In the general case, FAG bearings excitation does not occur, but if excitation occurs, then will need to properly check the situation. Bearings used in the process some of the causes and emergency measures:
A bearing sound move
Using audio equipment size and sound quality sound check the operation of the bearing, FAG bearings even slightly peeling and other damage, abnormal tone and irregular sound measuring device will be distinguished sound measurements.
2 bearing vibration
Bearing vibration of the bearing damage is very sensitive, such as peeling, indentation, corrosion, cracks, wear in the bearing vibration measurement reflected, therefore, by using a special bearing vibration measurement (frequency analyzer, etc.), measuring the magnitude of the vibration, the frequency analysis, can be inferred through unusual circumstances. Premise for the bearing mounting location of the sensor used or the measurement values are different, so each machine will need to determine in advance the scale of analysis and comparison of measured values.
3, the bearing temperature
Bearing temperature, generally bearing outside the room temperature can be inferred that if the holes can be used to directly measure the temperature of the bearing outer ring, is more appropriate. Under normal circumstances, the bearing operating temperature for 1-2 hours, and slowly reached into chaos state. The heat capacity of the machine bearing the normal temperature, heat capacity, speed and load changes. If the inspection and troubleshooting lubrication FAG bearings manipulation, install the appropriate department, bearing temperature will Passed, an exception will be thrown at high temperatures stop running, take the necessary preventive measures.
FAG bearing damage inspection after the demolition, according to a damaged bearing, bearing failure and damage to determine the cause.
Crisp sound, sharp squeak noise may be caused by improper bearing clearance because of insufficient lubrication can also cause metal sound. Dent on the bearing outer track will cause vibration. As if the injuries caused by the percussion equipment generates noise, which different speed levels. If there is intermittent noise, and then move the department, may be damaged, the sound thrown up, when the surface is damaged Release Date, if the hissing "sound pollution often caused severe damage FAG bearings, and cause irregular huge noise.
But usually replaced once at this time is not necessary FAG Bearings. Therefore, damage, of course, can also be perceived by listening. Such as using better methods, such as electronic health monitoring equipment, prior to the eruption of the operation.
