We found that in the long-term production status monitoring, rolling bearings exhibit strong regularity in the process, and the repeatability is very good. Normal quality bearings use, vibration and noise are relatively small, but some scat tered spectrum, smaller amplitude may be due to some defect in the manufacturing process, such as surface burr.
Exercise time, vibration and noise to maintain a certain level, single spectrum appears only one, second harmonic. Very rare triple-frequency spectrum above, bearing condition is very stable, to enter stable work period. contact ball bearing
Continue into use late run, bearing vibration and noise begins to increase, sometimes a different tone, but the change of vibration increases more slowly, at this time, bearing kurtosis values start suddenly reaches a certain value. We believe that, at this time the bearing that showed initial failure.
At this time, it requires close monitoring of the bearings, pay close attention to its changes. Thereafter, the bearing kurtosis value decreased rapidly, and close to normal, while the vibration and noise begins to significantly increase, the increase began to accelerate its bearing kurtosis values also began, when the vibration exceeds a vibration standard (such as ISO2372 standard) The rapid increase, when both exceed vibration standards, and kurtosis values than normal (relative standard available kurtosis), we believe that the bearing has entered the late failure of production, and timely maintenance of equipment, replacement of rolling bearings. buy bearing
Bearing showed late failure characteristics to a serious failure (generally bearing damage, such as axle, burns, sand frame Spallation raceway the beads wear, etc.) time it tends to be more than a week, the greater the capacity of equipment, the faster the speed, the The shorter the interval. Therefore, the actual ball bearing fault diagnosis, once found late failure characteristics should be decisive judgment bearing fault, as soon as possible overhaul.
