在车床上用蜗轮滚刀单个滚切蜗轮,这种方法由于蜗轮滚刀在切削过程中受较大径向力,是不均匀切削,不仅精度光洁度不易达到要求,而且生产率较低。为了克服以上缺点,我们在一九七五年八月份的生产高潮中,设计制造并使用了“小模数蜗轮组合加工装置”。此装置是用蜗轮蜗杆啮合的原理来滚切蜗轮。此装置能同时加工蜗轮的数量,取决于蜗轮最小包角及结构上的可能。这种滚切是通过下图 In the lathe with a hob hob hob single hobbing worm wheel, this method is due to the worm wheel cutter in the cutting process by a large radial force, is uneven cutting, not only precision finish difficult to meet the requirements, and lower productivity. In order to overcome the above shortcomings, we designed and manufactured the “Small Modular Worm Gear Combine” at the peak of production in August 1975. This device is based on the principle of worm gear to hobbing worm gear. This device can simultaneously process the number of worm wheels, depending on the minimum angle and the structural possibilities of the worm gear. This hobbing is through the figure below
