The installation form can realize monitoring of the jumping quantity and the vibration signal of the inner gear ring relative to the bearing outer ring, and avoids the influence on data acquisition caused by errors generated by main drive assembly and structural part processing. The acceleration sensor 2 is installed in a prefabricated hole of the bearing inner gear ring, and meanwhile, external protection is well done. The signal transmitting device is integrated in the sensor, and the acquired signals can be transmitted to the main control room through the signal receiving device and the outgoing line which are fixed on the inner side of the driving box, so that the purpose of monitoring the axial vibration of the bearing inner gear ring is achieved.
In this embodiment, the time domain signal collected by the bearing displacement sensor is monitored in real time, and when no abnormality occurs, the normal signal is as shown in fig. 6.

And further, the running attitude of the main bearing is judged by combining the vibration acceleration signal, the displacement signal and the deflection degree of the inner gear ring of the bearing, and the fault early warning of the main bearing is carried out. If the signal continuously increases as shown in fig. 8, the main bearing fault early warning process is performed, as shown in fig. 9. Specifically, when more than 1 sensor has signal overrun, the programmable controller is used for controlling the alarm to give a fault alarm.
Furthermore, the arrangement end face of the sensor can be replaced by the front end face of the main bearing annular gear, namely the real-time monitoring of the motion attitude of the main bearing is realized by monitoring the space attitude of the front end face; the sensor type need not be limited to two different types of sensors (displacement, vibration), and a sensor capable of comprehensively monitoring displacement and vibration signals may be used instead.
The invention can judge the deflection degree of the inner gear ring in real time during the use process of the bearing, and pre-warn the occurrence of local abnormity and overlarge impact load, thereby more accurately and timely finding the fault condition of the main bearing and reducing the construction risk caused by the direct failure of the main bearing.
