  • Method of and device for forming a clutch gear toothing on gearwheels for change speed gears
    Patent number: 6494072
    Abstract: A method of manufacturing a gearwheel (10) by clutch gear tooth forming with an axial undercut and a roof-shaped entry geometry consists in causing the gearwheel blank to perform a rotating movement and to cause profiled shaping tools in the form of rolls with external toothing, toothed racks or hollow rolls with internal toothing to perform a motion in rolling contact for engagement in the material, and in initiating the corresponding shaping operation by a radial or axial feeding motion, respectively.
