KOMBINERAT RADIAL- OCH AXIALLAGER

摘要

This invention relates to an improved self-lubricating sleeve and thrust bearing configuration, wherein lubrication of the thrust bearing surface may be augmented by an additional supply of oil. The sleeve bearing includes a circumferential oil receiving slot disposed in the upper half thereof and a plurality of axial oil feeding grooves which extend generally downward in a radial direction and in communication between the circumferential oil receiving slot and the thrust bearing surface. A portion of the oil supply that is distributed to the sleeve bearing lubrication port arrangement to initially lubricate the sleeve bearing surface and subsequently the thrust bearing surface by axial leakage along the journaled shaft is diverted to the circumferential oil receiving slot, from which the oil may be conveyed downwardly through passages to each of the axial oil feeding grooves by means of gravity to directly supply the thrust bearing surface with an additional source of lubrication and thereby avoid starvation of the thrust surface while providing a lower thrust bearing operating temperature.
