| 20100059506 | Inductor for Inductor Hardening of Metal, Rod-Shaped Toothed Racks - An inductor for induction hardening of a metallic rod-shaped toothed rack, wherein a first outer surface of the toothed rack provided with the teeth is substantially planar and a remaining second outer surface of the toothed rack in cross-section is profiled, wherein the inductor has a substantially rod-shaped first inductor element that extends parallel to a longitudinal axis of the toothed rack. The first inductor element extends across an entire length of the toothed rack to be hardened along the first outer surface provided with the teeth and hardens the first outer surface of the toothed rack. The the toothed rack and the inductor during the hardening process are arranged stationarily. | 03-11-2010 |
