Foreword

A well designed belt drive will transmit pow-er for many years with a minimum of main-tenance . Although they have been around for a long time, belts are still a very efficient and cost-effective method for transmitting power from one component to another .

The evolution of belts has been remark-able . New materials, designs and manufac-turing methods have increased working load limits and extended belt life .

SKF offers a complete assortment of both standard and high performance belts that can be implemented in many different applications .

The most common V and timing belts are part of this manual . The power ratings listed here are the same as those used in our soft-ware programs . However, there will be small differences in the results because the soft-ware will interpolate values if speeds or di-ameters fall between those listed in the ta-bles . As a result, SKF recommends using the belt selection program available for down-load at www .skfptp .com .

4SKF the knowledge engineering company

From the company that invented the self-align ing ball bearing more than 100 years ago, SKF has evol ved into a knowledge engin eering company that is able to draw on five technology platforms to create unique solutions for its custom ers. These platforms include bearings, bearing units and seals, of course, but extend to other areas including: lubricants and lubrication sys tems, critical for long bearing life in many appli cations; mecha tronics that combine mech anical and electron ics knowledge into systems for more effective linear motion and sensorized solu-tions; and a full range of ser vices, from de-sign and logistics support to con dition moni-toring and reliability systems.

Though the scope has broadened, SKF continues to maintain the worlds leadership in the design, manufacture and marketing of rolling bearings, as well as complementary products such as radial seals. SKF also holds an increasingly important position in the market for linear motion products, high-precision aerospace bearings, machine tool spindles and plant maintenance services.

The SKF Group is globally certified to ISO 14001, the international standard for envi r-o n mental management, as well as OHSAS 18001, the health and safety manage ment standard. Individual divisions have been ap proved for quality certification in ac cord-ance with ISO 9001 and other customer specific requirements.

With over 120 manufacturing sites world-wide and sales companies in 70 countries, SKF is a truly international corporation. In addition, our distributors and dealers in some 15 000 locations around the world, an e-business marketplace and a global distri bution system put SKF close to cus-tomers for the supply of both products and services. In essence, SKF solutions are avail-able wherever and whenever customers need them. Over all, the SKF brand and the corporation are stronger than ever. As the knowledge engin eering company, we stand ready to serve you with world-class product competencies, intellectual resources, and the vision to help you succeed.

Mechatronics Services

Evolving by-wire technology SKF has a unique expertise in the fast-growing by-wire technology, from fly-by-wire, to drive-by-wire, to work-by-wire. SKF pioneered practical fly-by-wire technology and is a close working partner with all aerospace industry leaders. As an example, virtually all aircraft of the Airbus design use SKF by-wire systems for cockpit flight control.

SKF is also a leader in automotive by-wire tech-nology, and has partnered with automotive engin-eers to develop two concept cars, which employ SKF mecha tronics for steering and braking. Fur-ther by-wire develop ment has led SKF to produce an all-electric forklift truck, which uses mecha-tronics rather than hydraulics for all controls.

5Harnessing wind powerThe growing industry of wind-generated electric power provides a source of clean, green electricity. SKF is working closely with global industry leaders to develop efficient and trouble-free turbines, providing a wide range of large, highly specialized bearings and condition monitoring systems to extend equip-ment life of wind farms located in even the most remote and inhospitable environments.

Working in extreme environmentsIn frigid winters, especially in northern countries, extreme sub-zero tempera-tures can cause bearings in railway axleboxes to seize due to lubrication star-vation. SKF created a new family of synthetic lubricants formulated to retain their lubrication viscosity even at these extreme temperatures. SKF knowledge enables manufacturers and end user customers to overcome the performance issues resulting from extreme temperatures, whether hot or cold. For example, SKF products are at work in diverse environments such as baking ovens and instant freezing in food processing plants.

Developing a cleaner cleanerThe electric motor and its bearings are the heart of many household appli-ances. SKF works closely with appliance manufacturers to improve their prod-ucts performance, cut costs, reduce weight, and reduce energy consumption. A recent example of this cooperation is a new generation of vacuum cleaners with substantially more suction. SKF knowledge in the area of small bearing technology is also applied to manufacturers of power tools and office equipment.

Maintaining a 350 km/h R&D labIn addition to SKFs renowned research and development facilities in Europe and the United States, Formula One car racing provides a unique environment for SKF to push the limits of bearing technology. For over 60 years, SKF prod-ucts, engineering and knowledge have helped make Scuderia Ferrari a formid-able force in F1 racing. (The average racing Ferrari utilizes around 150 SKF components.) Lessons learned here are applied to the products we provide to automakers and the aftermarket worldwide.

Delivering Asset Efficiency Optimization Through SKF Reliability Systems, SKF provides a comprehensive range of asset efficiency products and services, from condition monitoring hardware and software to maintenance strategies, engineering assistance and machine reliability programmes. To optimize efficiency and boost productivity, some industrial facil ities opt for an Integrated Maintenance Solution, in which SKF delivers all ser vices under one fixed-fee, performance-based contract.

Planning for sustainable growth By their very nature, bearings make a positive contribution to the natural environment, enabling machinery to operate more efficiently, consume less power, and require less lubrication. By raising the performance bar for our own products, SKF is enabling a new generation of high-efficiency products and equipment. With an eye to the future and the world we will leave to our children, the SKF Group policy on environment, health and safety, as well as the manufacturing techniques, are planned and implemented to help protect and preserve the earths limited natural resources. We remain committed to sustainable, environmentally responsible growth.

Selection guide for SKF V-belts

Selection procedure and formulaeExample:Driver: 45 kW electric motor, 1 440 r/min, direct online start .Driven: Fan, 550 r/minService: 24 hours/dayApproximate distance between centres = 900 mmTensioning method: SKF pen tester

Service factor (C1 2)Service factors describe the severity of drive conditions . Refer to tables 2 and 3 on page 16 .

Example: Medium duty class, heavy start

C2 = 1,4

For speed increasing drives, use correction factors in table 1 on page 16 .

Design power (P2 d)Multiply drive power and service factor C2 to get the design power .

Pd = Pr C2

wherePd = design power [kW]Pr = motor rated power or power

absorbed by the load [kW]C2 = service factor

Example: Pd = 45 1,4 = 63 kW

Belt cross section3 Refer to diagrams 1, 2, 3 on pages 17 and 18 for the appropriate belt cross sec-tion based on speed and design power .

Example: Selected section SPB

Required speed ratio (I4 r)Divide speed of faster shaft with speed of slower shaft to get the required pulley speed ratio .

r/min (faster shaft) Ir = r/min (slower shaft)

Example:

1 440 Ir = = 2,62 550

A . If selected cross section is SPA/SPA-5 XP/XPA, SPB/SPB-XP/XPB, SPC/SPC-XP/XPC, 5V/5V-XP/5VX or 8V/8V-XPChoose the corresponding centre distance based on the required speed ratio by re-ferring to tables 4a to 4p on pages 20 to 35 to get:

Belt datum length (Ld)Centre distance (CC)Datum diameter of pulleys (d, D)

Example: Centre distance table for section SPB is available on pages 23, 24 and 25 .

Speed ratio: 2,62Belt datum length: 2 990 mmCentre distance: 941 mmD = 500 mmd = 190 mm

Continue with step 10 .

5 B . If another type of V-belt is selected, where centre distance tables are not availableContinue with step 6 .

Pulley datum diameters (d, D)6 Try to use standard pulley diameters .

Refer to table 5a or 6a on pages 36 to 39 to get the recommended diameter for small pulleys (d)

Refer to speed ratio table 5b or 6a on pages 36 to 39 to get the diameter for large pulleys (D)

Centre distance preliminary (CCp)7 Determine preliminary centre distance between pulleys .

Recommended: CCp min: 0,7 (D + d) CCp max: 2 (D + d)

whereD = large pulley diameterd = small pulley diameter

Belt datum length (L8 d)Calculate the belt length based on preliminary centre distance .

1,57 (D + d) (D d)2Ld = 2 CCp + 4 CCp

whereLd = belt datum length [mm]CCp = preliminary centre distance [mm]D = large pulley diameter [mm]d = small pulley diameter [mm]

Choose the closest available belt length from belt tables on pages 81 to 99 .

Centre distance (CC)9 Calculate actual centre distance based on selected belt length Ld .

JJJJJJ

a + Pa2 8 (D d)2CC = 8

wherea = 2 Ld (D d)Ld = selected belt datum length [mm]D = large pulley diameter [mm]d = small pulley diameter [mm]

115

Belt basic power rating (P10 b)Refer to power rating tables for selected belt type on pages 41 to 62 to get the power rating values . The total belt basic power rating consists of basic power rating + power rating based on speed ratio .

Example: Pb = 11,9 + 0,72 = 12,62 kW

Correction factors (C11 1, C3)Refer to table 8 for belt length correc-tion factor C1 and table 7 for arc of con-tact correction factor C3 .

Example: Belt length correction factor C1 = 0,97 (interpolated)Arc of contact correction factor C3 = 0,96

Belt power rating (P12 r)Multiply belt basic power rating with C1 and C3 to get the actual belt power rating .

Pr = Pb C3 C1

Example: Pr = 12,62 0,97 0,96 = 11,75 kW

Number of belts (N)13 Divide drive power (design power) by power rating of selected belt to get the required number of belts .

Pd N = Pr

Round up to first integer .

Example:

63 N = = 5,4 11,75

Installation and take-up allowances14 Installation allowance MIA is minimum distance needed to decrease the CC dis-tance in order to be able to install the belt . Take-up allowance MTA is mini-mum distance needed to increase the CC distance in order to tension the belt .Refer to tables 10a and 10b on page 63 to get the values .

Example:

MIA = 25 mmMTA = 45 mmCc min = 941 25 = 916 mmCc max = 941 + 45 = 986 mm

Belt tension15 Refer to tables 11 to 18 on pages 64 to 71 to get the recommended tension values for selected belts or follow in-struction in the tensioning section to calculate tension specifically for a drive .

Example:d = 190 mmspeed = 1 440 r/minBelt section SPBTensioning method: SKF pen testerDeflection force for a used run-in belt = 5,5 kgDeflection force for a new belt = 8,2 kg
