Abstract
Pitch generation method for the production of bevel gears and mainly for the rough hobbing of pinions, with working of the pinion blank during generating of the tooth profiles, using a single cutter head for working both flanks of each tooth space. The generating speeds and ratio of roll of the cutter head, as well as the profile angle of the cutters are kept uniform. The desired, curved outlines of the tooth flanks, establishing a tapering tooth space, are generated by a simple mechanism which generates the proper motions of the gear cutters. For this purpose the cutter head is pivoted, opposite the workpiece or gear blank, in a drum, for several swiveling motions.
