摘　　要：大型齿圈成形磨削时不同的磨削余量会影响磨削力及磨削热的大小,从而引起不同的磨削变形,合理的余量分配对于保证齿圈加工质量意义重大。基于磨削接触区域模型、磨削力模型和磨削移动热源理论,分析了齿圈成形磨削在热力耦合作用下的变形预测仿真流程,建立了磨齿余量分配模型。以某大型齿圈为研究对象,以变形控制为目标,对不同磨齿余量进行了磨削变形仿真,得到了较优的余量分配值。研究方法对提高齿圈成形磨削加工精度具有一定的借鉴意义。The grinding allowance of large gear ring forming grinding will affect the grinding force and grinding heat,resulting in different grinding deformation,reasonable balance of allowance distribution means a lot to the quality of gear ring. Based on the grinding contact zone model,the grinding force model and the grinding and moving heat source theory,the simulation process of the deformation prediction of the ring gear grinding under the thermo-mechanical coupling is analyzed,and the optimization model of the gear grinding balance distribution is established. Taking a large gear ring as the research object,with the deformation control as the goal,the deformation of several sets of grinding gear is simulated and the optimal distribution value is obtained. The research method had some guidance significance on improving the precision of large gear ring forming grinding.
