It is important to increase productivity and economy that faults can be identified or predicted for running bearings without removal checks.
The main identification is as follows:
1) Recognition by sound
Recognition through sound requires a wealth of experience. The sound of the bearing and the non-bearing sound must be fully trained to recognize the bearing. To this end, as far as possible by professionals to carry out this work. The sound of the bearings can be clearly heard by attaching the sound rod to the housing.
2) Identification by operating temperature
This method is a comparative method and is limited to situations where the operating state is not changed. Therefore, continuous recording of the temperature must be carried out. In the event of a failure, the temperature not only increases, but also changes irregularly. This method is suitable for sound recognition.
3) Identification of lubricants
The analysis of lubricant sampling is judged by the degree of contamination, whether it is mixed with foreign material or metal powder, etc. This method is particularly effective for bearings or large bearings that cannot be viewed close to observation.
Bearings cannot be directly observed during operation, but bearing abnormalities can be detected through the condition of noise, vibration, temperature, lubricants, etc.
