齿轮传动压力角凸轮传动压力角在讲授凸轮传动章节中提出：压力角定义为“从动件与凸轮轮廓在某点接触，凸轮对从动件的作用力，其方向为沿接触点的法线方向，我们把这个力的作用线方向与从动件运动方向之间的夹角，叫做凸轮传动在该点的压力角。在这个定义中强调的是把握运动方向和受力方向，在分析时，只要画出接触点从动件的受力方向和运动方向，压力角就能标出（见）所以可以把定义简化为：受力方向与运动方向之间所夹锐角。

　　虽然齿轮传动和凸轮传动都有压力角，然而它们定义的说法却不同。如果我们处理不当，往往造成学生概念模糊，无所适从。能否把二个压力角的定义从认识上统一起来呢，答案是肯定的。通过对的进一步分析，我们不难发现，作过该点的切线的垂线和径向的垂直线所夹锐角，与径向和切向所夹锐角是相等的，而切线的垂线即法线，法线的方向就是受力方向；齿轮运动是圆周运动，径向的垂直线即是该点的运动方向，就是说，齿轮的压力角也可以用过该点的受力方向和运动方向标出（见）至此我们可以将以上两个概念统一定义为：在齿轮和凸轮传动中，受力方向与运动方向所夹锐角为压力角。

　　在讲授齿轮传动实际教学中，一开始就注意引导学生从两个方面来认识压力角的概念，继而在讲授凸轮传动内容时，又对统一的定义进行强化，使学生对压力角概念的认识进一步明确。在具体操作中，我尤其注重启发学生运用所学力学知识对压力角进行分析，使学生能够准确画出各种传动的受力方向和运动方向。
