3 to 5 show conventional examples of a disassembly device for a thrust bearing in a vertical shaft water turbine generator or the like. As shown in the figure, a beam-shaped bearing slide 2 is inserted into the lower surface of the bearing 3 through the carrying port 1, which is made up of an inspection window 1a and a cover 1b provided on the side wall of the oil tank. A device is used that slides on a sliding table 2 and pulls out the oil tank to the outside, but this has the disadvantage that it cannot be used when there is an oil cooler inside the oil tank. In the figure, 4 is a main shaft, 5 is a bracket, 6 is a jack, 7 is a runner, 8 is a bearing frame, and 9 and 10 are support beams.

する欠点があつた。 As a countermeasure for this, there is a device that lowers the bearing device and disassembles it, but this device uses multiple screw jacks (not shown) on the bottom surface of the bearing device to operate the bearing device when lowering it. As a result, the lifting speed was slow and the work required a lot of time.

案されている。 In order to improve this, as shown in Figure 1, multiple bearings (usually 3) are used for lifting and lowering the bearing device.
L-shaped hanging beam 11 and chain block 12
By using a bearing device of In addition, the trolley chain block 13 only needs to be attached and removed once, and furthermore, the trolley chain block 13 can be carried on the trolley by means of the rails 14 installed in the radial direction at predetermined positions and the carrying port 16 provided in the foundation 15. It has been proposed that the bearing 3 can be transported outside the machine in an extremely short time by moving the bearing 17.

Supported. The bearing 3 is disposed on the bearing frame 8, and has a coupling flange 19 at its lower part, and is configured to support the rotating main shaft 4, rotor 20, runner 7, etc. 3 is burnt out, first three L-shaped hanging beams 11 are arranged at approximately equal intervals on the circumference and attached to the bearing frame 8, and then the hooks 21 installed on the bracket 5 and the hanging beams are attached to the bearing frame 8. Hang the chain block 12 on the hook 22 installed on the jack 6.
Then, the rotor 20 is slightly lifted, and in this lifted state, the chain block 12 is operated to slightly lift the bearing frame 8. Rotor 20 is jack 6
Since the chain block 12 is supported by the chain block 12, it is only necessary to lift relatively lightweight parts such as the bearing frame 8 and the bearing 3. With this bearing frame 8 lifted, remove the key 18, and then remove the chain block 1.
2 to suspend the bearing frame 8 above the support device 23. Then, the support beam 24 and the annular rail 25 are arranged on the bracket 5, and the trolley chain block 13 is attached to the annular rail 25.
On the other hand, the hanging fitting 26 and the wire rope 27 are attached to the bearing 3, and the trolley chain block 13 is attached.
to lift the bearing 3. In this state, rail 1
4 is attached between the bearing frame 8 and the foundation 15, a trolley 17 is placed on this rail 14, the bearing 3 is suspended on the trolley 17, and the bearing 3 is removed from the machine through the carrying port 16 by pulling the trolley 17. I tried to get it out in a short time. In addition, in the figure, 28 is an oil dam, and 29 is a water turbine main shaft.

を下方へ下げないで分解していた。 By the way, when disassembling the bearing 3 like this, if the distance H between the lower surface of the bracket 5 and the upper surface of the coupling flange 19 that protrudes radially from the main shaft 4 is not sufficiently large, it will be difficult to remove the bearing 3 from the machine. There is a drawback that the distance H1 between the upper surface of the bearing 3 and the lower surface of the bracket 5, which is a space, cannot be secured and disassembly is not possible.
It was disassembled without lowering it.

It is conceivable to move the position of the bracket 5 to a position where the distance H from the bottom surface of the bracket 5 is sufficiently large, but due to the structure of the power plant building or the structure of the water turbine directly connected to the bottom of the generator, In many cases, the H dimension could not be made sufficiently large.

That is, in the present invention, the inner diameter of the bearing frame is made larger than the outer diameter of the coupling flange, and the bearing frame is made such that the upper or lower surface of the coupling flange protrudes from the outer diameter of the coupling and is larger than the inner diameter of the bearing frame. The lower part of the bearing frame is supported below the top surface of the coupling using split support fittings arranged so that the thrust bearing can be disassembled to achieve the intended purpose. be.

The present invention will be explained below based on the illustrated embodiments. An embodiment of the invention is shown in FIGS. 6 and 7. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, the inner diameter of the bearing frame 8 (the inner diameter φ 2 of the lower disk 8c,
The inner diameter φ 3 ) of the upper disk 8b is made larger than the outer diameter φ 1 of the coupling flange 19, and the bearing frame 8 protrudes from the outer diameter φ 1 of the coupling 19 on the upper or lower surface of the coupling flange 19.
The bearing 3 was disassembled by supporting the lower part of the bearing frame 8 below the upper surface of the coupling using a split support fitting 31 arranged so as to have a larger inner diameter than the inner diameter of the bearing frame 8. By doing this, it becomes possible to disassemble by increasing the distance H 2 between the lower surface of the bracket 5 and the upper surface of the bearing 3, and it is possible to obtain a disassembly device for a vertical thrust bearing that is easy to disassemble. .

を得ることがきる。 That is, the inner diameter φ 2 of the lower disk 8c and the inner diameter φ 3 of the upper disk 8b of the bearing frame 8 are made larger than the outer diameter φ 1 of the coupling flange 19, and there is a gap between the oil dam 28 and the upper disk 8b in the circumferential direction. A connecting plate 30 divided into two parts was provided. In this way, the inner diameter φ 2 of the lower disc 8c of the bearing frame 8 and the upper disc 8b
Since the inner diameter φ 3 of each of the coupling flange 19 is made larger than the outer diameter φ 1 of the coupling flange 19, when the bearing device is lowered downward using the suspension beam 11 and the chain block 12, the bearing frame 8 is attached to the coupling flange 19. It will be possible to lower it below the top surface. A connecting plate 30 connects the upper disc 8b of the bearing frame 8 and the oil dam 28.
is divided in the circumferential direction and can be disassembled before lowering the bearing device downwards, so when the bearing device is lowered downward, it will not interfere with the coupling flange 19 and the bearing device will not interfere with the frame plate. Split type support fitting 31 fixed to the lower surface of 8a
This makes it possible to support the bearing 3 on the upper surface of the coupling flange 19, and the working space required to take out the bearing 3, that is, the distance H2 between the lower surface of the bracket 5 and the upper surface of the bearing 3, can be made larger than before. , it is possible to obtain a disassembly device in which the bearing 3 can be easily disassembled.

This is to limit movement in the circumferential direction and radial direction.

It was fixed to the lower surface and the lower surface of the coupling flange 19 with bolts 32 or the like. In this case as well, the distance H4 between the lower surface of the bracket 5 and the upper surface of the bearing 3 is made larger than before, and the bearing 3 can now be disassembled, and the same effects as in the above case can be achieved. .

As described above, the present invention makes the inner diameter of the bearing frame larger than the outer diameter of the coupling flange, and also makes the bearing frame protrude beyond the outer diameter of the coupling on the upper or lower surface of the coupling flange, and extends beyond the inner diameter of the bearing frame. Since the thrust bearing was disassembled, the lower part of the bearing frame was supported below the upper surface of the coupling using split support brackets arranged so that the upper surface of the thrust bearing and the lower surface of the bracket were larger. Since it becomes possible to disassemble the thrust bearing by increasing the distance between the two, the disassembly work of the thrust bearing becomes easy, and it is possible to obtain a disassembly device for a vertical shaft thrust bearing that is easy to disassemble.
