Study on the Calculation of Parameters and the Machining Method of Profile Curve of Rigid Gear for Harmonic Chain Drive

滚子链谐波传动是一种新型的谐波传动,它克服了谐波齿轮传动的缺点。而其刚轮齿廓的曲线形状是影响传动性能的关键。本文提出了刚轮齿廓曲线方程参数的计算方法,并对齿廓曲线的形成方法进行了分析,并加工出了齿数为31的刚轮。使用结果表明,由公式推导出的刚轮齿廓方程及参数的选择是正确的。

Harmonic chain drive is a new type of harmonic drive, it overcomes some defects of the harmonic gear drive. Profile of rigid gear is the key influence on transmission performance of it. The method for calculating the parameters of profile equation of rigid gear was introduced. The method for forming profile curve was analyzed, on the basis of which the rigid gear whose tooth number is 31 was manufactured. Result shows the deduced profile equation and the choosing of the parameters is correct.
