七十年代末,八十年代初在国外几种刊物上曾先后报导了一种新型减速传动机构—螺环传动机构(TOROIDAL DRIVE),或称超环面传动机构,这种机构有许多优点。本文对它作了概要介绍,并对该机构的关键零件-定子齿槽的成形原理及加工作了叙述,希望它能尽快地在我国得到广泛应用。螺环传动机构图1是螺环传动机构的示意图,旋转运动由圆弧面蜗杆3输入,带动固定于转子4上的行星轮2旋转, In the late 1970s and early 1980s, TOROIDAL DRIVE, or a toroidal drive, has been reported in several foreign publications and has many advantages. This article gives a brief introduction to it, and describes the forming principle and machining of the key part of the organization - stator slot. I hope it can be widely used in our country as soon as possible. Spiral ring drive mechanism Figure 1 is a schematic diagram of the spiroid drive mechanism, the rotary motion input by the worm 3 arc surface, driven by a planetary gear fixed on the rotor 4 rotates 2,
