Abstract

See full text

A method for manufacturing a gear toothing on a metallic workpiece and a tool device for calibration of a gear toothing inlet and/or a gear toothing outlet of a gear of the metallic workpiece. The method includes producing the gear toothing by forming manufacturing and performing a compression process to calibrate a gear toothing inlet and/or a gear toothing outlet of the gear toothing, wherein a gear tooth shape and a gear tooth length are adjusted during the compression process. The tool device includes a workpiece location for accommodating the workpiece, an axially movable die selectively engageable with the gear toothing, the die supporting the gear toothing and predefining the gear tooth shape to be adjusted on the gear toothing inlet and/or on the gear toothing outlet, and at least one axially movable compression ring which calibrates the gear toothing inlet and/or gear toothing outlet by a compression process.
