摘　　要：讨论了平顶从动件盘状凸轮机构的运动特点、润滑状态、强度及在液体动力润滑和边界摩擦条件下两种失效形式、基本计算.并指出点蚀和磨损首先在凸轮轮廓曲率半径最小的顶端发生.This study involves several isues of flat-topped servounits in a plate-shaped cam mechanism. These include the motional characteristics, lubrication conditions and strength constraints. Furthermore, two deficiency cases, together with theoretical calculations, are presented under hydrodynamical and boundary-frictional conditions. Thereafter,it is found that corrosions and abrasions first occur at the cum top with minimal curvature radius.
