This report describes the effectiveness of the application of acoustic diagnosis using vibration data for nspecting rotating machines. We usually apply the vibration diagnosis for the inspection of rotating machines on CBM(Condition Based Maintenance). However, with the vibration diagnosis, sometimes we annot discover the cause of abnormal sounds fro m rotating machines. Therefore, we tried another iagnosis. We converted the vibration data to the acoustic data and then inspected the abnormal sounds. We se...

This paper describes effectiveness of applying acoustic diagnosis to the greasing work. When we hear abnormal sounds from grease lubricated bearings, we try greasing. As a result, usually abnorm al sounds fade away. But after a while sometimes the sounds appear again. Therefore we try greasing again. The sounds fade away at the time but later appear again. We try greasing again and agai n but the results are the same. By this time, the temperature of the bearing has increased a lot. If the temperature incr...

This paper describes study of effectiveness of applying acoustic diagnosis to CBM(Condition Based Maintenance). We usually measure data of vibration of rotating machines with accelerometer to monitor the condition of it. This work is dangerous because we put the accelerometer near the rotating shaft of the machines by hand. Therefore we tried the non-contact sensing using a microphone of acoustic diagnosis and checked the data. As a result, we got the enou gh data for the monitoring safely.When rotating ma...
