Abstract:
PROBLEM TO BE SOLVED: To provide a low friction sliding mechanism greatly capable of lowering a frictional coefficient of a sliding member. SOLUTION: This low friction sliding mechanism is constituted of sliding members sliding with each other and a lubricant interposed between them. The sliding member comprises a resin material containing hydrophilic fine particles in at least a part of sliding faces. The lubricant contains a friction regulator comprising an oxygen-containing organic compound or an aliphatic amine compound. The hydrophilic fine particles are primary particles with a ≥1 nm and COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
An aqueous lubricant used for plastic working of metallic material which comprises (A) a water soluble inorganic salt, (B) lubricative agent selected from molybdenum disulfide and graphite and (C) wax, wherein the components are dissolved or dispersed in water, and wherein a concentration ratio (weight ratio) of (B) /(A) is in the range of 1.0 SIMILAR 5.0 and (C) / (A) is 0.1 SIMILAR 1. 0. And a method of lubricative film processing on a metallic material, in that the lubricative film formed by applying the aqueous lubricant is in a dried weight of 0.5 SIMILAR 40g/m . A water soluble inorganic salt (A) is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdete and a tungstate. The wax (C) is preferably a natural wax or a synthetic wax which is dispersed in water and has a melting point of 70 SIMILAR 150 DEG C. The aqueous lubricant can be used for imparting excellent lubricity with ease to the surface of a metal having no chemical conversion layer formed thereon.
Abstract:
A rolling bearing which has a satisfactory life at a low cost even under such service conditions that water is incorporated into a lubricant either externally or due to dew condensation, or that vibration has an influence, and is particularly suitable for electrical equipment and accessories of automobile engines, such as alternators. The hydrogen ion index pH of a grease scaled in the interior of the bearing is adjusted to 7 to 13. For attaining similar effects, the pH of the grease is adjusted to 5 to 13 when an organic metal salt or ADTC has been added in a predetermined amount to the grease, when an inorganic compound having an average particle diameter of not more than 2 Ám has been added in a predetermined amount to the grease, or when a diurea compound containing an aromatic amine or a mixture of diurea compounds has been added as a thickening agent to the grease.
Abstract:
PROBLEM TO BE SOLVED: To obtain a lubricant molding slightly cracking or chipping at a low cost regardless of a production method. SOLUTION: The lubricant molding 3a is composed of at least two kinds of higher fatty acid metal salts having different numbers of carbons. The higher fatty acid metal salt contains at least one kind of a filler selected from preferably silica, alumina, tungsten disulfide, molybdenum disulfide, graphite fluoride, graphite, boron nitride, polytetrafluoroethylene (PTFE), ethylene-tetrafluoroethylene (ETFE) and polyvinylidene fluoride (PVDF). The higher fatty acid metal salt is preferably composed of at least two kinds of higher fatty acid metal salts having different metal salts. The higher fatty acid metal salts may comprise resin foam pieces or resin foam blocks mixed therein. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
An oil-soluble reaction product of phosphorus-, low molecular weight basic nitrogen-, and optional boron-containing compounds is provided. This reaction product can solubilize significantly more phosphorus and boron per weight of compound than other known compounds and is used as an antiwear, antioxidant, and extreme pressure additive in lubrication oils.
Abstract:
