基于等磨损的新型两齿差外啮合行星传动变位系数选取

基于两齿差外啮合行星传动的结构特点及失效形式,提出一种防止结构失效的齿轮参数优化设计方法,通过优化算法得到了各齿轮副间的变位系数合理分配,使得主、从动齿轮与行星轮啮合时的滑动系数趋于相等,减少各齿轮副啮合时的相对滑动,从而大大提高了这种新型结构的寿命。

Modification Coefficient Choose of the Outer Mesh and "Two Teeth Difference" Gear Planetary Transmission Based on the Even Equal Wear

Based on the structure and failure features of a new type of outer mesh and "two teeth difference" planetary gear transmission, a optimize method for the gear's parameters is pointed out avoid of structure failure. The modification coefficients of the gear pairs are obtained through optimize program, so the sliding coefficient for the active gear, passive gear and planetary gear approach to even. The relative slide between gears is reduced, and the working life of the structure is increased greatly.
