【Abstract】 In this paper, the mechanism of the profile convex has been studied. It indjcated that the enagement of out centreline in shaving has a deep, influence to the error of the profile. Td improve the overlap coefficient of shaving cutter and shaved gear is an important way so as to overcome the profile convex. On the base,it also put forward the suggestion to correct the convex angle size of preshaving hob cutter.更多还原
