汽车变速器中的一些齿轮必须通过压装在轴上而不是花键来安装。压合齿轮的扭矩容量将与径向干涉成正比。过多的过盈会增加齿轮的径向变形。本文采用有限元分析方法，从理论和实验两方面对压缩配合及后续转矩能力试验进行了研究。测定了静摩擦系数和动摩擦系数。
Some gears in an automobile transmission have to be mounted by being press-fitted on a shaft instead of splines. The torque capacity of the press-fitted gear will be proportional to the radial interference. The excessive interference, however, will increase the gear radial deformation. In this paper, the press- and shrink-fit and the subsequent torque capacity test were investigated by finite element analysis, theoretically and experimentally. The static and dynamic coefficient of friction were determined.
