    • PROBLEM TO BE SOLVED: To provide a rotating machine capable of suppressing the grease filled in a bearing from being washed away.SOLUTION: A drain hole 4e communicated with a space 8 configured between the bearing 6 and a seal member 7 with respect to a case 4 is formed. Accordingly, even when liquid in a liquid storage chamber 4a leaks into the space 8 beyond the seal member 7, the liquid can be discharged from the drain hole 4e. Further, an atmosphere introducing hole 4f which is communicated with the space 8 is disposed. Thereby, the inside of the space 8 can be kept at an atmospheric pressure and, even when the drain hole 4e is blocked with liquid, the liquid can be reliably discharged through the drain hole 4e. Therefore, even when the liquid leaks beyond the seal member 7 to the bearing 6 side while it is suppressed that the liquid in the liquid storage chamber 4a leaks from a gap between the case 4 and a rotating shaft 3 by the seal member 7, it can be suppressed that the grease filled in the bearing 6 is washed away.
    • 要解决的问题:提供一种能够抑制填充在轴承中的润滑脂被冲洗掉的旋转机械。 解决方案:形成与相对于壳体4在轴承6和密封构件7之间构造的空间8连通的排水孔4e。 因此,即使液体储存室4a中的液体泄漏到超过密封构件7的空间8中,液体也可以从排水孔4e排出。 此外,设置与空间8连通的气氛导入孔4f。 因此,空间8的内部能够保持在大气压下,即使当排水孔4e被液体堵塞时,也可以通过排水孔4e可靠地排出液体。 因此,即使当液体储存室4a中的液体被密封构件7从壳体4和旋转轴3之间的间隙泄漏的情况下,即使液体在密封构件7之外泄漏到轴承6侧, 可以抑制填充在轴承6中的润滑脂被冲走。 版权所有(C)2013,JPO&INPIT
