摘要： PROBLEM TO BE SOLVED: To improve abrasion resistance by forming substantially whole hard particles in a coating layer, which contains a solid lubricant adhering to the surface of aluminum alloy or steel alloy, a resin-based binder, and a hard particles, into spherical particles. SOLUTION: For a spherical hard particle, a particle made of oxide such as SiO2 , Al2 O3 , CrO2 , carbide such as SiC, and nitride such as Si3 N4 can be used, and the particle is provided with higher hardness than a counterpart shaft, which is usually made of carbon steel or alloy steel, and desirable hardness is Hv200 or more. A mean particle diameter is 5μm or less, and all the particles are provided with spherical shapes desirably, however, mixture of a very small quantity of particles formed into shapes other than a sphere is allowable. The spherical hard particles are firmly connected together by means of a binder and hardly abraded and mildly lap the counterpart shaft. On the other hand, a solid lubricant is developed on the bearing surface so as to improve a friction property, so that abrasion loss of the bearing material as a whole is greatly reduced. As the abraded face of the bearing is not roughened, discontinuity of the lubricating oil is hardly caused while seizure is also hardly caused.

摘要： PROBLEM TO BE SOLVED: To improve fatigue resistance and load resistance by providing a specific lubricating film formed by coating a bearing basic surface formed of a copper bearing alloy. SOLUTION: A bearing is constituted of a bearing base body and a lubricating film 3, and the bearing base body is constituted of a copper bearing alloy or may be lamination 2 of the copper bearing alloy in a back plate 1 of steel plate or the like. The lubricating film 3 comprises a 30 to 90wt.% solid lubricant and a 70 to 10wt.% thermosetting binder, and thickness of the film is 2 to 10μm. In the thermosetting binder, at least one kind of polyimide resin, epoxy resin and phenolic resin is used. The copper bearing alloy is hard as compared with an aluminum alloy, and plastic deformation of the lubricating film by a load received under a use condition is suppressed. Consequently, in a fine part receiving a severe load and uneven contact, conformity of the lubricating film is generated, and a lubricating effect is easily obtained. Consequently, excessive wearing, observed in the lubricating film of the bearing base body formed of the aluminum alloy, is prevented from being generated, and fatigue strength of a total unit of the bearing is also improved.

摘要： PROBLEM TO BE SOLVED: To improve conformability of a slide bearing applied with a Bi-based overlay wherein harness related to conformability is several times more than Pb.
SOLUTION: In the slide bearing attached with the Bi-based overlay to a slide face side of a lining comprising a copper based bearing alloy, the Bi-based overlay 3 with Ag
2 S deposited on at least a surface side is more superior than a Pb-based overlay. The overlay contains 0.1-10 wt.% Ag. Ag concentration is substantially uniform in a thickness direction in the overlay. It is characterized by that the Ag concentration is relatively low in a lining neighborhood side in the thickness direction in the overlay.

摘要： PROBLEM TO BE SOLVED: To effectively prevent fretting abrasion between a housing and a bearing metal over a long period. SOLUTION: The bearing metal 5 is mounted on an internal surface (an internal surface of the housing) of a first mounting hole 2a of a large end part 2 of a connecting rod. A hard film having hardness >=Hv1000 is formed on a surface having smaller surface roughness of the internal surface of the housing and the internal surface of the bearing metal 5. Wear is surely prevented on the surface covered with the hard film by the hard film having high hardness and difficult to wear over a long period. As for the hard film formed on the surface having smaller surface roughness, also the surface roughness of the hard film itself becomes small according to surface roughness of a surface to be formed and also mating attackability that the hard film itself has becomes small. Therefore, wear resistance in both of the surface covered with the hard film and a surface on a mating side having no hard film formed can be highly maintained over a long period.

摘要： PURPOSE:To obtain the composition capable of forming the lubricating films maintaining good abrasion resistance and further improved in seizure resistance. CONSTITUTION:This composition for forming lubricating films comprises 3-30-wt.% of a binder and 70-97wt.% of a solid lubricant selected from MoS2, WS2, BN, graphite and carbon fibers. The binder comprises a resin selected from a polyimide resin, an epoxy resin and a phenolic resin, and a film-forming auxiliary. Since the composition contains the solid lubricant in a high concentration and the film-forming auxiliary, the solid lubricant is strongly held in the formed lubricating film. Since the initial conformability is thereby good, the seizure resistance of the lubricating film is excellent. Further, since the falling of the lubricating film is prevented, the abrasion resistance of the lubricating film is improved.
