Date: 6/1/2001

A revolutionary new induction heating system is being introduced to the automotive industry for the heat treatment of crankshafts. This technology involves heat treating the crankshaft journals using stationary inductors. At the same time, SHarP-C process does not use clamp-type coils. Features of V-6 hardening/tempering machine are discussed in this presentation as well as some aspects of computer modeling and features of microstructure.

Since its introduction crankshaft hardening has demonstrated advantages over conventional crankshaft hardening of V-6 crankshafts. Those same advantages now are realized in processing V-8 crankshafts.


SHarP-C - Advanced Non-rotational Crankshaft Induction hardening and Tempering Technology

Authors: Don L. Loveless, Valery I. Rudnev, LAL, GCD, HM
Publication: Heat Treatment of Metals
Date: 1/1/2001

The authors introduce a new system for induction heat treating crankshafts in which, unlike conventional processing, the crankshaft is not rotated. In a comparison with the operation of traditional induction hardening machines, they outline the technical benefits of the new stationary approach, being more cost-effective, energy efficient and space-saving technology.


Advanced Non-Rotational Induction Crankshaft Hardening Technology Introduced to Automotive Industry

A revolutionary new induction heating system is being introduced to the automotive industry for the heat treatment of crankshafts. This technology involves heat treating the crankshaft journals using stationary inductors rather than the cumbersome methods of conventional crankshaft hardening processes. In conventional methods, the inductors must follow the offset rotation of the connecting rod journals, requiring the movement of massive induction fixtures as the crankshaft rotates. In the method described here, both the crankshaft and inductors remain stationary, resulting in improved hardness patterns and a significant reduction in floor space requirements for the equipment.


Gear Heat Treatment by Induction

Authors: Valery Rudnev, Don L. Loveless, Brian L. Marshal
Publication: Proc. of 20th ASM Heat Treating Conference, St. Louis, October, 2000
Date: 10/1/2000

This presentation is based on materials published in Gear Technology Magazine ("Gear heat treatment by induction", March, 2000). At the same time, there are some additional information regarding to features of "gap-by-gap" induction hardening of gears, induction tempering of gears, as well as some other aspects of this technology.
