【Abstract】 A new method to machine cylindrical helical gear with minority number of teeth(2～5) and small diameter on spline miller is described in this paper. The effectiveness of this new method can be improved by 10 times compare to that of traditional machining on gear-hobbing machine.The expressions of undifferentical side set change speed gear about machining cylindrical helical gear with spline miller are given as well as the expressions of side set change speed gear ratio.As a result,the gear precision can be improved by the technology of high speed honing and the degree of roughness is Ra0.4,which attributes to preventing the undesired sound of gearing mesh from being higher than 70 dB.更多还原
