为了解决采用无差动装置滚齿机加工小螺旋角齿轮,加工原理、公式推导过程欠缺的问题,详细演示了其加工参数的计算推导过程;通过实例说明采用无差动装置滚齿机加工螺旋齿轮参数的计算及挂轮定数的确定。指出:当齿轮螺旋角太小、差动挂轮速比大于1∶6时,或螺旋齿数为质数齿、齿数大于100齿时,都可采用无差动挂轮滚齿,利用推导公式进行挂轮调整,加工效果良好。

In order to solve the problems with the production of gear with small spiral angle using the non-differential hobbing machine, the processing principle and formula derivation, a de- tailed presentation is given of the processing parameters of the calculation process. The example shows how to make determination of gear change number using non-differential hobbing for spiral gears. It is pointed out that when the gear spiral angle is too small and the differential hanging wheel speed ratio is greater than 1 ： 6,or helical teeth number is of prime number and the teeth number is greater than 100 teeth,non-differential gear hobbing is employed, using the derived formula regulating the hanging round with good processing effect.
