    摘要: A reversible vertical journal bearing with a self contained closed circuit lubrication system, directed toward ceiling fan applications, is disclosed. Lubricant pumping, from a reservoir, is accomplished by an array of throttled, high pressure, triangular pumping cavities on the journal surface. The array is completely symmetrical about the journal axis, so that unidirectional lubricant flow is produced at either direction of journal rotation. The lubricant is collected in a manifold at the top of the bearing, and it is gravity fed back into the reservoir. Optimum design parameters for a stable high load bearing capability device are indicated.

    摘要: A thrust plate is provided. The thrust plate includes a first side surface and a second side surface. The thrust plate also includes an inner surface and an outer surface extending axially between the first and second side surfaces respectively. Further, the inner and outer surfaces of the thrust plate define an inner diameter and outer diameter respectively. The thrust plate further includes a number of mounting apertures extending between the first and second side surfaces. The number of mounting apertures is defined proximate to the outer diameter of the thrust plate. A wear layer is positioned radially inward from the mounting apertures. The wear layer is integrated into a stepped portion defining a wear prone area on the first and/or second side surfaces. Further, the wear layer is made of a material different from that of a core of the thrust plate.

    摘要: A hermetic reciprocating compressor, in which a bearing structure to support a rotating shaft is improved to minimize frictional contact between the parts of the compressor, thus reducing noise of the compressor and improving compression efficiency of the compressor. In the hermetic reciprocating compressor, a first annular bearing seat is formed around an upper edge of a shaft bore of a frame to seat therein a first radial bearing which sustains loads of a rotating shaft. The first radial bearing is a self-aligning radial bearing which allows the rotating shaft to self-align due to a clearance angle of the first radial bearing, even when a desired perpendicular arrangement of the shaft bore relative to a cylinder block is not formed, due to a mechanical tolerance of the frame. The first radial bearing sustains both axial loads of the rotating shaft and horizontal loads acting in the rotating shaft due to rectilinear reciprocation of a piston, thus reducing the losses caused by friction between the rotating shaft and the frame. In addition, since the rotating shaft self-aligns due to the first radial bearing, it is possible to reduce the losses caused by friction between a compression chamber and the piston and between the rotating shaft and the frame.
