渐开线28°压力角直齿轮应力分析

Stress analysis for involute spur gear with 28 degree pressure angle

基于解析和数值计算相结合的方法,在啮合区施加近似椭圆柱分布压力和相应的摩 擦力,获得28°压力角直齿轮的最大接触应力和第4强度相当应力,从而为齿轮设计提供有益的参 考。

Based on the method of combining theoretical calculation with numerical computation, applied approximate ellipsoidal pressure and corresponding friction on the engaging involute surface, the maximum contact stress and mises stress of the straight-tooth spur gear with 28 degree pressure angle are investigated in this paper,thus providing useful reference with designing gear.
