BEARING LUBRICATING METHOD AND BEARING LUBRICATING DEVICE

摘要

PROBLEM TO BE SOLVED: To give an internal pressure without impairing the lubricating function of oil-air.;SOLUTION: In a bearing lubricating method for lubricating a bearing device 1 by its oil-air, the bearing device 1 is arranged in opposed ring-like spaces 4 sealed by contact type seals 5 between two ring bodies 2, 3 concentrically arranged in and out of the diametrical direction, the oil-air is supplied into opposed ring-like spaces 1 by a necessary pressure, and the supplied oil-air is discharged outside the opposed ring like spaces 4 through an oil-air discharge passage 7. Air is allowed to act on the oil-air discharge passage 7 from outside by an ejector pump 20 to give internal pressure to the opposed ring-like spaces.;COPYRIGHT: (C)2000,JPO
