Induction Hardening Gears Teeth
Description
Induction Hardening Gears Teeth With High Frequency Heating System
Objective Heat the teeth of a soft steel seatbelt retraction gear to 1700Ā°FĀ (926.7ĀŗC) within two seconds for hardening.
Material #4130 steel seatbelt retraction gears, water vortex quenchingĀ tank, electronically controlled air valves, adjustable timers
Temperature 1700 Ā°F(926.7ĀŗC)
Frequency 200Ā kHz
Equipment ā¢ DW-UHF-10kW induction heating system equipped withĀ a remote workhead with 1.0 Ī¼F capacitance
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A four-turn helical concentrating coil is specially designed toĀ deliver uniform heat to the steel seatbelt retraction gear. TheĀ parts are positioned in the coil above the quenching tank andĀ held in place with a vacuum rosette fixture. Power is appliedĀ for two seconds to heat the part. The parts are then expelledĀ into the quench tank for cooling.
Results/Benefits Induction heating provides:
ā¢ Uniform and repeatable results
ā¢ Energy efficient
ā¢ Non-contact heating
