非圆链轮的节曲线设计

在非圆链传动的设计中，一个关键问题就是非圆链轮节曲线的设计。本文根据包络法，研究了非圆链轮节曲线的设计原理；按非圆链传动实现功能的不同，重点研究了非圆链传动作为函数发生机构时其节曲线的计算方法并给出了具体的计算公式。

Design of Pitch Line for Noncircular Chain Wheel

In the design of noncircular chain drive , the key problem is the design of pitch line of noncircular chain wheel.In this paper,the design principle for the pitch line of noncircular chain wheel is researched according to the principle of envelope.Based on taking the noncircular chain drive as a function generator,the calculation methhod of pitch line is mainly studied , and the calculation equation and a practical example are given at last.
