Note: Hardening teeth on a steel motorcycle gear

Objective:

Hardening teeth on a steel motorcycle gear to a hardness of 48 – 55 HRC

End Product:

Steel motorcycle gear

Equipment:

Ambrell 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. 

Materials:

Carbon steel gear 6.9” (175mm) diameter

Temperature:

2000 ºF ( 1093 ºC)

Frequency:

78 kHz

Testing:

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. 

Benefits:

  • 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
