PRODUCTION METHOD OF LUBRICANT APPLIED ON AT LEAST ONE OF RACEWAY SURFACE OR ROLLING ELEMENT OF ROLLING BEARING DEVICE, PRODUCTION METHOD OF LUBRICANT APPLIED ON SLIDING SURFACE OF AT LEAST ONE OF BEARING MEMBER OR SHAFT MEMBER OF PLAIN BEARING DEVICE, OR PRODUCTION METHOD OF LUBRICANT VACUUM-IMPREGNATED INTO POROUS BODY COMPOSED OF SINTERED METAL USED IN OIL RETAINING BEARING DEVICE

摘要

To provide a production method of a lubricant satisfying the followings: a permanent self-lubricating property of the lubricant formed on a rolling element and a raceway surface in a rolling bearing device; a permanent self-lubricating property of the lubricant formed on a sliding surface in a plain bearing device; and no entry into boundary lubrication, no depletion of a lubricating oil, no deterioration of low-temperature startability, and no progression of thermal degradation of the lubricating oil in an oil retaining bearing device.SOLUTION: A lubricant applied on at least one of a raceway surface or a rolling element in a rolling bearing device having a rolling element and an inner ring and an outer ring composed of a soft magnetic material, a lubricant applied on a sliding surface of at least one of a bearing member or a shaft member in a plain bearing device, the shaft member composed of a soft magnetic material, or a lubricant vacuum-impregnated into a porous body including a sintered metal in an oil retaining bearing device having a shaft member composed of a soft magnetic material is produced with a suspension having a ferromagnetic metal fine particle 1 surrounded by a spherical fine particle 2 of the lubricating oil and dispersed in an aggregate of the spherical fine particle of the lubricating oil.SELECTED DRAWING: Figure 1
