补充资料:机械原理:压力角
压力角
在平面连杆机构中不计摩擦和构件的惯性的情况下﹐机构运动时从动件所受的驱动力的方向线与该力作用点的速度方向线之间的夹角。在曲柄摇杆机构中(图1 曲柄摇杆机构的压力角 )﹐主动件通过连杆作用在摇杆上的力P 沿BC 方向﹐力作用点C 的速度的方向垂直CD ﹐这两方向线所夹的角 为压力角。压力角越大﹐P 在方向能作功的有效分力就越小﹐传动越困难。压力角的餘角a 称为传动角。机构的压力角或传动角是评价机构动力学指标之一﹐设计机构时应限制其最大压力角或最小传动角。对於齿轮传动 (图2 轮齿某嚙合位置的压力角 )﹐压力角 a也是从动轮齿上所受驱动力P 的方向线与P 力作用点Vc的速度方向线之间的夹角﹐压力角a的大小随著轮齿嚙合位置的不同而变化。
