摘要： A radial magnetic bearing may include an annular housing including a radial outer wall disposed between radially outer ends of two annular axial end plates and an isolation sleeve which may include a helical arrangement of a plurality of ferromagnetic wires. The isolation sleeve may be an annular structure extending axially between the two annular axial end plates, and the isolation sleeve and the annular housing may define an isolation cavity therebetween. The radial magnetic bearing may also include an isolation sleeve retainer configured to maintain a position of the isolation sleeve between the two annular axial end plates. The radial magnetic bearing may further include a plurality of laminations disposed adjacent the isolation sleeve and about a shaft of the rotating machine. A gap may be defined between the plurality of laminations and the isolation sleeve.

摘要： An auxiliary bearing system having a sleeve through which a shaft extends. A gap may be defined between the sleeve and the shaft when a primary bearing system supports the shaft, and the sleeve may engage and rotate with the shaft when the primary bearing system does not support the shaft. An oil ring may extend circumferentially around the sleeve and rotate in response to the rotating sleeve when the sleeve engages and rotates with the shaft. The rotating oil ring may distribute lubricant within the auxiliary bearing system.
