Research of Optimization of Grinding Parameter of Hypoid Gear based on Orthogonal Experiment

Abstract

Grinding machining is the final procedure in the machining process of the hypoid gear. The grinding quality directly affects the meshing performance and machining accuracy of the gear pair. In view of the poor quality stability of the rear axle hypoid gear grinding machining, the orthogonal experiment is carried out with the spindle speed, load torque and the number of grinding cycles as the influencing factors. Through the influence of the above parameters on the tooth surface roughness, combined with the range analysis, the combination of grinding parameters with the smallest surface roughness is determined and tested. The test results show that the optimized grinding parameter combination can effectively reduce the tooth surface roughness and improve the grinding quality, and also provide a reference for the selection of grinding tooth processing parameters.
