Relief grinding of planar double-enveloping worm gear

2016-8-24  Compared with single-enveloping worm gearing, double-enveloping worm gearing can provide the same load capacity with a more compact volume and a higher efficiency. However, that the relief grinding of its hob can not be finished automatically till now limits its applications because all of the cutting edges on the hob have different shapes and spiral angles. In this paper, a pioneering method ...
