Rubber V-belts are used in belt drives and have a trapezoidal cross-section. Thanks to this shape, the friction between the belt flanks is significantly greater than with a flat belt.
The V-belts are made of rubber in a
endless manufacturing and have a polyester tension member. The use of V-belts makes it possible to transmit significantly greater torque than with flat belts, while requiring the same amount of space. In practice, various types of V-belts are used.
Classic V-belts are standardly covered with a fabric that protects against abrasion and are manufactured in profiles 5, 6, 8, 10, 13, 17, 20, 22, 25, 32, and 40.
Narrow V-belts also have a cover but are characterised by improved power transmission and are manufactured in profiles SPZ, SPA, SPI, and SPC.
Banded V-belts consist of several individual V-belts connected by a common cover plate. They are manufactured in profiles 3V/9J, 3VX/9J, 5V/15J, 5VX, 8V/25J, A/HA, B/HB, C/HC, D/HD, SPA, SPB, SPC, SPZ, XPA, XPB, XPC and XPZ.
Wide V-belts are raw-edged and moulded-tooth and are available in profiles 3/5, 13/6, 17/5, 17/6, 21/6, 22/8, 24/8, 26/8, 28/8, 30/10, 32/10, 37/10, 41/13, 42/12, 47/12, 47/13, 52/16, 55/16, 65/20, 70/18 and 83/23.
