摘要

介绍了轴套式花键的功能、结构及材料选择，并对花键的渐开线齿进行了强度的理论计算。过盈量的大小不仅决定了轴套式花键能否可靠传递轮轴间的扭矩，而且决定了轴套与车轴过盈配合面间的应力大小，对过盈量进行了理论和有限元计算，同时还对轴套式花键进行了疲劳强度校核。计算和分析表明：选择轴套式花键来传递轮轴间的扭矩不仅大大降低了对车轴材料的性能要求，而且是切实可行的。

Abstract

The function, structure and material selection of axle sleeve type spline were introduced, and the strength calculation of involute tooth of spline was carried out. The size of the interference amount not only determined whether the axle sleeve type spline could reliably transmit the torque between the axle and wheel, but also determined the stress between the interference fit of the axle sleeve and the axle. Theoretical and finite element calculation of interference was put forward, at the same time, the fatigue strength of axle sleeve type spline was checked. The calculation and analysis showed that choosing the axle sleeve type spline to transfer the torque between the axle and wheel not only greatly reduced the performance requirements of axle materials, but also was feasible.
