IKO bearing vibration and temperature of the bearing damage - bearing knowledge

The vibration of a, IKO bearings IKO bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration meter ( Frequency analyzer, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal situation. 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. Second, IKO bearing temperature of bearing temperature, usually have a bearing on the surface of the outdoor temperature can be predicted, if using the oil hole can directly measure IKO bearing outer ring temperature, is more appropriate. Usually, the temperature of the bearing with IKO bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, IKO bearing temperature will rise sharply, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor IKO bearing operating temperature at any time, and realize e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. With high temperature often said IKO bearing is in abnormal situation. High temperature also harmful to the 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 IKO bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuous monitoring IKO bearing temperature is necessary, whether measured bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. IKO bearing temperature measured on a regular basis can use thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. Importance of IKO bearings, means that when the damage cause of equipment downtime, so this type of bearings shall be equipped with best temperature probe. Under normal circumstances, IKO bearings in just after the grease or lubricant will be a natural temperature rise and the last one or two days.
