Shrink Fitting of Bearings
A multi-turn helical coil delivers uniform heat to the entire range of the bearing sizes in the transverse mode.
Aluminum motor housing; automotive
Induction heating is fast, presents significant energy savings over an electric oven, requires a more modest footprint than an oven and can be easily integrated into an automated process
Shrink-fitting an aluminum motor housing
The customer was using a cold press, but it was creating part defects. This was resolved with induction heating: the process took just two minutes compared to 40 minutes and they were able to achieve their targeted production rate. Induction's fast, precise heating means the client can count on consistent results once it is implemented into their process.
Shrinkfitting a steel mud pump liner
A twenty-turn helical coil is used to heat the chain. The chain is fed through the coil at a rate of 1 meter per minute to reach the desired 1760 °F (960 °C) for the tempering process...
shrink-fitting a carbide ring into a valve seat
A three turn helical coil is used to heat the steel valve seat. The steel valve seat is placed in the coil and heated for 50 seconds to enlarge the center hole & drop the carbide ring in for the shrink-fitting process.
shrink-fitting an assembled wrist pin into a connecting rod
Induction heating provides more accurate control of heat vs a flame burner, it heats only the knuckle, not the whole part, it prevents discoloring due to lower temperature used and increases productivity due to repeatability & ease of operation. A foot pedal & timer is used.
Shrink fit a motor shaft and roller
Processing with induction heat saves power and time. The complete tube does not have to reach the desired temperature as it does when heating with an oven. Being able to selectively heat a zone allows for a much quicker transfer of heat.
Shrink-fitting a Camshaft Gear
Heating a camshaft gear with a bore size of 1.630 inch to shrink fit over a steel shaft that has a diameter of 1.632 inch. A temperature of 500F is required for the gear to expand 0.002 inch in order to slip over the shaft.
