利用万能分度头、回转工作台和一些交换齿轮,在立式铣床上用展成原理加工弧齿等高锥齿轮,实践证明,这是一种行之有效的方法。一、工作原理根据刨齿机的工作原理,从锥齿轮的背锥看一个假想平面齿轮与一齿形完整的锥齿轮相啮合的情况,相似于圆柱齿轮与齿条相啮合。如假想平面齿轮 The use of universal indexing head, rotary table and a number of exchange gears, the use of vertical milling machine developed into the principle of tooth profile gear contour bevel gear, the practice has proved that this is an effective method. First, the working principle According to the working principle of planing gear, from the bevel gear back cone to see a hypothetical plane gear with a complete toothed bevel gear meshing situation, similar to the cylindrical gear meshing with the rack. Such as imaginary plane gear
