Bearing lubricating structure for rotary machinery |
摘要 |
A bearing lubricating structure for rotary machinery having a rotor rotatably supported by a bearing in a casing, an oil reservoir provided in a lower part of a bearing chamber accommodating the bearing, and an oil disk attached to an end of a rotating shaft of the rotor and immersed in lubricating oil in the oil reservoir so as to supply the bearing with lubricating oil splashed by the oil disk, wherein a guide groove is provided to collect lubricating oil flowing down an inner wall of a cover attached to an end of the casing; a suction nozzle is inserted into the guide groove to suck lubricating oil collected in the guide groove; a lubricant passage extends through the inside of the rotating shaft to supply the bearing with lubricating oil sucked through the suction nozzle; and an oiling nozzle is communicated with the lubricant passage and performs a pumping action induced by the rotation of the shaft, whereby a sufficiently large amount of lubricating oil is supplied to the bearing.
