摘　　要：利用简单行星排传动比计算式,导出行星排基本运动学关系式。对某型号坦克三自由度行星齿轮变速箱工作原理进行分析,揭示出三自由度行星齿轮变速箱可通过操纵元件的不同结合,实现不同的动力输出,通过利用行星排基本运动学关系式和行星齿轮变速箱中离合器的两两不同结合这个约束条件,对有关的行星排基本运动学关系式进行简化,从而比较容易地计算出七个前进挡和一个倒挡的传动比。The basic kinematics relation for planetary gear train was derived by using simple planetary transmission ratio calculation formula.The three degrees of freedom of planetary gear transmission working principle of a type tank was analyzed,which can complete different power outputs by manipulating different combination of components.By using basic kinematics relation and two different clutch combination of constraint conditions,basic kinematics relation for planetary gear train further simplified,thus more easily calculate the seven forward gears and one reverse gear transmission ratio.
