Abstract

PURPOSE: To make it possible to monitor the malfunction of a bearing at all times by detecting the operating vibrations of the bearing and the discharging condition of lubricating oil.
CONSTITUTION: Control valves 4 and 5 are connected with preset positions of the lubricating oil charging and discharging pipes 2 and 3 which have communications with the upper and lower sides of a bearing 1 or a test piece assembled in a machine such as a rotor. a foreign substance detector 7 is connected with the discharging pipe 3, and a vibration gauge 6 is attached to the bearing outer race 1a and connected with an arithmetic control unit 8. Thus, when any abnormal phenomena take place in the bearing 1, the vibratory output waveforms including the shock waveforms varying periodically or non-periodically are detected by the vibration gauge 6. When the waveforms become larger than the discrimination level, the control valves 4 and 5 are opened to effect the charge of the oil in a preset quantity. When the oil is discharged, a foreign substance is, if any in the oil, detected by the detector 7. Then, the valves 4 and 5 are opened so that the foreign substance is discharged from the bearing 1 together with the lubricating oil.
