Method and apparatus for manufacturing a shift gearwheel and shift gearwheel manufactured by same

摘要

The subject matter of the invention is a method of manufacturing a shift gearwheel (1) with coaxially disposed and axially projecting shift teeth (5), which have an axial undercut. To said end, a shift gearwheel blank (1) having preformed shift teeth (5) and a forming tool (16) having corresponding tooth recesses (18) are brought into engagement and set in gyratory motion relative to one another. Further described are a device for effecting the method and a shift gearwheel (1), which may be manufactured by the method. The latter is notable for the fact that the flanks (23, 24) of the shift teeth (5) upon completion of the manufacturing method are concave so as to produce an undercut.
