In a centrifugal rotor (2) for freeing a liquid from solid particles suspended therein and being heavier than the liquid there is delimited a separation chamber (20), in which one or more conveyor screws (29) are arranged to supply separated particles axially along a surrounding wall (17) of the rotor. Each conveyor screw (29) is connected with a drivable bearing member (31) through a transmission shaft (38) extending out through one end wall (13) of the rotor. This bearing member (31) is journalled in the centrifugal rotor (2) and is situated in a transmission chamber (47) formed between said end wall (13) and a further wall (46). The transmission chamber (47) contains a liquid during operation of the centrifugal rotor, which liquid lubricates the bearing surfaces (43, 44) of the bearing members (31) and the centrifugal rotor and also influences the bearing members (31) by a hydraulic force directed towards the rotational axis of the centrifugal rotor, so that the loading of the bearing members on said bearing surfaces (43, 44) is reduced. |
