具有圆柱内齿轮的非圆行星齿轮机构节曲线的设计

Pitch Curve Design of Non-circular Planetary Gear Mechanism with Cylindrical Internal Gear--Calculation of Pitch Curve in Non-circular Gear Pair

根据齿轮啮合理论 ,提出一种具有圆柱内齿轮的非圆行星齿轮机构的节曲线设计方法。在该行星齿轮机构中 ,行星齿轮与一个中心齿轮皆为非圆外齿轮 ,而另一个中心齿轮为圆柱内齿轮 ,且系杆的长度是变化的。这种行星齿轮机构的加工简单 ,装配方便 ,具有应用前景。

A design method of pitch-curve of non-circular planetary gear mechanism with cylindrical internal gear is presented according to gear engagement theory. In this planetary gear mechanism,the planetary gear and one of the center gears are non-circular external gear while another center gear is cylindrical internal gear, and the length of planet carrier is variable. This planetary gear mechanism will have good future because of its simple manufacture and convenient assembly.
