摘要： PURPOSE:To provide an Al-Sn bearing alloy having a specified composition contg. Sn, Cr, etc., showing remarkably enhanced wear resistance and suitable for use as a material for a car internal combustion engine, etc. CONSTITUTION:This Al-Sn bearing alloy with remarkably enhanced fatigue and wear resistances consists of, by wt., 3.5-35% Sn, 0.1-1% Cr, 1-10% in total of one or more among W, Ce, Nb, V, Ba, Ca, etc. and the balance Al. This alloy is generally used as a composite Al-Sn alloy obtd. by pressure-welding a backing steel sheet. When a bearing device for an internal combustion engine is manufactured using this alloy as a bearing material and nodular graphite cast iron as a shaft material, this alloy does not hinder the bearing performance unlike a conventional Al-Sn alloy and can enhance the wear resistance. By further adding

摘要： PURPOSE:To prevent the flowing-out of the oil in a certain amount or more by installing a cock having a small-diameter hole into an oil introducing pipe and drilling an opened hole onto the wall surface of the oil introducing pipe on the downstream side from the cock. CONSTITUTION:An oil introducing pipe 7 is equipped with a partitioning cock 9 having a small-diameter hole 9a and has an opened hole 10 on the downstream side. Therefore, the oil under the cock 9 flows out, and when the pressure of the vacant part becomes equal to the atmospheric pressure, a surface tension acts into the small-diameter hole 9a, and the rise of air is prevented. Therefore, the oil which fills the upper part over the cock 9 does not flow out.

摘要： PURPOSE:To uniformly oil a trolley line without causing bliding in an oiling hole even if air temperature changes by providing an oiling member having the oiling hole in a tube belonging thereto and having a small coefficient of thermal expansion while providing an interval member opposing, spaced in a prescribed interval, to the hole. CONSTITUTION:Oil passages 9a are bored in a tube 9 at every fastening positions of the tube, and the oil passages 9a are respectively covered with oiling members 24. The oiling member 24 is formed by metal having a smaller coefficient of thermal expansion but higher rigidity than those of the tube 9. The above member has a cylindrical part 25 for covering an outer circumference of the tube 9 therewith and blocking the oil passages 9a and a flange part 26. A cylindrical space partitioned by the oiling member 24, a partition member 60, and a flange part 26 forms an oil reservoir 61, in which oil is stored at all times irrespective of an oiling or non-oiling period. Since an oiling hole 25a for supplying the oil into the trolley line 4 is bored in the metal oiling member 24, dust from the outside sticks to the surface of the oil and does not reach the oiling hole 25a without exerting a bad influence thereon even if the air temperature and a mounting state change.

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 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.
