式軸受パッドまたは二層式軸受パッド３が配置される。A conventional guide bearing device for a hydraulic power generator is shown in FIGS. 1 to 3. A cylindrical skirt-like runner 2 is provided on the rotating shaft 1 side and is integrated with this shaft. At the bottom of this runner 2, there are multiple self-pump holes 2 across the runner 2.
Set up 2. In order to support this runner 2 along with a predetermined axis, a plurality of bearing pads 3 are used around the runner 2 to support the rotating runner 2 via an oil film. A one-piece bearing pad or a two-layer bearing pad 3 is then arranged.

ケース８を半径方向に貫通する。A backing plate 5 made of super steel alloy is enclosed and fixed on the back side of the second layer base metal 20 of the two-layer bearing pad 3. The contact point between the back surface of the back plate 5 and the pivot bolt 6 is supported on a spherical surface and is swingable. Pivot bolts 6 are arranged in a number corresponding to the plurality of two-layer bearing pads 3. This pivot bolt 6Vi passes through the bearing case 8 in the radial direction.

ダム１１が固定されている。Further, since a precise thread is machined between the bearing case 8 and the pivot bolt 6, a minute bearing clearance can be obtained by rotating the pivot bolt 6. For this reason, the pivot bolt 6 is fixed with the nut 7 after setting the optimum bearing clearance. The bearing case 8 is still fixed to the inner circumference of the bearing frame 14, and the bearing support plate 9 is fixed to the bottom of the bearing case 28, so that the two-layer bearing pad 3 is fixed.

欠点がある。The oil film is sheared between the runner 2 rotating at high speed and the 21-type bearing pad 3, and the resulting heat is removed to the outside using water flowing inside the oil cooler 12 as a medium. , the outer peripheral surface of the bearing frame 14 and the foundation are fixed. Therefore, the load from the shaft is transmitted to the signboard through the oil film, the two-layer pad bearing nozzle 3, the pivot bolt 6, the bearing case 8, the bearing frame 14, the base, etc. Note that the lubricating oil inside the bearing device has an oil level up to the top of the bearing pad 3. The pea-shaped guide bearing oil tank device of this hydroelectric generator has the following drawbacks.

ら下面へと矢印の方向に流れてしまって空っぽになる。That is, as the rotating shaft rotates, lubricating oil is ejected from the self-pump hole 22. In this direction, a strong flow occurs from the center (inner diameter) of the oil tank to the outside (outer diameter). Therefore, compared to S'fi 28 of the lubricating oil when it is stationary, during 20 revolutions of the runner, it becomes as shown by the broken line 29 in Fig. 3, and the oil level is lower as it is closer to runner 2, and as it moves further away from the runner. Experiments have shown that the higher the price, the higher the price. For this reason, lubricating oil tends to easily contain air bubbles. , Also, as shown in Figure 3,
As the oil flow of lubricating oil naturally flows in the downward direction where the flow is strong, as shown by the arrow, there are spaces between bearing pads where there is no sfw oil. damage will occur. Next, the two-layer bearing pad is provided with an oil passage groove to promote cooling of the bearing, and the self-pump hole 22. As shown in Figure 3, the jet of lubricating oil is so strong that, due to the siphon principle, the lubricating oil flows from the top surface to the bottom surface in the direction of the arrow, and becomes empty.

通油溝が通気孔となって、かえって軸受パッドの温度は
上昇し、軸受性能を低下させる原因となる欠点がある。Therefore, there is a drawback that air is naturally sucked from the oil passage groove. Therefore, the proportion of air mixed into the lubricating oil in the oil tank becomes extremely high, resulting in poor cooling efficiency. Also,
This has the disadvantage that the oil passage grooves become ventilation holes, which causes the temperature of the bearing pad to rise, causing deterioration in bearing performance.

支え板２３の上部に二層式軸受パッド３が乗っている。The purpose of the present invention is to provide an oil gutter to pick up the lubricating oil jet from the rotating cell pot hole, and introduce the jet into the groove of the bearing pad, thereby using the oil as a heat medium to heat the bearing pad. It is to cool down. The present invention will be explained with reference to FIGS. 4 to 7. 4 and 5 show a bearing support plate 23 and a gutter box 24 combined. A two-layer bearing pad 3 is placed on top of this bearing support plate 23.

８を流通する。In the two-layer bearing pad 3, the hole passing through the oil passage groove 18 and the communication hole 25 of the bearing support plate 9 coincide with each other, so that oil can flow therethrough. When the runner 2 rotates, lubricating oil spouted from the self-pump hole 22 is picked up by the oil sump box 24 and pressurized. This oil flows between the communication hole 25 and the oil passage groove 1 of the bearing pad 3.
8 is distributed.

お、図中４，１０は油流孔である。Next, other embodiments of the present invention are shown in FIGS. 6 and 7. This embodiment is a combination of a bearing support plate 23 and a sump box 24, and a bearing pad 27 made of a Bapit alloy and an iron back metal. The bearing pad 27 is provided with an oil passage hole 27 that penetrates in the height direction of the backing plate.A communication hole 25 is provided in the bearing support plate 9 to prevent the bearing pad from falling, and this and the bearing, C
It communicates with the oil passage hole of the rad 26 so that lubricating oil can always flow therethrough. Furthermore, an oil drain box 24 is provided on the lower surface of the bearing support plate 23. When the runner 2 rotates, lubricating oil jetted out from the self-pump hole 22 is picked up by the oil sump box 24 and pressurized. This oil flows through the communication hole 25 and the oil passage hole 27 of the bearing pad 26. At this time, the heat generated in the bearing pad 26 is carried outside using the oil flowing through the oil passage hole 27 as a medium. For this reason, bearing pad 2
6 can be cooled continuously while the rotation axis 1 is rotating. In addition, 4 and 10 in the figure are oil flow holes.

の経路が長くなるため冷却しやすい。According to the present invention, the bearing temperature of the bearing pad can be easily lowered while the runner is rotating. Furthermore, in order to pick up the jet by draining the oil, as shown in FIG. 8, the oil level indicated by the broken line does not rise outwards as in the conventional case, but instead becomes a fairly flat oil level. Additionally, as shown by the arrow, the lubricating oil circulation path becomes longer, making it easier to cool the lubricating oil.
