Document Type and Number:
Japanese Patent JP2020084803
Kind Code:
A
Abstract:
To provide a submerged pump motor and a shaft support device for a pump rotating shaft.SOLUTION: A shaft support device 3 is fixed to a casing 21 of a motor 1 or a pump 2 and is provided so as to be rotated while supporting the motor 1 or a rotating shaft 22 of the pump 2. The shaft support device 3 is provided with a bearing table 31 which is fixed to the casing 21 and is equipped with a ball bearing 32 and a thrust bearing 33. An inner hole of the bearing is provided with a bush 34 for the rotating shaft 22 to enter into, an adjustment screw bush 35 fastened with an end of the rotating shaft 22 and an end surface of the bush 34 is screwed, and the rotating shaft 22 is thereby provided so as to rotate on the bearing, a vertical position of the rotating shaft 22 is adjustable, and the ball bearing 32 and the thrust bearing 33 are provided so that they receive heavy load from components such as the rotating shaft 22 and prolong service life of the submerged pump 2.SELECTED DRAWING: Figure 2
