摘要： PURPOSE:To provide a sliding bearing provided with a surface layer made of Pb alloy having the excellent tensile strength and the excellent adhesive strength against a lining layer. CONSTITUTION:A surface layer 3 consists of multiple columnar crystals 41, which exist under the distributed condition, and an aggregate 5 of particle crystals for filling between the columnar crystals 41. The columnar crystals 43 give the influence to the adhesive strength of the surface layer against a lining layer and the tensile strength of the surface layer 3 within the surface along a sliding surface 3a. This influence is relaxed by the aggregate 5 of the particle crystals.

摘要： PURPOSE:To provide a plain bearing improved in the fitness of the surface layer in the initial stage of the start of sliding and improved in the wear resistance of the surface layer after the lapse of the initial period in starting the sliding. CONSTITUTION:A surface layer 3 is constituted of a composite layer 31 precipitately formed on a lining layer 22 and a single layer 32 precipitately formed on the composite layer 31. The composite layer 31 is formed of a Pb alloy matrix 4 and fine grains 5 dispersed into the matrix 4 and improving its wear resistance. The single layer 31 is constituted of the assembly of columnar Pb alloy crystals 71 having square piramidal tip parts 6. In the initial stage of the start of sliding, the surface area of the sliding face 3a is expanded by each square piramidal tip part 6, by which the surface layer 3 can be provided with sufficient oil preserving properties, and furthermore, by preferentially wearing the side of the vertex (a) of the piramidal tip part 6, the initial fitness property of the surface layer 3 can be improved. After the lapse of the initial period in the starting the sliding, composite effect by the fine grains 5 can be obtd., so that the wearing amt. of the surface layer 3 is reduced.

摘要： PURPOSE:To provide a plain bearing provided with a surface layer excellent in wear resistance. CONSTITUTION:A surface layer 3 is constituted of the assembly of the columnar crystals 4 of a Pb alloy. The concn. of the alloy elements in the peripheral area (a) of each columnar crystal 4 is made higher than that of the alloy elements in the inside area (b) excluding the peripheral area (a). In such a manner, the metallic structure is made dense in the peripheral area (a) to increase its hardness. In the wear progressing stage of the surface layer 3, when the sliding face is formed by the edge faces in the columnar main body of each columnar crystal 4, reticular parts C having high hardness formed by the peripheral area (a) of each columnar crystal 4 are dispersed on the sliding face.

摘要： PURPOSE:To provide a plain bearing provided with a surface layer excellent in seizing resistance. CONSTITUTION:The sliding face 3a of a surface layer 3 is formed of the pyramidal crystals 5 of a Pb alloy in which the vertex (c) is directed to the side of the sliding face 3a. The sliding face 3a is provided with plural bulging areas (b) dispersed on its whole body. In such a manner, since the space between the main area (a) excluding each bulging area (b) and the opposite member (x) functions as an oil puddle in the sliding face 3a and simultaneously the surface area of the sliding face 3a is expanded by the pyramidal crystals 5, the surface layer 3 has sufficient oil preserving properties, and furthermore, in each bulging area (b), the side of the vertex (c) is preferentially weared to improve its initial fitness.

摘要： PURPOSE:To provide a sliding bearing provided with a surface layer having excellent resistance to wear and seizing. CONSTITUTION:A surface layer 4 has an aggregate of the quadrangular pyramidal crystals 5 of a Pb alloy forming a sliding face 4a. One of the adjacent crystals 5 is bitten into another, hence the internal stress of both crystals 5 is increased, and the surface layer 4 is greatly hardened. Furthermore, the surface area of the sliding face 4a is increased by the crystal 5, a sufficient oil holding property is imparted to the surface layer 4, the apex (a) of the crystal 5 is preferentially worn, and the initial fitness is improved.

摘要： PURPOSE:To obtain a plain bearing capable of adapting to severe sliding conditions by rendering a cast structure to a lining layer and specifying the crystal form of a Pb alloy. CONSTITUTION:When a lining layer 3 of a Cu alloy and a surface layer 4 of a Pb alloy are successively formed on the body 12 of a plain bearing, a cast structure is rendered to the lining layer 3 and the crystal form of the Pb alloy is regulated so that (h00) faces expressed by Miller indices are oriented at 70-100% orientation index. A seizing resistant bearing is obtd.
