Bearing operation process of detection

Bearing rolling sound: the sound device is adopted to the size of the rolling sound of bearing in operation and quality check, even if the bearing has very minor scratches, also an exception and irregular, and measuring the sound device can very good solution to this problem. If the appropriate lubrication, installation department, the bearing temperature will rise sharply, the rise of temperature is not normal, have to stop at this moment, take the necessary precautions. Based on a lot of test data, table 4 - 1 lists the various kinds of mechanical bearing outer temperature averages at work, for your reference. Due to temperature lubrication, rotational speed, load, the influence of environment, the temperature range of values in the table only said roughly. The vibration of the bearing, bearing vibration response to bearing damage or obvious, such as the common problems of indentation, rust, crack, peeling, wear, etc. At the time of testing can clearly feel, so, 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 due to the use of the bearing condition or sensor installation position and different, so need to measurement of each machine beforehand for a certain operation to determine the final data. Bearing temperature: the temperature of the bearing, bearing temperature can be measured, if using the oil hole can directly measure temperature of bearing outer ring, is more appropriate. In general, the temperature of the bearing with operation began to slowly rise, after a few hours to is more stable. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and rotating way will also be different. Using thermal device can monitor the bearing temperature at any time, prior to the accident are preparing and remind.
