摘要： A polytetrafluoroethylene is added to a base resin consisting essentially of polyether ether ketone so that the proportion of polytetrafluoroethylene becomes 0.1 to 50% by weight based on the resin layer and dispersed in the form of particles in the base resin, whereby when the resulting resin layer is bonded to a backing metal to form a composite bearing, the peel strength of the resin layer per se and mechanical strength such as bonding force or the like between the backing metal and the resin layer can be inhibited from being deteriorated. When polytetrafluoroethylene having a molecular weight of 300,000 to 500,000 is used, it can be more easily dispersed in the form of particles in the base resin.

摘要： A method of manufacturing a multilayer material including a back metal and a metal plate made from a metal differing from the back metal is disclosed. The method includes heating powder of the metal formed into the metal plate in a reducing atmosphere so that an oxide on a surface of the metal powder is deoxidized, and spreading the deoxidized metal powder onto the back metal and irradiating laser beam having an energy density of 10 to 100 kW/cm2 onto the metal powder spread on the back metal so that the metal powder is partially heated to be melted, while the laser beam is moved relative to the spread metal powder, and quenching the melted part of the metal powder at an underside of the back metal so that the melted part is rapidly solidified, whereupon the multilayer material has a dendritic structure in which the metal plate extends substantially vertically from a surface of the back metal, and the dendritic structure has a crystal grain size equal to or smaller than 0.02 mm at a cut surface thereof parallel to a surface of the back metal and/or a dendritic arm spacing equal to or smaller than 0.02 mm at a cut surface thereof vertical to the surface of the back metal.

摘要： In order to enhance the fatigue resistance and the anti-seizure property while maintaining the embeddability, there is provided a plain bearing comprising a bearing alloy layer, an intermediate layer and an overlay layer sequentially formed on the inner surface of a back metal. The inner surface of the bearing alloy layer is provided with a recess “a” and protrusions “b”, thereby being made into a textured uneven surface. The protrusion has the shape of a oblique square at 45° relating to the circumferential direction, so that when a foreign particle X introduced between sliding surfaces of a shaft and the plain bearing is moved in the circumferential direction in accordance with the rotation of the shaft, the foreign particle X runs against a side edge of the protrusion “b” and moves along the side edge, thereby the embedding of the foreign particle X is promoted. If the foreign particle fails to be adequately embedded, the foreign particle leaves the side edge again.

摘要： A copper alloy sliding material which can bring about superior resistance to fatigue as well as good anti-seizure property without containing any Pb. The copper alloy sliding material is made to have the structure in which both of the hard copper alloy phase and the soft copper alloy phase coexist in a mixture state. On the surface of the sliding material, the soft copper alloy phase comes to have a shape more concave than that of the hard copper alloy phase when receiving a load or when being in a sliding wear relation, in which concave portions is retained lubricant with the result that the anti-seizure property is enhanced. Further, since the soft phase and the hard phase are made of the same copper alloy, the wettability thereof becomes good, and Ni and etc. contained in the hard copper alloy phase are diffused into the soft copper alloy phase, so that the hardness of the boundary portion defined between the phases come to be gradually varied. Thus, because of the unclear boundary, the load received in the hard phase comes to be spread in a wide range without being concentrated at the boundary, so that the fatigue strength is enhanced.

摘要： There is disclosed a sliding member which slidably contacts an counterpart member with friction and in which a friction force is varied without changing a contact pressure. A sliding member 11 is formed by covering a steel plate with sliding materials 13a to 13e different in friction coefficient. In this case, when a sliding direction of the counterpart member 14 is set to directions of arrows A and B, a sliding material 13a of a low friction coefficient is disposed in the middle, and the sliding materials 13b to 13e are arranged so that the friction coefficient gradually increases toward both terminal sides in the directions of arrows A and B of the sliding material 13a. According to the sliding member 11, the friction force increases as the counterpart member 14 moves in the directions of arrows A and B from the middle.

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： 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.
