Analysis of Several Problems in Belt Drive Design

Some important formulas in belt drive design are not proved in the textbooks and manuals of machine design,and this will not help the students to understand the contents concerned.To solve this problem,several formulas are analyzed and derived,including the formula indicating the relationship between belt length and wheel center distance,the Euler's formula of flexible body friction,the formulas to calculate bending stress and centrifugal tensile stress.The issues such as drive ability comparison between V belt and flat belt,the calculation of belt number,which are not thoroughly explained in textbooks and manuals,are discussed here.
