摘要： Damping device for a shaft, which supports a centrifugal rotor and is journalled in a bearing in a frame (7) in such a way that an oscillating movement of the shaft relative to the frame (7) is admitted during the rotation of the rotor (5). The damping device comprises a first friction member (8), which is connected to a bearing in such a way that the shaft is rotatable relative to the friction member, and a number of second friction members (10), which are supported by the frame (7) and are distributed around the shaft, each one of the second friction members (10) being arranged to be so kept pressed by a spring force towards the first friction member (8) in a predetermined direction that upon oscillating movement of the shaft (1) perpendicular to this predetermined direction a damping friction arises when the first friction member (8) together with the shaft is moving relative to the second friction member (10) referred to. In order to reduce the heat generation each one of the second friction members (10) is movable relative to the element, which it is supported by or connected to, i.e. the frame (7) or the bearing (3) perpendicular to the shaft (1) and perpendicular to said predetermined direction in a limited distance, which at least is 0.2 mm.
