摘要： PURPOSE:To obtain an Al-Sn alloy for a bearing with enhanced fatigue and seizing resistances at high temp. and a bearing device by adding a specified amount each of Cr and Cu, Mg, Pb, Bi or In to an Al-Sn alloy and press-welding a backing steel strip to the resulting alloy. CONSTITUTION:A backing steel strip is press-welded to an Al-Sn alloy for a bearing consisting of, by weight, 3.5-35% Sn, 0.1-1.0% Cr, 1-10% Si and the balance essentially Al or further contg. =1 kind of element selected from Pb, Bi and In. A bearing device for an internal combustion engine, etc. is formed with the composite Al-Sn alloy material. Since precipitates formed by adding Si are dispersed in the Al matrix of the alloy, the alloy has an effect of trimming off the polishing burr of a nodular graphite cast iron shaft, and the precipitates cause hardly migrating and aggregating phenomena in the alloy. Accordingly, a stable oil film is formed to enhance the wear resistance.

摘要： PURPOSE:To improve wear resistance and fatigue resistance by forming a sliding bearing by pressing a back metal of a steel plate on an aluminum alloy which is made of Zn, Si, Pb or In and the rest of Al. CONSTITUTION:A sliding bearing is formed by pressing a back metal of a steel plate on an alloy which is made of Zn 0.5-8.0wt%, Si below 0.05-2wt% and Pb or In 0.1-5.0wt%, while assigning Al as the substantial remainder. Proper lubrication resulting from the Zn, wear resistance from hard substance of the Si, fatigue resistance from the interacting effect of them and fitness and seizure resistance from the Pb, In are improved.

摘要： PURPOSE:To obtain a bearing device of an internal combustion engine with superior fatigue, wear and seizing resistances by using spheroidal graphite cast iron as a shaft material and a Cr rich Al-Sn alloy as a bearing material. CONSTITUTION:An alloy consisting of, by wt., 3.5-35% Sn, >1.0-7.0% Cr and the balance essentially Al is used as a bearing material. In order to manufacture bearings using this alloy, the alloy is press-welded to a backing steel strip and annealed several times to increase the bonding strength. At this time, precipitated Al-Cr intermetallic compound prevents the migration of Al grain boundaries and inhibits the growth of Al grains, so Sn grains are not made coarse by the annealing. Since this fact is applicable to the case where the alloy is set at a high temp. comparable to that of the annealing, the fatigue strength is enhanced by preventing softening. The resulting bearing device has high seizing surface pressure, superior fittability and seizing resistance, and it brings a smooth friction torque change.

摘要： PURPOSE:To obtain the titled alloy having superior resistance to seizing, fatigue and wear under high load at high temp. and suitable especially for a sliding bearing surface of nodular graphite cast iron by dispersing a specified number of Si particles having a specified particle size in an Al matrix. CONSTITUTION:This bearing Al alloy contains 0.5-5wt% Si and at least 5 Si particles having at least 5mum particle size per 3.56X10 mm. cross-section, and by press-welding the alloy to a backing steel strip, a bearing material is obtd. By adding 0.1-2% Cu and/or Mg to said alloy as optional components, deterioration in the hardness at high temp. can be reduced. 0.1-1% Cr and/or Mn as well as Cu and/or Mg may be added so as to increase the effect of Cu and/or Mg, and 0.1-1% Cr may be added furthermore.

摘要： PURPOSE:To obtain a bearing capable of being used under a high load and high temp. condition, by a method wherein an element showing special compatible effect such as Mn or Fe is added to an Al alloy containing tin for the bearing of an internal combustion engine and the dimension and the distribution density of a particle formed by adding said element is specified. CONSTITUTION:An Al alloy containing, on the basis of wt% 1-35 Sn, 0.5-11 one or more of Mo, Ni, Zr, Co, Ti, Sb, Cr and Nb and substantially comprising the remainder Al is bonded to a backing metal to obtain a bearing. 5 or more particles per 3.56X 10 mm. consisting of >one kind of aforementioned elements and having 5-40mu length are contained in the optional parts of the alloy of the bearing, which can be used without an overlay. In this case, when the added element is below the lower limit, special compatible effect which contributes to the flattening of recessed and protruded parts of a partner material becomes defficient and, when exceeds the upper limit, said effect is not enhanced and the lowering in fatigue strength and baking load is apt to be generated. When the length of the particle is below the lower limit, the special compatible effect is not exhibited and, when exceeds the upper limit, fatigue strength is lowered. As to the distribution density of the particle, when it is below the lower limit, the special compatible effect is not recognized.
