    摘要： A bearing for a hub-mounted vibration suppression system includes an outer ring defining a first outer race and a second outer race. A first inner ring and a second inner ring are disposed in the outer ring. A plurality of rolling elements is disposed between the first inner race and the first outer race. A slug separator separates each adjacent pair of the plurality of the rolling elements. Another plurality of rolling elements is disposed between the second inner race and the second outer race. Another slug separator separates each adjacent pair of the other rolling elements. Each of the plurality rolling elements have first centers that are spaced apart from one another by no more than 15 degrees and/or each of the plurality other rolling elements have second centers that are spaced apart from one another by no more than 15 degrees.

    摘要： A bearing includes: a first raceway member whose outer peripheral surface includes an annular first raceway surface; a second raceway member whose inner peripheral surface includes an annular second raceway surface facing the first raceway surface; a plurality of cylindrical rollers arranged in a circumferential direction such that the cylindrical rollers contact the first raceway surface and the second raceway surface in an annular rolling path along the first raceway surface and the second raceway surface; and a separator adjacent to the cylindrical rollers in the circumferential direction. The separator has a cylindrical shape. An outer peripheral surface of the separator having an annular groove defined by a groove wall surface, a shape of the groove wall surface in a cross section including a center axis being an arc shape. The separator being oriented such that the groove wall surface contacts outer peripheral surfaces of the cylindrical rollers adjacent to the separator in the circumferential direction. The groove wall surface having a curvature radius larger than a curvature radius of each of the outer peripheral surfaces.

    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).
