二十四、具有精确谷部圆弧的三角形花键滚刀代圆弧齿形反共轭误差控制设计法对于一般三角形花键,只基于花键齿形在有效齿侧高度内的精度保证.而对其根部过渡线的几何形状不作严格要求(参看第二十一、二十二节)。但在承受反复载荷的花键结合中.为了提高花键的疲劳强度。有时需要对花键齿谷表面施于冷滚压。要使表面 Twenty-four, with a precise valley arc triangular spline hob generation arcuate anti-conjugate error control design method for the general triangle spline, spline tooth profile based only on the effective tooth side height accuracy assurance. There is no strict requirement on the geometry of the root transitional lines (see sects. XXI and XXII). But in the repeated load spline combination.In order to improve the spline fatigue strength. Sometimes it is necessary to apply cold rolling to the surface of spline teeth valley. To make the surface
