Heavy Duty Wedge V-Belts

Wedge belts have been the result of a continuous thrust by the manufacturers and users on higher power transmissions with reduced space requirements. Wedge belts can transmit higher power to the extent of 1.5 to 2 times the classical belts with the same top width. This has been achieved by dimensional changes, apart from better cord construction used and the optimum placement of the cord line which provides the best support to the cord while in motion. During manufacturing we pre-stretch the cord before building into the belt. It offers lower stretch properties in the drive. This way we are able to reduce minimum installation and take up allowances significantly. For the efficient performance of wedge drive it is essential that the proper tension be maintained in the drive, failure to maintain the same will render the purpose of wedge belts ineffective.

Features:

•  Top width to height ratio is 1.2:1

•  Temperature range: -18 to +80

•  Maximum recommended belt speed is 30 m/s*

•  Less deformation of the belt cross-section when in contact

• with the pulleys ensures better contact between the belt flanks and the pulley grooves
• Antistatic, Oil and Heat resistant

Applications:

Primarily used as replacement on industrial drives. The classical belts are recommended in special applications such as V-flat drives. In the same manner these belts are advantages where reverse idlers have to be used, because of smaller heights.

Standards, Dimensions & Product Range:

We manufacture the entire range of wedge belts. The nominal length for SP wedge belts is designated as pitch length (Lp) in millimeter
