Claims

[Scope of utility model registration request]

The thrust bearings are housed in an oil tank and are arranged in a radial direction between a plurality of thrust pads of a thrust bearing that rotatably supports a thrust runner of a rotating shaft from below,
The high-temperature lubricating oil that lubricates the bearing surface of the thrust pad and flows along with the thrust runner is received on the lower surface side of the thrust runner and directed downward, and the centrifugal pump means is formed on the inner circumferential side of the thrust runner. In an oil scrubbing device for a thrust bearing of a vertical shaft rotating electric machine, which is induced by pressure, a plurality of support columns arranged in a radial direction and fixed to a support plate attached to the bottom side of the oil tank, and a bottom friction A radial can holder made of modulus material and provided at the top of these support columns is supported across the groove, and an oil-scraped plate whose upper end contacts the lower surface of the thrust runner, and a radial can plate below this oil-scraped plate. a vertical partition plate disposed in the direction and partitioning both thrust pads into two in the circumferential direction, and a partition plate disposed at the lower end position of the third partition plate forming the bottom;
These partition plates and the side surface of one of the thrust pads form a radial outlet path, and the high-temperature lubricating oil received by the oil scraper plate is introduced into the outlet path and is radially released. A scrubbing device for a thrust bearing of a vertical shaft rotating electric machine, characterized in that the oil is guided to the inner circumferential side of the thrust runner.
