Check the imported bearing faults in the operation and processing method - bearing knowledge

In the process of using imported bearings, we may encounter some problems, especially in the treatment of the imported bearings of rolling noise, vibration, lubrication and temperature of the state, should be how to find and solve these problems, small make up today to share with you a piece of experience. We first from the vibration of the imported bearing, rolling temperature and the three aspects to talk about, because the bearing lubrication role is bigger, so as a separate chapter we exhibition from description: first is to check the import bearing vibration in the working situation from peeling, indentation, rust, crack and wear will be reflected in the imported bearing vibration measuring, imported bearing vibration damage of bearing is very sensitive, so, through the use of special imported bearing vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Due to the measured values of bearing or sensor installation position and different using conditions, thus requiring prior to each machine is analyzed by the measured value of the determined after judgment standard. Followed by the sound check import bearings rolling condition for damage, such as import bearings even with slight detachment also emits an exception and irregular, and with the sound of the measuring device can distinguish, therefore, the measuring apparatus, the size and quality of imported bearings rolling sound in operation to check, have the effect of prevention in advance. Finally is to check the temperature at which the imported bearing rotation if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. In general, imported bearing temperature, average on imported bearings of the outdoor temperature can conjecture. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Usually, the temperature of the imported bearing with operation began to slowly rise, 1 - After 2 hours to reach steady state. Imported bearings of normal temperature due to the heat capacity of the machine, heat dissipating capacity, rotational speed and load. When necessary, the use of thermal device can monitor the working temperature of bearing, and implement e. automatic alarm when the temperature is more than the household or stop to prevent the shaft accidents. About import bearing encountered in the operation temperature, noise and vibration situation at this point first, hope to have a little help to friends. 【 The bearing network]
