Timken bearing regularly inspected by the important role which

In order to determine whether dismantled timken bearings can then use to check the bearing, cleaned, carefully check the raceway, the raceway, with the surface state, cage wear, bearing clearance and the presence on the size of the increase decline in accuracy injury, abnormal.
      timken bearing fault characteristic late to exhibit serious failure (generally axle bearing damage such as burns, sand shelf spallation, raceway, wear beads, etc.) is not more than one week big time, equipment, greater capacity, faster speed, the shorter the interval. Therefore, the actual bearing fault diagnosis, once found fault with advanced features, should decisively determine the bearing is faulty, repair as soon as possible.
     Exercise period of time, to maintain a certain level of vibration and noise, the spectrum is very simple, there is only one or two multiplier. Rarely occurs more than three times the frequency spectrum, bearing condition is very stable, into a stable working period. Continue to run late into the use, bearing vibration and noise begins to increase, sometimes different sound, but the change in vibration increases more slowly this time, suddenly began rolling kurtosis value reaches a certain value. We believe that the performance of the initial point bearing failure.
timken bearing manufacturing popular to go through forging, heat processor, turning, grinding and assembly of multi-channel processing. The reasonableness of the processing technology, advanced, will also affect the stability of the bearing life. Affect the quality of the thermal processor bearing and grinding processes, often with bearing failure have a more direct relationship. In recent years, the bearing surface layer of the study indicate metamorphosis, the grinding process and is closely related to the quality of the bearing surface.
timken bearing life analysis using the primary obligation is based on a lot of information with King, analysis of data and failure style pattern to identify the most important elements constituting bearing failure, so that targeted improvement measures are proposed, delay the decommissioning of rolling bearings, to avoid bearing angry sudden occurrence of early failure.
