Heating Shrink Fitting Camshaft Gear

Induction Heating Shrink Fitting Camshaft Gear with IGBT Induction Heater Objective: Heating a camshaft gear with a bore size of 1.630" to shrink fit over a steel shaft that has a diameter of 1.632". A temperature of 5000F is required for the gear to expand 0.002" in order to slip over the shaft. Production is presently done at a rate of 15-20 gears per 24 hour shift by heating the gear on a hot plate. The hot plate heating cycle lasts for approximately 45 minutes. The customer would like to explore the options available in terms of heating times and machine size. Material: Steel Camshaft Gear measuring 7" in diameter, 1" thick, with a bore size of 1.630". Temperature: 5000F Application: A unique three (3) turn helical coil along with the various DAWEI solid state induction power supplies were used to achieve the following results: - 5000F was reached in three (3) minutes while using the DW-HF 5, 5 kW output solid state induction power supply. - 5000F was reached in five (5), eight (8), and ten (10) minutes using the DW-HF-3, 5 kW output solid state induction power supply. - Even heating was observed as a result of the unique three (3) turn helical induction coil. Equipment: DW-HF-35 and DW-HF-55 kW output solid state induction power supplies respectively, including remote heat stations and a unique three turn helical coil made from 3/16" copper tubing and having a 4.4" inside diameter. Frequency: 62 kHz Shrink Fitting Camshaft Gear
