Method for producing lubricant applied to at least one of raceway surface or rolling element of rolling bearing device, or method for producing lubricant applied to at least one sliding surface of bearing member or shaft member of sliding bearing device

摘要

PROBLEM TO BE SOLVED: To provide a lubricant having self-lubricating property for relaxing stress applied by self sliding when received the stress, to be able to form a coated film on a rolling element and an orbital plane or a slide plane of a bearing element and a shaft member only by applying the lubricant to at least one of the rolling element and the orbital plane or at least one of the shaft member and the bearing member and to maintain the self lubricating property regardless of rolling speed and load of the shaft member and regardless of operation temperature of a bearing device.SOLUTION: There is provided a lubricant agent by depositing a granular fine particle of metal oxide in an organic compound having 3 properties; it has lower melting point than descent point of flow point of a lubricant consisting of paraffinic base oil, it has higher boiling point than a temperature where the granular fine particle of hard magnetic metal oxide is generated, and it is incompatible with the lubricant, further mixing the lubricant with the organic compound and stirring them to prepare a suspension and using the suspension for a bearing device.SELECTED DRAWING: Figure 1
