最小尺寸摆杆平面凸轮机构的新设计方法

A New Method for Designing Minimum Size Oscillating Follower Plane Cam Mechanisms According to Allowable Pressure Angle

关于按许用压力角设计最小尺寸的摆动从动杆平面凸轮机构的课题,至今未获得圆满解决.本文从类角速度图的基本原理出发,推导出限制这种凸轮最小尺寸的界线方程式,从而将图解原理与解析手段有机地结合起来.据此可在电子计算机上图象显示凸轮轴心的容许区域或者直接计算其最小基圆半径和摆杆长度.由于该方法是一种图解解析法,故其具有着图解法形象直观和解析法精确度高的双重优点.文章将这种方法应用于力锁合凸轮、槽道凸轮及共轭凸轮.

Starting from Russian scholar B.T.analogous velocity chart and opening up.a new way,this paper combines organically the graphic method fundamentals with analytic measure,presents a new method for desig- ning minimum size oscillating follower plane cam.mechanisms according to allowable pressure angle.
