摘　　要：建立星型齿轮传动静力学系统基本浮动构件浮动位移分析的弹簧-质量模型;采用静力学分析的方法,考虑系统的误差、工况条件、构件的弹性变形等条件对系统浮动位移的影响;计算系统基本浮动构件浮动位移;分析系统主要设计参数对各构件浮动位移的影响,为星型齿轮传动系统浮动机构的设计提供依据。结果表明:中心轮的浮动位移随系统输入功率增大而增大,随系统转速增大而减小;中心轮的浮动位移随系统星轮个数的增加而减小,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浮动位移的影响有累加作用。系统的工况条件、构件的弹性变形等方面均影响系统的浮动位移,在实际计算中要予以考虑。A floating displacement static analysis model of basic floating part of 2-stage star gear train was presented. The influence of the system errors, work conditions and elastic distortion of the components on floating displacement was considered in static analysis. Floating displacement of basic parts was calculated. The influence of the main designed parameters on floating displace- ment was analyzed. The reference was supplied for designing the basic floating part of star gear train. The results show that the floating displacements of center gears change largely with the increase of the system power while change slightly with the increase of the system rotate speed. The floating displacements of center gears decrease with the increase of the number of the star gear and increase with the increase of the system errors. The component errors have cumulative influence upon floating displacement. The system errors, work conditions and elastic distortion of the components all have certain influence upon floating displacement, so they have to be considered when floating displacement is calculated.
