Some reports have been given on hobbing internal gears. But in all cases, the tooth generation with the hob has not been put in practical use because the problems lay in manufacturing of the hob. So the authors have made research on Spherical hob to solve the problems and succeeded in tooth generation. In this paper, we explain the method of spherical hob manufacturing and hobbing equipment remodeled for internal gear and describe the quality of internal gears. As the results of test hobbing, total profile error was 12μm. The profile did not change even if the hob was shifted or the setting angle of the hob was changed. As for the pitch error, maximum circular pitch individual error was 5 μm and maximum cumulative pitch error was 19 μm. These values mean that the hobbed internal gear has the highest accuracy.
