摘　　要：凸轮机构的压力角是凸轮机构设计的一个重要参数,决定了凸轮大小和机构强度等诸参数,同时压力角又受其他设计参数尤其是从动件运动规律曲线的影响。在高速凸轮机构中,输入轴速度波动影响从动件的输出响应,文中建立了考虑输入轴速度波动的等效单自由度高速凸轮机构的动力学模型,在此基础上,讨论了输入轴速度波动对凸轮机构压力角的影响。The pressure angle of cam mechanism is an important parameter in its design, which determines many factors as cam size and mechanism strengthen. In addition, the pressure angle is affected by other designing parameters, especially the curve of the follower motion rule. The equivalent single degree of freedom dynamic model of high-speed cam is established while considering the speed fluctuations of input shaft＇s effect on output curve of the follower. Base on the study, the influence of the speed fluctuation of in- put shaft on pressure angle of cam mechanism is discussed.
