| 摘 要： | 本文从合成运动的观点出发,通过对两接触机构的接触点的讨论,直接给出了该机构接触点相对运动轨迹的瞬时曲率半径的一般表达式。同时,也给出了常见机构接触点相对运动轨迹曲率半径的具体公式。从而不必研究接触点相对运动的轨迹便可直接得到其曲率半径。

| Abstract: | From the viewpoint of compound motion, a common expression for finding the instantaneous curvature radii of relative motion path of contact points is directly derived by studying the contact points of two contact mechanisms. At the same time, a concrete formula for finding the cur- vature vadii of relative motion path of common mechanism is presented. thus, the curvature radii can be directly obtained unnecessarily to study the relative motion path of contact points. |
