Breakthrough in Induction Hardening Shafts

Breakthrough in Induction Hardening Shafts Dr. Valery Rudnev, Bill West, Steve Fillip Inductoheat Inc. Presentation reviews recently developed innovations related to induction hardening of various automotive powertrain transmission and engine components, including but not limiting to case hardening of output shafts, flanged shafts, yoke shafts, sun shafts, intermediate shafts, drive shafts and others. Thanks to several innovative designs (patented and patent pending) important goals were achieved. Coil life was increased approximately nine times. Process sensitivity has been dramatically reduced. Other benefits include measurable improvement in process robustness, coil reliability and maintainability. Quality of induction hardened components was substantially improved thanks to novel inverter design that allows controlling independently frequency and power.
