The researching of eddy current Induction replacer for bearing race snap

Against the problem of disassembly and assembly department for interference fitting inner ring of bearing, The develops a replacer based on the line-fiequency induction heating technique, the device has the functions of radial adjustment and self-centering, it can realize the rapid heating and nowearing dismounting at the same time, The basic principle of the device has been introduced, and the mathematic models of coil number of windings and skin depth have been provided. The experiments indicates that the replacer has high heat efficiency,and it can be used in the different working condition, so it has a good applying prospect.
