Rotational Transmission Accuracy in Traction Drive of Concave and Convex Roller Pair

Abstract

This paper presents a study on the rotational transmission accuracy in the traction drive of a concave and convex roller pair. The simultaneous measurements of specific sliding, transmitted torque and roller surface temperature in the contact between a concave and convex roller pair under different running conditions were carried out by using a concave and convex roller testing machine and measuring system which had been developed by the authors. The effects of the torque, roller speed and contact pressure on specific sliding, rotational transmission error (variation of specific sliding) and roller surface temperature were investigated.
