Abstract
Official abstract text for this publication.
A method for heat treating a gear having gear teeth includes removably mounting the gear on a work-piece holder, moving one of either a magnet assembly or the work-piece holder to bring the gear and the magnet assembly into heating proximity, rotating the magnet assembly for a desired amount of time while said magnet assembly and gear are in heating proximity to each other to heat treat surfaces of the gear teeth, moving one of either the magnet assembly or the work-piece holder relative to the other to bring different surfaces of the gear into heating proximity with said magnet assembly, and repeating for each opposed pair of gear teeth surfaces until all said gear teeth surfaces are heat treated.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for heat treating a gear having gear teeth; the method including: (a) removably mounting the gear on a work-piece holder; (b) moving at least one of either a magnet assembly and the work-piece holder to bring the gear and the magnet assembly into heating proximity; (c) rotating the magnet assembly for a desired amount of time while the magnet assembly and gear are in heating proximity to each other to heat treat surfaces of the gear teeth;…
