良い。 When starting the operation of the centrifugal extractor 19, first, the drive device (electric motor) 14 is turned on to drive the metering pump 26. As a result, the lubricating oil cooled by the cooler 10 is supplied from the tank 11' to the bearing 21 via the flow meter 23 and the conduit 33. At this point, the centrifugal extractor 19 is stopped. Thereafter, with the bearing 21 sufficiently filled with lubricating oil, the drive device (electric motor) 17 is turned on, and the centrifugal extractor 19 is thereby started to operate smoothly. The lubricating oil supplied to the bearing 21 is returned to the tank 11' via a sight glass 25 and a conduit 34 by a discharge pump 24 driven by a drive device 14 together with a metering pump 26. At this point, due to the operation of the centrifugal extractor 19,
Although the pulley 28a is rotating via the pulley 28b and the belt 29, the drive of the drive shaft 15 is not affected because the clutch 27 is disengaged.
That is, during normal operation, the clutch 27 separates the rotation system between the drive shaft 15 and the rotating shaft 20.
In addition, the drive device (electric motor) 14,
17 has stopped, the clutch 27 is actuated, and the rotational force of the rotating shaft 20, which continues to rotate due to inertia even when the drive device (electric motor) 17 has stopped, is driven through the pulley 28b, belt 29, and pulley 28a. The signal is transmitted to the shaft 15 to rotate the drive shaft 15. As a result, the metering pump 26 and the discharge pump 24
is driven, and the supply of lubricating oil to the bearing 21 and the discharge of lubricating oil from the bearing 21 continue until the rotation of the rotating shaft 20 stops. In addition, the clutch 27
The clutch may be of any type, electrical or mechanical, as long as it can be connected only during a power outage.

ンパクト化できる。(1) Even if the drive device stops during a power outage such as a power outage, the rotating shaft continues to rotate due to inertia, and the rotational force of the rotating shaft can drive the metering pump and discharge pump via the pulley and clutch, and the rotating shaft stops rotating. Since the supply of lubricating oil to the bearing and the discharge of lubricating oil from the bearing can be continued until the end of the bearing, seizing accidents of the bearing can be prevented. Furthermore, since the upper tank can be made unnecessary, the cost of the device can be reduced and the device can be made more compact.
(2) 定量ポンプにより潤滑油を軸受に供給してい

供給することができる。(3) When the drive unit stops due to a power outage, etc., the rotational force of the rotating shaft, which continues to rotate due to inertia, can drive the metering pump and discharge pump via the pulley, belt, and clutch. It is possible to supply the bearing with an amount of lubricating oil commensurate with the rotation.

They may be interlocked and interlocked by a chain via a clutch, or by gears. Further, although not shown, the present invention can also be applied to a rotating machine in which a rotating shaft and a driving shaft are directly connected by the clutch.

By connecting the rotary shaft and the rotary shaft so that the inertia of the rotary shaft installed on the bearing device becomes the driving source for the oil pump during a power outage, it is possible to prevent the occurrence of bearing seizing accidents. This has the effect of reducing equipment costs.
