Good alignment of pulleys prior to belt installation is important. The pulleys may be aligned by placing a straight edge or cord along the edges. The shafts must also be parallel and in the same plane. 3. BELTS When pulleys have been correctly positioned on the shafts, the belts can be installed to complete the drive. The drive centre distance

Correct accurate installation of V-Belt Pulleys is essenial to provide long life of the belts. Pulley alignment and parallelism are very important as any misalignment of the pulleys will cause unequal loading in the belt and cause edge we the belt. Pulley alignment can be checked by placing a straight edge across the outside edge of the

CAST- IRON V-BELT PULLEYS All V-belt pulleys are compliant with current legislation and are made of cast iron GG 20with protective phosphate. Running in normal standard, the pulleys are statically balanced and this is sufficient for peripheral speeds up to 25 m/s. For higher speeds is essential dynamic balancing can be provided on request.

V-Belts and Pulleys J636_201211 This specification covers standard dimensions, tolerances, and methods of measurement of V-belts and pulleys for automotive V-belt Measure the section With a ruler measure the top width of the belt (widest part of the vee) and then the thickness of the belt. See image below.

Typically, v-belt drives operate between 1,500 to 6,000 ft/min, with 4,500 ft/min the ideal capacity for standard belts. Some narrow v-belts can operate at speeds of up to 10,000 ft/min, but these pulleys must be dynamically stabilized.

A pulley consists of a wheel turning on a fixed axle, with a groove along the edges to guide a rope or cable. It is also known as a machine made with a rope, chain or belt wrapped around a grooved wheel. A pulley modifies the direction of the force, making it easier to lift things. It is a system of ropes and wheels that achieve the purpose of making an object easier to lift.
