Abstract (en)
[origin: WO2004018843A2] The invention concerns a plain bearing for an internal combustion engine turbocharger shaft (10), in particular in a motor vehicle. Said bearing comprises a cylindrical bearing bush (16) provided with an axial bore (18) for receiving the turbocharger shaft. In said bore (18), each axial end of the cylindrical bearing bush (16) comprises a first plain bearing surface (22) for radially housing the turbocharger shaft (10), and each front axial surface of the cylindrical bush bearing (16) comprises a second plain bearing surface for axially housing the turbocharger shaft (10). In an axial section (20) between the plain bearing first surfaces (22), the bore (18) is designed so as to allow a gap between one wall of said bore (18) and the turbocharger shaft (10). In the zone of each first plain bearing surface (22), the outer periphery of the cylindrical bush bearing (16) comprises a lubricant supply in the form of an annular groove (30), first orifices (32) being arranged and shaped so as to form a lubricant duct connection between the annular groove (30) and the corresponding first plain bearing surface (22), and second orifices (34) being arranged and shaped so as to form a lubricant duct connection between the annular groove (30) and the corresponding second plain bearing surface (24).
