In the gear rolling, the finished profile may slightly incline toward the direction of the rolling force. Probable error for the profile of rolled surfaces obviously results from the tooth inclination. In this paper, the gear blank, which was previously hobbed as m=1.5,α_0=25°, Z=27,and whole depth=1.8m is rolled by the free driving both rack dies. Then, the profile of the driven side and that of the follower side of the blank are modificated, respectively by a preferable involute apart to the direction of the opposite rolling force. By the investigation of those finished rolling conditions, the desirable modification of the tooth profiles were decided, and the rolled involute profiles were improved.
