1. Device to support the rotating shaft (3) of a centrifugal machine, of the type comprising two bearings or groups of bearings (4, 5, 6; 18, 19) situated at a certain axial distance one from the other, each being mounted rigidly in a non-rotating elementary body (9, 26) which is joined elastically (14, 30) to the fixed frame (1, 2) of the machine, an annular space (12) being arranged between these two bearings or groups of bearings, which space is able to form an oil chamber, this chamber being delimited on the exterior by a substantially cylindrical wall (10b, 34, 33b) at the ends of which the bearings or groups of bearings are mounted, characterized in that the two elementary bodies (9, 26) which mount the bearings or groups of bearings (4, 5, 6; 18, 19) are independent one from the other and in that each of them comprises a tubular extension (10b; 33b) which extends towards the other body, these two extensions being connected one to the other in a tight manner by a deformable casing (34) so as to constitute the fixed exterior wall of the oil chamber (12), the inner rotating wall of which is directly realized by the periphery of the shaft (3) itself. |
