Verfahren zur Herstellung von Zähnen eines Zahnstangengliedes

摘要

A variable ratio rack has a linear array of teeth. The teeth in the linear array are disposed at a plurality of final tooth angles. In order to form the rack, a linear array of teeth is cut in a workpiece. The teeth in the linear array of cut teeth have a tooth angle which is less than the largest tooth angle of the plurality of final tooth angles and greater than the smallest tooth angle of the plurality of final tooth angles. After the linear array of teeth has been cut in the workpiece, the cut teeth are deformed to have tooth angles corresponding to the final tooth angles.
