ABSTRACT:
This invention is related to an apparatus for detecting an abnormal condition and limit of use of a forced lubricating plain bearing which supports a rotary shaft. An oiling pressure bore is formed in the plain bearing, and a pressure detector is connected to this oiling pressure bore. The oiling pressure bore is communicated with a lubricating oil feed bore via a throttle element. A closed portion of the oiling pressure bore is melted and broken by the heat generated when seizure occurs on the plain bearing, to cause a decrease in the oil pressure. This decrease in the oil pressure is detected to ascertain that the plain bearing is in an abnormal condition or reaches a limit of use.
