What does the pulley correction factor, Cp, account for in the calculation of a flat belt's allowable tension, (F1)a = b*Fa*Cp*Cv?
Explanation
The allowable tension for a belt is derated based on operating conditions to ensure a reasonable service life. The pulley correction factor, Cp, specifically addresses the fatigue damage caused by repeated bending of the belt as it wraps around the pulleys. Smaller pulleys cause more severe bending stress, leading to a lower Cp value and a lower allowable tension.
