(1) Steel back metal layer Conventionally known and publicly used steel, such as general structural carbon steel specified by JIS, is used. (2) It is used to improve the adhesion between the intermediate layer steel backing metal and the bearing alloy layer, and it is made of conventionally known and publicly used pure Al, or when additional strength is required, Cu, Si, Mn, Zn, etc. are added as additive elements. An Al alloy to which a species or two or more species are added in a total amount of 0.1 to 2% by weight or less can be used. Further, when adding an additive element, if it is less than 0.1%, the addition effect is not obtained and it is meaningless, and if it exceeds 2%, it becomes brittle and is not suitable for practical use.

(b) Bi: 0.5-10% Bi alloys with Sn and improves the lubricating properties and conformability of Sn. Furthermore, when Bi is alloyed with Sn, the hardness of the Sn layer increases, which contributes to improving fatigue strength. Therefore, the fatigue strength is improved without changing the strength of the Al matrix, or in other words, without deteriorating the initial conformability. Also, if it is less than 0.5%, there is no effect of addition, and 10
If it exceeds %, the melting point will drop too much, causing problems in production. (c) Cu: 0.1-1.5% Cu improves the fatigue strength, which is a bearing property, and also improves the adhesive strength with the surface layer, but if it is less than 0.1%, the addition has no effect and 1 If it is added in excess of .5%, the alloy hardness becomes too large, resulting in poor initial conformability and embeddability. Moreover, since it inhibits ductility, it becomes difficult to manufacture. (d) Total amount of one or more of Ni, Si, Ag, Mg, Mn, Sb, and Zn: 5% or less Added and contained for the purpose of improving the mechanical strength of the Al matrix, and the total amount is 5% If it exceeds 5%, the initial conformability and embeddability deteriorate, so the upper limit was set at 5%.

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.

Tables 1 and 2 show the chemical components of the bearing alloy layer used in the bearing metal of the present invention and the conventional bearing alloy layer. The alloy plates with the compositions shown in Tables 1 and 2 and Al foil were stacked together and rolled together through a rolling mill to a thickness of 1 mm.
This composite plate and a steel backing metal layer with a thickness of 2mm are stacked together and then roll pressure bonded to form a three-layer composite with a thickness of 1.65mm (bearing alloy layer + Al intermediate adhesive layer + steel backing metal layer).
I got it. The thickness of the bearing alloy layer at this time is 0.42 to 0.4
3 mm, and the thickness of the Al intermediate layer is 0.02 to 0.03
mm, and the thickness of the steel back metal layer was 1.2 mm. This three-layer composite is pressed into a diameter of 53 mm and a length of 17 mm.
A semicircular bearing metal with a thickness of 20 μm is obtained (or a four-layer composite having a surface layer with a thickness of 20 μm is obtained by coating a surface layer on the bearing alloy surface by electroplating means in a known borofluoride bath) obtained) and used them for seizure tests and fatigue tests. Figures 1 and 2 show enlarged cross-sectional views of three-layer and four-layer bearing metal. 1 is a steel back metal layer, 2 is an Al adhesive layer, 3 is a bearing alloy layer, and 4 is a surface layer. Table 3 shows the fatigue test conditions, and Table 4 shows the seizure test conditions. Table 5 shows the results of the fatigue test, and Table 6 shows the results of the seizure test.

ものである。[Effects of the Invention] The present invention has the following excellent effects. (1) From the fatigue test results in Table 5, it can be seen that all the bearings of the present invention have improved fatigue strength compared to conventional bearings. This is achieved by adding Bi and alloying it with Sn.
This can be said to be because the hardness of the layer increases, which contributes to improved fatigue strength. Conventionally, Al bearing alloys containing high Sn are
The fatigue strength tended to decrease due to the large amount of Sn. However, by adding Bi as in the present invention, this could be suppressed. (2) From the seizure test results in Table 6, it can be seen that all the bearings of the present invention have improved anti-seizure properties compared to conventional bearings. This is because the added Bi alloyed with Sn and improved the lubricating properties of Sn. (3) From the above test results, the bearing of the present invention has improved both fatigue strength and seizure performance compared to conventional bearings. (4) Therefore, the product of the present invention can achieve the initial objective. That is, it can be applied to recent bearing metals for large engines that require better fatigue strength and anti-seizure properties.
