摘要： An axial air movement fan having a plurality of variable pitch fan blades (2), extending radially from a hub (4) rotatable about a main axis (3), each blade (2) further being pivotable about its radial axis to vary the blade pitch. The blades (2) each are mounted on an associated bearing (5) mounted on said hub, the bearing comprising a ball bearing having a first radially inner race (25) fast the blade (2) and a second radially outer race (26) rotationally fast to the hub (4). The balls (14) in the bearing are separated by separators (15), each separator being generally cylindrical and having its cylindrical axis coaxial with the orbital axis (22) of the orbit of the balls (14) and being adapted to rotate about the said orbital axis (22), the side faces of the separator each having a part spherical recess (16) adapted to receive a ball (14). Rotation of the separator (15) about the orbital axis (22) is such as to entrain lubricant in the bearing and to bias the lubricant from adjacent the outer race (26) over the balls (14) towards the inner race (25).

摘要： A multi-stage centrifugal compressor with an integral high-speed motor compressing a stator (52), a rotor (28) carrying permanent magnets (72a-72d), wherein there is a gap (50) between the stator (52) and the rotor (28). The rotor (28) has a magnetic steel rotor shaft (75) rotatably supported at each end by pressurized oil lubricated hydrodynamic bearings (53,54). The compressor also has a plurality of compressor impellers (26,27) mounted to turn with the rotor shaft (75) and a pump (29) for delivering cooling oil to the bearings (53, 54). Also, there is a passageway (66) through the stator (52) for introducing pressurized air within a gap (50) during start up to maintain a positive pressure within the gap thereby displacing oil from the gap (50).
