Abstract
This paper was investigated the influence of transmitted torque, installation tension, pitch difference, and pulley alignment error on the transmission error in a helical synchronous belt having the error in the belt side face for the case where the flanged pulley was rotated in bidirectional operation under the quasi-static condition and the pulley speed ratio was 1:1. The transmission error in bidirectional operation increases when the transmitted torque increases. The transmission error can be reduced when the installation tension is set high, and when the pitch difference on the driving side is made small to some extent than that on the driven side. In addition, the rotation transmission accuracy is improved when the alignment between the driving and driven pulleys in the axial direction is set so that the belt on the driving side comes into contact with the pulley flange early.
