摘　　要：研齿是准双曲面齿轮加工工艺中最后一道精整加工工序,其研磨质量直接影响齿轮副的啮合性能和加工精度。针对后桥准双曲面齿轮研齿质量稳定性差的问题,以主轴转速、载荷转矩以及研磨循环次数为影响因素进行正交试验,通过分析上述参数对齿轮表面粗糙度的影响,结合极差分析,确定出齿面粗糙度最小的研磨参数组合,并进行了试验验证。试验结果表明,优化后的研磨参数组合可有效降低齿面粗糙度,提高研磨质量。研究为研齿加工参数选择提供一定的参考。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.
