本文在活齿传动啮合原理的基础上,应用运动转化理论,形成活齿传动齿形范成加工原理,并综合出一种附加在滚齿机或插齿机上的内齿轮齿形范成加工装置和范成加工专用机床。它们的共同特点是,可以用简单的回转体刀具加工参数可以任意选择的内齿轮齿形,为普及推广活齿齿轮传动创造了有利条件。 On the basis of the principle of meshing of movable teeth transmission, this paper applies the principle of kinematic transformation to form the machining principle of the gear form of the movable tooth transmission, and synthesizes a gear forming device of the internal gear tooth profile which is attached to the gear hobbing machine or the gear shaper. Into processing machine tools. Their common feature is, you can use a simple rotary tool parameters can be arbitrarily selected internal gear tooth profile, popularization and promotion of live gear transmission has created favorable conditions.
