摘　　要：凸轮与从动件之间存在严重的滑动磨损,导致凸轮的传动精度降低,影响使用寿命。文中探讨应用弹流润滑理论对凸轮基本尺寸进行设计的方法,改善凸轮与从动件间的润滑条件,减少凸轮的过度磨损。There exists serious sliding abrasion between cam and follower, thus leads to a reduction on the transmission precision of cam and affected the service life. The method for carrying out design on the basic dimensions of cam by applying the elastohydrodynamic lubrication theory has been discussed in this paper thus improved the lubrication condition between cam and follower and reduced the excessive abrasion of cam.
