When hypoid gears are used in automobile rear axles, the gear axes are relatively displaced. The relative displacement of gear axes causes gear noise. In order to reduce gear noise, it is necessary to modify the tooth surfaces of the gears. In this paper, a method for cutting hypoid gears with modified tooth surfaces is proposed. In this method, the nongenerated ring gear is cut by a cutter in which each cutting edge is modified from the usual straight line to a circular arc with a large radius of curvature and the pinion is generated by a cutter with straight cutting edges as usual. Although an irregular tooth surface which does not mesh with the mating surface is apt to appear on the pinion tooth flank during manufacturing, with this method, the surface does not appear. The main procedure of this method is the determination of the machine settings for the Gleason hypoid generator. In order to confirm the validity of the method, a pair of hypoid gears was designed and manufactured using this method. As a result, the tooth bearing was acceptable and the appearance of the irregular tooth surface could be avoided.
