摘　　要：建立了星型齿轮传动动力学系统基本构件浮动位移量分析模型;计算了系统基本浮动构件浮动位移量;分析了系统主要设计参数对各构件浮动位移量的影响,对星型齿轮传动系统浮动机构的设计提供依据。分析表明,中心轮的浮动位移量不随系统输入功率的变化而变化,随系统转速的增大而增大;中心轮的浮动位移量随系统星轮个数的增加而增大,随系统构件误差值的增大而增大,各构件的误差值对中心轮的浮动位移量的影响有累加作用;中心轮的浮动位移量随其齿轮的质量及转动惯量的增大而增加。A floating displacement analysis model of a two-stage star gear train＇s dynamic system was established. The floating displacement of its basic parts was calculated. The influence of its main design parameters on the floating displacement is analyzed. These provide theoretical background for the design of the basic floating parts of the star gear train. The floating displacement of center gears does not change with the power change of the train, and increases with the increase of the rotational speed of the train. The floating displacement of center gears increases with the increase of the number of the star gears and with the increase of the errors. The errors have accumulative effects on the floating displacement of center gears and the floating displacement gears increase with the increase of the mass and moment of inertia of the gears.
