中文摘要：

弧齿锥齿轮齿面残余应力是磨削条件下各种因素综合作用而产生的。建立了影响磨削残余应力的磨削基本参数、磨削热和磨削力的数学模型。在有限元3D单齿模型基础上,进行了弧齿锥齿轮磨削残余应力的有限元仿真与分析,并试验验证了此方法是可行的。结果表明：残余压应力呈现在弧齿锥齿轮齿面上,而残余拉应力在齿内;磨削残余应力与磨削深度、砂轮速度、展成速度、磨削液有关;磨削残余应力的降低能有效地预防磨削裂纹。

英文摘要：

The residual stress of spiral bevel gear on the tooth surface is produce by the comprehensive effect of various factors of grinding conditions.The mathematical model of the grinding basic parameters of the effects on grinding residual stress,grinding heat and grinding force.Based on the finite element 3D model of single tooth,the finite element simulation and analysis of residual stress of spiral bevel gear grinding,and the test shows this method is feasible.The results show the residual stress present in the spiral bevel gear tooth surface,while the residual tensile stress in the tooth,the grinding residual stress is connected with grinding depth,wheel speed,extended speed and grinding fluid.The reducing of grinding residual stress can effectively prevent grinding cracks.
