ABSTRACT:
A self-aligning bearing assembly includes a bearing sleeve having a spherical outer contour supported at one side of the equator thereof by a plurality of arms having spherically concave ends making intimate contact with the spherical outer contour. A retaining member engages the spherical outer contour at the other side of the equator to secure the bearing sleeve against linear displacement but to permit angular adjustment about the center of the spherical outer contour. A wick member having fingers fitting into windows in the bearing sleeve conducts a lubricant such as oil to the tangential surface of a shaft. A reservoir containing an absorbent material having a lubricant absorbed therein and available therefrom surrounds the bearing sleeve with the absorbent material in contact with the wick member. Lubricant flingers or oil throwers or oil slingers spaced from each end of the bearing sleeve throw lubricant escaping past the ends of the bearing sleeve into rings of absorbent material such as felt from where the lubricant is transported to, and reabsorbed into, the reservoir and thus is made available for reuse. A relatively large intimate surface contact between the ends of the arms and the spherical outer contour permits rapid conduction of heat away from the bearing sleeve.
