関する。Description: TECHNICAL FIELD The present invention relates to a surface treatment structure in a plain bearing device used for supporting a crankshaft or the like in an internal combustion engine or the like.

金属軸受層と丁度良い状態で接触させようとするもので
ある。A sliding bearing device used for supporting a crankshaft or the like of an internal combustion engine, the metal bearing layer formed on a back metal with a metal material such as an aluminum alloy that is relatively resistant to wear,
There is one in which a bearing surface layer made of a flexible material such as lead or tin is formed on the metal bearing layer. The bearing surface layer is intended to be brought into contact with the metal bearing layer in the middle in an exactly good state because the portion which is strongly contacted with the bearing surface is worn in the process of use after mounting the rotary shaft.

することはなく、荷重に均等に分散させ、耐久性を向上
させることができる。However, depending on the contact state with the rotating shaft, the bearing surface layer is locally extremely greatly deformed and worn, and locally concentrated contact with the metal bearing layer may occur, which may cause a large resistance. Therefore, Japanese Patent Application Laid-Open No. 60-205014 proposes a metal bearing layer in the middle of which ridges and grooves having a predetermined depth are formed in an uneven shape. When the surface layer of the shaft bearing is worn after the mounting of the rotary shaft, the rotary shaft contacts at the tips of the scratches in the metal bearing layer, and the contact points can be evenly distributed over the length direction of the bearing. Therefore, the load is not locally concentrated, and the load can be evenly distributed to improve the durability.

間抵抗（フリクション）が大きい欠点がある。After assembling the bearing to the rotating shaft, the bearing surface layer wears,
There is a drawback that it takes time until the state supported by the metal bearing layer is obtained (that is, until complete conformity is obtained), and during that period, the resistance (friction) is large.

によって前記の課題の解決を図るものである。According to the present invention, the bearing surface layer is deformed and abraded early in a portion where a load applied from the rotary shaft is high, so that the rotary shaft and the bearing quickly become familiar with each other, and the support state by the metal bearing layer is established early. By devising the structure as described above, the above problem is solved.

In a plain bearing in which a concave-convex streak of a predetermined depth is formed in the longitudinal direction of the bearing at a boundary surface with the layer, the pitch of the concave-convex is large at a place where a load applied to the bearing is high. Will be provided.

なじみが得られる。With the rotary shaft assembled to the bearing, the metal bearing layer where the load from the rotary shaft is high has a large pitch of the scratches, and the amount of the bearing surface layer formed on it is the same as the amount of the metal bearing layer. As a result, the soft bearing surface layer in a portion having a high load is rapidly deformed and abraded, resulting in early contact with the metal bearing layer below the soft bearing surface layer. Therefore, quick familiarization can be obtained.

The difference is that in this embodiment, since the rotary shaft 24 is inclined with respect to the axial direction, the load on one end of the upper half portion 20 is large and the load on the opposite end of the lower half portion 22 is large. . The basic structure of the surface layer is the same, but to distinguish it from the previous examples,

The rear end portion of b and the front end portion of the bearing surface layer 14b ′ of the lower bearing 22 are worn, and the tip end portion of the surface of the scratches of the metal bearing layers 12b and 12b ′ comes into contact with the rotating shaft 24 in an ideal state. Shows after reaching. Since the streak pitch is large where the load is large, this load causes the ends of the bearing surface layers 14b, 14b 'to deform and wear quickly, so that the metal bearing layers 12b, 12b' are better suited. A good support state is obtained.

成されている。FIG. 3 (A) shows a state before use of the third embodiment of the sliding bearing device of the present invention. In this embodiment, it is assumed that the rotating shaft has a curved shape in an operating state. Therefore, the central part of the lower bearing 22 and the upper bearing 20
It is assumed that both ends will be unbalanced. In order to distinguish it from the previous embodiment, the suffix c is added.
The surface layer of the upper portion 20 is the metal bearing layer as in FIG.
The metal bearing layer 12c is provided with a concave-convex streak, which includes a bearing surface layer 14c and an intermediate layer 16c. Similarly, the surface layer of the lower portion 22 has a metal bearing layer 12c 'and a bearing surface layer 14c'.
And the intermediate layer 16c ', and the metal bearing layer 12c' is provided with uneven scratches. According to this embodiment, the striation pitches at both ends of the upper bearing portion 20 are longer than the striation pitches at the central portion, and the lower bearing portion 22 has the striation pitches at the central portion at the striation pitches at both ends. It's getting longer. Then, in the portion having a large pitch, not only the pitch of the striations but also the depth thereof is deeper than the outer portion in accordance with the bending of the shaft 24.

Both end portions of c and the middle portion of the bearing surface layer 14c 'of the lower bearing 22 are worn, and the tip end portion of the surface of the striations is the metal bearing layers 12c and 12c.
It shows after reaching the ideal state of contacting the tip of the streak of c '. Since the streak pitch is large where the load is large, this load causes the ends of the bearing surface layers 14c, 14c 'to be deformed and worn out quickly so that they can fit quickly and are better than the metal bearing layers 12c, 12c'. A good support state is obtained. In addition, since the depth of the striations on one side of the shaft 24 is increased according to the bending of the shaft 24, a sufficient depth of the striations can be obtained regardless of the bending of the shaft 24.

ことでフリクションが大きい期間の短縮を実現すること
ができる効果がある。According to the present invention, the unevenness formed on the surface of the metal bearing layer has a large pitch at a place where the load is high. Therefore, in a high load area, the amount of the bearing surface layer made of a flexible material is relatively large compared to the amount of the metal bearing layer, so that this area is rapidly deformed and worn by the rotating shaft, and the shaft becomes a metal bearing. A familiar state in which the layers are supported can be quickly reached, and the rotational axis can be quickly made to fit in, so that a period in which friction is large can be shortened.
