場合ほどこの傾向は顕著になる。Incidentally, FIG. 7 (a)
As shown in FIG. 5, the flow of the lubricating oil in the clearance between the thrust disc surface and the bearing pad indicated by the arrow A 1 is dragged by the thrust disc surface rotating in the N direction. Due to the inclination of the bearing pad, the clearance is large at the leading edge of the pad and small at the trailing edge, so that not all of the lubricating oil that has flowed in from the leading edge reaches the trailing edge as shown by arrow B. The light is deflected in a direction perpendicular to the rotation direction and flows out from the inner and outer peripheral edges as shown by arrow C. During this time, the lubricating oil pressure rises in the direction of movement and the temperature rises due to frictional heat, so the lubricating oil passing through the small clearance at the trailing edge shown by arrow A 2 is in a high temperature state. As shown in Fig. 7 (a), this high-temperature oil further flows into the bearing pad on the downstream side as it is due to the drag of the thrust disk, so the temperature of the lubricating oil tends to gradually rise, and the load capacity decreases. Then, the reduction of the oil film thickness causes the surfaces to come into contact with each other, causing problems such as abnormal wear, seizure, and carbonization of lubricating oil. In particular, this tendency becomes more remarkable when used under the condition that the rotation speed is high.

性が大きくなっている。That is, in this bearing, even if it is unavoidable that high temperature oil is dragged by the thrust disk surface and re-enters the bearing pad, the remaining lubricating oil that can flow in through the large clearance at the leading edge is Cold oil is introduced directly from the lubricating oil supply source through the leading edge oil distribution groove 25, thereby reducing the average temperature of the bearing pad surface. However, the effect is limited because it does not remove the hot oil layer itself that is dragged by the thrust disk to move. As the motion conditions required for the bearing become higher in speed and higher in surface pressure, heat generation on the bearing pad surface increases, and the possibility of wear and seizure damage on the bearing pad surface increases.

油分布溝を設けた。In the tilting pad thrust bearing of the present invention, the back surface of a plurality of fan-shaped bearing pads arranged concentrically around a rotating shaft is supported by a point so that the bearing pad can be tilted. By doing so, the force or load in the axial direction of the rotating shaft is generated by the plurality of bearing pads via the lubricating oil between the member on the rotating shaft side that rotates along the front surface of the bearing pad and the front surface of the bearing pad. In the supporting tilting pad thrust bearing, an oil distribution groove communicating with a lubricating oil supply source is provided on the front surface of each of the bearing pads near the rear edge in the rotation direction of the rotary shaft.

The vicinity of the trailing edge in the rotational direction of the bearing pad is a place where the lubricating oil having the smallest clearance with the member on the rotating shaft side and the highest temperature in the bearing pad passes. As described above, since the lubricating oil having a low temperature flows out here, a layer of the lubricating oil heated to a high temperature in the bearing pad is subjected to the action of the low-temperature lubricating oil flow at the place where it is about to flow out from the bearing pad. As it is disturbed, most of it flows out from the inner and outer peripheral edges of the bearing pad, and the low-temperature lubricating oil re-enters the next bearing pad.

In the vicinity of the trailing edge near the downstream edge in the rotational direction N of 0, an oil distribution groove 5 extending in the radial direction to substantially the entire width of the thrust bearing is provided. The oil distribution groove 5 is connected to the oil supply passage 6 by a plurality of oil holes 7. This oil supply passage 6 is opened on the outer peripheral side surface of the bearing pad and is connected to an oil supply pipe 9 by a joint 8 so that lubricating oil can be supplied from an oil supply source not shown in the figure.

Of the low temperature lubricating oil ejected at the location where the layer of the lubricating oil heated by the bearing pad indicated by arrow AA 1 in FIG. While being disturbed by the action of the flow, most of it is discharged from the inner and outer peripheral edges of the bearing pad as indicated by an arrow CC. Therefore, the lubricating oil whose temperature has been lowered flows out from the bearing pad and flows into the bearing pad on the downstream side as shown by an arrow AA 2 .
Note that BB in FIG. 7B shows the flow of the surrounding lubricating oil flowing into the clearance between the bearing pad and the thrust disk 10 at the front edge of the bearing pad.

スラスト軸受とすることができる。According to the present invention, an oil distribution groove is provided on the front surface of the bearing pad in the vicinity of the trailing edge in the rotational direction of the rotary shaft, and the lubricating oil having a low temperature is jetted to pass through the bearing pad surface to raise the temperature. Lubricating oil can be effectively removed from the gap between the rotating member and the bearing pad and cooled. As a result,
Of the lubricating oil flowing into the next bearing pad, the amount of recirculation of the oil flowing out from the previous bearing pad, which is the cause of the high temperature oil, can be reduced and the temperature can be lowered. As a result, the viscosity of the lubricating oil can be increased, the load capacity of the bearing can be increased, and the film thickness of the lubricating oil can be increased, resulting in contact between the rotating side member and the bearing pad, resulting wear, and abnormal heat generation. It is possible to obtain a tilting pad thrust bearing which can avoid such problems as described above, has a high load capacity, and is less likely to cause bearing damage such as seizure or wear.
