摘要

成形法磨齿是对摆线齿轮进行精加工的一种方法。成形砂轮磨齿过程中,当磨削工艺参数选用不合适时,磨削区内产生的瞬时高温将会造成齿面烧伤。为了优化磨削工艺参数,防止齿面烧伤,对齿面温度场分布情况进行数值模拟是非常必要的。运用理论分析计算出磨削过程中的磨削能量及热量分配比,运用有限单元法和计算机仿真软件对摆线轮成形磨削过程中的温度场分布情况进行仿真,得到齿面温度随磨削时间的变化情况以及温度场在齿面的分布情况。通过仿真分析发现,砂轮沿摆线轮轴向方向移动速度vw和沿径向进给磨削深度ap对齿面温度场分布情况有较大影响,整个磨削过程中齿面瞬态温度场最高温度出现在摆线轮齿面尾部靠近齿顶位置,仿真结果与理论分析结果最大误差在10%以内。研究结论对预测齿面温度场分布情况及合理选用磨齿工艺参数有重要的应用价值。

Abstract

Forming grinding process is one of the methods for finishing the cycloidal gear. When the grinding process parameters are not suitable,the instantaneous heat generated in the grinding zone will cause the tooth surface burn. In order to optimize the grinding process parameters and prevent tooth surface burn,it is necessary to simulate the temperature field distribution of tooth surface. Using theoretical analysis to calculate the grinding energy and heat distribution ratio in the process of grinding,using finite element method and the computer simulation software of cycloid gear form grinding temperature field distribution in the process of simulation,the tooth surface temperature with the change of grinding time and temperature field distribution in gear tooth surface are got. Through the simulation analysis,it is found that the velocity vw of the grinding wheel and the radial feed grinding depth ap have a great influence on the distribution of the temperature field of the tooth surface,during the entire grinding process,the maximum temperature of the transient temperature field of the tooth surface appears near the tip of the tooth surface of the cycloid gear. And the maximum error of the simulation results and theoretical analysis is within 10%,which is of great value for the prediction of the distribution of the temperature field of the tooth surface and the reasonable selection of the grinding process parameters.
