SKF single thrust ball bearing vibration and temperature tests

1, the vibration of the one-way thrust ball bearings one-way thrust ball bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the SKF bearing vibration measurement, therefore, through the use of special bearing vibration tester ( 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. 2, the temperature of the one-way thrust ball bearings one-way thrust ball bearing temperature, usually have a bearing on the surface of the outdoor temperature can be predicted, if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. Usually, SKF bearing temperature as bearing operation began to rise slowly, 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, the 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 the shaft accidents. With high temperature often said bearing is in abnormal situation. High temperature is also harmful to SKF 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 bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, SKF bearing ring, clearance, high friction and oil seal and so on. So the continuity of SKF bearing temperature monitoring 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. SKF bearing temperature measurement can be regularly with the aid of thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of SKF bearing, means that when the damage cause of equipment downtime, so this type of bearings shall be equipped with best temperature probe. In just under normal circumstances, SKF bearing lubrication or lubrication after there will be a natural temperature rise and the last one or two days.
