Three identification methods of bearing faults

Bearing, as a precision part of mechanical equipment, how to improve the productivity of the factory, first of all, the performance of mechanical equipment must be good, and the bearing is closely related to the performance of mechanical equipment. Therefore, the factory shall conduct necessary inspection on the bearings in mechanical equipment during production and processing. Here are three identification methods of bearing faults, which I hope will be helpful to you.
1. Recognition by sound
Recognition by sound requires a wealth of experience. Must be adequately trained to recognize bearing and non bearing sounds. Therefore, special personnel should be assigned to carry out this work as far as possible. The sound of the bearing can be clearly heard by sticking the listener or listening stick to the shell.
2. Identification by operating temperature
This method belongs to the comparative identification method, which is limited to the situation where the running state does not change much. For this purpose, continuous temperature recording must be carried out. In case of failure, the temperature will not only rise, but also change irregularly. This method should be used together with voice recognition method.
3. Identification by lubricant status
The lubricant shall be sampled and analyzed to judge whether it is polluted or mixed with foreign matters or metal powder. This method is especially effective for bearings that cannot be close to observation or large bearings.
