Abstract

PURPOSE:To prevent a bearing from seizing when a pump is started and stopped, by providing a hollow part having holes, in the shaft of the pump facing the bearing and by causing a fluid stored in the hollow part to flow out of the holes to the bearing when the pump is started and stopped. CONSTITUTION:A pump shaft 4 has a hollow part 11 facing a bearing 5b, 5c. Water W for lubricating the bearing 5b, 5c is stored in the hollow part 11. Holes 13, which communicate with the hollow part 11, are provided in the part of the pump shaft 4 facing the surface 12 of the bearing 5b, 5c. Small holes 14, which communicate with the hollow part 11, are provided in the other part of the pump shaft 4 above the bearing 5b, 5c. The lubricating water W is stored in the hollow part 11 to lubricate the bearing 5b, 5c at the first starting. The small holes 13 and a hole 12 are inclined to the radial direction to let the lubricating water easily flow when the pump shaft 4 is rotated in the direction of an arrow A.
