Check SKF bearing failures in the operation and process methods

We first of all from SKF bearing vibration, scrolling, and temperature on the three aspects, as the effect of bearing lubrication in relatively large, so do as separate chapters we will expand to show:
First check the SKF bearing vibration at work
From corrosion, cracks, spalling, indentation, wear will be reflected in the SKF bearing vibration measurement, vibration damage to the bearings of SKF bearings are very sensitive, so, through the use of special SKF bearing vibration Measurer (frequency Analyzer, etc) can measure the size of the vibration, through frequency cannot be inferred from specific situations of exception. Measured due to the numerical bearing conditions of use or different sensors such as installation location and therefore require prior to analysis and comparison of measurement values of each machine are determined criteria.
Second is to check when SKF bearing rolling sound
Even with minor injuries such as split because SKF bearings, also is making an abnormal sound and irregular sound, using the acoustic measurement can be distinguished using acoustic logging, in the operation of SKF bearing rolling sound and sound to check, played a preventive role in advance.
Last is SKF bearing while rotating to check temperature
If the uses of oil hole can directly measure the temperature of bearing outer ring, the more appropriate. Under normal circumstances, SKF bearing temperature, generally based on the SKF bearing outside of room temperature can be speculative. If lubricated, install appropriate, bearing temperature quick rise, abnormal high temperature occurs, in which case you must stop, take the necessary preventive measures. Generally, SKF bearing temperature as the operation began slowly to rise, reaches a steady state after 1-2 hours. SKF bearing normal temperature due to the heat capacity of the machine, heat dissipation, speed and load to another. If necessary, use heat detector to monitor bearing temperatures at any time, and alarm or stop automatically when the temperature exceeds the specified value prevents burning shaft accident.
