PROBLEM TO BE SOLVED: To provide a sliding bearing having performance equal to or more than that of a rolling bearing, the rolling bearing used for a scroll compressor loaded on an automobile being replaced by the sliding bearing.SOLUTION: In this sliding bearing, a sliding layer is formed by burning on a back metal thereof. The sliding layer is made of 5-60 wt.% graphite, average radius of which is 5-50 μm, degree of graphitization of which is 0.6 or more, in which an average shape coefficient (Y) defined as in the following of particles except fine particles each having a radius of 0.5 times or less of the average radius is 1-4, and which includes particles having a shape coefficient (Y) within a range (Y)=1-1.5 at 70% or more in the ratio of the number, and polyimide resin and/or polyamideimide resin as residues.
Abstract:
A process for drawing wire employing a lubricant comprising perfluorocarbon compounds (PFCs), including aliphatic perfluorocarbon compounds ( alpha -PFCs) having the general formula CnF2n+2, perfluoromorpholines having the general formula CnF2n+1ON, perfluoroamines (PFAs) and highly fluorinated amines (HFAs), and perfluoroethers (PFEs). Such fully and highly fluorinated carbon compounds exhibit a very high degree of thermal and chemical stability due to the strength of the carbon-fluorine bond. Further, because the compounds are fully fluorinated, and therefore do not contain chlorine and bromine, they have zero ozone depletion potential (ODP). Further, because the compounds are photochemically non-reactive in the atmosphere, they are not precursors to photochemical smog and are exempt from the United States Environmental Protection Agency (EPA) volatile organic compound (VOC) definition. Further, because they are volatile, the compounds are easily removed at the end of the process without need for an additional cleaning step. The process provides wire at significantly higher production speeds and longer die life with improved quality and less byproduct debris.

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 lubrication mechanism of a strain wave gearing is disposed in an interior space of an externally toothed gear and comprises a powder-accommodating bag that stores solid lubricant powder. A diaphragm of the externally toothed gear is repeatedly deflected during the driving of the strain wave gearing. Vibration or deflection is repeatedly imparted to the powder-accommodating bag and the solid lubricant powder is discharged from a powder discharge hole formed in the powder-accommodating bag into the interior space. A site to be lubricated is lubricated with the solid lubricant powder discharged into the interior space. Harmful effects due to a large amount of the solid lubricant powder being supplied to the site to be lubricated at one time can be resolved, and a necessary amount of the solid lubricant powder can be continuously supplied to the site to be lubricated.
