats itself is called a CYCLE orPERIOD. The number of cycles executed in a unit time (for example, during one second or during one minute), is known asthe FREQUENCY. The UNITS OF FREQUENCY are 1 cycle/sec or 1 Hertz (Hz) which is standard. However, "cycles perminute" (cpm) are also used, especially for isolation of objects with rotating components (rotors) which often produce oneexcitation cycle per revolution which can be conveniently measured in cpm. When, as in Figure 1, the spring-weight systemis not driven by an outside source, the vibration is a FREE VIBRATION and the frequency is called the NATURAL FRE-QUENCY of the system, since it is determined only by its parameters (stiffness of the spring and weight of the block).

In general, vibratory motion may or may not be repetitive and its outline as a function of time may be simple or complex.Typical vibrations, which are repetitive and continuous, are those of the base or housing of an electric motor, a householdfan, a vacuum cleaner, and a sewing machine, for example. Vibrations of short duration and variable intensity are frequentlyinitiated by a sudden impulsive (shock) load; for example, rocket upon takeoff, equipment subject to impact and drop tests,a package falling from a height, or bouncing of a freight car. In many machines, the vibration is not part of its regular orintended operation and function, but rather it cannot be avoided. Vibration isolation is one of the ways to control this un-wanted vibration so that its adverse effects are kept within acceptable limits.

1.1.1 DampingThe vibratory motion as a function of time as shown in Figure 1 (line 1) does

not change or fade. The elastic (potential) energy of the spring transforms intomotion (kinetic) energy of the massive block and back into potential energy ofthe spring, and so on. In reality, there are always some losses of the energy(usually, into thermal energy) due to friction, imperfections of the spring mate-rial, etc. As a result, the total energy supporting the vibratory motion in the sys-tem is gradually decreasing (dissipated), thus diminishing the intensity (ampli-tude) of the spring excursions, as shown by line 2 in Figure 1 ("decaying vibra-tion"). This phenomenon is called DAMPING, and energy-dissipating compo-nents are called DAMPERS, Figure 2. The rate of decay of amplitude in a sys-tem with damping is often characterized by LOGARITHMIC (or LOG) DECRE-MENT � defined as

� = log (An/An-1), (1)

Although the cycles of the damped motion as shown by line 2 in Figure 1 are not fullyrepetitive, the number of cycles in a unit of time is still called FREQUENCY.

1.2 What Is Shock?Shock is defined as a TRANSIENT condition whereby kinetic energy is transferred to a system in a period of time which

is short, relative to the natural period of oscillation of the system. Shock usually contains a single impulse of energy of shortduration and large intensity which results in a sudden change in velocity of the system undergoing shock. The principlesinvolved in both vibration and shock isolation are similar. However, differences exist due to the steady-state nature of vibra-tion and the transient nature of shock. Shock may occur in an infinite variety of ways and can be very complex. The simplestform is a single impulse of extremely short duration and large magnitude. Figure 3 [5] shows the most commonly employedpulse shapes used in test specifications.

The reduction in shock severity, which may be obtained by the use of isolators, results from the storage of the shockenergy within the isolators and its subsequent release into a "smoother" vibratory process, over a longer period of time (atthe natural frequency of the spring-mass system) and/or from dissipation of the shock energy (its transformation into thermalenergy). However, the energy storage can only take place by a generally large deflection of the isolator.

Inasmuch as a shock pulse may contain frequency components ranging from very low to very high, it is not possible toavoid excitation of vibratory process of the isolator/mass system with its natural frequency. On the other hand, if the durationof the shock pulse is short, the response of the system may not have serious consequences. Figure 4 [5] demonstrates thecomparative response of a spring mass system to a rectangular pulse whose duration is greater than the natural period of thevibratory system (I) and to a relatively short impulsive-type shock (II).

1.3 What Is Noise?Sound is a vibration of air. The air in this case is an elastic member. The vibrations of the air have a frequency and an

intensity (loudness). The frequency can be expressed in cycles per second or cycles per minute. The audible frequenciesrange from about 20 Hz to about 18,000 Hz, although some human ears are more sensitive and may have a somewhatbroader range. Some sounds are desirable and pleasant for some people, such as music. Unwanted/objectionable soundsrepresent NOISE. Intensity or loudness of noise is measured in decibels (dB). The decibel is a measure of the soundpressure in relation to a standard or reference sound (.0002 microbars, which is the threshold of hearing for sounds for manypeople). The sound/noise loudness in dB is equal to 20 times the common logarithm of this ratio. Typical values of soundpressure level in dB are shown in Tables 1a and 1b.

1.4 Principles of Vibration IsolationIn discussing vibration isolation, it is useful to identify the three basic elements of all vibrating systems: the object to be

isolated (equipment unit, machine, motor, instrument, etc.); the isolation system (resilient isolation mounts or isolators); andthe base (floor, base plate, concrete foundation, etc). The isolators (rubber pads, springs, etc.), are interposed between theobject and the base. They are usually much smaller than the object and the base.

If the object is the source of vibration, the purpose of vibration isolation is to reduce the force transmitted from the objectto the base.

If the base is the source of vibration, the purpose of isolation is to reduce the vibratory motion transmitted from the baseto the object, so that vibratory displacements in the work zone (between the tool and the part in a precision machine tool, themeasuring stylus and the measured part in a coordinate measuring machine, the object and the lens in a microscope, etc.)do not exceed the allowable amounts. That is, probably, the most common case (protecting delicate measuring instrumentsand precision production equipment from floor vibrations, transportation of vibration-sensitive equipment, etc.).

In both cases, the principle of vibration isolation is the same. The isolators are resilient elements. They act as a timedelay and as a source of temporary energy storage, which evens out the force or motion disturbance on one side of thevibration mounts and transmits, if properly selected, a lesser disturbance to the other end (to the base in case of forceisolation, to the object in case of motion isolation).

A judicious design of the vibration isolation system insures that this effect is achieved. Conversely, a poorly designedisolation system, not having proper frequency characteristics, can be worse than no isolation at all.

In addition to its function as a time delay and source of temporary energy storage, vibration mounts can also function asenergy dissipators or absorbers. This effect is usually produced by the damping characteristics of materials, viscous fluids,sliding friction, and dashpots, although in general these may or may not be part of the isolator. The damping, or energy-dissipating effect of an isolator may be negligible or substantial depending on the application. The main purpose of isolatordamping is to reduce or to attenuate the vibrations as rapidly as possible. Damping is particularly important at certainfrequencies which cause RESONANCE. This occurs when the natural frequency of the object on isolators comes close tothe vibration frequency of the source. For example, if an electric motor runs at 3600 rpm, then the object-isolator naturalfrequency of 3600 cycles per minute (60 Hz) corresponds to the resonance condition. If a machine operates near resonance,or has to pass through a resonant speed in order to attain the operating speed, damping is important in alleviation of thevibration buildup.

In summary, a good vibration mount functions as a time delay, temporary energy absorber and to some extent as anenergy dissipator, or damper. The engineering design of a vibration mount consists in identifying the characteristics of thesource of the vibration, the mechanical characteristics of the equipment and the determination of the mount characteristics,in order to achieve a specified degree of vibration reduction.

1.5 Principles of Noise ReductionA good vibration isolation system is reducing vibration transmission through structures and thus, radiation of these

vibration into air, thereby reducing noise.There are many ways to reduce noise. One of the most practical and effective may be the use of vibration mounts. As a

general rule, a well-designed vibration isolator will also help reduce noise. In the case of panel flutter, for example, a well-designed vibration mount could reduce or eliminate the noise. This can be achieved by eliminating the flutter of the panelitself, or by preventing its transmission to ground, or by a combination of the two. The range of audible frequencies is so highthat the natural frequencies of a vibration mount can usually be designed to be well below the noise-producing frequency.

In order to reduce noise, try to identify its sources; e.g., transformer hum, panel flutter, gear tooth engagement, rotorunbalance, etc. Next, identify the noise frequencies. Vibration isolators for these sources designed in accordance with theguidelines for vibration and shock control may then act as barriers either in not conducting the sound, or in attenuating thevibration which is the source of the noise.

2.0 BASIC DEFINITIONS AND CONCEPTS IN VIBRATION AND SHOCK ANALYSIS

2.1 Kinematic CharacteristicsCOORDINATE — A quantity, such as a length or an angle, which defines the position of a moving part. In Figure 1, x is

a coordinate, which defines the position of the weight, W.DISPLACEMENT — A change in position. It is a vector measured relative to a specified position, or frame of reference.

The change in x (Figure 1) measured upward, say, from the bottom position, is a displacement. A displacement can bepositive or negative, depending on the sign convention, translational or rotational. For example, an upward displacementmay be positive, and a downward displacement negative. Similarly, a clockwise rotation may be positive and a counterclock-wise rotation negative. Units: inches, feet, meters (m), millimeters (mm), or, in the case of rotations: degrees, radians, etc.

VELOCITY — The rate of change of displacement. Units: in/sec, mph., m/sec, etc. Velocity is a vector whose magnitudeis the SPEED. Angular velocity might be measured in radians/sec or deg/sec, clockwise or counterclockwise.

ACCELERATION — The rate of change of velocity. Units: in/sec2, m/sec2, etc. It is a vector and has a magnitude anddirection. Angular acceleration might be measured in rad/sec2 or deg/sec2, clockwise or counterclockwise.

VIBRATORY MOTION — An oscillating motion; such as, that of the weight W, in Figure 1.SIMPLE VIBRATORY MOTION — A form of vibratory motion, which as a function of the time is of the form x = a sin �t,

where a and � are constants. The maximum displacement, a, from the mean position (x = 0) is the AMPLITUDE; theFREQUENCY (rate at which the motion repeats itself) is f = �/2� cycles/sec, where ANGULAR FREQUENCY � has thedimensions of rad/sec, and frequency f has the dimensions of reciprocal time; e.g. reciprocal seconds 1/sec. Such motion isalso called harmonic or sinusoidal motion.

PERIOD, CYCLE — The interval of time within which the motion repeats itself. In Figure 5, this is T seconds. The termcycle tends to refer also to the sequence of events within one period.

AMPLITUDE — Figure 5 shows time history of a vibratory motion, which repeats itself every T seconds. The maximumvalues of the displacement, x, from the reference position (x = 0) are called PEAKS. These are (a1, a2...). The largest of theseis called the PEAK AMPLITUDE.

STEADY-STATE MOTION — A periodic motion of a mechanical system; e.g., a continuously swinging pendulum ofconstant amplitude.

STOCHASTIC or RANDOM MOTION — A motion which changes with time in a nonperiodic, possibly very complex,manner.

HARMONICS — Any motion can be considered as made up of a sum (often an infinite number) of simple harmonicmotions of different frequencies and amplitudes. The lowest-frequency component is usually called the FUNDAMENTALFREQUENCY; higher frequency components are called HARMONICS. Their frequencies are multiples of the fundamentalfrequency. Sometimes, components with frequencies which are fractions of the fundamental frequency (subharmonics) aresignificant (e.g., the "half-frequency" whirl of rotating shafts, etc.).

PULSE — Usually a displacement-time or force-time function describing a transient input into a dynamical system.PULSE SHAPE — The shape of the time-displacement or force-displacement curve of a pulse. Typically, this might be a

square wave, a rectangular pulse, or a half sine-wave pulse. In general, however, the shape can be an arbitrary function ofthe time.

SHOCK MOTION — A motion in which there is a sharp, nearly sudden change in velocity; e.g., a hammer blow on a nail,a package falling to the ground from a height, etc. Its mathematical idealization is that of a motion in which the velocitychanges suddenly. This idealization often represents a good approximation to the real dynamic behavior of the system.

2.2 Rigid-Body CharacteristicsMASS — Inertia of the body equal to its weight in lbs. or in Newtons (N) divided by the gravitational constant (g = 32.2 ft/

sec2 = 386 in/sec2 = 9.81 m/sec2). Unit of mass, if the weight is expressed in N, is a kilogram (kg).CENTER OF GRAVITY (CENTER OF MASS, C.G.) — Point of support at which a body would be in balance.MOMENT OF INERTIA — The moment of inertia of a rigid body about a given axis in the body is the sum of the products

of the mass of each volume element and the square of its distance from the axis. Units are in-lb-sec2, or in kg-m2 forexample. Moments of inertia of the standard shapes are tabulated in handbooks. If instead of mass of the element its volumeis used, the result is also called a moment of inertia. Depending on the application, mass-, volume-, or area moments ofinertia can be used.

PRODUCT OF INERTIA — The product of inertia of a rigid body about two intersecting, perpendicular axes in the bodyis the sum of the product of the mass (volumes, areas) of constituent elements and the distances of the element from the twoperpendicular axes. Units are the same as for the moment of inertia. Tabulations are available in handbooks and textbooks.

PRINCIPAL AXES OF INERTIA — At any point of a rigid body, there is a set of mutually perpendicular (orthogonal) axesintersecting in the C.G. such that the products of inertia about these axes vanish. These axes are called the principal axes ofinertia. In a body having axes of symmetry, the principle axes coincide with them. (An axis of symmetry is a line in the body,such that the body can be rotated a fraction of a turn about the line without changing its outline in space).

2.3 Spring and Compliance CharacteristicsTENSION — When a body is stretched from its free configuration, its particles are said to be in tension (e.g., a stretched

bar). The tensile force per unit area is called the tensile stress (Units: lbs/in2 (psi) or Pascals, 1Pa = 1N/m2, 1 Mega Pascal(MPa) = 106 N/m2).

COMPRESSION — When a body is compressed from its free configuration (e.g., a column in axial loading), the com-pressive force unit per area is called the compressive stress (Units: lbs/in2 or Pa).

SHEAR — When a body is subjected to equal and opposite forces, which are not collinear, the forces tend to "shear" thebody; e.g., a rubber pad under parallel forces in the planes of its upper and lower faces. The shear force per unit area iscalled the shear stress (Units: lbs/in2 or Pa). A body can be in a state of tension, compression and shear simultaneously;e.g., a beam in bending.

SPRING CONSTANT — When a helical cylindrical spring is stretched or compressed by x, the displacement x is propor-tional to the applied force, F (Hook's law). The proportionality constant (k) (Units: lbs/in, N/m) is called the SPRING CON-STANT or STIFFNESS, F = kx. If the spring deflects in torsion, the units of k are in-lb/rad, lb/deg, N-m/rad. Such springs arecalled LINEAR SPRINGS. More generally, the load and the displacement are not proportional (a NONLINEAR SPRING). Insuch cases stiffness is changing with the changing load and displacement, and k is the ratio of a force increment ΔF to thecorresponding displacement increment Δx in the loading process. An important issue for spring materials most often used invibration isolators, such as elastomeric (rubber) materials, wiremesh materials, etc., is influence of rate of loading on theirstiffness. The stiffness constant measured at low rate of loading (frequency of load application < ~0.1 Hz) is called STATICSTIFFNESS, kst and the stiffness constant measured at higher frequencies of load application is called DYNAMIC STIFF-NESS, kdyn. The DYNAMIC STIFFNESS COEFFICIENT is defined as Kdyn = kdyn / kst.

FORCE-DEFLECTION CHARACTERISTIC — This refers to the shape of the force-deflection curve. For the linearspring, it is a straight line through the origin of coordinates (constant k). If, for a nonlinear spring, its stiffness increases withincreasing force or displacement (as in many rubber springs loaded in compression), the characteristic is called "hardeningnonlinear". If it decreases with force or displacement (e.g., as in a Belleville spring), the characteristic is called "softeningnonlinear".

ENERGY STORAGE — This is the area under the force-deflection curve of the spring. It represents the strain energystored in the spring (Units: lb. in., lb. ft., N•m).

PRELOAD — A spring or other elastic element used in an isolator or in a coupling may or may not be assembled in acondition in which it has its natural, free, or unstretched length. If its assembled length is not its free length, the spring is intension or compression even before the isolator is loaded by the object weight or the coupling is loaded by the transmittedtorque. The amount of this tension or compression is called the preload. When measured in force units, it is a preload force;when measured in deflection from the free position, it is a preload deflection.

ELASTIC (YOUNG'S) MODULUS (E) AND SHEAR MODULUS (G) — These are material properties, which characterizeresistance of the material to deformation in tension or in compression (E) and in shear (G). They are defined as the ratio ofstress to strain, where strain is the change in length (or deformation) per unit length. E involves tensile or compressive stress/strain and G involves shear stress/strain. Units: lb/in2, Pa. In many practical applications, especially for metals, E and G areconstants within a limit of material stress known as the proportionality limit. Rubber and plastics often do not have a well-defined proportionality limit.

2.4 Damping, Friction and Energy-Dissipation CharacteristicsSTATIC FRICTION, SLIDING FRICTION, COULOMB FRICTION — These are all terms used for the frictional resistance

for sliding of one body relative to another; e.g., a weight dragged along the floor. The frictional force is approximately propor-tional to the contact force between the two bodies and is opposed to the direction of relative motion. The proportionalityconstant f is known as the friction coefficient. If a 10 lb. weight is dragged along a horizontal floor with a friction coefficientf = 0.2, the frictional resistance is 0.2 x 10 = 2 lb. Sometimes a distinction is made between the value of the coefficient offriction when motion is just starting after a stationary condition (STATIC FRICTION) and its value during motion (SLIDING orDYNAMIC FRICTION). The coefficient of friction in the latter case is generally lower and changes with the motion velocity,unless it is DRY or COULOMB FRICTION, wherein the sliding friction coefficient does not depend on velocity. The motion(kinetic) energy is decreasing due to energy dissipation during a sliding process with friction. Thus, frictional connections canbe used as dampers.

VISCOUS DAMPING — If, in a damper, the body moves relative to a second body, VISCOUS DAMPING refers to aresisting (friction) force which is proportional and opposite to the relative velocity between the two bodies. The proportionalityconstant is the coefficient of viscous damping, c. Units: force per unit velocity; i.e., lb/(in/sec) or N/(m/sec). Viscous dampingis encountered, for example, in hydraulic dashpots and devices which squeeze a liquid through an orifice. The more viscousthe fluid, the greater the damping. If c = 0.5 lb/(in/sec) and the body moves at 10 in/sec, the viscous damping force is0.5 x 10 = 5 lb. Typical example: hydraulic door closers.

MATERIAL or HYSTERETIC DAMPING — such as damping in rubber isolators, wire mesh isolators, etc., depends onvibration amplitudes rather than on vibratory velocity. While both viscous and hysteretic damping reduce resonance ampli-tudes, the viscous damping spoils vibration isolation efficiency at high frequencies (when vibration amplitudes are decreas-ing) while the intensity of hysteretic damping automatically decreases with the decreasing amplitudes and it results in abetter isolation efficiency.

CRITICAL DAMPING ccr — Value of damping constant in mass-spring-damping system just sufficiently high so as toprevent vibration.

DAMPING RATIO c/ccr — The ratio of the damping constant to the critical damping constant for that system. Thedamping ratio is related to log decrement � as

� = 2� (c/ccr). (2)

2.5 Vibration Characteristics of Mechanical SystemsMATHEMATICAL MODEL — An idealized representation of the real mechanical system, simplified so that it can be

analyzed. The representation often consists of rigid masses, springs and dampers (dashpots). The model should be suffi-ciently realistic so that results of the analysis of the model correspond reasonably closely to the behavior of the physicalsystem from which it was derived.

LUMPED- AND DISTRIBUTED-PARAMETER SYSTEMS — In a lumped-parameter system, the mass, elastic springand damping properties are separated or lumped into distinct components, each having only mass, only elasticity or onlydamping, but not more than one of these properties per component. In a distributed-parameter system, a component maypossess combined mass, elasticity and damping, distributed continuously through the component. The latter systems repre-sent more realistic models, but are more difficult to analyze.

DEGREES OF FREEDOM — This is the number of independent quantities (dimensions or coordinates), which must beknown in order to be able to draw the mechanical system in any one position, if the fixed dimensions of the system areknown. The simple mass-spring system of Figure 1 has one degree of freedom; a mechanical differential, for example, hastwo degrees of freedom; a rigid body moving freely in space has six degrees of freedom (three translational and threeangular coordinates should be known in order to fully describe the position of the body in space).

FORCE AND MOTION EXCITATION — If a force varying in time is applied to a dynamical system, it usually is a sourceof vibration (e.g., centrifugal force due to an unbalanced rotor). The vibrations are then said to be due to force excitation. If,on the other hand, the foundation (or other part) of a machine is subject to a forced motion (vibration or shock), the resultingmachine vibration is said to be due to motion excitation; e.g., an earthquake actuating a seismograph.

FREE VIBRATION — If the massive block in Figure 1 is moved out of its equilibrium position, and released, the systemwill vibrate without the action of any external forces. Such an oscillation is called a free vibration.

FORCED VIBRATION — If an external force is applied to the weight in Figure 1, which causes it to vibrate (e.g., a forcevarying harmonically with time), the resulting motion of the spring-mass system is called a forced vibration. If the base whichsupports the spring, undergoes a forced motion which in turn causes the weight to vibrate, the vibration is also forced.

RANDOM VIBRATION — Equipment may be caused to vibrate by applied forces or motions in which frequencies andamplitudes of harmonics vary in a random manner with time (e.g., wind gusts on a missile). The resulting vibration is calledrandom.

NATURAL FREQUENCY — Whether the system is without damping or with damping, the frequency of free vibration iscalled the free-undamped natural frequency or the free-damped natural frequency. The natural frequency is a function of themass and stiffness distribution in the system. For a simple-mass spring system, which is a reasonable approximation tomany real mechanical systems, the natural frequency, fn, is

fn = = Hz. (3)

Here, k is spring constant (dynamic stiffness constant kdyn should be used, see Section 2.3); W is the weight; g is thegravitational constant, 386 in/sec2 or 9.8 m/sec2; and xst is the static deflection of the spring. The reciprocal to the naturalfrequency is the NATURAL PERIOD T = 1/fn, sec. If xst is expressed in cm (1 cm = 0.01 m), then the natural frequency canbe conveniently found as

fn � Hz. (4)

The angular natural frequency �n in radians per second is

�n = (5)

Thus, flexible systems tend to have low natural frequencies and rigid systems tend to have high natural frequencies. At thesame time, the natural frequency can be changed by altering the stiffness and mass distribution of the system. A system mayhave more than one natural frequency, in which case the lowest of these is often the most significant one. The number ofnatural frequencies is equal to the number of degrees of freedom of the system. Presense of damping is slightly reducing thenatural frequency; The DAMPED NATURAL FREQUENCY is

fdn = fn 1 – = fn (3a)

where � = 2� (c/ccr)c = damping constantccr = critical damping constant

FORCING FREQUENCY — The frequency of an external force or mo-tion excitation applied to a vibrating system.

2.5.1 Amplitude-Frequency Characteristics of Forced VibrationsIf a sinusoidal force F(t) = Fo sin2�ft is acting on massive block W

connected with the base by spring having stiffness k and viscous damperwith resistance coefficient c, Figure 6, then sinusoidal vibration of blockW is excited. If frequency f is changing but amplitude Fo is constant ina broad frequency range, then amplitude of the vibratory displacementof block W changes with frequency along an AMPLITUDE-FREQUENCYCHARACTERISTIC, Figure 7. Figure 7 shows plots of the displace-ment amplitudes vs. FREQUENCY RATIO f/fn for various degrees of damping (LOG DECREMENT �) in the vibratory sys-tem. The plots in Figure 7 are described by the following expression for the response amplitude A of the massive block W tothe force excitation:

RESONANCE — It is seen in Figure 7that displacement and stress levels tend tobuild up greatly when the forcing frequencycoincides with the natural frequency, the build-up being restrained only by damping. Thiscondition is known as RESONANCE.

In many cases, the forced vibration iscaused by an unbalanced rotating mass, suchas the rotor of an electrical motor. The de-gree of unbalance can be expressed as dis-tance e between the C.G. of the rotor and itsaxis of rotation. The vertical component of thecentrifugal force generated by the unbalancedrotor (mass M) is

Fc.f. = M�2e sin �t = 4�2Mf2 e sin 2�t, (7)

where � is angular speed of rotation in rad/sec and f is the number of revolutions persecond. In case of vibration excitation by theunbalanced rotor, combining of (6) and (7) re-sults in

where m is the total mass of the object. Expression (6a) is plotted in Figure 8 for several values of damping (�).

3.0 Vibration IsolationAlthough VIBRATION ISOLATION is a very large area of vibration control, there are two most widely used techniques of

vibration isolation:

– Reduction of transmission of vibratory or shock forces from the object, in which these forces are generated, to thebase; and

– Reduction of transmission of vibratory motions of the base to the work area of vibration-sensitive objects.

These techniques are similar, but also quite different. They both deal with TRANSMISSIBILITY or TRANSMISSIONRATIO. There are several transmission ratios. Usually these refer to the ratios of the maximum values of the transmittedforce or displacement to the maximum values of the applied force or the forced motion. The important direction of transmis-sion is from the object to the base for the force isolation, or from the base to the object for the motion isolation.

3.1 Vibration Isolation of Vibration-Producing ProductsFigure 9 shows a simplified single-degree-of-freedom model of a vibration isolation

system. While in models in Figure 1 and Figure 2, the base (foundation) is shown ashaving infinite mass, in Figure 9 model the foundation has a finite mass mf. If the forceF(t) = Fo sin2�ft is generated in the object (mass m), the force transmissibility �F from theobject to the foundation is equal to the motion transmissibility �x from the foundation tothe object and is expressed as

This expression (for mf = �) is plotted in Figure 10 which shows that "isolation" of theforce source or the condition of �F < 1 develops at frequencies greater than f = 1.41fn andfast improving with further increasing of the frequency ratio f/fn. The maximum transmis-sibility occurs at the resonance when the frequency ratio f/fn = 1. At resonance (f = fn), thetransmissibility at not very high damping is expressed as

(�F)max = (�x)max � . (9)

While increasing of damping is beneficial at and around the resonance, the isolation at high frequencies deteriorates withincreasing damping �. This effect must be considered in designing the isolation system for a given application. Still, areasonable increase of damping is important since it makes the system more robust if subjected to inevitable spuriousexcitations. Also, the higher damping improves behavior of the system if the object generates forces in a broad frequencyrange; e.g., as unbalanced motor(s) generating continuously changing excitation frequency during its acceleration phase. Itshould be considered that the transmissibility curves in Figure 10 are plotted for viscous damping in the isolators. Dampingin elastomeric and wire-mesh (or cable) elements is different, so-called hysteretic damping. This latter type of damping doesnot affect the preresonance and the resonance behavior of the system, but demonstrate only a minimum deterioration of theisolation at high frequencies even for highly-damped isolators (more in [1]).

Figure 10 Force/Motion Transmissibility in Figure 9 System

Figure 11 Transmissibility of Vibratory Base Motion to Relative Vibratory Motion in the Work Zone

As mentioned before, the goal of vibration isola-tion of vibration-sensitive objects from the base vibra-tion is to reduce relative vibratory displacements inthe work zone. Transmissibility of the base motion intothe relative vibrations θ = x1 – x2 is (for any value ofmf):

�rel = = . (10)

Expression (10) is plotted in Figure 11. It is clear thattransmissibility of low frequency (as compared withthe natural frequency) foundation vibrations into therelative vibrations is very small (since at low frequen-cies the motions are very slow and the object is mov-ing following the vibrating foundation).

ISOLATION EFFICIENCY — Isolation is the per-cent of vibration force that is not transmitted throughthe vibration mounts and which improves with increas-ing frequency ratio. Isolation efficiency of 81.1% cor-responding to a frequency ratio of 2.5, is generallyadequate as shown in Table 2. Figure 12, the basicvibration chart, gives static deflection vs. frequencyand % of vibration isolation (1 - �F). It is useful forselection of vibration isolators/mounts and for calcu-lations (see Section 11).

A more complete treatment of this case of vibra-tion isolation, considering more complex and more re-alistic (several degrees of freedom) models is givenin [1].

3.2 Vibration Isolation of Vibration-Sensitive ObjectsSince, for this group of objects, the relative vibrations in the work zone are determined by dynamic characteristics of the

object itself, a model in Figure 13 should be considered. Floor (foundation) vibration x1 = x10 sin2�ft is transmitted throughvibration isolators (stiffness kv, damping coefficient cv) to frame/bed of the object (mass MB) causing its vibrationsxB = xB0 sin2�ft. The work zone of the object is between the frame/bed and its "upper unit", mass Mu (e.g., tool head of amachine tool or illumination unit of a photo-lithography tool). Stiffness km and damping coefficient cm describe structuraldynamic characteristics of the object, whose structural natural frequency is

fm = . (11)

Accordingly, transmissibility of the vibratory motion of the foundation intothe work zone can be expressed as a product of (transmissibility �x of thefoundation motion X1 to the frame motion from expression (7) where x2 =X1, x1 = XB; and m = MB) and (transmissibility of the frame motion XB tothe relative motion Xrel in the work zone �rel from expression (8) where x2= XB, θ = Xrel, and fn = fm from expression (11)). This operation is illus-trated in Figure 14.

In Figure 14, the plot (a) is maximum intensity ao of floor vibration(displacements amplitudes compounded from numerous on-site measure-ments). It is shown in [1] that for a majority of manufacturing plants ao �2.5�m in the 4-30 Hz range and is much smaller outside of this range forvertical floor vibrations, and ao � 2.0 �m in the 4-20 Hz range and muchsmaller outside of this range for horizontal floor vibrations. For high preci-sion facilities, the levels of allowable floor vibrations are recommended byBBN plots in Figure 15. The next plot (b) in Figure 14 illustrates transmis-sibility from the floor to the object frame for three cases: a - the objectinstalled on rigid mounts (e.g., jack mounts or rigid isolator mounts); b -the object installed on softer, isolating mounts (lower fn) with the samedegree of damping (height of the resonance peak) as the mounts in a; c -the same fn as in b, but greater damping. The third plot (c) illustratestransmissibility from the frame of the object into its work zone; fm is thestructural natural frequency of the object. The bottom plot shows the prod-uct of the previous three plots. An installation is considered successful ifthe vibration amplitude in the work zone does not exceed the allowableamplitude Δo.

It can be seen that a rigid installation results in two peaks of the rela-tive vibration amplitude, which often exceed the tolerance. Both peaksare reduced by using soft isolator mounts: the second one due to reducedtransmissibility at high frequencies per expression (6), and the first onedue to lower sensitivity of the object structure to lower resonance fre-quency of the object on softer isolating mounts. It is clear, that increasingdamping also results in reduced relative vibrations. Accordingly, the re-quirement for an adequate vibration isolation of a vibration-sensitive ob-ject is formulated not as a required upper limit of the natural frequency fn,but as a required upper limit of the "Isolation Criterion" Φ,

Φ = . (12a)

The magnitude of this criterion can be calculated if vibration sensitivity ofthe object in the frequency range of interest is measured and its toleranceis assigned, see [1]. The object is properly isolated if

Φ < , (12b)

where Δo is the maximum tolerated vibratory displacement in the workzone of the object, Xf is the maximum amplitude of floor vibration withfrequency f; �f is the transmissibility into the work zone at frequency f(ratio of relative vibration amplitude in the work zone to amplitude of theobject frame vibration at frequency f). According to this criterion widelyvalidated by practical applications, stiffness of isolators for a given instal-lation can be increased (usually, a very desirable feature) if the isolatorshave higher damping.

Thus, while vibration isolationof the force-producing objectsrequires reducing natural fre-quency in accordance with no-mogram in Figure 12, isolationof a vibration-sensitive objectcan be successful even whensome part of the system is atresonance, provided that thenatural frequency of the isola-tion system and its dampingare properly selected. Vibrationisolation in the latter case isgreatly simplified if structuralstiffness and structural naturalfrequency of the vibration-sen-sitive object are enhanced.

3.3 Shock IsolationThe information in this section has been taken from [2] with

permission of the publisher.It is often necessary to determine the effectiveness of a shock

isolator as well as the magnitude of the acceleration experiencedby elements of the protected equipment. Figure 16, similar toFigure 13, describes the system experiencing a velocity shockas illustrated by the displacement-time curves of Figure 17.

The displacement of equipment (y) supported by isolatorsand subjected to a velocity shock (V) is expressed by the follow-ing equation:

y = V 1 – sin 2�fyt (13)

where fy = is the natural frequency, Hz, of the elasticsystem

consisting of chassis (my) and isolator (ky). Double differentiationof equation (13) yields the acceleration experienced by the equip-ment chassis during shock. This is designated the transmittedacceleration and is expressed as:

y0 = 2�fyV (14)

The units of acceleration y0, are linear distance (inches, m, etc)per second per second. This equation can be expressed anotherway, using more convenient engineering units, as:

Transmitted Shock = = = , (15)

where: V = shock velocity change, in/sec.fy = natural frequency of isolator, Hz.g = maximum acceleration experienced by chassis, ex-

pressed as a dimensionless multiple of the accel-eration due to gravity.

Thus, the maximum acceleration of the chassis during shock, isdirectly proportional to the magnitude of the velocity change andto the natural frequency of the isolator. Figure 18 is a graphicrepresentation of the maximum transmitted acceleration computedfrom Equation (15).

The maximum acceleration expe-rienced by the chassis of the mountedequipment, as indicated in Figure 18,should not be confused with the maxi-mum acceleration experienced by vari-ous elements of the equipment. Thelatter is equal to the product of themaximum chassis acceleration y0 andthe amplification factor A0, which is de-fined as the ratio of the maximum ac-celeration of the element (z0) to themaximum acceleration of the chassis(y0) and is given by:

A0 = (16)

In the absence of damping, A0 is a func-tion only of the element's natural fre-quency (fz) and the isolator's naturalfrequency (fy). For an undamped sys-tem, shock transmissibility (Ts) is re-lated to the amplification factor (A0) asfollows:

Ts = A0 (17)

where shock transmissibility (Ts) is theratio of the maximum acceleration ofthe mass element, mz, to the maximumacceleration of the same elementwhich would occur if the isolator'sspring constant, ky, were infinitely rigid.

Using values for the amplificationfactor A0 as determined in [3], and plot-ted for a range of values of dampingratio, shock transmissibility can be de-termined for a damped system asshown in Figure 19. The damping be-tween mz and my is assumed to beconstant at one percent critical damp-ing (� = 0.063). However, wide varia-tions in the degree of damping havelittle effect on the results. Figure 20gives the amplification factor A0 for thesystem shown in Figure 16 when thesupport experiences velocity shock asillustrated in Figure 17. The factor A0is the ratio of the maximum accelera-tion of mass mz to the maximum ac-celeration of mass my.

Figure 22 illustrates Equation (18). When the damp-ing is small, maximum force transmitted to equipmentis very nearly kdmax.

3.3.2 Sudden Impact on Equipment [3]

Sudden impact, or a sharp blow is characterized by a large force (Fo) acting for a short period of time (to) as shown inFigure 23(a). For practical purposes, suddenness is taken to mean that to is small in comparison with the natural period ofvibration of the system in Figure 23(b). The impulse, I, is defined as the area under the force-time curve; i.e.,

I = Fo to lb-sec or kg m/sec (19)

Application of impulse I results in a sudden downward velocity V of the object,

V = Ig/W. (20)

The maximum isolator deflection and the maximum acceleration of the object can be obtained by substituting V into Equation(18).

4.0 NONLINEARITIESThe equations previously given for transmissibilty (Section 3.1) make certain assumptions which may not always be

valid. For example, it is assumed that the damping is viscous or linear (resistance to relative motion is proportional to therelative velocity). The assumption greatly simplifies the analysis. However, the damping provided by wire mesh is a combina-tion of localized frictional losses by individual wires and hysteresis in the cushion itself. Damping in elastomeric materials hassimilar characteristics. In practical terms, this means that the damping is a function of displacement in addition to velocity,and the terms describing the damping in the equations of motion are nonlinear. At resonance, where the displacement islarge, the damping is high. In the isolation band, where displacement is small, the damping is negligible. This condition givesthe best of both worlds as damping is only desirable under resonance conditions. Thus, the idealized curves in Figure 10 areon the conservative side since they show deterioration of isolation in the high frequency (after resonance) range.

A second assumption is that the flexible members or mounts behave as linear springs. This again is not strictly true asmany mounts behave as hardening springs to a lesser or greater extent, depending on material of their flexible elements(e.g., proportion of mesh cushion in the wire-mesh mounts) and/or on design features of rubber flexible elements. As theterm suggests, the stiffness increases with load/displacement. This property has the useful effect of increasing the dynamicload-carrying capability of the mounts. Consider the Equation (3) for the natural frequency of a simple spring-mass system.As can be seen, increasing the weight load (mass) of the isolated object reduces the natural frequency. But if the stiffness isincreasing as well (as in the case of a hardening spring) then the ratio k/m is less dependent on the mass of the object andthe mount can be used in a wider load range. Some vibration isolators are designed with their stiffness proportional to theweight load,

k = AW = Amg, (21)

where A is a proportionality constant. For such mounts the natural frequency is

fn = = = Ag = const. (22)

Accordingly, such vibration isolators are called CONSTANT NATURAL FREQUENCY (or CNF) ISOLATORS. This meansthat a mount will give the same degree of isolation for a broad load range, with the ratio of upper load limit and lower load limitup to and exceeding 20:1 [1]. An example of a CNF isolator is Ring Mount V10Z47M in this catalog.

Besides the convenience of using the same isolators for widely different objects, CNF isolators have many other advan-tages. The tolerance on stiffness of constant stiffness (linear) isolators with rubber flexible elements is usually about ±17%.Such wide tolerance leads to a need for greater safety factors in order to achieve the required degree of isolation, and thusto softer isolators. The soft isolators are undesirable since they may result in a shaky installation. CNF isolators, on the otherhand, are very robust and variation of rubber hardness due to production tolerances do not influence the natural frequencysignificantly [1]. Other advantages of CNF isolators are addressed below in Section 6.0.

The other way in which a stiffening spring affects the dy-namic performance of a system is to make the natural frequency"input sensitive". As the amplitude increases, so does the dis-placement. Consequently, that stiffness increases as well. Thenatural frequency (fn) increases also. Figure 24 [5] shows acomparison between the way frequency fn changes with ampli-tude for a linear spring (a) and a hardening spring (b). As canbe seen, with a hardening spring, fn increases with amplitude.Without going into the mathematical treatment, it should beappreciated that the actual responses for various inputs will beas shown in Figure 25 [5]. It can be seen that the resonant pointactually changes with different inputs. A softening spring is addedfor comparison.

Another property of mesh mounts is demonstrated by Figure 26 [5]. As can be seen, in practice there is a sudden sharpdrop from the resonant point, ensuring that isolation is achieved almost immediately. However, it is again safer to assumethat isolation does not begin until 2 fn is achieved.

Figure 27 demonstrates that there are six independent ways in which a body can move; i.e., it has SIX DEGREES OFFREEDOM. The reader must be aware from this that there is a potential of six independent natural frequencies, as well aspossible coupled modes of vibration.

Figure 29 Setup for Experimental Finding of the C.G. Location

The coupling concept can be illustrated on the example of a simpler "pla-nar" system shown in Figure 28, which shows a mass supported by springs andconstrained so that it can move only in the plane of the drawing [5]. Such asystem has three coordinates which fully describe its configuration: translationalcoordinates x and y, and angular coordinate . If the system is symmetricalabout axis y, then when excited by a sinusoidal force Fy, in the vertical directionalong the axis of symmetry, the object will behave as previously shown (Figure1), namely by vibrating in the vertical (y) direction. However, if the force vectordoes not coincide with the axis of symmetry, then the vertical force would excitevibratory motions not only in the y-direction, but also in x and directions. Whenthe mass is excited by a horizontal force Fx, both horizontal (y) or longitudinalmode and pitching () vibratory motions are excited. These modes are said tobe coupled when vibrations of one mode can be stimulated by a vibratory forceor displacement in another. Coupling modes are in most cases undesirable. Forexample, many vibration-sensitive objects have the highest vibration sensitivityin a horizontal direction, while the floor vibrations are often more intense in thevertical direction. Coupling between the vertical and horizontal directions canbe avoided by using vibration isolating mounts at each mounting point whosestiffness is proportional to the weight load acting on this mount (CNF mount) [1].

6.0 STATIC LOAD DISTRIBUTION CALCULATIONIn order to calculate the weight distribution between the mounting points, the position of the CENTER OF GRAVITY

(C.G.) has to be determined first. It is a simple task only for an axisymmetrical object. Position of the C.G. can be obtained bycomputation or experiment. The computational approach is feasible in most cases to the manufacturer who has all relevantdrawings containing the data on mass distribution inside the object. The experiment is suggested by the definition of the C.G.as the point of support at which the body will be in equilibrium. For example, a small object can be supported on a peg; whenin equilibrium, a vertical line drawn through the peg will pass through the C.G. Unfortunately, this method is applicable onlyto small objects. For large objects, such as machine tools, the object is mounted, for the C.G. location purposes, onto threeload cells LC1, LC2, LC3, as shown is the plane view in Figure 29. If the weight loads as sensed by these load cells are W1,W2, W3, respectively, then coordinates of the C.G. are as follows:

xC.G. = ;

(23)

yC.G. = .

After the C.G. position is known, weight distribution between themounting points should be calculated. Such a calculation can berigorously performed only for the case of an object with three mount-ing points (a statically-determinate problem). Unfortunately, only arelatively small percentage of objects requiring vibration isolationare designed with the "three point" mounting arrangement. If thenumber of the mounting points is greater than three, the accuracyof weight distribution calculations is suffering, unless the mountingsurface of the floor is flat and horizontal and the mounting surfaceof the object is also flat. The tolerance on the "flatness" requirementshould be a small fraction of the projected static deformations xst ofthe selected vibration isolators.

For example, if the vertical natural frequency of the isolatedobject is fn = 20 Hz, then, from Equation (4), xst = 0.0625 cm or0.625 mm.

Similarly, for fn = 10 Hz, xst = 2.5 mm, andfor fn = 5 Hz, xst = 10 mm.

Hz. When the machine is installed on five linear isolators with rubber flexible elements selected in accordance with themanufacturer's recommendations, different for different mounting points (line 2, fn = 15 Hz), the maximum amplitude of therelative vibrations (resulting in waviness of the ground surface) was 0.35 �m. However, when the grinder was installed onfive indentical CNF isolators with rubber flexible elements (line 1, fn = 20 Hz, or about two times stiffer than the linearisolators), the maximum relative vibration amplitudes was 0.25 �m, about 30% lower.

7.0 CONNECTIONS OF SPRING ELEMENTS

7.1 Springs in ParallelThese combine like electrical resistance in series. This is the case when several springs

support a single load, as shown in Figure 34. The springs are equivalent to a single spring,the spring constant of which is equal to the sum of the spring constants of the constituentsprings. The spring constant k of the single equivalent spring is given by:

k = k1 + k1 + k1. (27)

7.2 Springs in SeriesThe series connected springs in Figure 35 combine like electrical resistances in parallel.

The equivalent single spring is softer than any of the component springs. The spring con-stant k of the equivalent single spring is given by:

= + . (28)

If n springs are in series, this formula is readily extended to:

= + + + ..... + . (29)

7.3 Spring Connected Partly in Parallel and Partly in SeriesObtain equivalent spring constants for each set of parallel or series springs separately

and then combine. For example, in Figure 36, the springs k1 and k2 are equivalent to a singlespring, the spring constant of which, ke1, is given by:

= + = or ke1 = (30a)

The three springs, k3, k4, k5 in parallel, are equivalent to a single spring, the spring constantof which, ke2, is given by:

ke2 = k3 + k4 + k5 (30b)

Now equivalent springs ke1 and ke2 are in series. Hence, the spring constant k of the equiva-lent spring for the entire system is:

= + or k = (30c)

8.0 3-D OBJECT DRIVEN BY VIBRATORY FORCE AND TORQUES

Figure 37 shows an object with its C.G. at C, mounted on 4 flexible mounts and acted upon by a disturbing harmonicforce Fy in the y-direction (vertical) and/or by torques, Tx, Ty and Tz acting singly or in combination about the x, y and z axes,which are principal inertia axes passing through the C.G. (point C).

The four mounts are symmetrically disposed relative to the C.G., their location defined by distances bx, by and bz fromthe axes, as shown. The mass moments of inertia about the principal inertia axes are Ix, Iy and Iz, respectively. As a result ofthe external force and torques, the object motion is (a) a displacement of C.G., maximum values of which are denoted bytranslational motions of the C.G. (x, y, z) and (b) rotations of the object (from equilibrium) about the coordinate axes (θx, θy,θz). These displacements are generally small relative to the major dimensions of the object.

Let: M = mass of object (W/g where W is weight of the object, g = 386 in/sec2 = 9.8 m/sec2);ky = total vertical stiffness of the four supports in lb./in. or N/m; i.e., 4 times the stiffness of each support

if all four supports are identicalks = total horizontal or shear stiffness of the four supports; i.e., 4 times the horizontal stiffness of each

support, if all supports are identical and for each support kx = kz = ks, lb./in. or N/m;� = angular frequency of sinusoidally applied force and torques (rad/sec)

Damping is assumed to be negligible.

8.3 Mount DeflectionsIf the object motions in all coordinates are as expressed in 8.1 (x, y, z, θx, θy, θz,) and if the coordinates of the mounting

point (vibration isolators) are (X, Y, Z) in the equilibrium position, then their deflections (ΔX, ΔY, ΔZ) from equilibrium due tothe applied force/torques are:

ΔX = x – θzY + θyZΔY = y – θxZ + θzX (45)ΔZ = z – θyX + θxY

provided the deflections are small relative to the object dimensions.However, if the effects of more than one disturbing force/torque are to be combined, the corresponding deflections of

each mount must be combined vectorially, not be added algebraically, as in Equation (45).

General Comments1. It is desirable to make sure that the disturbing forces and torques operate at frequencies sufficiently far removed

from the computed natural frequencies, so that resonance conditions are avoided.2. The compliance of the vibration mounts in compression and shear should be such that their combined compliance

yields natural frequencies which are sufficiently lower than the frequencies of the disturbing forces and torques (hopefully at least by a factor of 2.5).

3. The displacements (max. deflections) of the mounts can be calculated from Equation (45) for any given singledisturbing force or torque. If several force/torques act simultaneously, vector addition of forces in different directionsis required, and Equation (45) cannot be used.

4. The case of a horizontal disturbing force has not been considered in this presentation.5. Other things being equal, the best arrangement for the mounts is to arrange them so that their resultant force

passes through the center of gravity of the equipment and that its line of action is a principal axis. If there is aresultant torque about the center of gravity, its direction should be about a principal axis through the center ofgravity. However, if this arrangement is impractical, it need not be adhered to.

9.0 COMPLEX DRIVING FORCES

When the disturbing forces are neither sinusoidal nor suddenly applied, the vibration analysis becomes more compli-cated. While it is more difficult to give general guidelines or methods of analysis, one can consider every force-time variationas composed of components of different frequencies, each being a multiple of the basic (usually driving) frequency. Math-ematically, this is known as expanding an arbitrary function into a Fourier series. Once these frequency components (har-monics) are determined, each one being sinusoidal at a different frequency, any component can be analyzed like a sinusoi-dal force. This can provide at least some understanding of the vibration phenomenon. Often the lowest-frequency (funda-mental) component predominates and is the most important component to analyze. It is possible, however, that the design ofthe vibration isolation system will appear unfeasible on the basis of an analysis of only the fundamental component, whereasthe exact analysis would show that a vibration isolation mounting can be useful; i.e., sometimes an analysis of componentsof several frequencies may be required [1]. This, however, may be quite difficult. In such cases, resolving an arbitrary force-time variation into several harmonics can provide some insight.

The following represents data in the Fourier series (decomposition into several harmonics) of some representative force-time variations in Figure 38, which are neither sinusoidal nor sudden. Each force is assumed to be a periodic function of thetime;

λ = τ/T, where τ is pulse width, T is the process period;� = fundamental frequency.

The Fourier expansions for these forcing functions are given in Table 2.

where A2, A4, A6 are given as follows in Table 3 [4].

Problem No. 1A metal tumbling unit weighing 200 lbs and driven by a 950 rpm motor is to be mounted for at least 81% vibration

isolation effieciency from the tumbling drum and motor unbalance (one cycle per revolution, or 950 cpm) using 4 cylindricalmounts in shear. Select the isolators.

The weight load per mounting is (1/4) x 200 lbs = 50 lbs. From the basic vibration chart, Figure 12, a forcing frequency of950 cpm (~ 16Hz) and 81% isolation lead to a point of intersection corresponding to a static deflection of 0.25 in.

Cylindrical mount Part Number V10Z 2-311C, loaded in shear, has a deflection 0.32 in. at 50 lbs. Since this deflection isin excess of 0.25 in., the isolation will be greater than the design minimum. From the basic chart in Figure 12, it is seen to bebetween 85-90%.

Problem No. 2Consider the tumbling unit of Problem No. 1 and suppose the motor speed were increased to 2500 rpm. What isolators

could be used, allowing loading both in shear and in compression?From the basic vibration chart, Figure 12, for a forcing frequency of 2500 cpm and 81% isolation, we find a static

deflection of about 0.037 in. Hence we must look for isolators with a load rating not less than 50 lbs and with a correspondingdeflection of not less than 0.037 in. The following mounts can be considered:

Load in Compression Load in ShearV10Z 2-300C (0.078 in. deflection) V10Z 2-330B (0.14 in. deflection)V10Z 2-317C (0.078 in.) V10Z 2-311C (0.31 in.)V10Z 2-310B (0.138 in.)V10Z 2-314C (0.042 in.)

Amongst these, the highest percentage of isolation is afforded by the mount with the largest deflection (V10Z 2-311C),provided that such a deflection is permissible.

Problem No. 3A small business machine is to be mounted for 81% vibration isolation effieciency. The weight is 25 lbs and there are 4

mounting points. What additional information is required for the selection of the vibration isolation system?Information which is needed is as follows: allowable vibration amplitudes of the machine, as a function of frequency;

frequency of disturbing force; direction and point of application of disturbing force; space limitations, if any; ambient condi-tions, if unusual; mass and compliance distribution of machine – if not uniform.

Problem No. 4A device contains 4 symmetrically located special-configuration isolators (Finger-Flex), Part Number V10R 4-1502D,

each isolator deflecting just over 0.07 in. at 20 lb load. In order to obtain satisfactory vibration isolation, it is desired toincrease the deflection from 0.07 in. to 0.14 in., the load remaining the same. How can this be done?

One way is to stack two (identical) mounts in series, see section 7.2, each of the four isolators being replaced by such aset.

Problem No. 5A unit which is to be mounted for 81% vibration isolation efficiency has a forcing frequency of 1500 cpm (25 Hz), weighs

1080 lbs and is to use 6 vibration isolators in shear. Isolators with a female tap are required. Select an isolator model.The load per isolator is 1080/6 = 180 lbs. At 1500 cpm and 81% isolation effieciency, the basic vibration chart, Figure 12,

gives a static deflection of 0.10 in.Isolator V10Z 2-308C loaded in shear has a deflection of about 0.13 in. at 180 lbs. This being in excess of 0.10 in., the

degree of isolation is certainly satisfactory. This model has a female tap.

Problem No. 6A 275 lb motor is mounted with cylindrical isolators V10Z 2-311C loaded in shear at six points, the forcing frequency

being 1100 cpm (~ 18 Hz). What is the percentage of vibration isolation attained?The load per isolator = 275/6 = 45.8 lbs, assuming mounts to be symmetrically located, so that load is evenly distributed.

From the design information furnished in the catalog, the shear deflection of the isolator at this load is ~ 0.28 in.From Figure 12, the point of intersection of 0.28 in. static deflection and forcing frequency of 1100 cpm gives an isolation

efficiency of about 87%.

Problem No. 7An air conditioner weighs 250 lbs and is driven by a motor at 1700 rpm. The unit is mounted in shear on four V10Z 2-

317B cylindrical isolators. Is this design satisfactory?

The isolated unit is not properly installed because the maximum load rating for this isolator, as indicated in the catalog,is 21 lbs in shear and 40 lbs in compression. The load per mount is 250/4 = 62.5 lbs. Even if the isolator is installed so thatit is loaded in compression, it would not be satisfactory, since the load (62.5 lbs) is significantly in excess of the 40 lbsrecommended limit.

Mounts, which have sufficient load capacity, are as follows (with static deflection indicated):

Part Number Static DeflectionV10Z 2-310B (Compression) (0.175 in.)V10Z 2-311C (Shear – marginal) (0.38 in.)V10Z 2-330B (Shear) (0.175 in.)

The choice of isolators depends (amongst other matters) on the degree of isolation desired. With any of the aboveisolators, this will be in excess of 81% for the forcing frequency equal to motor rpm.

Problem No. 8If, in the preceding problem, the air conditioner weighs 350 lbs, what is the choice of mounts?The load/mount is 350/4 = 87.5 lbs. The following mounts can be considered (with static deflection indicated):

Part Number Static DeflectionV10Z 2-314C (Compression) (0.075 in.)V10Z 2-311D (Compression) (0.094 in.)V10Z 2-330B (Shear) (0.26 in.)

At 1750 cpm, 81% vibration isolation corresponds to a static deflection of 0.074 in.

Problem No. 9A computer weighs 200 lbs. It is to be vibration isolated with 4 mounts. The forcing frequency is 1750 cpm (~ 29 Hz). If

the isolators are to be loaded in compression, what models are available and what is the percentage of vibration isolationattained in each case?

The load per mount is 200/4 = 50 lbs. Hence, isolators with a load capacity of at least 50 lbs in compression are needed.For each isolator, the catalog contains data (table or plots) from which static deflection under a 50 lb load can be found. Fromthe basic vibration chart, Figure 12, with this value of static deflection and a forcing frequency of 1750 cpm, the point ofintersection defines the attained vibration isolation efficiency. Thus, the following isolators can be selected:

Problem No. 10A 4-cylinder engine weighing 370 lbs and operating at 2800 rpm is to be isolated for 81% vibration isolation for one-per-

revolution excitation frequency. Discuss the possible selection of isolators.The lowest frequency to be isolated is 2800 cpm (~ 46.5 Hz). In general, it is desirable to arrange the mounts so that the

resultant of the loads, supported by the mounts, passes through the C.G. This is the same condition (but stated differently) asthe one described in Section 5.0 above. If the isolators are symmetrically arranged, and each isolator carries the same load,this usually means that the symmetry axis of the isolators passes through the C.G. In this case, we are concerned not onlywith the translational displacement of the engine as a whole, but also with engine rotation. In addition, flexible gas lines andthe throttle linkage can vibrate and their vibration isolation may pose an additional problem.

At 2800 cpm and 81% isolation efficiency, the basic vibration chart, Figure 12, gives a static deflection of about 0.03 in.The load is 370/4 = 92.5 lbs per mount.

Consider rectangular mount V10Z 6-500B loaded in shear. This has a deflection of about 0.12 in. in shear, which canaccommodate the rotation of the engine about the torque-roll axis. The mount deflection in compression would serve toaccommodate the shock load in translation.

Problem No. 11An 80 lb fan is to be vibration isolated in shear at four points with at least 93% vibration isolation efficiency when the fan

is turning at 2000 rpm. Specify the mounts.The main source of vibration is rotor unbalance, and the transmission to ground of the vertical component of this force,

(which is sinusoidal) is undesirable (see [1] for isolation of other vibration components). Hence, consider Section 3.1, Equa-tion (8), with negligible damping.

Solution #1:From the basic vibration chart, Figure 12, 93% isolation at a forced frequency of 2000 cycles/minute (~ 33.3 Hz) corre-

sponds to a static deflection of about 0.14 in. and to a natural frequency of about 500 cpm (~ 8.5 Hz).Consider cylindrical vibration isolators, Part Number V10Z 2-300C loaded in shear, which deflects about 0.17 in. at 20

lbs and appears to be suitable for this application.

Solution #2: (Analytical)When the isolation efficiency is 93%, the force transmissibility, �F is 1 – 0.93 = 0.07 or 7%. With zero damping (δ = 0),Equation (8) gives for δ = 0:

�F = (48)

where �F = 0.07;"+" is to be used when f < fn, and"–" is to be used when f > fn.

Since for good isolation, f > fn, "–" sign will be used.

Solving for f/fn from Equation (48), we obtain f/fn = 3.91.Since f = 33.3 Hz, fn = 8.52 Hz.From Equation (4), solving for xst = 0.344 cm = 0.136 in.

These calculations agree adequately with the values found from the chart in Figure 12.

Problem No. 12Data as in problem 11, but damping is estimated at c/ccr = 0.1, see Section 2.4 above. How would it change the specifi-

cations?The force transmissibility, �F, corresponding to 93% vibration isolation efficiency, is 0.07 and the forcing frequency is

2000 cpm (33.3 Hz). From Figure 10, for damping ratio c/ccr = 0.1 at � = 0.07, the frequency f/fn = ~ 5.Hence, fn = 2000/5 = 400 cpm (~ 6.7 Hz).From the basic chart, Figure 12, this natural frequency corresponds to a static deflection of ~ 0.21 in. Since the load

remains at 20 lbs per mount, the isolators specified for Problem 11 are too stiff. Isolator V10Z 2-310B loaded in shearappears to be satisfactory (deflection ~ 0.33 in. at 20 lbs).

This problem could also have been solved by a computer program, or analytically. In the latter case, Equation (8) can besolved for fn at the value c/ccr = 0.1, f = 33.3 Hz.

Comparison of Problems 11 and 12 shows that viscous damping in isolators results in increasing transmissibility at theisolation frequency range (which starts from f/fn = 2 = 1.41); i.e., reducing effectiveness of isolation and requiring softerisolators to get the desired efficiency. This is the price to pay for very desirable reduction of resonance amplitudes. When thedamping is not viscous but material damping, such as in isolators with rubber flexible elements, the deterioration of the highfrequency isolation is minimal.

Problem No. 13 A Vibroactive Object (Machine)A small machine tool weighs between 3.5 lbs and 5 lbs depending on the weight of the work piece. When the forcing

frequency, which is generated by the vibration source inside the machine, is between 60-90 Hz. and again when it is within200-400 Hz range, the vibration is objectionable. Design a vibration mount for a 3-point support with vibration isolationefficiency of not less than 81%.

In the absence of more information, we may assume that isolators have zero damping. If we isolate for the lowestobjectionable forced frequency (60 Hz), that would take care of all the troublesome regions.

From the basic vibration chart, Figure 12, an 81% isolation ratio at a forced frequency of 60 Hz corresponds to a staticdeflection of about 0.019 in. The weight supported by each mounting ranges from 3.5/3 lbs to 5/3 lbs, or from 1.17 to 1.67 lbs.The natural frequency is read off from the chart at about 23 Hz. Hence, the vibration mount specification is:

0.019 in. deflection1.17 lbs to 1.67 lbs supported weight.

Square mount V10Z 1-321B loaded in compression is a possibility. Considering the special configuration (Finger-Flex)mounts, Part Number V10R 4-1500A can be selected. Its deflection at 1.17 lbs is only about 0.03 in. In view of its construc-tion, the spring rate of this mount increases rapidly with deflection and the special configuration unit would be both moreeconomical in the use of space and more effective in taking care of overloads, if this should arise.

Problem No. 14 A Vibration/Shock Sensitive ObjectSensitive radio equipment is to be mounted with a 3-point suspension on a boat. Protection from engine disturbance is

required, as well as from impacts of waves and from bumping against pier. The equipment weighs 54 lbs and the engine runsat 2000 rpm.

Here we have both steady vibrations at 2000 cycles/min as well as shock loads, caused by wave pounding and bybumping against the dock. We have no precise information on the latter and need to do the best we can.

For the steady vibration, consider Equation (8) with zero damping which becomes Equation (48). At 81% efficiency andforcing frequency of 2000 cycles/min, the basic vibration chart, Figure 12, gives a static deflection of about 0.058 in. The loadper mount is 54/3 = 18 lbs. The natural frequency obtained from the chart is about 760 cycles/min = 12.7 Hz.

V10R 4-1504B ring-style special-configuration (Finger-Flex) mount approximately fulfills this condition.In order to limit the effect of shock loads, conical bumpers may be added to limit the horizontal shock load, possibly with

the V10Z 7-1020C type.It can, however, also be made an arbitrary guess and assumption that the pier and waves effects are equivalent approxi-

mately to a 0.5 mph sudden change of horizontal velocity of the boat and try to design the vibration mount for this condition.This will provide some insight into how much of a sudden velocity can be expected to be cushioned by vibration mounting.This corresponds to Section 3.3.1 of horizontal motion and negligible damping (c/ccr = 0).

It is also important to know how much force the sensitive radio equipment can take without damage. Often such a forceis expressed as a g-load; i.e., how many times its own weight the equipment can survive. For example, a 1/2 g-load meansthat the object can withstand a maximum force of (1/2) (54) = 27 lbs without damage. Usually, the allowable shock loads aredetermined by testing. Let's assume that the maximum safe load on the radio equipment is 1g or 54 lbs.

From Equation (15), Section 3.3.1, we have

= = 1,

where V = 0.5 mph = 8.8 in/sec = 0.22 m/sec. Hence, f = 7 Hz.This frequency is quite low, and associated with undesirably large deflections of vibration isolators. This suggests using

a cylindrical mount loaded in compression for the vertical (engine) vibrations and having reasonably large compliance in thehorizontal (shear) mode to take care of some of the shock, with a conical bumper to limit excessive horizontal deflections.

For example, cylindrical mount V10Z 2-300A has 0.075 in. deflection at 20 lbs compressive load, while in shear, thedeflection at 16 lbs is about 0.32 in., or six times as much. This is an overload, but might still be considered due to theinfrequent occurences of the shock load.

The natural frequency in the shear mode based on the 16 lb load is about 5.7 Hz, which is 20% lower than the 7 Hzspecified above.

From Equation (18), = = 1, thus dmax = 0.32 in. Note that dmax is computed as if the weight were supportedin shear.

This is too large a maximum deflection. A conical bumper should be used to limit the deflection by 0.20 in., say. Alterna-tively, a stronger and stiffer mount should be considered, for example, V10Z 2-300B, which deflects 0.26 in. at 18 lbs inshear. The isolation effectiveness in compression is reduced to about 65%; and while the isolation ratio in shear is alsoreduced, so is the corresponding maximum deflection. In addition, the conical bumpers should be added. The final choice ofmounts is a matter of judgment.

Problem No. 15A single-cylinder gasoline engine drives a one-cylinder air compressor with belt. Both units are bolted to a light-gage

metal pan, which is welded to the top of an air-receiver tank, which is in turn mounted to a four-wheel steel-tired dolly. Thewhole unit vibrates and walks all over the floor. The engine weighs 100 lbs and turns at 3000 rpm. The compressor weighs120 lbs and turns at 1200 rpm. The tank weighs 25 lbs and the dolly weighs 50 lbs. What can be done?

Possibly good rubber tires on the dolly and/or wheel suspension would help. If the tank is mounted to the dolly, totalweight is:

W = 100 + 120 + 75 = 295 lbs.

The lowest-frequency disturbing force is that due to the air compressor; i.e., 1200 cycles/min = 20 Hz. At 81% vibrationisolation efficiency, Figure 12 gives a static deflection of the isolator of about 0.15 in. Considering a 4-mount suspension, theload per mount is 74 lbs.

Cylindrical mount V10Z 2-310B would be a possibility, loaded in compression. If the dolly continues to move, since itweighs only 50 lbs, it might require a little softer material than the 40-durometer rubber, in order to effect more isolation.

Next, consider mounting on isolators the pan that holds the engine and air-compressor unit. The total weight here is 100+ 220 lbs and with the same static deflection of 0.15 in., a V10Z 2-310A mount would suffice in compression, considering thefact that the chart shows the V10Z 2-310B mounts to deflect 0.12 in. at 55 lbs. The lower-durometer mount (Type A, at 30-durometer) should, therefore, approximate the 0.15 in. required deflection. Note that the last letter in the mount identificationspecifies the approximate durometer hardness of the rubber (A = 30, B = 40, C = 50).

Problem No. 16 Isolation of a Punch Press (also see [1]).This is one of the most difficult applications for isolation. Shock absorption is all that can be expected. Unit weighs 1500

lbs, sits on four feet, operates at 50-100 rpm, and is driven by a 5 H.P., 1750 rpm electric motor, the flywheel turning at 250rpm.

While many vibration problems deal with sinusoidal or nearly sinusoidal forces and some (such as in package cushion-ing) deal with essentially sudden velocity changes, here we have a suddenly applied force, which is periodic, but not har-monic. The force-time variation is essentially that of the "Repeated Step" in Section 9.0.

If we assume that the punching operation of the press occurs, say, during 30° of crank rotation, then the λ in this case(Repeated Step, Section 9.0) is 30/360 = 1/12 = 0.08333. From Section 9.0, we find that the amplitude of the fundamentalharmonic is (2/π) sin πλ or 0.164. This is only about 16% of the amplitude of the force pulse, and its frequency is operatingfrequency (50-100 rpm or 0.85 - 1.7 Hz).

Consider, however, the 4th harmonic (200-400 cycles/min). Its amplitude is (2 sin 4πλ)/4π = .1376 or 13.8%. This is notmuch less than the amplitude of the basic (fundamental) frequency. This shows that in the punch-press type of disturbingforce, the higher harmonics cannot be neglected.

The fundamental frequency (50-100 cycles/min) is so low that isolation with vibration isolation mounts would lead to theirexcessive static deflections. However, it is conceivable that a practical vibration isolator would be successful in isolatingsome of the significant higher harmonics. For vibration isolation of punch presses, the following few rules might be useful(also see [1]).

1. Slow-speed presses should be mounted with mounts of greater deflection than high-speed presses.2. Mount deflections used for presses by direct installation of vibration isolation mounts under their feet may vary

from 1/32 in. to 3/4 in. depending largely on operating speed and stroke length, with the smaller deflection beingthe more common.

3. There may be several static deflections that will work, while other static deflections interspaced in between themwill not work; i.e., 1/16 in. and 3/16 in. may work, while 1/8 in. may not work. This can be caused, at least in part,by the fact that a significant set of higher harmonics may be isolated at one deflection, but not at another.

4. Even the best mounting system will still transmit a significant amount of vibration and shock.5. If the ultimate in isolation is required, the punch press must be attached solidly to an inertia block of large mass

and the entire press and the block mounted on vibration isolators.

Problem No. 17A relatively high-precision experiment is to be conducted in the laboratory of a textile plant. The laboratory floor vibrates

at an amplitude of 0.0005 in. due to the operation of industrial sewing machines and other textile machinery. The basic floor-vibration frequencies are that excited by the industrial sewing machines, which operate in the 1500-5000 rpm range. It isdesired to vibration isolate the test unit, which weighs 25 lbs, with a four-point mounting at not less than 81% isolation ofdisplacement.

At 81% displacement isolation, the displacement transmissibility, �x is 0.19. It is calculated using the same equations (8)and (48) as for �F.

For zero damping, Equation (48) gives:

�F =f2___f2n

Taking f as the lowest sewing-machine speed (1500 cycles/min or 25 Hz) and �F = 0.19, we find fn = 600 cycles/min = 10 Hz.The static deflection of the vibration isolators is determined from Equation (4), as xst = 0.25 cm = 0.1 in. The same result canbe obtained from Figure 12. The isolation specification, therefore, is 0.10 in. static deflection at a load of 25/4 = 6.25 lbs.

Considering cylindrical vibration isolators, mount V10Z 2-316B loaded in shear, has a 0.10 in. deflection at about 6.25lbs. Soft mounts, such as this one, are often using shear deformation of the flexible elements.

Problem No. 18Data as in Problem 17, except that system damping is estimated at 10% of critical (� = ~ 0.63). Reevaluate the specifi-

cation of the isolators.In Problem 17, we found that the displacement transmissibility corresponding to 81% isolation is �x = 0.19; and that the

lowest forcing frequency, f = 1500 cycles/min. = 10 Hz. From Figure 10, p.T1-11, which applies to �x as well as to �F, we findthat the given value of the transmissibility at � = ~ 0.63 yields a frequency ratio f/fn = ~ 2.7. Hence, fn = 1500/2.7 = ~ 9 Hz.

At this natural frequency, the basic vibration chart (Figure 12) gives a static deflection of about 0.117 in. The load permount, as in Problem 17, is 6.25 lbs.

The isolator specification V10Z 2-316B of Problem 17 remains satisfactory.

Problem No. 19An impact testing machine consists of a simple pendulum of length 4 feet and weight 5 lbs, which is initially horizontal. It

is released and at the bottom of its swing impacts the test object. In this test, it comes to rest essentially instantaneously(inelastic impact). The object (equipment to be tested) weighs 100 lbs and is capable of withstanding accelerations up to 2g.Design a vibration isolation/mounting system so that the equipment will survive the impact test.

The velocity aquired by the pendulum in the 4 foot drop is

Vo = 2gh, = 193 in/sec (striking velocity), where g = 386 in/sec2; h = 4 ft. x 12 = 48 in.

The momentum of the pendulum just prior to impact is equal to the impulse "I" applied to the object. It is equal to the mass ofthe pendulum times its velocity,

I = x 193, or 2.5 lb-sec.

If the pendulum retains a residual velocity Vp' just after striking the test object, "I" would be computed from

I = (Vp – Vp') x (mass of pendulum).

The impact result is an essentially sudden velocity change by V1, of the equipment, which, can be calculated from Equation(20) as:

V = in/sec.

= in./sec. = 9.65 in./sec.

This value of V can be used in Equation (15), or

= =

with amax = 2g and V = 9.65 in./sec. Then fn = g/�V = 1.35 Hz.

Realization of such low natural frequency (albeit, in a horizontal direction; less destabalizing than in the vertical direction)is a very special problem. It can be addressed by utilizing information in [1].

The minima on these plots rep-resent structural natural frequencies of the devices. At each fre-quency f, transmissibility from the base to the work zone is �f =Δo/Xb.

Since the vibration sensitivity �f of this precision object isknown (can be easily calculated from the experimentally obtainedplots in Figure 40) then Expression (12b) can be used for speci-fying vibration isolation parameters.

The values of ΦBv and ΦBh were calculated using floor vibration levels corresponding to line VC-B in Figure 15 (both forvertical and horizontal directions). Since plots in Figure 15 are given for vibratory velocity Vf, vibration displacement ampli-tudes Xf were calculated for each frequency of interest as Xf = Vf/2�f.

Values of ΦA calculated per Specification A are interesting only for comparison, since high precision microelectronicproduction equipment is never used in conventional plant facilities, only in specially designed buildings complying with someof VC criteria.

It can be seen from Table 4A that the lowest value of ΦAv (case A) for vertical direction is 4.51 Hz. If vibration isolatorswith medium damping �ν = 0.6 are used, then from Equation (12a) the required vertical natural frequency fv = 4.51 0.6 =3.04 Hz. However, if isolators made of rubber with high damping �ν = 1.2 are used, then fv = 4.51 1.2 = 5.0 Hz, which canbe realized by passive isolators with soft rubber flexible elements.

Much stiffer isolators (fvz > 14 Hz) can be used to comply with values of ΦBv, per Specification B, which represent(according to not very stringent requirement VC-B) floor conditions at the microelectronics industry installations.

A similar situation is seen in Table 4B; however, realization of natural frequencies corresponding to ΦBh (4.7 Hz for �ν =0.6, 6.63 Hz for �ν = 1.2) in horizontal directions with elastomeric isolators does not present any difficulty; even much lowervalues can be easily realized.

The logarithmic decrement given here represents the negative of the power to which 10 must be raised in order to obtainthe ratio of any two consecutive amplitudes (on the same side of zero deflection) as unexcited vibration dies out. Forinstance, if the logarithmic decrement is 0.2, the ratio of one amplitude to the preceding one is

10-0.2 = = = 0.631 = successive amplitude ratio.

(Ordinarily, logarithmic decrement is referred to natural logarithm base e, and if such values are required, they would be2.30 times the values given here.)

Figure 1 Relationship Between Horsepower, Torque and Rotational Speed

1.0 INTRODUCTION

A coupling is a design component intended to connect shafts of two mechanical units, such as an electric motor and ahydraulic pump or compressor driven by this motor, etc. As stated in the Resolution of the First International Conference onFlexible Couplings [1, 3], "...a flexible coupling, although it is relatively small and cheap compared to the machines it con-nects, is a critical aspect of any shaft system and a good deal of attention must be paid to its choice at the design stage." Thefollowing is a brief engineering data on couplings. More details are available in [1, 3].

The application considerations for couplings are numerous. The most important are the following:

• Torque and Horsepower• Allowable Shaft Misalignment• Lateral and Axial Flexibility of Coupling• Torsional Flexibility• Backlash• Rotational Velocity Error• Service Conditions

2.0 APPLICATION CONSIDERATIONS

Flexible couplings are designed to accommodate various types of load conditions. No one type of coupling can providethe universal solution to all coupling problems; hence many designs are available, each possessing construction features toaccommodate one or more types of application requirements. Successful coupling selection requires a clear understandingof application conditions. The major factors governing coupling selection are discussed below.

2.1 Torque and HorsepowerThe strength of a coupling is defined as its ability to transmit a required

torque load, frequently in combination with other factors.Hence, a coupling may be selected whose rated torque capacity is many

times greater than needed. For example, in a coupling subject to wear andincreasing backlash, a useful torque rating would depend chiefly on back-lash limitations rather than strength. For manually operated drives, the torqueimposed through improper handling may be in excess of the drive torquerequired. Couplings are frequently specified in horsepower capacity at vari-ous speeds.

Horsepower is a function of torque and speed, and it can be readily de-termined from the formula:

HP =

where N = rotational speed in rpm and T= torque in lb. in. This relation-ship is graphically represented in Figure 1.

2.2 Shaft MisalignmentShaft misalignment can be due to unavoidable tolerance build-ups in a

mechanism or intentionally produced to fulfill a specific function. Various typesof misalignment, as they are defined in AGMA Standard 510.02, are shownin Figure 2.

2.3 Lateral and Axial Flexibility of CouplingsLateral and axial flexibility of couplings are factors frequently overlooked. The term flexible does not mean that the

coupling gives complete freedom of relative movement between the coupled shafts. More properly, flexible couplings give alimited freedom of the relative movement. Some forces are needed to make a flexible coupling flex. These forces are eitherlateral (at right angles to the shafts), or axial, or a combination of both. Lateral forces may produce a bending moment on theshafts and a radial load on the shaft support bearings. Axial force can produce undesirable thrust loads if not considered inthe original design. Universal Cardan joints and Oldham couplings impose friction-generated lateral loads on the bearings.The elastomeric types of couplings will produce lateral forces in proportion to their stiffness. These issues are addressedbelow in Section 3.0.

2.4 Torsional FlexibilityTorsional flexibility of a coupling is the torsional (twisting) elastic deformation induced in a flexible coupling while trans-

mitting torque. In some applications using encoders, it may be essential that the torsional flexibility be very low so as not tointroduce reading errors caused by the angular displacements. On the other hand, torsional deflection may be desirable forreducing torque oscillations and peak torques in driving high inertia and/or dynamic loads.

2.5 BacklashBacklash is the amount of rotational play inherent in flexible couplings which utilize moving parts. In some applications,

this "slack" may not be objectionable, but in an application in servo-controlled systems, such as described in the previousparagraph, backlash would rule out couplings of this type.

2.6 Rotational Velocity ErrorIn addition to the types of error already described, universal joints produce an error because of their kinematic behavior.

If the input speed into a single universal joint is held constant, then the output will produce cyclic fluctuations in direct relationto the operating angles of the input and output shafts. This will be described more fully in the section dealing with UniversalJoints.

2.7 Service ConditionsService conditions encompass factors such as temperature, operating medium, lubrication, accessibility for mainte-

nance, etc., and should be reviewed before a final selection is made.

3.0 GENERAL CLASSIFICATION OF COUPLINGS AND THEIR PERFORMANCE CHARACTERISTICS

Couplings play various roles in machine transmissions. According to their role in transmissions, couplings can be dividedinto four classes:

1. Rigid Couplings. These couplings are used for rigid connection of precisely aligned shafts. Besides torque, they alsotransmit bending moment and shear force if any misalignment is present, as well as axial force. The three latter factors maycause substantial extra loading of the shaft bearings. The principal areas of application: long shafting; very tight spacepreventing use of misalignment-compensating or torsionally flexible couplings; inadequate durability and/or reliability ofother types of couplings.

2. Misalignment-Compensating Couplings. Such couplings are required for connecting two members of a power-trans-mission or motion-transmission system that are not perfectly aligned. "Misalignment" means that components that are co-axial by design are not actually coaxial, due either to assembly errors or to deformations of subunits and/or their foundations,Figure 2. The latter factor is of substantial importance for transmission systems on nonrigid foundations.

If the misaligned shafts are rigidly connected, this leads to elastic deformations of the shafts, and thus to dynamic loadson bearings, vibrations, increased friction losses in power transmission systems, and unwanted friction forces in motiontransmission, especially in control systems.

Misalignment-compensating couplings are used to reduce the effects of imperfect alignment by allowing nonrestricted orpartially restricted motion between the connected shaft ends. Similar coupling designs are sometimes used to changebending natural frequencies/modes of long shafts.

When only misalignment compensation is required, rigidity in torsional direction is usually a positive factor, otherwise thedynamic characteristics of the transmission system might be distorted. To achieve high torsional rigidity together with highmobility/compliance in misalignment directions (radial or parallel offset, axial, angular), torsional and misalignment-compen-sating displacements in the coupling have to be separated by using an intermediate compensating member. Frequently,torsionally rigid "misalignment-compensating" couplings, such as gear couplings, are referred to in the trade literature as"flexible" couplings.

3. Torsionally Flexible Couplings. Such couplings are used to change the dynamic characteristics of a transmissionsystem, such as natural frequency, damping and character/degree of nonlinearity. The change is desirable or necessarywhen severe torsional vibrations are likely to develop in the transmission system, leading to dynamic overloads in power-transmission systems.

Torsionally flexible couplings usually demonstrate high torsional compliance to enhance their influence on transmissiondynamics.

4. Combination Purpose Couplings are required to possess both compensating ability and torsional flexibility. The major-ity of the commercially available connecting couplings belong to this group.

3.1 Rigid CouplingsTypical rigid couplings are shown in Figure 3. Usually, such a coupling comprises a sleeve fitting snugly on the con-

nected shafts and positively connected with each shaft by pins, Figure 3a, or by keys, Figure 3b. Sometimes two sleeves areused, each positively attached to one of the shafts and connected between themselves using flanges, Figure 3c. Yet anotherpopular embodiment is the design in Figure 3d wherein the sleeve is split longitudinally and "cradles" the connected shafts.

3.2 Misalignment-Compensating CouplingsMisalignment-compensating couplings have to reduce forces caused by an

imperfect alignment of connected rotating members (shafts). Since componentswhich are designed to transmit higher payloads can usually tolerate higher mis-alignment-caused loads, a ratio between the load generated in the basic mis-alignment direction (radial or angular) to the payload (rated torque or tangentialforce) seems to be a natural design criterion for purely misalignment-compen-sating couplings.

All known designs of misalignment-compensating (torsionally rigid) cou-plings are characterized by the presence of an intermediate (floating) memberlocated between the hubs attached to the shafts being connected. The floatingmember has mobility relative to both hubs. The compensating member can besolid or composed of several links. There are two basic design subclasses:

(2a) Couplings in which the displacements between the hubs and the com-pensating member have a frictional character (examples: Oldham coupling, Fig-ure 4; universal Cardan Joint, Figure 5; gear coupling, Figure 6.)

(2b) Couplings in which the displacements are due to elastic deformationsin special elastic connectors (e.g., "K" Type Flexible Coupling, Figure 7).

3.2.1 Selection Criterion for Frictional Misalignment-CompensatingCouplings

For Subclass (2a) couplings designed for compensating the offset misalign-ment, the radial force Fcom acting from one hub to another and caused by mis-alignment, is a friction force equal to the product of friction coefficient ƒ andtangential force Ft at an effective radius Ref, Ft = T/Ref, where T is transmittedtorque,

Fcom = ƒFt = (1)

Since motions between the hubs and the compensating member are of a "stick-slip" character, with very short displacements alternating with stoppages andreversals, ƒ might be assumed to be the static friction coefficient.

When the rated torque Tr is transmitted, then the selection criterion is

= (2)

or the ratio representing the selection criterion does not depend on the amountof misalignment; lower friction and/or larger effective radius would lead to lowerforces on bearings of the connected shafts.

Similar conclusion stands for couplings compensating angular misalignments(Cardan joints or universal, or simply, U-joints). While U-joints with rolling fric-tion (usually, needle) bearings have low friction coefficient, ƒ for U-joints withsliding friction can be significant if the lubrication system is not properly de-signed and maintained.

3.2.1a Oldham CouplingsOldham couplings consist of three members. A floating member is trapped

by 90° displaced grooves between the two outer members which connect to thedrive shafts, as shown in Figure 4.

Oldham couplings can accommodate lateral shaft misalignments up to 10%of nominal shaft diameters and up to 3° angular misalignments.

Lubrication is a problem but can, in most applications, be overcome by choosing a coupling that uses a wear-resistantplastic in place of steel or bronze floating members.

Some advantages of Oldham couplings:• High torsional stiffness;• No velocity variation as with universal joints;• Substantial lateral misalignments possible;• High torque capacity for a given size;• Ease of disassembly.

Shortcomings of Oldham couplings:• Limited angular misalignment of shafts;• Need for lubrication due to relative sliding motion with stoppages, unless wear-resistant plastic is employed;• Nylon coupling has reduced torque capacity;• Significant backlash due to initial clearances for thermal expansion and inevitable wear;• Are not suitable for small misalignments;• Suitable only for relatively slow-speed transmissions;• Possible loss of loose members during disassembly.

Oldham couplings with rubber-metal laminated bearings [1] have all the advantages of the generic Oldham couplingswithout their shortcomings.

3.2.1b Universal or U-joints [2]

3.2.1b.1 GeneralA universal joint, Figure 5, is a positive, mechanical connection between rotating shafts, which are not parallel, but

intersecting. It is used to transmit motion, power, or both. It is also called the Cardan joint or Hooke joint. It consists of twoyokes, one on each shaft, connected by a cross-shaped intermediate member called the spider having four trunnions provid-ing for rotatable connections with the yokes. The angle between the two shafts is called the operating angle. It is generally,but not always, constant during operation. Good design practice calls for low operating angles, often less than 25°, depend-ing on the application. Independent of this guideline, mechanical interference in the U-joint designs often limits the operatingangle to a maximum (usually about 37.5°), depending on its proportions.

Typical applications of U-joints include aircraft, appliances, control mechanisms, electronics, instrumentation, medicaland optical devices, ordnance, radio, sewing machines, textile machinery and tool drives.

U-joints are available with steel or plastic major components. Steel U-joints have maximum load-carrying capacity for agiven size. U-joints with plastic body members are used in light industrial applications in which their self-lubricating feature,light weight, negligible backlash, corrosion resistance and capability for high-speed operation are significant advantages.

Recently developed U-joint designs with rubber-metal laminated bearings [1, 3] have even higher torque capacity and/orsmaller sizes allowing for higher-speed operation, and can be preloaded without increasing friction losses, thus completelyeliminating backlash. These designs do not require lubrication and sealing against contamination.

Constant velocity or ball-jointed universals are also available. These are used for high-speed operation and for carryinglarge torques. They are available in both miniature and standard sizes.

Motion transmitted through a U-joint becomes nonuniform. The angular velocity ratio between input and output shaftsvaries cyclically (two cycles per one revolution of the input shaft). This fluctuation, creating angular accelerations and in-creasing with the increasing angular misalignment, can be as much as ±15% at 30° misalignment. Effects of such fluctua-tions on static torque, inertia torque, and overall system performance should be kept in mind during the transmission design.

This nonuniformity can be eliminated (canceled) by using two connected in series and appropriately phased U-joints,Figure 8. While the output velocity becomes uniform, angular velocity fluctuation of the intermediate shaft cannot be avoided.

Two U-joints in series can be used for coupling two laterally displaced (misaligned) shafts, while the single joint can onlyconnect the angularly-misaligned shafts.

Advantages of a single U-joint:• Low side thrust on bearings;• Large angular misalignments are possible;• High torsional stiffness;• High torque capacity.

Shortcomings of a single U-joint:• Velocity and acceleration fluctuations, especially for large misalignments;• Lubrication is required to reduce friction and wear;• Protection from contamination (sealing) is required;• Shafts must be precisely located in one plane;• Backlash is difficult to control;• Static friction is increasing at very low misalignment (freezing), thus sometimes requiring an artificial misalignment in the assembly.

3.2.1b.2 KinematicsDue to the velocity fluctuations, the angular displacements of the

output shaft do not precisely follow those of the input shaft, but lead orlag, also with two cycles per revolution. The angular velocity variation isshown in Figure 9 for several operating (misalignment) angles �. Thepeak values of the displacement lead/lag, of input/output angular veloc-ity ratio, and of angular acceleration ratio for different are given inTable 1 [2]. As a qualitative guideline, for small �, up to ~10°, the devia-tions (errors) for maximum lead/lag angular displacements, for maxi-mum deviations of angular velocity ratios from unity, and for maximumangular acceleration ratios are nearly proportional to the square of �.

The static torque transmitted by the output shaft is equal to theproduct of the input torque and the angular velocity ratio.

The angular acceleration generates inertia torque and vibrations.The total transmitted torque is a sum of inertia torque (the product of theangular acceleration and the mass moment of inertia of the output shaft and masses associated with it) and the nominaloutput torque.

The inertia torque often determines the ultimate speed limit of the joint. The recommended speed limits vary dependingon �, on transmitted power, and on the nature of the transmission system. Recommended peak angular accelerations of thedriven shaft vary from 300 rad/sec2 to over 2000 rad/sec2 in power drives. In light instrument drives, the allowable angularaccelerations may be higher. For an accurate determination of the allowable speed, a stress analysis is necessary.

Example 1: Determining the Maximum Inertia TorqueA U-joint operates at 250 rpm with an operating angle � = 10°. Find the maximum angular displacement lead (or lag),

maximum and minimum angular velocity of output shaft and maximum angular acceleration of output shaft.If the system drives an inertial load so that the total inertial load seen by the output shaft (its own inertia and inertia of

associated massive rotating bodies) can be represented by a steel circular disc attached to the output shaft (radius r = 3 in.,thickness t = 1/4 in.), find the maximum inertia torque of the drive.

From Table 1 at � = 10°, the maximum displacement lead/lag = 0.439° = 26.3'. The maximum and minimum angularvelocity ratios are given as 1.0154 and 0.9848, respectively. Hence, the corresponding output shaft speeds are:

max = (250)(1.0154) = 254 rpm;

min (250)(0.9848) = 246 rpm;

According to Table 1, the maximum angular acceleration ratio is

max/�2 = 0.0306 for � = 10°.

� = [(250) (2�)] / (60) rad/sec = 26.18 rad/sec.

Hence, max = (0.0306)(26.18)2 = 21.0 rad/sec2. The weight, W, of the disc is given by W = � r2 t �, where � denotes thedensity of steel and is equal to 0.283 lb/in3.

where g = gravitational constant = 386 in/sec2.

Hence, I = [(2) (3)2] / [(2)(386)] = 0.0233 lb. in. sec2.

Inertia torque = (21.0) (0.0233) = 0.489 lb. in. This inertia torque is a momentary maximum. The inertia torque fluctuatescyclically at two cycles per shaft revolution, oscillating between plus and minus 0.489 lb. in.

When system vibrations and resonances are important, it may be required to determine the harmonic content (Fourierseries development) of the output shaft displacement as a function of the displacement of the input shaft. The amplitude ofthe mth harmonic (m > 1) vanishes for odd values of m, while for even values of m it is equal to (2/m) (tan 1/2�)m, where �denotes the operating angle.

3.2.1b.3 Joint Selection (Torque Rating)The torque capacity of the universal joint is a function of speed, operating angle and service conditions. Table 2 shows

use factors based on speed and operating angle for two service conditions: intermittent operation (say, operation for lessthan 15 minutes, usually governed by necessity for heat dissipation) and continuous operation.

The torque capacity of a single Cardan joint of standard steel construction is determined as follows:i. From the required speed (rpm), operating angle in degrees, and service condition (intermittent or continuous), find

the corresponding use factor from Table 2.ii. Multiply the required torque, which is to be transmitted by the input shaft, by the use factor. If the application involves

a significant amount of shock loading, multiply by an additional dynamic factor of 2. The result must be less than the staticbreaking torque of the joint.

iii. Refer to the torque capacity column in the product catalog and select a suitable joint having a torque capacity not lessthan the figure computed in (ii) above.

If a significant amount of power is to be transmitted and/or the speed is high, it is desirable to keep the shaft operatingangle below 15°. For manual operation, operating angles up to 30° may be permissible.

Example 2: Universal Joint Selection for Continuous OperationA single universal joint is to transmit a continuously acting torque of 15 lb. in., while operating at an angle of 15° and at

a speed of 600 rpm. Select a suitable joint.From Table 2 for continuous operation, the use factor is given as 68. Note that there are blank spaces in the Table. If the

combination of operating angle and speed results in a blank entry in the Table, this combination should be avoided. Therequired torque is (68) (15) = 1020 lb. in. There is no shock load and the dynamic factor of 2 does not apply in this case.

From the SDP/SI catalog, it is seen that there are two joints meeting this specification: A 5Q 8-D500 and A 5Q 8-D516,both with a torque capacity of 1176 lb. in. The first has a solid-shaft construction and the second a bored construction. Thechoice depends on the application.

Example 3: Universal Joint Selection for Intermittent Operation with Shock LoadingA single universal joint is to transmit 1/8 horsepower at 300 rpm at an operating angle of 15°. Select a suitable joint for

intermittent operation with shock loading.Here we make use of the equation:

Torque = Horsepower x 63,025/300 lb. in.

Hence, operating torque = (0.125)(63,025)/300 = 26.3 lb. in. From Table 2, for intermittent loads (300 rpm, 15°), the usefactor is 16. Due to shock loading, there should be an additional dynamic factor of 2. Therefore, the rated torque = (26.3) (16)(2) = 842 lb. in. Thus, the same joints found in the previous example are usable in this case.

Example 4: Determining the Maximum Speed of an Input ShaftA universal joint is rated at 250 lb. in., and operates at an angle of 12°, driving a rotating mass, which can be represented

(together with the inertia of the driven shaft) by a steel, circular disc, radius r = 6", thickness t = 1/2", attached to the drivenshaft. How fast can the input shaft turn if the inertia torque is not to exceed 50% of rated torque?

From Table 1, for � = 12°, we have max/�2 = 0.0442. The weight, W, of the disc is W = � r2 t �, where � denotes thedensity of steel which is 0.283 lb. in3.

Thus W = � (6)2(0.5) (0.283) = 16 lb. The polar mass moment of inertia, I, of the disc is given by

I = Wr2 / 2g = (16)(6)2 / (2)(386) = 0.746 lb. in. sec2.

The inertia torque = Imax = 50% of 250 lb. in. = 125 lb. in. Since Imax = (max / �2) • (�2I) = (0.0442)(0.746) �2 = 125, �2 =125 / 0.03297 = 3790.96 or � = 61.6 rad/sec = (61.6)(60) / 2� = 588 rpm.

Hence, if the inertia torque is not to exceed its limit, the maximum speed of the input shaft is 588 rpm. For joints madewith thermoplastic material, consult the SDP/SI catalog, which contains design charts for the torque rating of such joints.

3.2.1b.4 Secondary CouplesIn designing support bearings for the shafts of a U-joint and in determining vibrational characteristics of the driven

system, it is useful to keep in mind the so-called secondary couples or rocking torques, which occur in universal joints. Theseare rocking couples in the planes of the yokes, which tend to bend the two shafts and rock them about their bearings. Thebearings are thus cyclically loaded at the rate of two cycles per shaft revolution. The maximum values of the rocking torquesare as follows:

Maximum rocking torque on input shaft = Tintan�;Maximum rocking torque on output shaft = Tinsin�,

where Tin denotes the torque transmitted by the input shaft and � the operating angle. These couples are always 180° out ofphase. The bearing force induced by these couples is equal to magnitude of the rocking couple divided by the distancebetween shaft bearings.

For example, if the input torque, Tin is 1000 lb. in. and the operating angle is 20°, while the distance between supportbearings on each shaft is 6 in., the maximum secondary couple acting on the input shaft is (1000) (tan 20°) = 364 lb. in. andon the output shaft it is (1000) (sin 20°) = 342 lb. in. The radial bearing load on each bearing of the input shaft is 364/6 = 60.7lb. and it is 342/6 = 57 lb. for each bearing of the output shaft. The bearings should be selected accordingly.

It has been observed also that due to the double frequency of these torques, the critical speeds associated with universaldrives may be reduced by up to 50% of the value calculated by the standard formulas for the critical speeds of rotating shafts.The exact percentage is a complex function of system design and operating conditions.

3.2.1b.5 Joints in SeriesAs mentioned in paragraph 3.2.1b.1, universal joints can be used in series in order to eliminate velocity fluctuations, to

connect offset (nonintersecting) shafts, or both. Figure 8 shows a schematic of such an arrangement.In order to obtain a constant angular-velocity ratio (1:1) between input and output shafts, a proper phasing of the joints is

required. This phasing can be described as follows: two Cardan joints in series will transmit a constant angular velocity ratio(1:1) between two intersecting or nonintersecting shafts (see Figure 8), provided that the angle between the connectedshafts and the intermediate shaft are equal (� = �'), and that when yoke 1 lies in the plane of the input and intermediateshafts, yoke 2 lies in the plane of the intermediate shaft and the output shaft.

If shafts 1 and 3 intersect, yokes 1 and 2 are coplanar.When the above phasing has been realized, torsional and inertial excitation is reduced to minimum. However, inertia

excitation will inevitably remain in the intermediate shaft, because this shaft has the angular acceleration of the output shaftof a single U-joint (the first of the two joints in series). It is for this reason that guidelines exist limiting the maximum angularaccelerations of the intermediate shaft. Depending on the application, values between 300 rad/sec2 and values in excess of1000 rad/sec2 have been advocated. In light industrial drives, the allowable speed may be higher. For an accurate determi-nation of allowable speed, a stress analysis is necessary.

Example 5: Determining the Maximum Speed of an Input Shaft in a SeriesIn a drive consisting ot two universal joints in series, phased so as to produce a constant (1:1) angular velocity ratio

between input and output shafts, the angle between the intermediate shaft and input (and output) shaft is 20°. If the maxi-mum angular acceleration of the intermediate shaft is not to exceed 1000 rad/sec2, what is the upper limit of the speed of theinput shaft?

From Table 1, with � = 20°, we find max/�2 = 0.1250.

Since max = 1000 rad/sec2,

�2 = (max) / (0.1250) = (1000) / 0.1250) = 8000 rad/sec2.

Hence, � = 8000 = 89.4 rad/sec = (89.4)(60) / 2� = 854 rpm.

Hence, the speed of the input shaft should not exceed 854 rpm. When the joint angle is less than or equal to 10°, Figure10 can be used to compute the maximum speed or the maximum angular acceleration for a given input speed.

Example 6Same as problem 5, except operating angle is 10°. Here we can use Figure 10. The intersection of � = 10° and the 1000

rad/sec2 curve yields N � 1800 rpm. Hence, the speed of the input shaft should not exceed 1800 rpm. A more exactcalculation, as in Example 5, yields N = 1726 rpm. For practical purposes, however, the value obtained from Figure 10 isentirely satisfactory.

3.2.2 Selection Criterion for Misalignment-Compensating Couplings with Elastic ConnectorsFor this class of couplings, assuming linearity of the elastic connectors,

Fcom = kcome, (3)

where e is misalignment value, kcom = combined stiffness of the elastic connectors in the direction of compensation. In thiscase,

= e. (4)

Unlike couplings from Subclass (2a), Subclass (2b) (see p. T2-5) couplings develop the same radial force for a given mis-alignment regardless of transmitted torque, thus they are more effective for larger Tr. Of course, lower stiffness of the elasticconnectors would lead to lower radial forces.

3.2.2.1 Designs of Elastic Misalignment-Compensating CouplingsDesigns of Oldham couplings and U-joints with elastic connectors using high-performance thin-layered rubber-metal

laminates are described in [1, 3].K-Type flexible coupling, Figure 7, is kinematically similar to both Oldham coupling and to U-joint. By substituting an

elastomeric member in place of the conventional spider and yoke of U-joint or the floating member of Oldham coupling, inconstruction such as in the design shown in Figure 7, backlash is eliminated. Lubrication is no longer a considerationbecause there are no moving parts and a fairly large amount of lateral misalignment can be accommodated. The illustratedcoupling is available in the product section of this catalog. Please refer to Figure 11 for specific design data for four sizes ofthis type coupling. Figure 11b indicates that this coupling has high durability even with a combination of large lateral (offset)and large angular misalignments.

3.3 Torsionally Flexible Couplings and Combination Purpose Couplings [3]These two classes of couplings are usually represented by the same designs. However, in some cases only torsional

properties are required, in other cases both torsional and compensation properties are important and, most frequently, thesecoupling designs are used as the cheapest available and users cannot determine what is important for their applications.Accordingly, it is of interest to look at what design parameters are important for various applications.

3.3.1 Torsionally Flexible CouplingsTorsionally flexible couplings are used in transmission systems when there is a danger of developing resonance condi-

tions and/or transient dynamic overloads. Their influence on transmission dynamics can be due to one or more of thefollowing factors:

Reduction of Torsional Stiffness and, Consequently, Shift of Natural Frequencies.If resonance condition occurs before installation (or change) of the coupling, then shifting of the natural frequency can

eliminate resonance; thus dynamic loads and torsional vibrations will be substantially reduced.

Increasing Effective Damping Capacity of a Transmission by Using Coupling Material withHigh Internal Damping or Special Dampers.

When the damping of a system is increased without changing its torsional stiffness, the amplitudes of torsional vibrationsare reduced at resonance and in the near-resonance zone. Increased damping is especially advisable when there is a widefrequency spectrum of disturbances acting on a drive; more specifically, for the drives of universal machines.

Introducing Nonlinearity into the Transmission System.If the coupling has a nonlinear "torque-angular deformation" characteristic and its stiffness is much lower then stiffness

of the transmission into which it is installed, then the whole transmission acquires a nonlinear torque-angular deflectioncharacteristic. A nonlinear dynamic system becomes automatically detuned away from resonance at a fixed-frequency exci-tation, the more so the greater the relative change of the overall stiffness of the system on the torsional deflection equal to thevibration amplitude.

Introducing Additional Rotational Inertia in the Transmission System.This is a secondary effect since couplings are not conventionally used as flywheels. However, when a large coupling is

used, this effect has to be considered.

Realizing the above listed effects of a properly selected torsionally-flexible coupling requires a thorough dynamic analy-sis of the transmission system.

3.3.2 Combination Purpose CouplingsCombination purpose couplings do not have a special com-

pensating (floating) member. As a result, compensation of mis-alignment is accomplished, at least partially, by the same mode(s)of deformation of the flexible element which are called forth bythe transmitted payload.

The ratio of radial (compensating) stiffness kcom and torsionalstiffness ktor of a combination purpose flexible coupling can berepresented as [1,3]

= , (5)

where Rex is external radius of the coupling. The "Coupling De-sign Index" A (Figure 13f) allows one to select a coupling designbetter suited to a specific application. If the main purpose is toreduce misalignment-caused loading of the connected shafts andtheir bearings, for a given value of torsional stiffness, then thelowest value of A is the best, together with large external radius.If the main purpose is to modify the dynamic characteristics ofthe transmission, then minimization of ktor is important.

Some combination purpose couplings are shown in Figure12. The "modified spider" coupling (Figure 12b) is different fromthe conventional spider (jaw) coupling shown schematically inFigure 12a by four features: legs of the rubber spider are ta-pered, instead of staight; legs are made thicker even in the small-est cross section, at the expense of reduced thickness of bosseson the hubs; lips on the edges provide additional space forbulging of the rubber when legs are compressed, thus reducingstiffness; the spider is made from a very soft rubber. All thesefeatures lead to substantially reduced torsional and radialstiffnesses while retaining small size, which is characteristic forspider couplings.

Plots in Figure 13 (a-d) give data for some widely used cou-plings on such basic parameters as torsional stiffness ktor, radialstiffness kcom, external diameter Dex, and flywheel moment WD2(W is weight of the coupling). Plots in Figure 13 (e-f) give deriva-tive information: ratio kcom / ktor, and design index A. All theseparameters are plotted as functions of the rated torque.

Data for "toroid shell" couplings in Figure 13 are for the cou-pling as shown in Figure 12 (c) (there are many design modifica-tions of toroid shell couplings). The "jaw coupling" for T = 7 Nm inFigure 13 (f) (lowest torque point on jaw coupling line) has a four-legged spider (z = 4), while all larger sizes have z = 6 or 8. Thisexplains differences in A (A � 1.9 for z = 4, but A = 1.0 ~ 1.3 for z= 6,8). Values of A are quite consistent for a given type of cou-pling. The variations can be explained by differences in designproportions and rubber blends between the sizes.

Using plots in Figure 13, one can more easily select a cou-pling type whose stiffnesses, inertia, and diameter are best suitedfor a particular application. These plots, however, do not addressissues of damping and nonlinearity. Damping can be easily modi-fied by the coupling manufacturer by a proper selection of theelastomer. As shown previously, high damping is very beneficialfor transmission dynamics, and may even reduce thermal expo-sure of the coupling, as shown in [1,3]. More complex is the is-sue of nonlinear characteristics; a highly nonlinear (and very com-pact) coupling based on radial compression of cylindrical rubberelements is described in [1]. Couplings represented in Figure 13are linear or only slightly nonlinear.

3.3.2.1 Miscellaneous Combination Purpose Couplings

3.3.2.1a Flexible ShaftsFlexible shafts are relatively stiff in torsion but very compliant in bending and lateral misalignments. A good example of

this is in their use on automotive speedometer drives.A flexible shaft consists of:

a. Shaft - the rotating element comprising a center wire with several wire layers wrapped around it in alternatingdirections.

b. Casing - the sleeve made from metal or nonmetals to guide and protect the shaft and retain lubricants. Flexibleshafts can be supplied without casing when used for hand-operated controls or intermittent-powered applications.

c. Case End Fitting - connects the casing to the housing of the driver and driven equipment.

d. Shaft End Fitting - connects the shaft to the driving and driven members. Flexible shafts as shown in the SDP/SIcatalogs [4] are often substituted in place of more expensive gear trains and universal joints in applications wherethe load must be moved in many directions. They are extremely useful where the load is located in a remoteposition requiring many gear and shafting combinations.

The basic design considerations are torque capacity, speed, direction of rotation, bend radii and service conditions.Torque capacity is a function of the shaft size. Operating conditions must be considered in power drive applications such asstarting torque, reversing shocks, and fluctuating loads. These conditions constitute overloads on the shaft. If they aresubstantially greater than the normal torque load, a larger shaft must be selected. Since, in power applications, torque isinversely proportional to speed, it is beneficial to keep the torque down, thereby reducing shaft size and cost.Ordinarily, speeds of 1750 to 3600 rpm are recommended. However, there are applications in which shafts are operatingsuccessfully from 600 to 12,000 rpm. The general formula for determining maximum shaft speed is:

N = (7200) / �d, where N = rpm, d = shaft diameter in inches. (6)

Flexible shafting for power transmission is wound for maximum efficiency when rotating in only one direction - thedirection which tends to tighten the outer layer of wires on the shaft. Direction of rotation is identified from the power sourceend of the shaft. Torque capacity in the opposite direction is approximately 60% of the "wind" direction. Therefore, if thepower drive shaft must be operated in both directions, the reduced torque capacity will require a larger shaft than wouldnormally be selected for operation in the wind direction.

Because flexible shafts were developed primarily as a means of transmitting power where solid shafts cannot be used,most applications involve curves. Each shaft has a recommended minimum operating radius which is determined by theshaft diameter and type. As the radius of curvature is decreased, the torque capacity also decreases and tends to shortenshaft life.

Lastly, service conditions such as temperature present no special problems to flexible shafts when operating in the -65°Fto +250°F range. Plastic casing coverings are able to cover this temperature range and provide additional protection fromphysical abrasion as well as being oil and watertight.

3.3.2.1b Uniflex CouplingsSometimes it is desirable if not essential that a flexible shaft coupling be as short as possible and still retain most of the

features previously described. Figure 12e illustrates such a coupling, available in the SDP/SI catalog [4].The "flexible shaft" center section consists of three separately wound square wire springs. Individual spring layers are

opposingly wound to provide maximum absorption of vibration, load shock, and backlash. The hubs are brazed to the springsfor maximum strength. Design data is available in Table 3 as well as in the Uniflex catalog page of the SDP/SI catalog.The maximum torque and/or H.P. Capacity from Table 3 must be divided by the Service Factor (S.F.) dependent on the loadcharacter as follows:

a. Light, even load - S.F. = 1.0;b. Irregular load without shock, rare reversals of direction - S.F. = 1.5c. Shock loads, frequent reversals - S.F. = 2.0

Uniflex Selection Procedure:

a. Select the service factor according to the application.b. Multiply the horsepower or torque to be transmitted by the service factor to obtain rating.c. Select the coupling with an equivalent or slightly greater horsepower or torque than shown in Table 3.

3.3.2.1c Jaw and Spider CouplingsJaw type couplings, Figures 12a, 12b consist of two metal hubs which are fastened to the input and output shafts (see

product pages in this catalog). Trapped between the hubs is a rubber or Urethane "spider" whose legs are confined betweenalternating metal projections from the adjacent hubs. The spider is the wearing member and can be readily replaced withoutdismantling adjacent equipment. The coupling is capable of operating without lubrication and is unaffected by oil, grease, dirtor moisture. Select the proper size for your application from Table 4 and the selection instructions. The Service Factors are,essentially, the same as for the Uniflex coupling.

Jaw and Spider Type Coupling Selection Procedure:

a. Select the Service Factor according to the application.b. Multiply the horsepower or torque to be transmitted by the service factor to obtain rating.c. Select the coupling series from Table 4 with an equivalent or slighlty greater horsepower or torque

than the calculated value in b.d. Turn to the product section page illustrating the same coupling and make your specific selection in that

number series.

3.3.2.1d Sleeve Type Coupling (Geargrip)A sleeve type coupling consists of two splined hubs with a mating intermediate member of molded neoprene. Because of

its construction features, it is capable of normal operation with angular shaft misalignments up to 2°.Lubrication is not required. All parts are replaceable without disturbing adjacent equipment provided sufficient shaft length is

allowed by sliding coupling hubs clear of the sleeve member during disassembly. Select the proper size for your applicationfrom Table 5 and follow the selection instructions.

Sleeve Type Coupling Selection Procedure

a. Determine motor characteristics.b. Determine service conditions.c. Select the coupling model with an equivalent or slightly greater horsepower than the calculated value in b in Table 5.d. Turn to Geargrip couplings in the product section and select the specific assembly or individual components

in that model number.

Other types of couplings are also available and are fully described along with technical specifications in the SDP/SIcatalogs dealing with couplings [4].
