摘要： PURPOSE:To improve the seizure resistance and wear resistance of the bearing alloy by adding a specified amt. of Sr to an Si-contg. Al-Sn-Pb series alloy and regulating the shape of Si to a spheroidal one. CONSTITUTION:The bearing alloy is constituted of, by weight, 3 to 35% Sn, 0.1 to 11% Si, 0.1 to 10% Pb, total 0.1 to 4% of Mg and/or Zn, 0.01 to 0.3% Sr and the balance Al. Furthermore, in the Al matrix 1, Si grains 2 having a spheroidal or elliptical shape or a roundish shape in the tip are dispersed and precipitated. By the grains 2, the ideal of the point contact can nearly be obtd. to moreover increase the lubricity and wear resistance. Moreover, even if high-speed and rapid high loads are applied, the alloy does not flaw the mating shaft, and the matrix 1 has no notch effect therein as well as has stabilized strength and excellent wear resistance. Furthermore, Sn-Pb alloys 3 are present more adjacently to the grains 2, by which the lubricity can drastically be improved.

摘要： PURPOSE:To improve wear resistance and antiseize property by providing shallow recesses extending in the circumferential direction and corresponding to oil holes of respective journal parts, from which lubricating oil is supplied or flowed, at least on the bearing surface of one sliding bearing. CONSTITUTION:On the bearing surfaces 8g, 8h of respective half bearings 8a, 8b in at least one sliding bearing 8 assembled with a connecting rod 3, recesses 11 are provided corresponding to oil holes 10a of a journal part 5. By forming the recess 11 corresponding to the oil hole 10a in this way, because of local existence of the recess 11 at the corresponding part of the oil hole 10a in addition to keeping lubricating ability by clearance 12, the corresponding part of the oil hole 10a does not suffer seizure and other trouble, and lubricating ability can be maintained at maximum, even if the lubricating oil film at the clearance 12 becomes extremely thin due to high load.

摘要： PURPOSE:To improve antiseizure property of the title bearing material by forming an overlay layer consisting of soft metal on an iron group bearing material with back plate and impregnating the soft metal identical to an overlay layer in the hollow portions of a sintered layer. CONSTITUTION:An overlay layer 7 made ot soft metal is formed on an iron group sintered layer 5 and soft metal identical to the overlay layer 7 is impregnated in the hollow portions of the iron group sintered layer. Antiseizure property is thereby improved so that it is most suitable for a high speed and high load bearing such as an internal combustion engine.

摘要： PURPOSE:To reduce frictional resistance at the time of starting so as to improve anti-seizure property and the life of the title bearing material by adding a lower layer consisting of soft metal impregnation layer, an intermediate overlay layer and a surface overlay layer to the sintered material of an iron group bearing, in an iron group bearing material with a back plate used for an internal combustion CONSTITUTION:A soft metal impregnation layer is formed at the lower portion of an iron group sintered material layer 2, an intermediate overlay layer 4 is formed on a head portion by galvanizing, etc., further, an surface overlay layer 5 is formed and a bearing is thereby constructed. Accordingly, even if the bearing is used in the severe field of using condition such as a high load internal combustion engine, frictional resistance at the time of starting is smaller than conventional one, antiseizure is superior and it can be used for a long time.
