摘　　要：成形磨齿通常是齿轮切削加工的最后一道工序,磨后齿面残余应力对齿轮的服役性能与寿命影响显著。传统基于X射线衍射方法的齿轮残余应力测量方法并未考虑齿面特殊几何特性,导致测量精度低。此外,磨齿工艺参数与磨前齿面状态对磨齿残余应力的影响规律不清。因此,本文提出一种考虑齿轮特殊几何特性的齿面残余应力测量方法与辅助工装夹具,并建立基于磨齿工艺参数的齿面残余应力预测模型,最后探讨了磨前齿面残余应力对磨后残余应力的影响。本文为非平面残余应力的测量提出了新方法,所提的齿面残余应力预测方法能够指导实际生产。Forming gear grinding is usually the last process of gear cutting,and the residual stress on the tooth surface after grinding has a significant effect on the service performance and life of the gear.The traditional measurement method of residual stress of gear based on X-ray diffraction method does not consider the special geometric characteristics of the tooth surface,resulting in low measurement accuracy.In addition,the influence of grinding process parameters and tooth surface state before grinding on residual stress of tooth grinding are unclear.Therefore,this paper proposes a measurement method for residual stress and auxiliary fixture considering the special geometric characteristics of gears,and establishes the residual stress prediction model of tooth surface based on grinding process parameters.Finally,the influence of residual stress before grinding on residual stress after grinding of tooth surface is discussed.In this paper,a new method for the measurement of non-planar residual stress is proposed.The proposed method for the residual stress prediction of tooth surface can be adopted to guide the actual production.
