摘　　要：提出了一种应用Ｂｅｚｉｅｒ曲线设计分度凸轮机构凸轮廓线的方法。就具体的设计要求同采用修正正弦和修正梯形曲线的传统方法进行了对比。Ｂｅｚｉｅｒ曲线对于改善分度凸轮机构的动力学特性和提高定位精度很有利。This paper proposes a way of application of the Bezier curve to design the cam profiles of the indexing cam mechanisms. The effectiveness of the approach is illustrated by comparing the results given by the present method with those given by the modifed sine and modified trapezoidal for the given demands. It is very valuable to enhance the dynamic characters and improve the precison locking of the indexing mechanisms.
