What are the characteristics of gear hobbing and gear shaving?

1. Gears with different numbers of teeth can be processed with the same tool as long as the module and tooth profile angle are the same. The tooth profile processing methods using the generation principle include hobbing, gear shaping, and shaving. Teeth, honing and grinding, etc. Among them, shaving, honing and grinding are the finishing methods of tooth shape;

2. Gear hobbing is the most productive and widely used tooth shape processing method. A processing method, gear hobbing has good versatility, and can process both cylindrical gears and worm gears;

3. Gear shaping has higher precision than hobbing, and gear hobbing usually has high productivity. The tooth efficiency is also relatively high, but generally lower than hobbing;

4. The gear shaving process is free meshing, and the machine tool does not generate a motion transmission chain, so the machine tool structure is simple and the machine tool adjustment is easy.
