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： PURPOSE:To provide a connecting rod of an internal combustion engine which can restrain fretting for the use of a long term by forming synthetic resin layers on both contact faces of a bearing metal mounting face and a contact face of the bearing metal with a connecting rod main body and a cap. CONSTITUTION:A synthetic resin layer 5 is formed on the bearing metal mounting faces of a connecting rod main body 1 and a cap 2. A synthetic resin layer 6 is formed on the contact faces of the bearing metal 3 with the connecting rod main body 1 and the cap 2. For the synthetic resin of the synthetic resin layers 5, 6, PAI(polyamidimide) is used, wear resistance and load resistance against lubricating oil temperature are excellent, and adhesion to the surface of base material is also excellent. For the synthetic resin layers 5, 6, a resin coating layer is favorably used, in which the hardness is 1H-4H in pencil hardness, and a sort or two sorts or more among MoS2, PTFE (polytetrafluoroethylene), graphite as solid lubricant are contained of 5% or less in the whole weight ratio, favorably 1-3wt%.
