A Study on Strength of Toothed Belt : 2nd Report, Influence of Pitch Difference on Load Distribution

Abstract

In this paper, the load distribution of toothed belt whose pitch is different from that of pulley is discussed theoretically and experimentally. From this study the following conclusions have been obtained : 1) The pitch difference exerts an important influence on the load distribution, so the most suitable pitch difference should be chosen in consideration of the transmissive load, the modulus of elasticity of the belt, the compliance of the bled tooth, the coefficient of friction between belt and pulley. 2) The effectiveness of the theoretical prediction on load distribution is proved by the experimental results.
