In the system operation, the vibration of the spherical rod end bearing is very sensitive to the damage of the bearing, such as peeling, indentation, rust, crack, wear, etc. These phenomena will be reflected in the vibration measurement of the rod end joint bearing. Therefore, the magnitude of the vibration can be measured by using a special rod end joint bearing vibration measuring device (frequency analyzer, etc.), and the specific situation of the abnormality cannot be inferred by the frequency division.
For the vibration condition of the spherical rod end bearing, the measured value often differs depending on the specific flying working condition or the sensor installation position. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard. During the operation of the bearing, there must be phenomena such as sound, temperature and vibration.
For the spherical rod end bearing in operation, good maintenance is required. Generally, the abnormal change of the bearing can be found by listening, touching, observing and using the bearing fault diagnosis instrument. The rod end joint bearing can be judged according to the changing state. Working status.
