Abstract

Case-hardened gears for use in gearboxes transmitting large torques are produced by rough forming tooth gaps in a workpiece carburising the workpiece, finish hobbing the tooth flanks of the workpiece, locally heating the tooth surfaces of the workpiece, and tempering the workpiece. Distortion carburising associated with the is removed by finish hobbing after carburising but before hardening the case. Any minor distortions produced by the hardening and tempering may be removed by very light final grinding.
