ない不具合がある。[0004] The lubricating oil supplied into the oil receiving portion 14 of the disk 3 is carried upward by being dragged by the wall surface of the oil receiving portion 14 of the rotating disk 3. FIG. 4 shows the relationship between gravity, centrifugal force and drag force acting on the lubricating oil in the oil receiving portion 14 of the disk 3 at this time,
This schematically shows changes in the thickness of the lubricating oil layer and the like. The lubricating oil supplied at the lowermost position is carried by being dragged by the wall surface of the disk 3 in the rotation direction N. At the point A in the figure, the gravity GA is directed parallel to the wall surface, so that the drag force is canceled out, a part of the fall falls, and the amount of lubricating oil carried decreases. At point B, gravity G
Since B acts in the direction of separating the lubricating oil from the wall surface, the amount of the lubricating oil is further reduced. As a result, the thickness of the lubricating oil layer becomes substantially as shown by the broken line, becomes much smaller than the thickness of the lubricating oil supplied at the lowest point, and is scraped off by the scoop 11 near the top. Thus, in the conventional disk lubricated bearing, even if the amount of lubricating oil to be supplied is increased in consideration of the fact that the lubricating oil falls during the rotation and decreases, the component of gravity is higher at a position higher than the point A. Therefore, the amount of the lubricating oil falling tends to increase, and there is a limit in increasing the amount of the lubricating oil that is effectively used. Therefore, in the conventional disk lubricated bearing, since the required lubricating oil amount increases, the lubricating oil amount is relatively insufficient at high speed rotation, and the bearing metal 7 tends to suffer damage such as seizure, temperature rise, and wear. There is a problem that can be adopted only when the rotation speed is low.

受の適用範囲を広げることができる。In a conventional disk lubricated bearing, even if the amount of lubricating oil to be supplied is increased in consideration of the fact that the lubricating oil drops during the rotation and decreases, the component force of gravity increases at a high position. The amount of the lubricating oil falling also tends to increase, and there is a limit in increasing the amount of the lubricating oil that is effectively used. Therefore, conventional disk lubricated bearings require relatively little lubricating oil during high-speed rotation where the required amount of lubricating oil increases, and the bearing metal tends to suffer damage such as seizure, temperature rise, and wear. Although there is a problem that can be adopted only when the number is small, in the present disk lubrication type bearing, a large number of small chambers 19 divided in the circumferential direction by a partition plate are provided on the side wall surface of the oil receiving portion 14 in the disk 3. The opening in the oil receiving portion 14 and the rotation shaft 1 of the small chamber 19
When the inner peripheral wall 20 on the side closer to the small chamber 19 comes near the top, the lubricating oil is discharged from the small chamber 19 into the oil receiving portion 14 of the disk 3.
Is inclined toward the center of the disk 3 so as to flow down , and the small chamber 19 is inserted at the lowest position.
In order to be able to put lubricating oil and store it securely,
The opening side of the partition plate that divides the small chamber 19 in the circumferential direction is
The lubricating oil which is inclined in the rotational direction N of the disc 3 and which cannot be dropped and cannot be carried up during the rotation without these small chambers 19 is reliably stored and carried up to the bearing metal 7. The amount of lubricating oil to be supplied can be increased, and the amount of lubricating oil necessary for lubricating the bearing metal 7 at the time of high-speed rotation is secured. Can be avoided, and the application range of the present disk lubricated bearing can be extended to higher speed rotation.
