SKF Bearing inspection item in rolling bearing sound, vibration, temperature, lubrication condition, as follows:
The rolling sound of a bearing
1.The operation of the size of the audio equipment and sound quality of the sound check of rolling bearings, bearing even slight stripping and other damage to the sound of a normal tone and irregular measurement devices will be to distinguish between sound measurements.
2 bearing vibration
Bearing vibration is very sensitive to bearing damage, such as peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the bearing vibration measurement, therefore, through the use of special bearing vibration measurement (frequency analyzer), measuring the size of the vibration frequency analysis, we can infer that the unusual. Bearing under the conditions of use or installation of the location of the sensor measurement value is different, so each machine needs to predetermined criteria measured value analysis and comparison.
3, the bearing temperature
The temperature of the bearings, general bearings outside the room temperature can be inferred that, if the hole can be used to directly measure the temperature of the bearing outer ring, it is more appropriate. Under normal circumstances, the bearing temperature rise to operate for 1-2 hours, and slowly reaches a steady state. The normal temperature of the heat capacity of the bearing of the machine, heat capacity, speed and load changes. If the inspection and failure to exclude lubrication SKF bearings operation, install the appropriate Ministry, bearing temperature rise will be a sudden, abnormal high temperature, stop running, take the necessary precautionary measures.
