The development of possibilities of machines depends on the production of bearings that can work at high rotating speeds. A modern type of bearing that is used in mechanical industry is an induction heating bearing. This bearing has several advantages.
Induction heating bearings do not need a lubricating substance. There is no mechan- ical contact between working parts of the bearing. It works silently with little friction. The lifetime of this bearing is much longer than that of a conventional one.
Analytical methods for the analysis of thermoelec- tric problems in induction bearings are not convenient.
For the model presented, we use the finite element method to carry out calculations. The heating of in- duction bearings should be carefully examined, when the gap between the working parts is small because temperature increases can cause the bearing to seize up......
