The spacing between the flow passages formed by the protruding tip and the rotating shaft 1 is narrower than the spacing between the flow passages directly below the roller bearing 2, and a sorting centrifugal centrifuge that rotates together with the rotating shaft 1 is placed between the rollers and the bearing 2. A drum 10 is provided. This sorting centrifugal drum 1
0, there is a passage hole 10a through which lubricating oil passes in the direction (axial direction) in which the rollers pass toward bearing 2, and a foreign object whose mass is heavier than the lubricating oil is located perpendicular to the passage hole 10a in the radial direction. Centrifugal force is applied to dirt and debris while they pass through the passage holes 10a of the rotating sorting centrifugal drum 10 together with lubricating oil, and discharge holes 10b are provided radially for separating and discharging the lubricating oil to the outside. Furthermore, in this embodiment, a pocket 6 is provided in the bearing housing 3 near the sorting centrifugal drum 1o by forming a wall space extending in the radial direction.

が到達する。According to the configuration of this embodiment, lubricating oil for the purpose of cooling and lubricating the roller bearing 2 is introduced into the roller bearing 2 from the oil chamber 4 through the flow path 5, The rollers lubricate the shear bearing 2 and flow upward in the direction of the arrow, but the lubricating oil passes through the passage hole 1oa of the sorting centrifugal drum 10 before the rollers reach the shear bearing. Here, the lubricating oil that has entered the passage hole 1oa rotates together with the sorting centrifugal drum 10 and is given centrifugal force. Therefore, foreign matter and dirt that are relatively heavier than the lubricating oil mixed in the lubricating oil are discharged from the discharge hole 10b due to centrifugal force and deposited in the pocket 6. Therefore,
Lubricating oil that is free from foreign matter and dirt reaches the roller bearing 2.

命を大幅に延ばすことが可能となる。Therefore, with the configuration of this embodiment, even if foreign matter or dust is mixed in the lubricating oil, this foreign matter or dust will hardly be mixed into the raceway surface of the roller bearing 2, so the balls 2A
, or the inner ring 2B and outer ring 2C are not damaged,
There is no fear that the rollers will damage the bearing 2, and the life of the bearing can be significantly extended.

採用する場合には非常に有効である。According to the bearing support device for a vertical rotating electrical machine of the present invention as described above, the rotating shaft is formed in a part of the flow passage formed below the bearing that supports the rotating shaft disposed vertically and through which lubricating oil flows to the bearing. Since it is equipped with a device that rotates with the lubricating oil and applies centrifugal force to the lubricating oil flowing through it, even if the lubricating oil contains foreign matter or dust, the foreign matter or dust can be removed by the device.
Foreign objects, dust, etc. will not reach the bearings, so
Since the bearing will not be damaged, it is very effective when used in this type of bearing support device.
