V-belts are used in belt drives, and this type is the most popular among all belts. Unlike flat belts, they are trapezoidal or wedge-shaped in cross-section. As in other belt drives, the torque from the driving V-pulley to the belt and from it to the driven pulley is carried out by frictional forces. But in the V-belt transmission, the side surfaces of the belt are the workers. In this case, the contact patch is much larger than in a flat belt. This means more and the friction force and, consequently, the transmitted torque. To increase the contact patch, it is not necessary to increase the diameter of the pulley. It is wiser, from the point of view of the dimensions of the structure, to choose a pulley with a small diameter, but with several belts.

The v-belts usage

When installing the belt drive, parameters such as alignment and tension of the INA brand V-Belt are very important. Deviation from the design values ​​should not exceed the tolerances according to the manufacturer's recommendations.
