摘　　要：压力角是影响空间分度机构受力情况和工作效率的一个重要参数,以圆柱分度凸轮为例,运用M atlab三维图形方式表现压力角α与θ及l三者之间的关系,便于更加直观地看清压力角α的变化规律。该方法适用于所有空间凸轮机构的压力角分析。Pressure angle is an important parameter that can affect spatial indexing mechanisms＇ stress and work efficiency. In this paper, the ealculation formula of pressure angle is given by taking an cylinder indexing cam as an example, and the relation between a,8 and l with 3 dimensional graphics that generated in Matlab is illustrated. The method can benefit us to know the law of a hanging of the pressure angle and can be used for analysis of spatial indexing cams＇pressure angle.
