    摘要:  固体潤滑転がり軸受の内部の潤滑状態を長期間にわたって良好に維持し、軸受寿命を延長する。内外輪(1、2)間でボール(3)の1個おきに配される柱状のセパレータ(4)と、外輪(2)両端部に取り付けられたシールド(6)とボール(3)の配列との間に配される潤滑リング(7)を、グラファイトで形成し、そのグラファイトの配合率を90~100vol%とすることにより、十分な潤滑が行われるようにするとともに、セパレータ(4)の曲げ強度を10~90MPaとすることにより、運転中のセパレータ(4)の破損を防止できるようにしたのである。その結果、内輪転走面(1a)および外輪転走面(2a)とボール(3)との間の潤滑状態が長期間にわたって良好に維持され、軸受寿命の延長を図ることができる。

    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 spherical roller bearing (56, 72) includes an outer ring (20), an inner ring (24), and a plurality of rollers (14) positioned between the outer and inner rings and arranged in a row. The bearing also includes a first separator (10) positioned between adjacent first and second rollers in the row. The first separator includes a first plurality of contact pads (44) that engage the first roller, and a second plurality of contact pads that engage the second roller for maintaining separation and spacing of the first and second rollers. The bearing further includes a second separator (10) positioned between adjacent third and fourth rollers in the row. The second separator includes a first plurality of contact pads (44) that engage the third roller, and a second plurality of con- tact pads (44) that engage the fourth roller for maintaining separa- tion and spacing of the third and fourth rollers. The separators (10) are movable independently of each other.
