Claims

[Claims for Utility Model Registration] ■ A rotating shaft of a vertically installed vertical rotating machine, a lower bearing that rotatably supports the lower part of the rotating shaft and receives upward thrust from the rotating shaft, and the rotating shaft. A bearing device for a vertical rotating machine, comprising an upper bearing that rotatably supports an upper part of a shaft and receives downward thrust of the rotating shaft. 2. The lower bearing was housed in a lower bracket that covered the lower end surface of the cylindrical frame into which the rotating shaft was inserted, and was configured to be prevented from moving upward by a lower bearing cover that covered the lower bearing: Gray:::::Blue request range 1
The inner ring of the vertical rotation 3 lower bearing described in Section 3 is mounted on the rotating shaft, and is clamped and fixed between a grease extermination ring mounted on the rotating shaft and a step surface of the rotating shaft in the lower bracket, The outer ring of the lower bearing is attached to the lower bracket, the upper end surface thereof is prevented from moving upward by a lower bearing cover, and the lower end surface is covered with the lower bracket through a gap. A bearing device for a vertical rotating machine according to claim 2 of the patent registration claim.
