Claims

[Scope of utility model registration request]

The thrust bearing is housed in an oil tank and rotatably supports the thrust runner of the rotating shaft from below, and is disposed between a plurality of thrust pads in the half-U direction, respectively;
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 on a support plate attached to the bottom side of the oil tank, It is supported so as to be able to move up and down across radial support grooves provided at the top of the support column, and is pressed upward by a compression spring fitted at the bottom. A guide path is provided in the radial direction, and the guide path communicates with the groove. An oil scraper plate is provided that is in pressure contact with the lower surface of the thrust runner and is tilted in the direction of rotation. An oil scrubbing device for a thrust bearing of a vertical shaft rotating electrical machine, characterized in that it is introduced into a guide path and guided to the inner circumferential side of the thrust runner.
