5115 Transmission Error in Helical Synchronous Belt Drives in Bidirectional Operation : Influence of Error in Belt Side Face, Experimental Result

Abstract

The transmission error in a helical synchronous belt drive using flanged pulleys under the quasi-static condition and transmitted torque was investigated experimentally for the case where the pulley was rotated in bidirectional operation and the pulley speed ratio was 1:1. The experimental results of transmission error agree well with the calculated results, thereby confirming the applicability of the proposed theoretical analysis for transmission error. Transmission error especially is found to be generated by the error in belt side face when the belt comes into contact with the pulley flange, and that over a period of one rotation of the belt occurs.
