摘要

针对非圆齿轮无级变速传动技术中非圆齿轮的设计,提出了一种设计非圆齿轮传动的新方法。运用该方法解决了在整个周期内两段非圆齿轮传动比函数曲线在连接点处一阶光滑连续的问题,消除了非圆齿轮节曲线上的尖点,保证了传动的平稳性。通过实例,运用该方法重新确定了应用于无级变速传动中的非圆齿轮的传动比函数,设计出了节曲线光滑连续的非圆齿轮。该方法还可以适用于一般的非圆齿轮的设计。

Abstract

A new design approach of non- circular gear is proposed in order to solve the design problems of non- circular gear on continuously variable transmission. Using this approach,the transmission ratio function of non- circular gears composed by two functions in the entire cycle is smooth and continuous at the connection points,and then the cusps of the non- circular gear pitch curve are eliminated in order to ensure the smooth transmission. Finally,the example is given,the transmission ratio function of non- circular gears on continuously variable transmission is redefined and the non- circular gears of the smooth and continuous pitch curve is redesigned by using the approach. This approach can also be applied to the general design of non- circular gear.
