摘要
通过对空间凸轮机构圆锥滚子摆动从动件圆锥凸轮工作过程的分析,指出了常用的平面展开及偏距加工法存在误差。将圆锥滚子摆动从动件圆锥凸轮机构的运动过程进行分解,提出从动件运动轨迹的3-D展开法,并在此基础上提出了一套圆锥滚子摆动从动件圆锥凸轮非等径加工的"仿摆线"加工法,有效地解决了圆锥滚子摆动从动件圆锥凸轮非等径加工的难题。
This paper focuses on the analysis of running conditions and machining processes of conical cam with oscillating follower.Common errors were pointed out in the biased distance cutting.By analyzing the motion of oscillating tapered roller follower of conical cam,a new ＂3-D curve expansion＂ model of conical cam was presented trough-outline.Based on this model,a machining method for trochoidal milling was proposed with non-equalization diameter cutter.This new method is a creative and effective way for non-equalization diameter machining for conical cam with oscillating tapered roller follower.
