摘要： A centrifugal separator and a method for separation of particles from a gas stream is disclosed. The separator includes a frame, a gas inlet and a gas outlet. A centrifugal rotor is arranged to be rotatable in the frame around a rotational axis and includes a separating member. A central gas chamber in the rotor communicates with a radially inner portion of the separating member and the gas outlet. A space surrounding the rotor communicates with a radially outer portion of the separating member and the gas inlet. A drive provides rotation of the centrifugal rotor for separating particles from the gas stream being conducted from the space surrounding the rotor, through the separation member and towards the central gas chamber. A ring-formed sealing arranged between and in sealing contact with the first frame portion and the centrifugal rotor. This improves the separation performance of a centrifugal separator for separation of particles from a gas stream, by reducing pressure losses and leakage from the central gas chamber.

摘要： A bearing member for supporting a rotatable axle includes a bearing housing; at least one bearing inserted into the bearing housing, wherein the bearing is configured to receive a rotatable shaft extending through the bearing; and a tilting member arranged around the bearing housing. The tilting member includes a pack of annular discs forming a through hole for receiving the bearing housing, wherein each of the annular discs includes a plurality of apertures extending through each of the discs and wherein the tilting member further includes a sleeve element provided in each of the apertures for holding the annular discs together as a stack and for receiving a fastener for attaching the tilting member to the bearing housing or said stationary machine element. The bearing member further includes at least one fastening element extending through a sleeve of the tilting member and attaching the tilting member to the bearing housing.

摘要： A centrifugal separator is configured for processing a product by separating a relatively, heavy component and a relatively light component therefrom. The centrifugal separator includes a spindle supported by a stationary frame, A drive unit acts on a rotating member mounted on the spindle to rotate the spindle. A centrifuge rotor mounted to the spindle encloses a separation space. An upper bearing housing is mounted to the stationary frame and supports bearings including an outer bearing ring attached to the upper bearing housing and an inner bearing ring attached to the spindle. The upper bearing housing is mounted to the stationary frame via an elastic member permitting the upper bearing housing and the spindle to move radially, and via an upper tilting member permitting the spindle to tilt during operation of the centrifugal separator.

摘要： Herein a centrifugal separator is disclosed. The centrifugal separator includes a housing, a spindle, and a rotor. The spindle is only journalled in a bearing arrangement fixedly positioned in the housing at the first axial end portion. The centrifugal separator includes a seal arranged between the spindle and the housing. The seal is arranged at a distance from the bearing arrangement where the spindle is subjected to deflection. The seal includes a cylindrical inner surface associated with the housing, a circular slot in the spindle or in a rotating member associated with the spindle, and a piston ring arranged in the slot and abutting against the cylindrical inner surface.
