摘要： PURPOSE:To enable a guide bearing to be well cooled, by tilting an oil delivery hole with a position of its delivery side lower than that of its suction side and providing a step difference on the internal wall of a guide runner in an upper part of the suction side, in the case of a guide bearing device or the like of a vertical shaft water turbine generator. CONSTITUTION:An oil delivery hole 5a drilled in a guide runner 1a is tilted at an angle theta so that a delivery side M of the hole is positioned lower than its suction side N, and step difference 8 is provided on an internal wall of the guide runner in an upper part of the suction side N. In this way, oil in an annular oil chamber 3a is easily sucked into the oil delivery hole 5a, and its delivery oil flow (b) is directed toward the bottom part side of an oil tank 3 in almost the same direction as the direction of a circulative oil flow (a) in the bottom part of a guide bearing 2, never interfering with the circulative oil flow (a), thus the circulative oil flow (a) well circulates to perform good cooling of the guide bearing 2.
摘要翻译：目的：为了使引导轴承能够被良好的冷却，通过使排油孔的位置比其吸入侧的位置倾斜，并且在导向轴的上部的导向件的内壁上提供台阶差在垂直轴水轮发电机的导向轴承装置等的情况下的吸入侧。构成：在导向流道1a中钻出的输油孔5a以角度θ倾斜，使得孔的输出侧M位于比其吸入侧N低的位置，并且台阶差8设置在导向件的内壁上在吸入侧N的上部的流道。这样，环状油室3a中的油容易地被吸入到排油孔5a中，并且其输送油流（b）指向油的底部侧在与导向轴承2的底部的循环油流（a）的方向大致相同的方向上，不会与循环油流（a）干涉，所以循环油流（a）很好地循环到对导向轴承2进行良好的冷却。

摘要： PURPOSE:To prevent the oil from leaking to outside the electric machine by furnishing an air suction part between the exhaust pipe and oil collector device and by balancing the intrusion amount with the attraction amount. CONSTITUTION:An air suction part 18 to feed the air 19 into the exhaust pipe 11 is furnished between the exhaust pipe 11 and oil collector device 15. By such an arrangement the air 19 is fed in the exhaust pipe 11, and the intrusion amount including the oil mist 7 to be intruded in the suction part 13 can be set at an amount approximately the same as the attraction amount of the suction part 13, so that filtration at the filter part 12 will be done well. Accordingly, the air 19a exhausted to outside the electric machine is got rid of oil to ensure good prevention of oil leakage.

摘要： PURPOSE: To prevent the seizure of a thrust bearing device for a heavy water wheel generator or the like, by dividing a collar into an inner and an outer collars and making the outer collar of a monolithic body whose inside diameter is large than the outside diameter of a flange.
CONSTITUTION: The collar of a bearing device is divided into an outer collar 8 and an inner collar 9. The inner collar 9 is split into two sections. The outer collar 8 is made monolithic. Thrust bearings 6, 7 support the collar 8 slidably. The collar 9 is fitted on the central part of a shaft 1. The collar 8 whose inside diameter D
3 is larger than the outside diameter D
1 , D
1 ' of flanges of the shaft 1 is fitted on the peripheral surface of the collar 9. The thrust bearings 6, 7 support the collar 8 on both its sides so that the collar can slide. Since a sliding section has no divided parts, oil which makes films on the thrust bearings 6, 7 does not escape. Therefore, the thrust bearings 6, 7 are protected from seizure.
