Verfahren zum Herstellen ringförmiger Zahnräder für Antriebswellen.

摘要

A method for providing ring gears (14) for heavy-duty ring gear/pinion gear gear-sets (12/14) is provided. The method comprises providing a near net ring gear forging (106) which is machined on other than the root and flank tooth surfaces (90), subjected to a carburizing heat treatment (92) and then subjected to a grinding operation, preferably utilizing cubic boron nitrate grinding tools, to finish machine the tooth flank and root surfaces to the final configurations thereof (94).
