留磨花键滚刀的齿形设计

The Tooth Profile Design of Spline Hobs with Tooth Side and Bottom Grinding Tolerances

本文对键侧和键底留有磨削余量的矩形花键轴滚刀提出了用直线刃代替常用的曲线刃的方法，这可简化滚刀的设计和制造，改善滚刀侧刃的切削性能，并使滚出的花键轴键侧截形呈鼓形曲线，有利于提高键侧的磨削质量和砂轮的耐用度．

In the peper,a method is introduced in the designing of spline hoal with tooth side and bottom grinding tolerances, in which Straignt-line cutting edgeS are used to replace the traditional curved edges. By using the method, the designing and manufacturing of hobbing cutters Can be simplied, the cutting properties of edges improved, the sections of tooth sides of spline shafts made curved outWard. As a result, the grinding quality of spline tooth Sides and the durability of grinding wheels are ameliorated.
