前言对于设计滚子从动件盘形凸轮实际廓线,一般用解析法是先求凸轮理论廓线,然后通过理论廓线再求实际廓线。本文是将凸轮和从动件两者的接触传动视为两个构件的啮合运动,其啮合点(接触点)的轨迹称为啮合线。利用啮合线是凸轮转角、从动件运动规律和机构尺寸的函数关系,建立啮合线的坐标表示式,然后利用坐标系旋转法直接 Preface For the design of roller follower disc cam actual profile, the general analytical method is to seek the cam theoretical profile, and then through the theoretical profile and then seek the actual profile. In this paper, the contact transmission between the cam and the follower is regarded as the meshing movement of the two components. The trajectory of the meshing point (contact point) is called the meshing line. The use of meshing line is the angle of the cam, follower movement and the size of the mechanism as a function of the relationship between the establishment of meshing coordinate representation, and then use the coordinate system rotation method directly
