Abstract

See full text

A method for producing a gearwheel having an axis of rotation and a tooth system. The teeth have an axial undercut on the tooth flank sides thereof. A blank is provided having a tooth system, wherein the teeth of the tooth system are provided so as to be tilted relative to the axis of rotation such that a forming tool can advance substantially fully into the tooth flank sides of the teeth through an axial linear motion along the axis of rotation. A preliminary form of the at least one axial undercut can be provided on the tooth flank sides. A first axial forming operation is performed in the form of a first axial forging blow via which a preliminary form of the at least one axial undercut is introduced on the tooth flank sides or an already existing preliminary form of an axial undercut is sized for accuracy.
