ABSTRACT:
A self contained, "package", bearing system, has relatively rotating and sliding, precisely formed, truncated spherical, journal and bearing surfaces with a high hardness and with a low surface roughness, that operate on a thin hydrodynamic film of pressurized lubricant, when the bearing system is operated under any combination of axial and radial loads. It optionally contains either a supply of dry lubricant, or normally a capillary supported, self-contained reserve of fluid lubricant, and a system of "internally discharging" throwers, for keeping the fluid lubricant within the system, to promote a long operating life.
Lubricant re-circulation channels at the ends of the bearing and the inherently lower rates of flow of lubricant from the ends of truncated spherical bearings facilitates achieving long operating life. Grooves and recesses are optionally included in the bearing surfaces for enhancing the axial load capacity. Axial wear of the softer bearing surface maximizes the axial load capacity without grooves.
One embodiment consists of only two bearing parts surrounding one journal part, and a reserve of lubricant.
Preferred embodiments use hardened and sealed powdered metal bearing surfaces, and harder journal surfaces, that permit the development of hydrodynamic load capacities that are high enough to permit the system to replace package bearing system that utilize ball type rolling elements.
