Abstract
In order to improve productivity and product quality, reduce product cost, over the years, many factories producing gear are bevel gears for a new method, which is using gear chamfering hob, hobbing on ordinary chamfer. This method is suited for medium and small batch production, tool life is long, stable machining quality. Process, the hob to do continuous cutting movement, no air travel, but also in the hob at the same time to participate in multi-tooth cutting blade, processing efficiency. In this thesis, the principle of meshing gears and the rack, put forward chamfer hob design principle and calculation method, the basic worm on the hob and the chamfer chamfer hob blade shape analysis of the research, design the two inverted Corner hob, which one is the smaller half of the amount of gear chamfering chamfering hob, the other to a large amount of shift gear chamfering chamfering hob.
Key words: Rack gear,Chamfering amount,Basic Worm
