摘　　要：本文根据相对运动原理,用瞬心法建立滚子从动件盘形凸轮机构实际轮廓相对于动坐标系的直角标方程,然后采用坐标旋转变换得到其相对于定坐标的直角坐标方程。In this paper, based on relative movement theory and the instantaneous velocity center method, the rectangular coordinate equations relatively with motion coordinate system are obtained. Then the rectangular coordinate equations relatively with fixed coordinate system are obtained by means of coordinate rotary conversion. Thus resultses in a new practical analytical method for designing and manufacturing cam profile.
