The actual condition monitoring, often simply to determine the rolling bearing is good or bad, how long can diagnose bearing a site failure, sophisticated analytical and diagnostic practicality is not often. Practical precise diagnosis due to the conditions and other factors, often can not find the the Rolling corresponding characteristic frequency. Although in recent years developed a wavelet analysis and rapid vibration demodulation analysis technique more accurate, but the necessary equipment investment, the need for more analysis of field failure diagnosis typically less application. We take on in the practical diagnosis of dimensionless parameters and dimensionless parameters combine to determine the bearing of rapid fault diagnosis, which adopts the frequency of vibration velocity spectrum analysis, combined with bearing the kurtosis value of a comprehensive diagnosis. When two conditions are more than the standard, we judge that the bearing is defective.bearing company
Such a judgment after three years of practice, proved very useful for rolling bearing fault diagnosis. Judg e the quick and accurate, the accuracy rate of over 90%. The bearings were basically diagnosed in the post-failure stage, with very good economic benefits.bearing manufacturer
In addition, when the monitoring to the rolling bearing very large low-frequency vibration, excluding unit misalignment, imbalance, structural loosening the basis of resonance structural factors, even in the absence of ball bearing characteristic frequency, should be decisive to determine the rolling bearing fault repair.china bearing manufacturer
