TURBO ENGINE COMPRISING A DAMPING FLUID FILM FOR DAMPING A GUIDE BEARING OF A SHAFT OF THE TURBO ENGINE AND METHOD OF ADJUSTING THE THICKNESS OF SUCH A DAMPING FLUID FILM

摘要

A turbo engine comprising a housing (1), a shaft of the turbo engine (2) extending axially, a guide bearing (3) for guiding the shaft of the turbo engine (2) in the housing (1), the guide bearing (3) comprising an inner circumferential ring (31 ) rigidly connected with the shaft of the turbo engine (2) and an outer circumferential ring (32) mounted in receiving means (4) of the housing (3) and enclosing rolling members (33), wherein a damping cavity (C), intended for receiving a damping fluid in order to form a damping fluid film for damping the guide bearing (3), is radially delimited between an outer surface of the outer ring (31) and an inner surface of the receiving means (4),in which turbo engine the outer surface (S1) of the outer ring (32) and the inner surface of the receiving means (4) are conical surfaces.
