摘　　要：通过分析摆动从动件圆柱凸轮加工过程和工作状况,指出了常用的圆柱凸轮凹槽轮廓线平面展开法在设计和加工中存在的误差,提出了按圆柱曲面展开进行圆柱凸轮凹槽轮廓线设计的3D曲线展开法,并在此基础上运用坐标变换,对摆动从动件的不同运动关系表达式制定了一套有效的设计和加工方案。Based on the research and analysis of running condition and manufacture process of cylindrical cam with oscillating follower, as the widely used plane expansion method for cylindrical cams trough-outline in the design and manufacture processes, the inaccuracy was pointed out. To improve the current plane expansion method, a new system named “3D curve expansion” was proposed for cylindrical cam trough-outline design. This system takes advantage of the expansion on cylindrical cursive surface and coordinates transformation of motion curves based on the movement of oscillating follower. By applying this “3D curve expansion” system to the cylindrical cam design and manufacturing, a set of effective methodology was established.
