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 ...

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 V-ribbed concept combines some of the best features of flat belts and V-belts. It employs what is essentially a flat belt with a series of V-shaped ribs running the length of the belt on the ...

Pulsating loads, such as those generated by internal combustion engines and compressors, present special problems for V-belt drives. Intermittent forces tend to produce a whipping motion in the belts ...
