The invention makes available a method for the production of gear wheels, with which it is possible to produce gear wheels having double-helical teeth, in particularly efficient manner. For this purpose, in the case of the method according to the invention for chipping production of a gear wheel, which is provided with double-helical teeth, in which the teeth of the one gear half are configured to run counter to the teeth of the other gear half, in rising manner, wherein the gear halves are arranged offset from one another by an angle amount with reference to the axis of rotation of the gear wheel, a gear wheel blank is made available, on which the teeth provided on the gear wheel are produced by means of hobbing, using a hobbing wheel, which, during hobbing machining of the teeth, in each instance, of one of the gear halves, reaches all the way into the adjacent tooth gaps of the other gear half, in each instance.

A herringbone gear includes a cylindrical body having a circumferential face having a width. A first helical gear tooth on the circumferential face has a first configuration, a second helical gear tooth on the circumferential face has a second configuration, and a transition on the circumferential face extends between the first helical gear tooth and the second helical gear tooth. An involute form taken within a transverse plane of the circumferential face remains constant over the width.
