In a bearing device of an exhaust gas turbocharger having tandem rolling-contact bearings, the bearing support rings (5,6) have dogs (16) on their mutually facing end surfaces, each of which dogs penetrates into an opposite recess (17) with axial clearance (18) and tangential clearance (19). An even number of rotationally symmetrically located spring rods (7) extend from a bearing flange (8) connected to the bearing housing (2) through the bearing support rings (5,6) and into a support ring (9) connected to the bearing housing (2), a centrally located collar (14) on the spring rods being located alternately, without clearance, in one or the other bearing support ring (5,6). In this bearing device, the effective bending length (L) of the spring rod (7) is relatively large compared to the total width of the bearing (B). By this means, the bending stress in the spring rods (7) can be kept low or the axial installation length (B) of the bearing device can be reduced. |
