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 1700ยฐFย (926.7ยบC) within two seconds for hardening.
Material #4130 steel seatbelt retraction gears, water vortex quenchingย tank, electronically controlled air valves, adjustable timers
Temperature 1700 ยฐF(926.7ยบC)
Frequency 200ย kHz
Equipment โข DW-UHF-10kW induction heating system equipped withย a remote workhead with 1.0 ฮผF capacitance
โข An induction heating coil designed and developedย specifically for this application.
Process A four-turn helical concentrating coil is specially designed toย deliver uniform heat to the steel seatbelt retraction gear. Theย parts are positioned in the coil above the quenching tank andย held in place with a vacuum rosette fixture. Power is appliedย for two seconds to heat the part. The parts are then expelledย into the quench tank for cooling.
Results/Benefits Induction heating provides:
โข Uniform and repeatable results
โข Energy efficient
โข Non-contact heating
