Abstract:
A method of manufacturing a shift gearwheel with coaxially disposed and axially projecting shift teeth, which have an axial undercut, said method comprising the steps of:a) bringing into mutual engagement, a shift gearwheel blank having coaxially disposed and axially projecting preformed shift teeth, the flanks of which extend in an axial direction, and a forming tool having corresponding axial tooth recesses, wherein the preformed shift teeth of the shift gearwheel blank become engaged into the tooth recesses with a clearance;b) setting the shift gearwheel blank and the forming tool in gyratory motion relative to one another in such a way that contours of the tooth recesses in the forming tool move in a pressing and material-shaping manner over the flanks of the performed shift teeth of the shift gearwheel blank so as to form an undercut; andc) separating the thus machined shift gearwheel blank and the forming tool from one another.
