ABSTRACT:
The object of the invention is to provide an improved bearing support arrangement for rapidly rotating rotors, with which arrangement the service life of the bearing device is increased and both its fabrication costs and the expenditure on assembly are reduced. This is achieved according to the invention in that the bearing support arrangement (10) is of one-piece design. It 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 the bearings (3). 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). 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). 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). At least one centering surface (22, 23) is arranged both on the outer flange (11) and on the housing (2), the 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).
