Oscillation of imported bearings has an obvious effect on the failure of bearings. For example: spalling, indentation, corrosion, cracks, wear, etc. will be reflected in the imported bearing oscillation detection, so through the use of special imported bearing oscillation measurement equipment (frequency analyser and oscillator, etc.) can be measured by the size of the oscillation, through the frequency distribution can be deduced from the specific circumstances of the abnormal oscillation, the measured value due to the use of imported bearings, or the sensor device orientation and so on, and thus the need for prior The measured value of each machine is analysed and compared to determine the standard imported bearings.
Usually the temperature of imported bearings with the beginning of the work slowly rise, 1 to 2 hours after reaching a stable condition. The normal temperature of imported bearings due to the machine's thermal capacity, heat dissipation, speed and load and different, if the lubrication, device is not appropriate, the import bearing temperature will rise sharply, there will be anomalous high temperature, it is necessary to shut down and adopt the necessary precautions.
Smooth to rolling import bearing fatigue life and conflict, wear, temperature rise, vibration, etc. has an important impact, no normal smooth, import bearing can not work. Analysis of the causes of damage to imported bearings indicate that 40% of the imported bearing damage are related to poor smooth. Therefore, INA bearing outstanding smooth is to reduce the import bearing conflict and wear useful measures.
