1 and 2 show a conventional example of a thrust bearing device for a vertical shaft water turbine generator. As shown in the figure, a runner 2 is fixed to the rotating shaft 1, and the runner 2 slides and rotates via an oil film on a plurality of bearing shoes 3 arranged at equal intervals in the circumferential direction. ing. The support 4 at the bottom of these bearing shoes 3 connects to the bracket 5 at the bottom of the bearing oil tank.
It is swingably supported by an arcuate surface 7 of a pivot 6 projecting upward, and the snust load due to the weight of the rotor 8 of the generator, etc. is transmitted from the bracket 5 to the foundation. The bearing shoe 3 is also connected to the bracket 5.
Movement in the horizontal direction is restrained by a frame 10 fixed to the upper support seat 9 and an annular plate 11.

とができる。 If the bearing shoe 3 in the thrust bearing device configured in this way is burnt out, it must be disassembled and inspected or replaced.
When disassembling the bearing shoe 3, it takes a great deal of effort and time to disassemble the rotor 8, rotating shaft 1, runner 2, etc. that are disposed above the bearing shoe 3. For this reason, an annular plate 11 is provided so that the bearing shoe 3 can be disassembled without disassembling the rotor 8, rotating shaft 1, runner 2, etc. That is, the rotor 8 is raised by the jack 12 and a gap of about 5 mm is provided between the runner 2 and the bearing shoe 3 to eliminate the load on the bearing shoe 3. Next, the two-part annular plate 11 that restricts the movement of the bearing shoe 3 is removed. By doing this, the upper surface of the frame 10 is configured to be located below the lower surface of the support 4, so that the bearing shoe 3 can be taken out in the horizontal direction together with the integrated support 4. Then, it can be taken out of the machine through the disassembly window 13 of the bracket 5 on the side of the bearing oil tank.

の欠点があつた。 However, such a thrust bearing device requires the same number of pair of annular plates 11 as the number of bearing shoes 3, which requires a lot of man-hours to manufacture, and since there are many, it takes a lot of time to remove them. There were some drawbacks, such as the need for

That is, the present invention fastens and supports the frame to the support seat via a removable constant piece, and the size of the constant piece is determined such that when the constant piece is removed, the upper surface of the frame is in contact with the bearing shoe. It is designed to achieve its intended purpose by forming it in a size that is lower than the bottom surface.

The present invention will be described below based on illustrated embodiments. FIG. 3 shows an embodiment of the invention. Note that parts that are the same as those in the prior art are designated by the same reference numerals, and therefore their explanations will be omitted. In this embodiment, frame 10
a is supported by the support seat 9 via the constant piece 14. The constant piece is removed when the bearing shoe is disassembled, and its size is such that the upper surface of the frame 10a will be at a lower position than the lower surface of the bearing shoe 3 when the constant piece is removed. has been done. By doing so, the bearing shoe 3 can be moved in the horizontal direction by removing the constant piece 14, and a thrust bearing device in which the bearing shoe 3 can be easily disassembled and inspected can be obtained.

業においても取り外しの時間が少なく、従来に比
べて作業工程を短縮することができる。 That is, the frame 10a is removably fastened to the support seat 9 via the constant piece 14 with the bolt 15, but the thickness of the constant piece 14 is set so that the support 4 restrains the movement of the bearing shoe 3 in the horizontal direction. The lower surface of the frame 10a and the support seat 9 are
The distance H 1 between the top surface and the top surface is set so that H 1 > H 2 . That is, the constant piece 14 is set to a size such that the upper surface of the frame 10a is located at a lower position than the lower surface of the bearing shoe 3 when the constant piece 14 is removed. By doing this, when the constant piece 14 is removed and the frame 10a is lowered onto the support seat 9 as shown in FIG. 4, the upper surface of the frame 10a will be lower than the lower surface of the support 4. Therefore, the bearing shoe 3 can be taken out in the horizontal direction together with the integrated support 4 as shown by the solid arrow in the figure, and can be taken out of the machine through the disassembly window 13. It goes without saying that in this case, prior to removing the constant piece 14, the rotor 8 is raised by the jack 12 so that the bearing shoe 3 is placed in an unloaded state. This constant piece 14 has a much simpler structure than the conventional two-part annular plate 11, and the number of the constant pieces 14 can be the same as the number of support seats 9 (see Fig. 2), which are about half of the bearing shoes. The number of parts is greatly reduced, and therefore the removal time during disassembly work is shortened, making it possible to shorten the work process compared to the conventional method.
