この考案は、回転電機のすべり軸受装置、特に
その油カキの構成に関するものである。[Detailed Description of the Invention] This invention relates to a sliding bearing device for a rotating electrical machine, and particularly to the structure of its oil oyster.

なつている。 Conventionally, the structure of this type of oil oyster is shown in FIGS. 1, 2, and 3. That is, in Figs. 1 to 3, 1 is the rotating shaft, 2 is the thrust collar,
3 is an oil tank storing oil 4, and 5 is the thrust collar 2 mentioned above.
A pad 6 which is arranged around the rotating shaft 1 so as to be in sliding contact with the lower end of the pad 6 and which receives the load of the thrust collar.
An oil oyster is placed between these pads, and this oil oyster has a structure in which the shoe 7 is held between the two and pressing plates 8, 8 are brought into contact with both sides of the shoe 7, and these are held together by rivets 9.
次に動作について説明する。回転部はスラスト
カラ２を介してパツド５の上をすべり回転する。
そしてこのとき油カキ６が回転面を摺動すること

除くものである。 Next, the operation will be explained. The rotating part slides and rotates on the pad 5 via the thrust collar 2.
At this time, the oil oyster 6 slides on the rotating surface to remove the high temperature oil film attached to the thrust collar surface.
従来の油カキは以上のように構成されているの
で、構造が複雑であるとともに、大型化し、パツ
ド間の距離の小さい小型機では、却つてパツド間
の半径方向外向きの油流をじやまして油カキの効
果を殺していた。 Conventional oil oysters are constructed as described above, so they have a complex structure and are large in size.In a small machine with a small distance between the pads, it is difficult to prevent oil flow outward in the radial direction between the pads. Moreover, it was killing the effect of oil oysters.
この考案は上記のような従来のものの欠点を除
去するためになされたもので、油カキの構造を簡
素化して小型にし、かつ油流をじやますることな

る。 This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above, and it simplified the structure of the oil oyster and made it smaller, and it was able to fully demonstrate its effect without hindering the flow of oil. It is something.
以下この考案の一実施例を第４図について説明

い。 An embodiment of this invention will be described below with reference to FIG. That is, FIG. 4 is a perspective view showing the structure of the oil oyster 10 according to the present invention, in which a flat presser plate 11 is shown.
The shoe 12, which becomes the sliding contact part with the thrust collar, is cast in or attached by pressure welding.
The oil oyster 10 is installed in place of the conventional oil oyster 6 mentioned above. The material of the shoe 12 may be a bearing alloy or a material similar to Teflon.
このように構成された油カキは、コンパクトで
薄いためパツド間のスペースが狭い機械にも取付
けることができ、又余分な突起物が無いため半径

は、台板１１にシユー１２を鋳込んだものを示し
たが、シユーのみの一体構造とすることも可能で
ある。 The oil oyster constructed in this way is compact and thin, so it can be installed in machines with narrow spaces between pads, and since there are no extra protrusions, the oil oyster can be installed without impeding the radial oil flow. can fully demonstrate its effects. In the above embodiment, the shoe 12 is cast into the base plate 11, but it is also possible to have an integral structure with only the shoe.
以上のようにこの考案によれば、従来の挾み込
み構造のものから、一枚ものの一体構造としたの
で、部品数が減り、安価かつ簡素化できるととも
に、従来の如く半径方向の油流をじやますること

ものを提供し得る。 As described above, according to this invention, the conventional wedge-in structure is replaced with a one-piece, integral structure, which reduces the number of parts, makes it cheaper and simpler, and prevents oil flow in the radial direction as before. To provide a highly reliable product that can fully demonstrate the functions of oil oysters without causing discomfort.

Figure 1 is a cross-sectional side view of the oil oyster part of a conventional rotating electric machine, Figure 2 is a plan view taken along the - line in Figure 1, Figure 3 is an exploded view of the conventional oil oyster, and Figure 4 is this invention. FIG. 2 is a perspective view showing one embodiment of the invention. In the figure, 1 is the rotating shaft, 2 is the thrust collar, 3 is the oil tank, 5 is the pad, 10 is the oil oyster, 11 is the base plate, 1
