けられなかった。“Prior art and its problems” Various types of slide bearings are known. One of them is a type in which a cushioning resin material is sandwiched between the back metal and the bearing layer that is in sliding contact with the shaft. It has been known. The slide bearing having the cushioning resin material as an intermediate layer has an effect of absorbing the vibration acting on the bearing layer from the shaft and reducing the vibration. However, even this slide bearing having cushioning properties does not have sufficient flexibility for one-sided contact in which the slide bearing is relatively inclined with respect to the shaft, and when one-sided contact occurs for some reason, uneven wear, abnormal noise, etc. occur. It was unavoidable to do.

摩耗や異音が生じにくくなる。[Summary of the Invention] The present invention focuses on the fact that a sliding bearing generally has an oil groove in the circumferential direction formed on the sliding contact surface with the shaft, and the bearing layer is divided in the axial direction by this oil groove. This improves the flexibility for one-sided contact. That is, the sliding bearing of the present invention is characterized in that the circumferential oil groove formed on the inner surface is formed at least to a depth reaching the cushioning viscoelastic resin layer from the bearing layer. According to this plain bearing, the bearing layer is divided in the axial direction of the plain bearing, and the viscoelastic resin layer for cushioning makes it possible to deform each independently, resulting in higher flexibility for one-sided contact and uneven wear. Noise is less likely to occur.

ある。"Examples of the Invention" The present invention will be described below with reference to illustrated examples. 1 to 3 show an embodiment of a plain bearing 10 according to the present invention, and the features of the present invention appear in the sectional view of FIG. That is, the sliding bearing 10 of the present invention is a sliding bearing in which a cushioning viscoelastic resin layer 12 is bonded to the inner surface of a back metal 11a, and a bearing layer 13 is bonded to the inner surface of the back metal 11b via a back metal 11b. An oil groove in the circumferential direction is formed on the inner surface of the slide bearing 10.
The feature is that the oil groove 14 is formed and the depth of the oil groove 14 is at least the depth reaching the viscoelastic resin layer 12 from the bearing layer 13.

Setting the groove depth makes it easier to set the groove depth. 15 is an oil groove

である。The backing 11 is generally made of steel, but the present invention does not matter. The viscoelastic resin layer 12 may be of any type as long as it is a resin material having a cushioning property and is excellent in the bondability with the back metal 11 and the bearing layer 13. As the resin material, a plate material known as a vibration-damping steel plate, that is, the same resin material as the plate material in which a viscoelastic viscoelastic resin material having a vibration absorbing property is interposed between the steel plates can be used. Further, the thickness of the viscoelastic resin layer 12 is set to a thickness capable of achieving the purpose of vibration absorption, for example, 30 to 200 μm as described above. By the way, the thicknesses of the backing plates 11a and 11b and the bearing layer 13 are usually 0.5 to 5 mm, 0.1 to 1 mm, and 0.5 to 3 mm, respectively.
軸受層13は、裏金11および樹脂層12と同様に、あるい
はそれ以上に、その構造例が多い。本発明は、この軸受
層13の構造、材質もまた問わない。この軸受層13には、
ケルメット、アルミ合金、あるいは合成樹脂被膜等を用
いたもの等がある。The bearing layer 13 has many structural examples similar to the backing metal 11 and the resin layer 12 or more. In the present invention, the structure and material of the bearing layer 13 are also not limited. In this bearing layer 13,
There are those using kelmet, aluminum alloy, or synthetic resin coating.
またすべり軸受10の構造としては、裏金11bを省略し

の内面に軸受層13を配したものであってもよい。The sliding bearing 10 may have a structure in which the backing metal 11b is omitted, the resin layer 12 is directly bonded to the inner surface of the backing metal 11a, and the bearing layer 13 is disposed on the inner surface.

受層13が分断されていない場合を想定すると明らかであ
る。The plain bearing 10 of the present invention has a bearing layer 21 formed by the oil groove 14.
3 is axially divided into a left bearing layer 13a and a right bearing layer 13b. Therefore, the left bearing layer 13a and the right bearing layer 13b can be independently displaced with respect to the back metal 11a within the range of elasticity and cushioning property of the viscoelastic resin layer 12. That is, as shown by the chain line in FIG. 1, when the axis of the shaft 16 and the axis of the main slide bearing 10 are tilted or bent, the left bearing layer 13a and the right bearing layer 13b are
Will follow this inclination and so on. This good followability is clear assuming that the bearing layer 13 is not divided.
つまり軸16と軸受層13の軸線が傾いた場合、軸受層13

わち本発明は、軸受層13に関しては、短い左軸受層13a
と右軸受層13bを並べたのに相当するから、変形が容易
であり、片当りに対する柔軟性が高いのである。That is, if the axes of the shaft 16 and the bearing layer 13 are tilted, the bearing layer 13
The two ends of the one end try to approach the back metal 11a on the one hand, and try to separate from the back metal 11a on the other hand. Obviously, this deformation becomes easier as the axial length of the bearing layer 13 becomes shorter and the deformation allowable amount of the viscoelastic resin layer 12 becomes larger.
Since there is a limit to the deformation allowable amount, it is understood that the shorter the axial length of the bearing layer 13, the easier the deformation. That is, the present invention relates to the bearing layer 13 that is a short left bearing layer 13a.
Since this is equivalent to arranging the right bearing layer 13b and the right bearing layer 13b, the deformation is easy and the flexibility for one-sided contact is high.

タイプのすべり軸受にも成立する。In the illustrated example, the number of oil grooves 14 is one, but the present invention is of course applicable when two or more oil grooves 14 are formed. Further, the present invention is applicable to an all-cylindrical bush type sliding bearing in addition to the illustrated two-split type sliding bearing.

Therefore, it is possible to reduce uneven wear and noise. Further, in relation to the normal shaft, the intermediate layer exerts its original vibration absorbing action and noise reducing action, so that the basic properties of these intermediate layers are not impaired.
