Objective Hardening teeth on a steel motorcycle gear to a hardness of 48 – 55 HRC
Material Carbon steel gear 6.9” (175mm) diameter
Temperature 2000 ºF ( 1093 ºC)
Frequency 78 kHz
Equipment •Power of 90 kW induction heating system, equipped with a remote workhead containing eight 1.0μF capacitors for a total of 8μF
• An induction heating coil designed and developed specifically for this application.
Process A single turn helical coil is used to heat the gear. The gear is placed on a spindle and rotated at 300-350 RPM’s. Heat is applied for 10 seconds to reach the desired hardness. The gear is immediately quenched to remove the heat, dried and then coated with a lubricant.
Results/Benefits Induction heating provides:
• Easy control of depth of hardness
• Energy savings due to efficiency of process
• Hands-free heating that involves no operator skill for manufacturing
• Even distribution of heating
