Abstract

PURPOSE:To reduce the cost of an oil feeder by disposing a rotary shaft and a driving shaft in such a manner as to interlock with each other through a clutch, and providing a fixed-quantity pump as a supply pump. CONSTITUTION:An oil feeder comprises fixed-quantity pumps 26 and discharge pumps which are mounted on a driving shaft 15, and a pulley 28a mounted thereon through a clutch 27. At the start of operating, the fixed-quantity pumps 26 are driven to supply oil to a bearing 21. When driving devices 14, 17 are stopped due to power failure, the clutch 27 is operated to rotate the driving shaft 15 with turning force of a rotary shaft 20, so that lubricating oil is discharged from the bearing. This arrangement can eliminate the need of an upper tank, reduce the cost of the appararus and reduce the apparatus to a compact size.

続行される。When starting the operation of the centrifugal extractor 19, first, the clutch 27
At the same time, the drive device 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. After that, bearing 2
1 is sufficiently lubricated with oil, the drive device 17 is turned on, and the centrifugal shaft extractor 19 is smoothly started to operate. 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. In addition, due to a power outage, the drive unit 14
．． 17 has stopped, the clutch 27 is activated, and the rotational force of the rotating shaft 200, which continues to rotate due to inertia even when the drive device 7 has stopped, is transferred to the drive shaft 5 via the pulley 28b, belt 29, and pulley 28a. The signal is transmitted and the drive shaft 15 is rotated. As a result, the metering pump 26 and the discharge pump 24
The bearing 21 is driven until the rotating shaft 20 stops rotating.
The supply of lubricating oil to and the discharge of lubricating oil from the bearing 21 continue.
