摘要

通过绘制CR-CR式行星齿轮机构中齿圈、行星架和太阳轮的线速度矢量图,直观呈现行星齿轮机构中各元件的转动方向和速度大小。基于得到的线速度矢量图,利用几何法计算典型传动方案的传动比,与解析法计算出来的传动比完全一致,进而验证了利用线速度矢量法对CR-CR式行星齿轮机构的传动方案进行分析的正确性和可行性。

Abstract

The rotation direction and speed of each element in the planetary gear mechanism can be directly shown by drawing the linear velocity vector diagram of the gear ring,planet carrier and sun wheel in the CR-CR planetary gear mechanism. The transmission ratio of typical transmission scheme is calculated by geometric method based on the obtained line speed vector diagram,which is exactly the same with the transmission ratio calculated by analytical method. The correctness and feasibility of analyzing the transmission scheme of CR-CR planetary gear mechanism by line velocity vector method is verified.
