体を持上げることが必要になる。 In the conventional rotor mentioned above, for example, in the case of a water turbine generator, inspection of the water turbine parts directly connected to the lower part,
For disassembly, inspection, adjustment, and disassembly of generator bearings, it becomes necessary to lift the entire rotor without disassembling the entire generator.

ていた。 In the conventional rotor described above, in order to fix the spider rim 3 to each support plate part 2b in the circumferential direction and radial direction, a connecting key 6 fixed by a shrink fit or a spring member is inserted between the two parts. but,
When pushing up and down the spider rim 3 with the jack 11, if a misalignment occurs in the axial direction between the spider rim 3 and the support plate portion 2b, the connecting key 6 may seize or the magnetic center line between the pole core 9 and the stator core may become misaligned. This will impede smooth operation. For this reason, an adjustment liner 8 or 15 is inserted between the presser key 7 or the support plate 13 and the upper end of the spider rim 3 to prevent a gap, but this is a cumbersome and time-consuming process. However, in reality, Spiderlimb 3
There is an error in the lamination length of the rim, and there are deviations and undulations in the thickness of the rim thin steel plate, making it difficult to adjust the liner to eliminate gaps at all locations. For this reason, it was not possible to completely eliminate the gap. Furthermore, fixing the adjustment liners 8, 15 to prevent them from flying out due to centrifugal force requires a great deal of labor and work time.

的としている。 This idea is to attach a supporting metal fitting to the lower end of the spider rim's tightening bolt, and to press the lower end of the spider's support plate part with the inner upper surface of this supporting metal fitting. The purpose of the present invention is to provide a rotor for a vertical shaft rotating electric machine which eliminates axial misalignment between the spider and the support plate part of the spider, eliminates the need for a conventional adjustment liner, and facilitates assembly work and shortens the time.

7, 9 to 12 are the same as those of the conventional device described above, and the explanation thereof will be omitted. A rotor spider 20 is directly connected to the rotating shaft 1, and has a plurality of radially extending arms 2.
Support plate portions 20b are axially welded and fixed to the distal end portions of Oa, respectively. A protruding part 20c extending in the radial direction is provided at the lower part of each support plate part 20b, and receives the lower end of the spider rim 3, and a notch part 20d is formed at the lower end. A tightening bolt 21 passes through the inner circumferential side of the spider rim 3 and is tightened by upper and lower nuts 5, and the lower end portion thereof is longer than the other tightening bolts 4. Reference numeral 22 designates a plurality of supporting metal fittings that are passed through the lower end of the tightening bolt 21, tightened with nuts 5, and fixed to the inner diameter side of the lower end surface of the spider rim 3, and the inner upper surface holds down the notch 20d of the support plate portion 20b from below. I'm wearing it.

を生じることなく、一体的に押上げ下げされる。 In the rotor according to the embodiment described above, when the spider rim 3 is pushed up by each jack 11, each support plate portion 20b is simultaneously pushed up by the same amount via each support fitting 22. Therefore, the rotor spider 20, the rotating shaft 1, and the rotating part on the water turbine side are also lifted up together. The protruding part 20c of each support plate part 20b is sandwiched between the inner diameter side of the lower end surface of the spider rim 3 and the inner upper surface of the support metal fitting 22, so that even if there is a gap between the presser key 7 and the upper end of the spider rim 3, the spider rim 3 The rotor spider 20 and the rotor spider 20 are pushed up and down as one unit without any deviation in the axial direction.
