Relief grinding of planar double-enveloping worm gear

24/08/2016  A mathematic model is built for the relief grinding of the hob. A series of related data of the four motion parameters when grinding different points of the land edges of the different hob teeth are solved out, and the relief surfaces of different hob teeth can be ground continuously by using the data. The method is verified by using software VERICUT. Furthermore, a worm gear hob is relief ...
