を含有することを特徴とする。With respect to the bearing characteristics of this alloy system, the anti-seizure property is improved as the Sn content is increased, but the fatigue resistance is lowered. On the contrary, if the Sn content is small, the fatigue resistance is improved. However, the non-seizure property tends to decrease. Japanese Patent Application No. 3-1744
In No. 9, by adding Pb, excellent anti-seizure property is maintained even if the Sn content is small. Further, in Japanese Patent Application No. 3-17450, improvement has been made mainly by the fact that addition of Bi does not reduce fatigue resistance even if the Sn content is large. The present invention pursues those characteristics and synergistic effects. That is,

各層成分の組成を前記特許請求の範囲に記載の如く限定
する理由（上限、下限の決定理由）とその作用効果につ

であるのが好ましい。Next, the reasons for limiting the composition of each layer component in the bearing metal for a large engine of the present invention as described in the above-mentioned claims (the reason for determining the upper and lower limits) and their effects will be listed below. (1) Steel backing metal layer The thickness of the steel backing metal layer in which conventionally publicly known steel, for example, general structural carbon steel defined in JIS is used, is preferably 1 to 20 mm. (2) Intermediate adhesive layer This is for improving the adhesion between the steel backing metal layer and the bearing alloy layer, and is conventionally publicly known pure Al, or Cu, Si, Mn, Zn, etc. when higher strength is required. It is possible to use an Al alloy in which 0.1 to 2% by weight or less is added in a total amount of 1 type or 2 types or more. In that case, if the added element is less than 0.1%, the effect of addition does not appear and it is meaningless. If it exceeds%, it becomes brittle and not suitable for practical use. The thickness of the intermediate adhesive layer is 0.01-0.15mm
Is preferred.

なじみ性と埋収性を劣悪させるので５％を上限とした。(3) Bearing alloy layer The thickness of the bearing alloy layer is preferably 0.2 to 3 mm. (a) Sn: 35 to 65% A component whose main purpose is lubrication. If it is less than 35%, both the non-seizure property and the embeddability are insufficient, and if it exceeds 65%, the fatigue strength is insufficient and the castability is also impaired. (b) Pb and Bi: 0.5 to 10% in total Pb and Bi both improve the lubricating property and conformability of Sn. Bi is further alloyed with Sn to form Sn.
The hardness of the phase is increased, which contributes to the improvement of fatigue resistance. That is, co-existence of both Pb and Bi in the Sn phase improves anti-seizure property and fatigue resistance at the same time. P
When the total amount of b and Bi is less than 0.1% and less than 0.5% in total, there is no effect of addition, and when the total amount exceeds 10%, the melting point is too low and the temperature is high. In addition to causing insufficient strength, it causes manufacturing problems. (c) Cu: 0.1 to 1.5% Cu is a component for the purpose of improving fatigue resistance, which is a bearing characteristic, and improving adhesive strength with the surface layer.
If it is less than 0.1%, there is no effect of addition, and if it exceeds 1.5%, the alloy hardness becomes too large, and the initial conformability,
Poor embeddability. Moreover, since ductility is impaired, manufacturing becomes difficult. (d) One or two or more of Mn, Ni, Si, Ag, Mg, Sb, and Zn The total amount: 5% or less A component to be added for the purpose of improving the mechanical strength of the Al matrix. If the total amount exceeds 5%, the initial running-in property and the embeddability are deteriorated, so the upper limit was made 5%.

It contains Pb or Sn or their alloys as a main component, and Cu for improving performance. And / or In may be added as an additional element. Further, in order to improve the adhesion between the bearing alloy layer and the surface layer, a thin layer such as nickel plating may be provided between the bearing alloy layer and the surface layer. In addition to the electroplating, PVD or the like may be used as a means for coating the surface layer. The thickness of the surface layer is preferably 1 to 30 μm.

ルに適用できるものである。The present invention has the following excellent effects. 1) From the test results of Table 5 and Table 6, the fatigue resistance is improved by adding Bi without impairing the non-seizure property. For example, the product No. of the present invention. 7 is prior art product N
o. 19 to which 3.5 wt% of Bi was added. The seizure test results are both 1025 kgf / cm 2 , but the fatigue test results show that the prior art product No. 19 is 225 kgf /
Although fatigued at cm 2 , the product No. 7 is 250 kg
It can be seen that f / cm 2 causes fatigue and the fatigue resistance is improved. This is because the hardness of the Sn phase is increased by adding Bi and alloying with Sn, which contributes to the improvement of fatigue strength. Conventionally, Al bearing alloys containing high Sn tended to have reduced fatigue strength due to the large amount of Sn.
However, by adding Bi as in the present invention, the decrease in fatigue strength could be suppressed. 2) From the test results of Table 5 and Table 6, the anti-seizure property is improved without impairing the fatigue resistance by adding Pb. For example, the product No. of the present invention. No. 1 is a prior art product No. 1
6 is obtained by adding 5.0% by weight of Pb. The fatigue test results are both 200 kgf / cm 2 , but the seizure test results show that the prior art product No. No. 16 of the invention product was seized at 1025 kgf / cm 2 . 1 is 1050 kgf /
It can be seen that seizure and non-seizure property are improved at cm 2 .
This is because the added Pb improved the lubricating characteristics of Sn. 3) The above results are obtained by the synergistic effect of the improvement in fatigue resistance obtained by adding Bi and the improvement in non-seizure property obtained by adding Pb. 4) Therefore, the present invention was able to achieve the initial purpose. That is, the present invention can be applied to the recent bearing metal for a large engine, which is required to have both excellent anti-seizure property and fatigue resistance.
