General Characteristics
Misalignment SolutionsMisalignment is the cause of breakage in bearings, as well as the other components of the machine (seals, gaskets, gears), which are not normally prepared for the inflection introduces to the axis. Which is primary features; elasticity, misalignment compensation, and shock absortion, the Gummi Flexible is the solution in reducing the efforts of the machines components while increasing their useful life.
Simple InstallationThe replacement is simpler and faster because it is comprised of only one rubber element. Using smaller alignment tolerances allows the element to extend the working life of its elastic center. It is not necessary to move the parts in order to replace the flexible element.
Symmetry - Security - BalanceSince the rubber element does not have any cuts in the elastic center, it there for has a guaranteed balance and no safety or security issues.
Assured qualityManufactured under the strict Quality System, and produced using only the highest quality raw materials.
Vibration and Shock Load DampeningThe ability to absorb torsional vibrations and shocks provides for an extended working life of the equipment or machine. The measurement of vibrations that are transmitted in a system, from one side to the other, it is around 70%, which is minimized with the elastic center of the coupling´s to ability to absorb the shock loads and vibrations.
EconomyThe working life capacity in the applications spare parts increases, reducing costly down time, minimizing the cost of replacement components, lubricants and inventory. The elastic center of the coupling works for a prolonged period of time without needing to be replaced.
No need to LubricateAs a result of its design and constructive characteristics, the element does not require lubrication.

Table I Maximum air Temperature: 176 F (80 C)
The information in the catalog is subject to modifications without warning
Once the value is obtained from the formula, go to Table I below, and read down on the RPM column until the RPM for the case engine is found. Read across until the closest number to the result obtained from the formula is found. Then read up to the top of the chart to find the recommended coupling.
Example A :
Generator driven by a Diesel Engine (370 HP & 1000 RPM)
HP x Fs = 370 x 2.5 = 925
Look up under the RPM column in Table I below until you reach 1000 RPM. Then move to the right until you find the closest value to the calculated 925 (in this case it would be 950). Move up to the top line on the chart and you will read <> A 140, which is the recommended coupling size for this application.
Nominal H.P.All the reading between that fall below the heavy black line correspond to Flexible Couplings models with hubs that are fitted on the flanges and dynamically balanced.

1.0 thru 1.51.75
2.0 or more
1.01.25
Same as LSS
TABLE II BService factors for engine drives are those required for applications where good flywheel regulation prevents torque fluctuations greater then 20%. For drives where torque fluctuations are greater ro where the operation is near a serious critical or torsional vibration, mass elastic study is necesary.
To use Table II B, fisrt determine application service factro from Table II Use the fastor to determine ENGINE Service Factor from Table II B When service factor from Table II is greater than 2.0, refer complete application details to the Factory for engineering review.

For motor driven reducers with resilient high speed and low speed shaft coupling, refer to Table II A. For motors with brakes, select the coupling based on the higher of the two torque ratings.For balanced opposed design, divide number of cylinders by two and use abova table for reciprocating compresors.

Taper Lock Bushings
The electrometric rubber used in Gummi´s coupling generally providefor a good resistance to chemical products or aggresive agents. In such cases in which a constant highly aggresive contact is encountered, the use of a special coating on the rubber element is recommended.When ordering, please indicated which agents may be in encountered,and on what basis.

In the initial assembly, the shafts must be aligned. Leave a gap between the inner flanges of both hubs, this distance is indicate as "C" in Table IV .
Leave a gap between the inner flanges of the hub faces as indicated in the drawing to the right.
It the bolts are over tightened as shown in the figure to the right, the compressed rubber element will shear during operations. If the bolts are not tightened correctly, start up toque will detach the inner flange.
For a precise tightening adjustment, we recommend that you use an Impact Wrench with and air pressure gauge, which will allow for the tightening according to the air pressure torque values indicated in Table V above. For the adjustment of taper lock hubs and or flywheels, use only and Impact Wrench.
If an impact wrench is not available, use a plain wrench and proceed as follows:1- Tighten until the washer is flattened.2- Tighten bolts 1 ½ turns after washer is flattened.
