ABSTRACT:
In a method and a device for controlling a lubrication film between a bearing surface and a shaft surface of the bearing assembly an electric circuit is provided, interconnected between the shaft and the housing of the bearing, in which a thermoelectric voltage is produced by friction heat which is generated at a contact between the shaft and the bearing when a break in the lubrication film occurs, and which termoelectric voltage is used as a voltage source of the electric circuit.
