一类双齿轮曲柄机构传动特性的研究

A Study on the Transmissive Characteristics of a Type of Two-Gear Crank Mechanism

通过对一类双齿轮曲柄机构传动函数的研究，提出了一种输入、输出轴作同轴线、转向相反、恒速比传动的双齿轮平行四边形机构；提出了输出轴作瞬时中间停歇、部分逆转或非匀速单向转动的Ｚｚ齿轮曲柄机构的设计方法。

Through studying the transmissiyefunctions of a type of two-gear crank mecha,nism, this paper presents a kind of two geared parallelogram mechanism which inputand output axes are coaxal,which rotativedirections are opposite and the angular speedratio is a constant;and presents the designmethods for the two -gear crank mechanismwith an instantaneous middle dwell or reversein sectional rotative angle or one - way rotanon at nonuniform speed.
