The invention refers to a support device for a centrifugal separator having a centrifuge rotor (2), which is provided in a frame (1) to be rotatable about an axis (x) of rotation by use of a bearing member (4). The support device is provide between the bearing member and the frame and permits relative movements between the rotor and the frame. The support device has two first stiff portions (6', 6'') which are substantially immovable in relation to the bearing member, two intermediate elastic portions (7', 7'') and two second stiff portions (1', 1'') which are substantially immovable in relation to the frame. The first stiff portions, seen in an axial section, adjoin a respective intermediate portion along a first borderline (8', 8'') and the second stiff portions, seen in the axial section, adjoin a respective intermediate portion along a second borderline (9', 9''). At least one of the second borderline slopes in relation to the axis (x) and the extensions of the second borderlines (9', 9''), which extensions are directed outwardly from the axis, intersect. |
