    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 ball bearing for a cryogenic application including an inner ring and an outer ring positioned around the inner ring. The inner ring and the outer ring define a raceway therebetween. The ball bearing includes a plurality of rolling balls disposed in the raceway and a slug separator positioned between and slidingly engaging each of adjacent pairs the rolling balls. The slug separator defines an exterior surface thereon, which has a recess extending at least partially into the slug separator. The recess is configured to flow cryogenic fluid therethrough.

    摘要： A rolling guide unit has a separator to adjust an interval between any two adjacent rolling elements. The separator is made to have flexibility or elasticity enough to afford any desired elastic deformation, even with keeping sufficient mechanical stiffness or rigidity to positively admit the interaction among the rolling elements inclusive of a circular shell. The separator is comprised of axially opposite end sides depressed inward to fit over the adjacent rolling elements, a circular shell to define an outside contour of the separator, and fingers lying in the depressions in a way extending from the shell towards centers of the depressions so as to make elastic contact with the rolling elements. Each finger has a surface facing the associated rolling element, the surface being made into any one of a depressed spherical surface, a depressed conical surface and a depressed pyramid surface.

    摘要： A spacer for a linear motion apparatus is to be interposed alternately between balls arranged in an endless circulation passage of the linear motion apparatus. The spacer has a body portion comprising spherical retaining surface portions formed for supporting the balls on both end portions thereof in an advancing direction of the spacer when moving in the endless circulation passage and a circumferential surface portion constituting an outer peripheral portion of the spherical retaining surface portions. The spherical retaining surface portion has a radius of curvature smaller than a diameter of the ball and the circumferential surface portion is provided with a groove extending in the circumferential direction thereof so that one of the spherical retaining surface portions is elastically deformable towards another one thereof. The spacer is preferably applicable to various kinds of linear motion apparatus. Further, rollers as rolling members may be utilized in place of the balls.
