Einrichtung zum Einwalzen von vorverzahnten Zahnraedern

摘要

Rolled or machine-cut gears are finished by a rolling action in engagement with a die roll comprising a guide gear intermediate a pair of side gears. The outer gears form chamfers on the tooth edges while the guide gear, when working without flank clearance against the work gear, prevents flank bulging and effects smoothing. The teeth of the work gear are substantially confined by the teeth of the three gears of the die roll to prevent bulging of material due to the effect of chamfering as well as effecting burr trimming and smoothing.
