Designing of a New Induction Heating Shaft Bearing Replacer by Using FEM

This paper designed a new shaft bearing replacer using for bearing inner race based on the induction heating technique by finite element method (FEM). The regularities of distribution of the electromagnetic and thermal field in the replacer had been simulated during the course of induction heating, the FEM simulation results not only proved the existence of the eddy skin effect, but also achieved the design parameters of the replacer by coupling the electromagnetic and thermal Held. By experimental verification, the replacer can realize fast disassembling of the bearing inner race, which assembled on an axle with magnitude of interference.
