Reliablity optimal design of ngw type epicyclical gear train 型行星轮系的可靠性优化设计
2.
Reasonable choice of the basic transmission ratio of non - h closed epicyclical gear train 封闭周转轮系基础传动比选择合理性研究
3.
These designing parameters include stiffness of epicyclical bearings , synthetic meshing stiffness of gears , stiffness of supporting bearing of out put shaft , mass of inner rack , meshing angle of gears , distance between inputting shaft and supporting shaft and input speed etc . . according to these analyses , the possible way for improving the dynamic function of three - ring transmission may be put forward 这些设计参数包括：行星轴承刚度、齿轮综合啮合刚度、输出轴支承轴承刚度、内齿板质量、齿轮啮合角、输入轴和支承轴间距及输入转速等，根据这些分析，可以提出改善三环传动动态性能的可能途径。
