Abstract

PURPOSE: To easily detect an abnormal bearing, by installing the metal temperature sensor to the part which is right under the lower half bearing so as to be symmetrical to the axial direction, also providing the metal temperature sensor at intervals of some distance in the circumferential direction in the same way, and monitoring the temperature.
CONSTITUTION: The metal temperature signals T1WT4 from the metal temperature sensor 12 embeded in the 4 detection holes 10 which are right under the lower half bearing 2 are input to the diagnostic arithmetic device 100. On the other hand, not only the operation conditions 17 such as load, rotational frequency, turning on-off, etc. but also the oiling temperature signal T0 from the bearing oiling temperature sensor 12a are input to the diagnostic arithmetic device 100. And the sound signal energy value γ from he sound sensor 16 and the sound signal generation frequency value γn measured by the counter 21 are also input to the diagnostic arithmetic device 100, and the existence of abnormality is diagnosed by the bearing metal wiper, etc. from these signals in the device 100.
