The interference between the tooth surface of the worm and the grinding wheel will occur under certain conditions of grinding wheel diameter and setting parameters, which will lead to the overcut of the tooth surface.

在一定的砂轮直径及安装参数下磨齿时砂轮和蜗杆的齿面将产生干涉，致使蜗杆齿面发生过切。

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。

The helix angle on the worm is generally quite large, and that on the gear very small.

蜗杆上的齿斜角度通常很大，而蜗轮上的则极小，因此习惯常规定蜗杆的导角，那就是蜗杆齿斜角的余角；也规定了蜗轮上的齿斜角，该两角之和就等于90度的轴线交角。

A new-type bike features that its pedal crank has an arc rack bar acting on the ratchet gear in single direction and in turn driving the drive chain wheel, a reset unit composed of crank mechanism is used to make left and right pedal cranks be pedaled alternatively, and its front movable saddle plate is connected via connecting rod to pedal crank for making rider comfortable. Its advantages are high drive performance and efficiency and saving labour.

一种新式自行车，其最大特点是蹬踏杆上含有一弧形齿条，由该弧形齿条上的轮齿作用于具有单向离合的棘齿轮，从而带动主动链轮转动，由曲柄机构组成的复位器使左右蹬踏杆能够交替连续踩踏以驱动自行车行驶，前活动座板与蹬踏杆由连杆相连结，从而实现同步摆动给以乘骑者踩踏感到舒适，该发明具有传动性能好，效率高，力损耗小等优点。
