用展成法铣蜗轮,通常是在滚齿机上进行的。但是,当某些工厂里如果没有滚齿机和专用的蜗轮滚刀时,要想用展成法加工蜗轮,就会感到有一定困难。在这个问题上,东北机器制造厂在今年的设备维修学术会议上,给我们提供了在万能铣床上,用梯形圆片铣刀滚切蜗轮的经验。实践证明,用这种方法铣出来的蜗轮,精度可以达到8级,光洁度为▽▽6,啮合的接触面沿齿高方向为60%,沿齿长方向为50%。为了把这种铣蜗轮的方法向大家推广, Worm milling with the exhibition, usually hobbing machine. However, when there is no hobbing machine and a special worm gear hob in some factories, there is some difficulty in machining the worm gear by the exhibition method. In this issue, the Northeastern Machinery Manufacturing Plant in this year’s equipment maintenance conference, to provide us with a universal milling machine, with a trapezoidal disc cutter rolling hobbing experience. Practice has proved that, with this method of milling the worm wheel, the accuracy can reach 8, the finish is ▽ ▽ 6, the mating contact surface along the tooth height direction of 60% along the tooth length direction of 50%. In order to promote the method of milling worm gear to everyone,
