V-belt drive misalignment exists when the driver and driven sheaves are not properly aligned. Misalignment can take either the form of angular or parallel (offset) misalignment, or a combination of ...

Over-tensioning shortens not only the life of V-belts but also that of the sheaves, electric motor, and driven equipment bearings. In extreme cases, it can even bend or break a motor shaft.

The most common reasons for belt failure are improper belt tension (too loose or too tight), poor alignment, pulley damage or distortion, environment (excessive heat and ozone), and using an improper ...
