PURPOSE:To transfer oil feed lines in accordance with the quantity of abrasion particles by providing an oil feed line of lubricating oil with filters and an oil feed line with no filter in parallel and providing a detector of the abrasion particles on a return line of lubricating oil. CONSTITUTION:Lubricating oil in a lubricating oil tank 30 is absorbed by a pump 31 and fed to the oil feed hole 9 of a bearing through an oil temperature control unit 17. The lubricating oil discharged through the return oil hole of the bearing is returned to the lubricating oil tank 30 through a return line 32. An oil path transfer valve 11 and three passages, i.e., oil filter passages 12a, 12b and a direct pipe path 12c are provided between the oil temperature control unit 17 and oil feed hole 9, and a sample oil extraction pipe 18, an abration particle detector 14, and a return pipe 19 are provided in the middle of the return line 32. The lubricating oil temperature is controlled or the transfer valve 11 is switched to allow the lubricating oil to flow through the filter passages 12a, 12b in accordance with the abrasion particle quantity in the lubricating oil. |
