一、引言在机械设计中,常遇到要求从动件的位移、速度、加速度按指定的规律变化的问题,这时应用凸轮机构可以使设计简便、机构紧凑、运动精度高、动力性能好。特别是从动件的运动规律复杂时,更宜采用凸轮机构。 I. INTRODUCTION In mechanical design, the problem that the displacement, speed and acceleration of follower are often required to change according to the specified rule is often encountered. In this case, the application of cam mechanism can make the design simple, the mechanism is compact, the movement precision is high, and the power performance is good. In particular, follow-up movement of complex rules, the more appropriate use of cam agencies.
