We first talk about the three aspects of the vibration, rolling and temperature of the imported bearings. Since the lubrication in the bearing is relatively large, we will expand it as a separate chapter to explain:
The first is to check the vibration of the imported bearings during operation.
From the peeling, indentation, rust, crack, wear and so on, it will be reflected in the vibration measurement of the imported bearing. The vibration of the imported bearing is very sensitive to the damage of the bearing. Therefore, by using a special imported bearing vibration measuring device (frequency analysis) The magnitude of the vibration can be measured, and the specific situation of the abnormality cannot be inferred by the frequency division. Since the measured values differ depending on the conditions of use of the bearing or the mounting position of the sensor, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
The second is to check the sound of the imported bearings when rolling
Because the imported bearings emit abnormal sounds and irregular sounds even if they are slightly peeled off, the sounder can be used to distinguish them. The sounder is used to check the size and sound quality of the running bearings. , play a role in prevention in advance.
Finally, check the temperature at which the imported bearing rotates.
If the oil hole can be used to directly measure the bearing outer ring temperature, it is more suitable. Under normal circumstances, the temperature of the imported bearings can generally be inferred based on the temperature outside the imported bearings. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply and abnormal temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions. Usually, the temperature of the imported bearing rises slowly as the operation starts, and reaches a steady state after 1-2 hours. The normal temperature of the imported bearings varies with the heat capacity, heat dissipation, speed and load of the machine. If necessary, use the thermal sensor to monitor the working temperature of the bearing at any time, and automatically alarm the household when the temperature exceeds the specified value or stop the burning shaft accident.
Regarding the temperature, sound and vibration encountered in the operation of imported bearings, I would like to talk about it here. I hope I can help my friends.
