圆柱蜗杆传动在机械中得到广泛应用。但由于蜗轮、蜗杆种类繁多,一般工厂不可能配备有各种规格的专用蜗轮滚刀,这就给单件和小批生产带来了困难。通常解决的方法是用飞刀切制蜗轮,但生产率低,精度差,影响使用寿命。 Cylindrical worm drive is widely used in machinery. However, due to the wide range of worm gears and worms, it is impossible for the general factory to be equipped with a variety of special worm gear hobs, which brings difficulty to single-piece and small-batch production. The usual solution is to cut the worm gear with a flying knife, but the productivity is low, the accuracy is poor, and the service life is affected.
