For a flat belt drive, the friction between the belt and pulley for a small segment of belt is =µ×𝑅, while for a V belt/sheave with a 38° angle, the friction would be = ×µ×𝑅 o The same hub load and stress in the tensile members gives Vbelts nearly 3x the friction of flat belts. For a 38° angle, assuming all other characteristics are the same. Advantages of VBelts Reduced ...
