Description of the Related Art There are various types of sliding bearings that have been conventionally used, but recently, a back metal is lined with a porous sintered metal, and a lubricous plastic material or the like is lined here. The impregnated material is used as a bush or the like. Such bearings are unlubricated bearings that do not require lubrication and are generally called depleted lubricated bearings or dry bearings.

化合物を添加したものなどが使用されている。In general, ordinary steel is used for the back metal of these depleted lubrication bearings, and bronze or white metal copper-based materials are used as the sintered metal. The reason why the above-mentioned materials are selected as the sintered metal is that these metal materials themselves have lubricity and that the sintering process is easy. Further, as the lubricious plastic material, tetrafluoroethylene (polytetrafluoroethylene-PTFE), a material obtained by adding a tin- or lead-based compound to this PTFE, or the like is used.

されている。Further, as a manufacturing method, the following method is generally used. First of all, sintered metal powder is sprinkled from a hopper on a strip-shaped backing steel plate and ground into a certain thickness by the well-known doctor blade method, which is continuously sintered in a heating furnace to form a porous sintered body. A steel strip lined with metal is obtained. After that, the porous sintered metal layer is impregnated with plastic by a roller or the like and fired. After that, cold rolling or the like is performed to finish the shape and the like. Such bearing materials are
After that, it is subjected to various molding processes and is currently used as a bearing for various engines, electric motors, compressors, pumps, turbines and other devices. Also, a stainless steel plate is used to improve the corrosion resistance of the backing metal, and a mixture of stainless steel powder and Cu-Mn-based powder or Ni-Mn-based powder is used as the material of the sintered metal, which is disclosed in JP-A-61-35241.

とする用途には使いにくいという課題があった。Since the conventional corrosion-resistant steel sheet for dry bearing is constituted as described above, the following problems exist. That is, such a dry bearing is generally cleaner than a normal bearing using oil or the like. However, medical equipment and food-related equipment are often exposed to a moist atmosphere with various chemicals and edible materials, etc. Complete corrosion resistance is required. The conventional dry bearing has a problem that it is difficult to use in applications requiring strict corrosion resistance because not only the back metal using ordinary steel but also the porous sintered metal layer cannot escape corrosion.

It has been requested.

もあった。Further, regarding the method of spraying the metal powder on the backing metal (layer height) with a doctor blade and sintering this, the thickness of the porous sintered metal layer tends to vary. However, such a thickness variation is not preferable, although it may be finally finished by cutting or the like. Also, the strength of the porous layer largely depends on the proportion of the voids, but the method of spraying the metal powder on the backing metal by free fall is almost equal to the method of controlling this, so the proportion of the voids is changed. There was also a problem in that it had to rely on changing the shape and size of the powder.

By passing between the rollers 14 of the book, the sintered plate 10
Of the above-mentioned PTFE was impregnated into the porous sintered layer of
It was baked in the air at 50 ° C. A plate-shaped test piece was cut from the thus-obtained dry bearing steel plate 12 and the impregnation depth of the resin (PTFE) was measured. A salt spray test was also conducted to investigate the corrosion resistance. The salt spray test is JIS-Z-
2371, and the test time was 24 hours.
As a comparison of corrosion resistance, a bush made of a material obtained by sintering conventional bronze powder on a plain steel plate was also subjected to a salt spray test.

分があり歩留が低下する状態にあった。The above-mentioned test results are summarized in Table 3 of Table 3 below. The impregnation depth increased as the porosity increased.
It can be seen that the lubricity generally increases as the impregnation depth increases in dry bearings. On the other hand, when the porosity was 53%, the impregnation depth was large, but there was a portion where minute cracks were generated during handling of the powder rolling-sintering-laminating step, and the yield was in a state of being reduced.

The depth of impregnation is smaller than that of the one having a large particle diameter, and the one having a relatively large particle diameter of about 30 to 60 mesh is preferable for facilitating the impregnation. There was found.

た。Further, in the salt spray corrosion test, in the ordinary bearing of the comparative material, red rust was remarkably observed in the back metal part and blue rust was remarkably observed in the porous sintered layer.
No rusting was observed in any of the steel sheets according to the present invention.

It is general to use an austenitic stainless steel plate such as 04 or a ferritic stainless steel plate such as SUS430. The stainless steel powder 1 to be subjected to powder rolling is the same as the backing metal, and its kind is not particularly limited, but it is generally SU.
S304 or the like is used.

さの減少等が生じる。The particle size of the above-mentioned stainless steel powder 1 affects the size of voids in the sintered plate 10 and, in turn, the difficulty of impregnation. Therefore, depending on the strength of the sintered plate 10 and the degree of impregnation. It may be appropriately selected, but from the viewpoint of facilitating the impregnation, powder of 30 to 60 mesh is preferable. That is, if the coarse powder is less than 30 mesh, it is difficult to form the powder by powder rolling, and if the powder is more than 60 mesh, the size of the void is not sufficient, so that the depth of impregnation is reduced.

The void particle size at that time also affects the difficulty of impregnation, and the higher the porosity, the deeper the impregnation depth. Is increased. Therefore, in reality, the porosity is 25%.
The above is preferable, but if the porosity exceeds 50%, the strength of the molding strip during powder rolling becomes excessively low.
The following is preferable.

を勘案しながら接合する必要がある。As for the method of laminating the sintered plate 10 having the porous sintered layer and the stainless steel plate 11, as described above, there is no problem in corrosion resistance and the strength required as the bonding strength with the back metal is satisfied. It is not particularly limited as long as it can be applied, and as a method of this bonding, a method of partially joining by spot welding, a method of heating the joining surface while applying pressure and performing diffusion joining between solids, There is a method of heating in an active atmosphere and hot rolling under a comparatively light pressure to join as a rolled clad. In these joinings, if excessive reduction is applied, the voids in the porous sintered layer will be crushed and impregnation cannot be performed sufficiently. Therefore, it is necessary to take this point into consideration when joining.

In addition to being excellent in corrosion resistance as compared with the ones, by making the porous sintered layer into a molded body by powder rolling, it becomes excellent in dimensional accuracy and the like. The present invention is intended for dry bearings that use a lubricant such as plastic, but is also effective for oil-impregnated bearings that use a porous sintered layer.
