卫星齿轮传动的单元分析法

目前，卫星齿轮传动的功率流分析、传动比和啮合效率计算，既难又繁。在此，首先将卫星齿轮传动分解成几个基本周转轮系单元，并绘出离散图，然后按离散图逐个对这些单元进行运动分析和功率流分析，最后对传动比法进行了改进。这种新的分析法简明易懂，深入浅出地解决了以上难题。

Unit analysis method of satellite gear drive

At present, the analysis of power-flow of satellite gear drive and calculations on its transmission ratio and meshing efficiency are both difficult and complicated. At here, firstly let the satellite gear drive be decomposed into several elementary epicyclic train units and the discrete graphs be plotted, and then carrying out motion analysis and power-flow analysis one by one upon these units in accordance with discrete graphs, finally, an improvement is conducted as well on the method of transmission ratio. This new analytic method resolved the above difficult problem in simple terms and a brief easily understanding way.
