摘要： In the production of an internal contour with an internal arbor acting on the inner wall of a cup-shaped or annular rotationally symmetrical workpiece, expansion and length change of the workpiece are avoided during cold forming. Thus, gear components with internal teeth are produced that have greater symmetry and higher accuracy. A workpiece provided with a press fit on the outside or a prefabricated workpiece is inserted into the die, and during the cold forming is pressed tightly by friction and rotationally fixed with the rotationally driven internal arbor against the inner wall of the die. After completion of the rolling process of the profile, the workpiece is ejected with an axial ram. The internal arbor is provided with outside profiling and is cantilever-mounted and is fed axially and radially during the rolling.

摘要： 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.
