【摘要】 凸轮机构是一种应用很广泛的机构,凸轮轮廓线决定着从动件的运动规律,采用作图方法设计凸轮廓线,精度低, 计算量大。本文介绍在 Pro/E 系统中,利用机构分析功能模块,根据相对运动原理模拟摆动从动件凸轮机构的真实运动规律, 通过对从动件与凸轮接触点的运动轨迹进行分析,自动生成摆动从动件凸轮轮廓曲线的设计方法和过程。更多还原

【Abstract】 Cam mechanism is used very wildly,and the follower’s motion is determined by cam profile,but it is not accurate enough and a mass of calculation is demanded to design a cam profile by plot method.This paper illustrates the process making use of mechanism analysis model to simulate actual motion regulation of the oscillating follower cam mechanism according to the comparative motion theory,and provides the method by researching on the touch point’s motion regulation between follower and cam to automatically generate oscillating follower cam profile based on Pro/E system..更多还原
