Live test of toothed mechanical obstacles
Defective frequency defects, making an accurate judgment of the nature of the fault. Accurate diagnosis of gearbox failures can save time and cost for on-site production; shaped seals are a common sealing element with reliable sealing, simple sealing parts, easy disassembly, low motion friction resistance, etc. Widely used in.
When the noise of the gearbox is increased, the actual experience of the workers is used to eliminate the possibility of bearing failure. The analysis of the monitoring system is shown in the figure. It can be seen from Fig.* that there is an abnormal peak on the cepstrum of the fault signal, which is much larger than the amplitude of the other points, and both of them are about the scrambling frequency. After calculation, the characteristic frequency of the pinion of the output stage is basically matched, and the pinion gear of the output stage can be seen. Because of the force is a common point of failure. It can be seen from the figure * that the scrambling method is less affected by the propagation path.
It can be seen from the figure / after the gearbox has been running for a period of time, when the gear has a fault, the amplitude is obviously increased as shown in Figure 567. When there is fatigue spalling and crack defects, the cross-correlation is obvious in the difference. Abnormal amplitude and period (as shown in Figure /597), at this time make a quick and accurate judgment, make necessary preparations for timely replacement and repair of gears, saving diagnosis and repair time, and reducing costs for enterprises. This method is accurate and intuitive.
