Embodiment Construction
[0051] Taking the monitoring of the vibration running state of a certain type of rolling bearing as an example, the present invention will be further described in detail in conjunction with the accompanying drawings and examples. The rotational frequency of the shaft where the bearing is located is 3.795 Hz, and the characteristic frequencies of each component of the bearing are shown in Table 1.
[0052] Table 1 Characteristic frequency of bearing components
[0053]
[0054] like figure 1 As shown, taking the inner ring of the rolling bearing as the monitoring object, a method for extracting the condition monitoring index of the rotating equipment based on the vibration energy gradient decomposition includes the following steps:
[0055] 1) Collect the first several groups of vibration monitoring data in the smooth running period of the rolling bearing inner ring, decompose the vibration monitoring data in the smooth running period into several levels of sub-signals based...
