P型圆锥凸轮机构的最佳推程、回程运动角及其求解方法

The Solution to Optimum Work Travel and Return Travel Angle of Type P Circular Cone Cam Mechanism

在推程、回程运动角之和Φ０＋Φ０'＝Ｃ（定值）的情况下，必存在某一对推程、回程运动角的最佳分配 ｏｐｔｉｍｕｎΦ０，Φ０'当选用该最佳分配时，直动从动杆圆锥凸轮基圆半径ｒ０取得其取小值ｒ０ｍｉｎ。本文在发现、揭示出上述事实的基础上，研究解决了当选取最佳分配 ｏｐｔｉｍｕｍ Φ０，Φ０'时，按许用压力角条件求解 Ｐ型直动从动杆圆锥凸轮基圆半径最小值ｒ０ｍｉｎ的解析方法。

When the sum of the work travel angle and return travel angle = Constant, there must exist a optimum allot of work travel angle and return travel angle Optimum . When Optimum is adopted, base circle radius r0 of circular cone earn obtain its minimum r0min. On the basis of discovering and revealing the above fact, this paper researches and solves the analytics for r0min of Type P circular cone earn mechanism.
