Shrink fitting aluminum pulley to insert inner bearing


Objective: To heat aluminum pulley for insertion of an inner bearing for the automotive industry.


Frequency: 283 kHz


Equipment:
  • Ambrell 2 kW induction heating system, equipped with a remote workhead containing two 0.33μF capacitors for a total of 0.66μF;
  • A coil specifically designed for this application.

Material: Aluminum pulley 2.3” (60mm) OD x 1.6” (40mm) ID x 1” (27mm) high and inner bearing 0.7” (17.8mm) high x 1.6” (40mm) dia.


Temperature: 464 °F (240 °C)


Process:

A three turn helical coil is used to heat the aluminum pulley. The pulley is heated to 464 ºF (240 ºC) in 20 seconds to expand the inner diameter and then the inner bearing is inserted to form the completed part.


Benefits:
  • Defined and controlled heat pattern;
  • Process easily integrated into automated system;
  • Even distribution of heating.
