Abstract  To measure the eccentricity of the mechanical eccentric shaft parts, a method to measure the eccentricity is proposed.Based on reversal process and least square method,the main factors affecting the measurement accuracy are analyzed. The influence of the measurement position on the measurement accuracy is mainly discussed. Eccentricities and errors of different measurement locations are analyzed with the aid of digital simulation of robot joint reducer, and the error curve is given. It provides some technical supports for the actual measurement process, and therefore are beneficial for improving measurement accuracy.
