摘要： Disclosed is a sliding bearing in which a heat emission property of the sliding bearing is improved without affecting the original function of an overlay layer. An overlay layer is formed on a higher load-side bearing half, and extends circumferentially from a central portion thereof toward each of opposite ends thereof. Any overlay layer is not formed on a lower load-side bearing half, so that a bearing alloy remains exposed to the surface of this bearing half.

摘要： In a sliding bearing in which a bearing metal layer is covered with a coating layer, the coating layer comprises a thermosetting resin as a base resin and soft metal particles dispersed in the base resin in an amount of 0.1 to 10% by volume based on the volume of the coating layer. The soft metal is harder than the base resin and has a higher thermal conductivity than the base resin, so that the wear resistance and anti-seizure property of the sliding bearing are improved. In particular, when the soft metal particles are of copper, silver, tin, zinc or the like, the soft metal particles react with the sulfur contained in a lubricating oil to form a thin metal sulfide film excellent in lubricity on the surface of the particles, whereby the coefficient of friction is made smaller.

摘要： A bearing structure with a low coefficient of friction and a distinguished wear resistance is obtained by coating a shaft with a resin composition comprising PAI and 5 to 50% by weight of PTFE, based on total resin composition and/or coating a bearing with a resin composition comprising PEEK and not more than 50% by weight of PTFE, based on total resin composition. By adding potassium titanate whiskers or a lead compound to the bearing resin composition, more improved coefficient of friction and wear resistance are obtained.

摘要： There is disclosed a half thrust bearing of a substantially semi-circular shape. A thrust relieve 22, slanting toward a confronting end of the half thrust bearing progressively away from a bearing surface of a half thrust bearing, is formed at each of circumferentially-spaced opposite end portions of the bearing surface by pressing (cold forging), so that those portions of the bearing surface, disposed adjacent respectively to the thrust relieves 22, are higher in strength than the other portions of the bearing surface. With this construction, even if a thrust collar of a crankshaft abuts against localized portions of the bearing surface disposed adjacent to the thrust relieves 22, a bearing alloy will not subjected to premature fatigue and separation.

摘要： A main-load side bearing metal piece on which a heavy load is imposed is coated on an inner surface thereof with a thin overlay having a uniform thickness. Meanwhile, a non-load side bearing metal piece is coated on an inner surface thereof with an overlay having a uniform thickness greater than that of the overlay formed on the inner surface of the main-load side bearing metal piece. With this construction, the bearing metal piece shows excellent load carrying capacity and fatigue resistance because the overlay formed on the inner surface thereof is thin, while the non-load side bearing metal piece shows excellent foreign matter embeddability and conformability because the overlay formed on the inner surface thereof is thick. Moreover, since there are formed the overlays each having a uniform thickness in respective inner surfaces of each of the bearing metal pieces, and therefore it is possible to reduce the manufacturing cost.

摘要： It is an object of the invention to improve wear resistance and an anti-seizure property of a portion , on which a radial load operates owing to tension of a cogged belt or a V-belt, of a plain bearing for an engine. A main shaft portion of a crankshaft is in uneven contact with an upper half bearing owning to tension of the cogged belt and/or the V-belt. A branch groove is formed in a portion forwarder than an oil groove formed on the bearing surface of a upper half bearing of a plain bearing, the branch groove branching off from the oil groove. When an engine stops, lubricant is stored within the branch grooves, and when the engine restarts, the lubricant within the branch grooves is immediately supplied to the uneven contact portion of the main shaft portion though the rotation thereof.

摘要： There are provided a plain bearing which is excellent in oil retaining property and wear-resistant property. The plain bearing has a number of fine grooves which are parallely formed with one another and extending in the circumferential direction on the inner surface of the bearing, the fine grooves comprising deep grooves and shallow grooves. When this bearing is used as a plain bearing, a large amount of lubricating oil can be retained in the deep grooves and the shallow grooves so that a plain bearing which is excellent in anti-seizure property and wear-resistant property can be obtained. Further, even if the shallow grooves will have been worn out by wear and tear during use of extended period of time, the anti-seizure property and the wear-resistant property can be stably maintained by the lubricating oil retained in the deep grooves.
