Abstract:
The method is used for uniforming temperature in a shaft supported by a fluid bearing during rotation of the shaft; a journal portion of the shaft is located inside the fluid bearing; at least one passage is provided inside the shaft at least along the journal portion so to cross it; at least one flow of heat-exchange fluid is established in the at least one passage; the method allows to overcome the problems due to the “Morton effect”. A bearing system implementing the method is advantageously used in a turbomachine.

Claim (Index 10):
A bearing system comprising\n a fluid bearing, a shaft with a journal portion located in front of pad or pads of the fluid bearing, a sleeve arranged at said journal portion and at least one groove arranged in said journal portion and covered by said sleeve, wherein the journal portion comprises at least one passage extending at least from a first side of the fluid bearing to a second side of the fluid bearing, the or each passage being arranged for a flow of a heat-exchange fluid during rotation of the shaft across the journal, wherein said at least one passage is laterally delimited by said at least one groove and said sleeve.
