摘要
基于蜗杆砂轮磨削面齿轮原理和空间曲面理论,推导了面齿轮齿面磨削点处主曲率和主方向计算公式;基于瞬时椭圆接触理论和磨削热理论,建立了面齿轮磨削温度场理论公式;基于ANASY建立面齿轮磨削温度场有限元模型,完成了磨削温度场有限元仿真;设计完成了磨削温度场实验,验证了有限元法的正确性;基于正交试验法,研究了磨削工艺参数对齿面温度分布的影响规律。
The principal directions and corresponding curvatures at grinding point on face gear tooth sur face are derived according to meshing theory and differential geometry theory. Based on instantaneous elliptic contact theory and grinding heat theory, the theoretical formula of grinding temperature field of face gear is es tablished. The finite element model of grinding temperature field of face gear is established based on ANASY, and the finite element simulation of grinding temperature field is completed. The experiment of grinding tem perature field is designed and the correctness of finite element method is verified. Based on orthogonal experi ment, the influence of grinding process parameters on tooth surface temperature distribution is studied.
