基于实际数控加工弧齿锥齿轮刀盘中心位置分析

Analysis of the cutter-head center's location based on actual NC machining of spiral bevel gears

以弧齿锥齿轮切齿加工原理为基础,建立了产形轮与被加工齿轮切齿时的啮合方程,根据弧齿锥齿轮大小轮的加工方法,完成机床参数的调整,并根据啮合方程式确定展成切削时刀盘中心起始位置和终止位置。最后通过实例验证了这种方法的正确性。

Using the gear cutting theory of spiral bevel gears ,we establish the mesh equation of between octoid crown gear and workpiece gear. According to the machining methods of spiral bevel gears ,we adjust the parameters of machine tools and confirm the start location and end location of the middle of cutter according to the equation of action. The correctness of the method is verified by an example presented at the end of it.
