く損なわれるという問題があった。In the tilting pad bearing, the cold and fresh oil is directly supplied to the surface of the rotary shaft 1, but the nozzles 5a and 5b are arranged at right angles to the surface of the rotary shaft 1. Therefore, most of the oil released toward the rotary shaft 1 is repelled by the rotation of the rotary shaft 1,
Only the oil that slightly adheres to the surface of the rotary shaft 1 is carried into the clearance between the bearing pads 2a to 2d and the surface of the rotary shaft 1 by the rotation of the rotary shaft 1, and the bearing lubricates. However, in addition to the small supply amount, the bearing clearance is very small when the rotating shaft is a thin shaft and the bearing is a small high-speed rotating body, so the amount of oil to the clearance is sufficient and stable over time. Will not be supplied. Therefore, there has been a problem that the temperature rise of the bearing and the temporal change of the temperature become large, and the function as the bearing is greatly impaired.

It is intended to provide a pad bearing.

る。According to the present invention, since the lubricating oil jetting portion from the oil supply nozzle is arranged tangentially to the rotary shaft, the oil jetting from the nozzle easily enters the clearance opening portion of the bearing. Further, since it is directed straight toward the clearance opening between the front edge of the bearing pad and the surface of the rotating shaft, the oil ejected from the nozzle easily directly enters the clearance opening of the bearing, Lubricating oil is sufficiently supplied to the clearance opening of the bearing, and insufficient lubrication of the bearing can be prevented. Furthermore, by forming a canopy so that the front edge of the pad covers the tip of the nozzle, or by providing a reflective shade at the tip of the oil supply nozzle, the oil that has come out of the nozzle hits the surface of the rotating shaft and the side wall of the pad and bounces off. On the other hand, since the eaves or the reflective shade returns to the direction of the clearance opening of the bearing, the supply of lubricating oil to the clearance opening of the bearing is further increased, and the lubrication function of the bearing can be further enhanced.
