摘要
文章根据空间 RSSR 曲柄摇杆机构运动的几何不变量,论述了该机构出现最大压力角的几何特征,探讨了空间RSSR 曲柄摇杆机构最大压力角确定的图解—解析法。
On the basis of the geometrical constant quantities of the motion of spatial RSSR crank-rocher machanism,the geometrical characteristics of the mechanism when the pressure angle is maximum are discussed,and a graphic analysis-synthesis that determines the maximum pressure-angle is presented.
