Date Apr. 2, 1998The present invention relates to novel lubricant compositions comprising a solid lubricant and a binding agent in water medium suitable for lubricating steel-steel interfaces such as tractor-trailer couplings, rail-wheel systems and other heavy duty applications. The invention also relates to compositions described above which include friction modifiers with high or very high and positive coefficients of friction such that the coefficient of friction is considerably higher than the solid lubricant. The invention further relates to compositions comprising a binding agent and a friction modifier with a very high and positive coefficient of friction in a water medium.

Abstract:
An improved lubricating oil composition comprising a major amount of oil of lubricating viscosity; a minor amount by weight of solid particles effective to improve the lubricating properties of the composition; and a minor amount by weight of at least one of certain co-polymers derived from the polymerization of (1) an N-vinyl-pyrrolidone, and (2) an oil-soluble acrylic ester.
Abstract:
The present invention provides a grease composition (7) which has a low friction and a low viscosity and is durable at a high temperature and a grease-sealed bearing (1) in which the grease composition is enclosed. The grease composition contains base oil, a thickener, and an additive. The base oil contains an ionic liquid consisting of a cation component and an anion component. The additive contains a corrosion inhibitor such as nitrites, molybdates or dibasic acid salts. The thickener is fluorine resin such as polytetrafluoroethylene. The grease composition (7) is applied to a periphery of each rolling element (4) of the grease-sealed bearing (1).
Abstract:
PROBLEM TO BE SOLVED: To provide a grease composition having improved high-temperature durability while attaining friction reduction and viscosity reduction, and to provide a grease-sealed bearing in which grease is sealed. SOLUTION: The grease composition comprises a base oil, a thickening agent and an additive, wherein the base oil contains an ionic liquid composed of a cation component and an anion component, the additive contains a corrosion inhibitor such as nitrites, molybdates and dibasic acid salts, and the thickening agent is a fluororesin such as polytetrafluoroethylene resin. The grease-sealed bearing is sealed with the grease composition 7 at least around a rolling element 4. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a novel lubricant and a friction modifier containing a solid lubricant and a binding agent as needed in an aqueous medium. SOLUTION: The problem to be solved is appropriate to lubricate steel-steel interfaces (e.g., tractor-trailer couplings, rail-wheel systems and other heavy duty applications). The invention is attained by a composition containing a friction modifier having a high or very high positive coefficient of friction such that the coefficient of friction is considerably higher than that of the solid lubricant. The invention further relates to a composition containing the binding agent and the friction modifier having a high or very high positive coefficient of friction in an aqueous medium.
