基于瞬心-速度矢量法的辛普森式行星齿轮变速器传动比分析

Analysis of the transmission ratio of Simpson planetary gear transmission based on instantaneous center of rotation-velocity vector method

运用瞬心-速度矢量法绘制3个等速点的线速度矢量,以直观了解行星排中各元件的转动情况,并绘制了辛普森式行星齿轮变速器6种传动方案的速度矢量图。根据相似三角形原理计算了其传动比,验证了该方法的合理性和正确性。

This paper employs the instantaneous center of rotation - velocity vector method to draw the linear velocity vector of 3 isokinetic points, so as to intuitively understand the rotating state of each element of the planet rows. The paper further draws velocity vector diagrams for the 6 kinds of transmission schemes of Simpson planet gear transmission, calculates the transmission ratio according to similar triangle principle, and verifies the rationality and validity of the method.
