摘　　要：依据弹性流体动力润滑理论研究发动机凸轮与其从动件间的润滑特性。将凸轮型线的优化设计和凸轮与从动件间的磨损情况结合起来，采用润滑特性数Ns、流体动力润滑评定特性数Nr和无量纲润滑特性数Nz，对CA488型发动机的凸轮润滑特性进行了分析。Lubricating characteristic of engine cam and its follower is studied based on thetheory of elastic hydrodynamic lubrication. The lubricating characteristic of model CA488 enginecam has been so analysed that optimum design of cam contour curve is considened in combinationwith wear condition between carn and follower,and lubricating characteristic number Ns,character-istic number for evaluating hydrodynamic 1ubrication N. and dimensionless lubricating characteris-tic number Nz are adopted.
