Definitions
- the present invention relates to a lubricant composition for oil-impregnated bearings. More particularly, the present invention relates to a lubricant composition for oil-impregnated bearings having excellent wear resistance and low coefficient of friction characteristics.
- a sintered oil-impregnated bearing is a self-lubricated state in which a porous body obtained by compacting and further heating metal powder represented by copper, iron, tin, zinc etc. is impregnated with lubricating oil.
- a type of sliding bearing used in Japan This is a low-cost, relatively low-friction, high-precision, self-lubricating system, automotive electronic components, audiovisual equipment, office equipment, home electric appliances, auxiliary storage drive units for computers, etc. It is widely used as a motor bearing at each location.
- the properties required for sintered oil-impregnated bearing oil include good compatibility with the bearing material (does not cause corrosion, sludge, etc.)
- Perfluoropolyether oil is suitable as a sintered oil-impregnated bearing oil because of its excellent thermal stability, low volatility, chemical resistance, resin resistance and temperature viscosity characteristics.
- Patent Document 1 discloses a sintered oil-impregnated oil impregnated with perfluoropolyether oil for the purpose of stabilization of lubricating characteristics and prolongation of bearing life utilizing the low volatility of perfluoropolyether oil. Bearings have been proposed.
- Patent Document 1 Japanese Patent Application Laid-Open No. 5-240251
- perfluoropolyether oils have the disadvantage that they are easily wettable and diffuse because of their low surface tension. Therefore, their leakage and scattering are often a problem.
- Oil-impregnated bearings allow lubricants to be impregnated and held in their holes, and the lubricants are gradually supplied to the sliding surfaces to enable longer life of the bearings.
- perfluoropolyether oil The property of being easy to leak and scattering causes oil to be supplied from the bearing more than necessary and disappears more quickly, thereby shortening the bearing life. In addition, the oil that has exuded from the bearings can contaminate the surrounding environment other than the used area.
- Patent Document 2 proposes a porous bearing filled with a grease containing 0.1% or more of a thickener.
- the thickener itself can not be repelled because the pores of the oil-impregnated bearing can not be repelled, and the thickener is Rather it promotes pollution of the bearing environment.
- Patent Document 2 Japanese Patent Application Laid-Open No. 63-195416
- perfluoropolyether oil is an oil film sufficient for lubrication under severe conditions where the compatibility with metals is worse than ester oils and general synthetic oils such as synthetic hydrocarbon oils. It is inferior to general synthetic oils in terms of wear and friction. In addition, this makes the barrier properties of perfluoropolyether oils worse than common synthetic oils. If additives are added to improve this, compatibility with the non-fluorinated additives that can be added to most common synthetic oils is poor, and various fluorinated additives have been proposed, but However, it is difficult to achieve sufficient wear resistance, low coefficient of friction and anti-corrosion properties, as with general synthetic oils.
- a lubricant composition for oil-impregnated bearings obtained by adding and mixing a fluorocarbon resin powder having a primary particle diameter of 1 ⁇ m or less with a base oil consisting of two specific types of polyfluoropolyether oils.
- this lubricant composition is used for oil-impregnated bearings, it improves the wear resistance, friction coefficient, anti-scattering and leak resistance, but these properties have recently been improved. There is a demand for further reduction while maintaining, and thus, further improvement of the wear resistance and the low coefficient of friction characteristics is required.
- Patent Document 3 Japanese Patent Application Laid-Open No. 2003-147380

If the proportion of the fluorine-containing amide compound added is less than this, the lubricating properties are improved. The purpose can not be achieved, while if it is used at a higher ratio, the inherent performance of the lubricant will be impaired.
