Title:
PROCESS AND APPARATUS FOR INDUCTION QUENCHING OF GEAR TEETH
Document Type and Number:
Japanese Patent JPS5230209
Kind Code:
A
Abstract:
A method and apparatus for obtaining full tooth width induction hardening of gear teeth. The method comprises attaching gear teeth shaped non-magnetic material templates to the opposite sides of the gears in close proximity to but spaced from the sides of the gear teeth. The gear teeth are then progressively induction hardened by passing a current intensifier between the aligned teeth of the templates and the gears while maintaining current flow to the intensifier for the full width of travel of the intensifier between the gear teeth. In the preferred embodiment the faces and roots of the templates are slightly undersize relative to the faces and roots of the gear teeth and the tops of the teeth of the template are slightly oversize and extend beyond the tips of the teeth of the gear.
