Bearing support arrangement for rapidly rotating rotors

A bearing support for rapidly rotating rotors, in particular for the bearing arrangement of turbocharger shafts, which is disposed in a housing (2) and radially supports at least one bearing (3) with respect to the housing (2), an annular gap (25) which is connected to an oil supply arrangement (31) and is used as a trapped oil damper being formed between said housing (2) and the bearing support arrangement (10), wherein

• a) the bearing support arrangement (10) is of one-piece design,
• b) the bearing support arrangement (10) comprises an outer flange (11) connected to the housing (2), a gimbal ring (12) and an inner bearing bush (13) which receives the bearing or bearings (3),
• c) in each case a circumferential slot (14, 15) is formed both between the gimbal ring (12) and the outer flange (11) and between the gimbal ring (12) and the bearing bush (13),
• d) the gimbal ring (12) is respectively connected to the bearing bush (13) and to the outer flange (11) via two inner and two outer webs (16, 17) which interrupt the respective circumferential slot (14, 15),
• e) the annular gap (25) is formed between the bearing bush (13) and the housing (2) and is arranged axially offset with respect to the gimbal ring (12),
• f) in each case at least one centering surface (22, 23) is arranged both on the outer flange (11) and on the housing (2), said centering surfaces (22, 23) being arranged so as to correspond to one another and so as to be concentric with respect to the bearing/bearings (3).
