Inspection of SKF bearing vibration and temperature

1, the vibration of the bearings SKF bearing vibration is sensitive to bearing damage, such as peeling, indentation, rust, crack and wear will be reflected in the deep groove ball bearing vibration measurement, therefore, through the use of special bearing vibration zhangs gauge ( Frequency profiler, etc. ) Can measure the size of the vibration, through frequency points cannot deduce the abnormal condition in detail. Measured values of bearing or sensor installation position and different using conditions, and thus needs prior to each machine stop after certain discriminant analysis compare measurement value of specification. 2, the temperature of the bearings SKF bearing temperature, average has a bearing on the surface of the outdoor temperature can fathom out, if used oil hole can directly measure temperature of bearing outer ring, is more appropriate. In general, the temperature of the deep groove ball bearing with bearing operation beginning gradually rise, 1 - Two hours later to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If smooth, device is appropriate, bearing temperature will rise sharply, SKF bearing can present abnormal high temperature, then must stop and take the necessary precautions. Using thermal device can monitor the working temperature of bearing, and completes the temperature value beyond the rules automatically alarm or stop to avoid burning shaft accident attack. With high temperature often said bearing is in abnormal conditions. High temperature is also harmful to bearing smooth agent. Sometimes deep groove ball bearing overheating can return to the bearing smooth agent. If the bearing at above 125 ℃ temperature for a long time even move to reduce the bearing life. The reason of high temperature bearing include: smooth lack or fire is smooth, smooth agent. Contains impurities, heavy load, bearing damage, lack of clearance, high friction and oil seal and so on. Thus the continuous monitoring of deep groove ball bearing temperature is necessary, whether measured bearing or other important parts of its own. If be in the running condition of the same conditions, the temperature of any changes to the problem can be said has attack. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, to measure bearing temperature can be accurately and in accordance with ℃ or Fahrenheit temperature unit. The importance of bearing, means that when the damage, will form the equipment downtime, so this kind of deep groove ball bearing should be equipped with best temperature probe. Under normal conditions, SKF bearing to smooth over just smooth or later there will be a natural temperature rise and the last one or two days.
