PURPOSE:To eliminate the leakage of oil with a simple sealng structure at the guide bearing device for a vertical shaft rotary electic machine by providing special relationships among the outer diameters of an inner plate in an oil tank, of the shaft end flange of a rotational shaft and the inner diameter of a bottom plate of the tank. CONSTITUTION:There are provided an oil tank formed to surround a rotational shaft 1 and a guide bearing shoe 3 sliding with the journal 2 of the shaft 1, and lubricating oil is contained in the oil tank. The oil tank for the guide bearing device is formed of a bracket 4 mouned with the shoe 3, an inner plate 5 of the tank provided along the shaft 1, and a bottom plate 6 of the tank for connecting the bracket 4 to the plate 5. The outer diameter D4 of the plate 5 is formed smaller than the inner diameter D2 of the bracket 4 and larger than the outer diameter D1 of the shaft end flange 11 of the shaft 1, and the inner diameter D3 of the plate 6 is formed at a value larger than the outer diameter D1 of the flange 11. |
