Solution to the rolling bearing failure in the process of operation

Bearing will discuss with you how to check the rolling bearing in operation in the process of rolling noise, vibration, temperature and lubrication condition, in order to find and solve problems in time, avoid unnecessary economic losses. Today is mainly import inspection of rolling bearings rolling noise, vibration and temperature. First is based on the voice of the rolling bearing rolling to identify and check, we can use voice detector to check the size of the rolling bearing and sound quality. Because even a slight peeling and other damage, rolling bearing also can produce abnormal sound and irregular. Therefore, sound detector can be used to distinguish and play a role of early prevention. Second, the vibration of rolling bearing in the work to identify and check. The vibration of the rolling bearing is sensitive to bearing damage. For example, in the rolling bearing vibration measurement, there will be a dissection, indentation, the phenomenon such as corrosion, crack and wear, therefore, through the use of special measuring of bearing vibration ( Frequency analyzer, etc. ) Can measure the size of the vibration, abnormal circumstances from deduce the frequency. Because the position of bearing conditions or sensors, measured values are different. Therefore, we need to advance the measured value of the analysis and comparison of each machine, and then determine the standard. The last check the temperature of the rolling bearing. The temperature of the rolling bearing can be deduced from bearing the outdoor temperature. If oil hole can directly measure the temperature of the bearing outer ring, is more appropriate. In general, the temperature of the rolling bearing increased, in 1 - After 2 hours to reach steady state. The normal temperature of rolling bearing and the machine heat capacity, heat dissipating capacity, speed and load changes. If the lubrication, proper installation, bearing temperature rise rapidly, abnormal high temperature, you must stop, take the necessary preventive measures. Due to temperature influenced by lubrication, speed, load and environment, in the table of values only expresses the general temperature range. Using the thermal detector, may at any time to monitor the bearing operating temperature, when the temperature exceeds e. automatic alarm or stop to prevent the shaft accidents.
