(1) Steel back metal layer Conventionally known and publicly used steel, for example, carbon steel for general structure specified by JIS is used. (2) Intermediate layer This is for improving the adhesion between the steel backing metal and the bearing alloy layer. Conventionally known and used pure Al or Cu, Si, Mn, Zn or the like as an additional element when the strength is further required. An Al alloy to which 0.1 to 2% by weight or less in total of two or more kinds is added can be used. In addition, when the additive element is added, if it is less than 0.1%, the effect of the addition is not significant, and if it is more than 2%, it becomes brittle and is not suitable for practical use.

When the content exceeds 65%, the fatigue strength becomes insufficient. It also impairs castability. (B) Bi: 0.5 to 10% Bi alloys with Sn to improve the lubricating properties and conformability of Sn. Further, when Bi is alloyed with Sn, the hardness of the Sn layer increases, which contributes to the improvement of the fatigue strength. Therefore, the fatigue strength is improved without changing the strength of the Al matrix, in other words, without deteriorating the initial conformability. If less than 0.5%, there is no effect of addition and 10%

(C) Cu: 0.1 to 1.5% Cu improves the fatigue strength, which is a bearing characteristic, and also improves the adhesive strength with the surface layer.

In addition, production is difficult because ductility is impaired. (D) 1 of Ni, Si, Ag, Mg, Mn, Sb, Zn

験の結果をそれぞれ示した。The present invention will be described more specifically with reference to the following examples. Tables 1 and 2 show the chemical components of the bearing alloy layer used for the bearing metal of the present invention and the conventional bearing alloy layer. An alloy plate having the composition shown in Tables 1 and 2 and an Al foil were superimposed on each other and passed through a rolling mill to form a composite plate having a thickness of 1 mm. The composite plate and a steel backing metal having a thickness of 2 mm were superposed. The resultant was roll-pressed to obtain a 1.65 mm-thick three-layer composite (bearing alloy layer + Al intermediate adhesive layer + steel back metal layer). The thickness of the bearing alloy layer at this time is 0.42 to 0.43 mm
The thickness of the Al intermediate layer was 0.02 to 0.03 mm, and the thickness of the steel back metal layer was 1.2 mm. The three-layer composite is pressed to obtain a semicircular bearing metal having a diameter of 53 mm and a length of 17 mm (or a surface layer is coated on the surface of the bearing alloy by electroplating in a known fluorinated bath. Thus, a four-layer composite having a surface layer having a thickness of 20 μm was obtained, and these were used for a baking test and a fatigue test. Figure 1,
FIG. 2 shows an enlarged sectional view of the three-layer and four-layer bearing metals.
1 is a steel backing metal layer, 2 is an Al adhesive layer, 3 is a bearing alloy layer, and 4 is a surface layer. Table 3 shows the conditions of the fatigue test, and Table 4 shows the conditions of the seizure test. Table 5 shows the results of the fatigue test, and Table 6 shows the results of the seizure test.

である。The present invention has the following excellent effects. (1) From the fatigue test results in Table 5, it can be seen that all bearings of the present invention have improved fatigue strength as compared with conventional bearings.
This is achieved by adding Bi and alloying with Sn.
It can be said that the hardness of the layer increases, which contributes to the improvement of the fatigue strength. Conventionally, Al bearing alloys containing high Sn are:
Fatigue strength tended to decrease due to the large amount of Sn. However, this could be suppressed by adding Bi as in the present invention. (2) The seizure test results in Table 6 show that all bearings of the present invention have improved non-seizure properties as compared to conventional bearings.
This is because the added Bi alloyed with Sn to improve the lubrication characteristics of Sn. (3) From the above test results, the bearing of the present invention has improved fatigue strength and seizure performance as compared with the conventional bearing. (4) Therefore, the product of the present invention can achieve the initial purpose. In other words, the present invention can be applied to recent large-size engine bearing metals that require higher fatigue strength and non-seizure properties.
