成形法加工螺旋锥齿轮铣削力模型

摘要

根据成形法加工螺旋锥齿轮的几何理论,推导了任意时刻切削厚度和切削宽度的计算公式,建立了成形法加工螺旋锥齿轮大轮的动态铣削力模型,通过单因素实验标定了铣削力系数,编写了成形法加工螺旋锥齿轮大轮动态铣削力仿真程序.为验证动态铣削力模型的有效性,设计了实验装置.铣削力计算结果和实验结果的误差不超过±15％,证明了铣削力模型的正确性.%Based on the geometrical theory of the form milling the spiral taper gear, the computational formula of the cutting thickness and cutting width in every time was deduced. The milling force model for form milling the spiral taper gear was presented. The milling force factors were calibrated via single factor experimentations and the form milling force simulation programs were prepared. Experimental installations were designed to validate the availability of the milling force model. Comparison between the computational results and experimental observations confirmed the validity deviation of the proposed model was within ± 15% .
