Abstract

PURPOSE:To make it possible to early detect the abnormal conditions of a bearing, such as inclination, by a method wherein the metal temperature in the neighborhood of the bearing sliding surface is detected at a plurality of portions, and the metal temperature difference between these portion and the reference temperature difference value are compared with each other. CONSTITUTION:In the detecting position 10 on the Babbit metal 5 surface of the lower-half bearing 2, four holes 10a are formed, two of them being located at axially symmetric positions and the other two at circumferentially symmetric positions, and metal temperature sensors 12 are installed in the holes 10a. The metal temperature signals T1-T4 from the metal temperature sensor 12 at the four portions are inputted to an arithmetic apparatus 18, to which the bearing oil temperature signal 0 is also inputted from an oil temperature sensor 7c. On the other hand, the load, the number of revolutions R and the on/off signal of the oil lifter are inputted to the arithmetic apparatus 18 from an operational condition detector 17. In said arithmetic apparatus 18, the metal temperature difference between said portions and the reference temperature difference value are compared with each other in order to diagnose the existence to abnormality of the bearing. Thereby, the abnormal conditions of the bearing can be detected at an early stage.
