Abstract

Centrifugal separator, the rotor (1) of which is supported and driven by a shaft (2). The shaft (2) is supported in a frame (4) by means of a bearing (6), which is arranged in a bearing housing (7). The bearing housing (7) bears against the frame (4) via a damping device (8) comprising a first element (9), which follows the oscillating movements of the shaft (2), at least one second element (10), which is arranged movable relative to the frame and at least one elastical element (11), which presses the second element (10) radially inwards against the first element (9) at the contact area (12). In order to provide a centrifugal separator with a damping device, which during operation gives rise to a low and constant generation of heat, the centrifugal separator is designed with a device (15), which forms a bowl (14). The bowl (14) has an upwards directed opening (16) and is so located at the first and second element (9, 10) that at least a part of the contact area (12) is located in the bowl (14).
