Most of hob design for non-involute gears are nowadays taken by approximation method.For example,the normal sectional profile of hob worm therad is usually regarded approximately as its basic rack profile.Recently, some new methods have been developed in this respect but, perhaps, they appear overelaborate since the principle of spacing engagement is based on. For this reason , the paper offers a new design procedure for hob worm based on the planar engagement principle with the intention of simplific...

本文应用平面啮合原理精确设计各种非渐开线齿轮滚刀的基本蜗杆，提出并应用啮合线的投影原理从工件齿轮端截面的啮合线直接求得刀具蜗杆的端面齿形，而不必求出媒介齿条的齿形，方法很简单，还从啮合线的投影原理简明而形象地证明了一对螺旋齿轮直接啮合过程的啮合线是一条垂直于齿向的平面曲线。

But the involute gear exposes certain own defaults too, such as the external toothing transmission is the engaging transmission of the protruding tooth to the protruding tooth, its contact stress is big,bearing capacity is low etc.

但是渐开线齿轮也暴露出自身一些缺点，如外啮合传动是凸齿对凸齿的啮合传动，其接触应力大，承载能力低等缺点。
