摘　　要：2K H型差动轮系是构成行星变速器的核心 ,本文提出一种新的分析方法。用这种基本周转轮系 3个基本构件之间的传动比关系式推导行星变速器各挡位的传动比计算公式 ,用基本构件之间的功率比关系式分析变速器中各基本构件的输入输出特征 ,绘出功率流向图并确定啮合功率的流向 ,最后用传动比法导出啮合效率计算公式。A new analytic method for planet gear transmission is presented. Calculation formulas of transmission ratio for the planet gear transmission are deduced by the relation of transmission ratio of three basic links of this kind of elementary epicyclic gear train. The property of input-output of the basic links is analyzed and the power flow plans are depicted and the direction of meshing power is determined for the planet gear transmission by the relation of power ratio of the basic links. Finally, the calculation formulas of meshing efficiency are set up according to the drive ratio method.
