To master the key technology of flange bearing FAG common maintenance - bearing knowledge

Flange bearing lubrication in just under normal circumstances, or there will be a natural temperature rise after the lubrication and the last one to two days. Flange bearing stability and performance of the vibration is sensitive to FAG bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the vibration measurement, therefore, through the use of special flange bearing flange vibration tester ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. Measured values for their conditions of use, or sensor installation position is different, so you need to in advance of each machine is analyzed by the measured value of the determined after judgment standard. On the surface of the flange bearing temperature, generally speaking, there are outdoor temperature can be predicted, if using the oil hole can directly measure the flange bearing outer ring temperature, is more appropriate. Generally, the temperature with flange bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. Flange bearing normal temperature due to the heat capacity of the machine, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, FAG bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the bearing temperature at any time, and realize e. automatic alarm when the temperature exceeds or stop to prevent burning high temperature often said bearing is in abnormal situation. High temperature is also harmful to FAG bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature Qingdao flange bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, the load is too large, the flange ring bearing damage, clearance, high friction and oil seal and so on. Flange bearing temperature measurement can be regularly with the aid of thermometer, digital thermometer, for example, can accurate FAG bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of bearing, means that when the damage cause of equipment downtime, so this class should be equipped with best temperature probe. ( 1) And keep the bearing and the surrounding clean. Even the eyes can't see the little dust, also can bring bad influence to FAG bearings. So, keep the surrounding clean, dust from invading bearing. ( 2) , carefully use. In use for bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. ( 3) And use the appropriate operating tools. Avoid to existing tools to replace, must use the appropriate tools. ( 4) , attention should be paid to FAG bearing corrosion. Operation of the flange bearings, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves.
