。That is, when the Al layer 2 made of the above-mentioned material with low high-temperature hardness is interposed between the back metal 1 and the Al-Sn bearing alloy layer 3 made of the above-mentioned material 1 with high high-temperature hardness, In this state, the Al layer 2, which has low high-temperature hardness, acts as a cushioning material for the Al-Sn bearing alloy layer 3, which has high high-temperature hardness, so that fatigue strength is improved. In addition, such an Al layer 2 has a one-sided contact of 1.11 (, j
In addition to improving heat dissipation of the Al-Sn bearing alloy layer 3, fatigue strength is also improved.

。The thickness of the Al layer 2 is from 5 μm to approximately the same thickness as the Al-Sn bearing alloy layer 3, that is, the Al layer 2 and the Al-
The thickness is preferably about 1/2 of the total thickness with the Sn-based bearing alloy layer 3. If it is too thin, the shock absorption and uneven impact absorption properties will be poor, while if it is thicker than the Al-Sn-based bearing base metal M3, the load capacity will be poor. As a result, seizure resistance and fatigue resistance are reduced.

This overlay layer 4, which is preferably made of a material containing at least 5 wt% of Sb, can be formed by chemical plating, electroplating, or dry spraying (sputtering, etc.), and is not necessary. If there is Al-
It is also possible to form old plating or Cu plating with a thickness of 4 to 5 gm or less on the Sn-based bearing alloy layer 3 as a base treatment, and then form on the plating.

性が改善される。The overlay layer 4 has excellent initial adaptability to shaft roughness, waviness, etc., and easily deforms, flows, and wears to adapt to uneven contact. In addition, it has excellent seizure resistance and is also good in embedding foreign matter. Furthermore, in order to ensure fluid oil lubrication conditions relatively early and to alleviate stress concentration caused by dust particles, etc., the fatigue resistance of the underlying Al-Sn bearing alloy layer 3 is also improved, and the overall seizure resistance as a bearing is improved. , fatigue properties are improved.

がては焼付に至るようになる。The thickness of the overlay layer 4 is preferably 1 to 30 gm,
The range of 3 to 104 m is more preferable. If it is too thin, the above-mentioned effect will be diminished, and if it is too thick, the fatigue strength of the overlay R4 itself will be poor, causing premature fatigue and oil film failure, which will eventually lead to seizure.

。Next, the coating layer 5 formed on the back surface of the backing metal 1 is coated with fretting wear that occurs between the backing metal 1 and a housing (not shown) that supports it, and the resulting accumulation of abrasion powder, or sludge caused by carbonization of lubricating oil. This coating layer 5 is intended to reduce deposits, etc. When the deposits grow, this coating layer 5 partially swells and creates a strong uneven contact state within the bearing surface, causing a concentrated load to occur in that area. It has the effect of preventing early fatigue failure.

Specifically, Cu, Ni, AI, alloys thereof, or synthetic resins such as PTFE, polyamide, and polyethylene can be used. Furthermore, Cu and Ni can be formed by electroplating or cladding, and Al can be formed by flash plating, cladding, or sputtering.

上が望ましく、厚すぎると軸受の耐久性が低下するので
、 １１００ｐ以下、望ましくは３０ｐｍ以下がよい。If the hardness of the coating layer 5 is less than 15 Hv, the effect will be reduced; on the other hand, if the hardness exceeds 80 Hv, it will not be possible to sufficiently bury the foreign matter interposed between the coating layer 5 and the housing, and localized A range of Hv 15 to 80 is desirable because a large swell occurs. Further, the thickness is desirably 0.31 tm or more in order to obtain a predetermined effect, but if it is too thick, the durability of the bearing decreases, so it is preferably 1100 p or less, preferably 30 pm or less.
なお、このコーティング層５は、必要に応じて省略して
