Diagnostic Study on the Fault of Cut-Off Drum Bearing of Roller Type Coal Mining Machine
Aiming at the situation that the cut-off drum bearing of drum-type coal mining machine is prone to failures,a drum bearing fault diagnosis method is introduced by taking TD75 drum-type coal mining machine as an example.The diagnostic method adopts four indicators,namely,crag,smoothing factor,autocorrelation function and energy,to comprehensively determine whether the drum bearing is faulty through the acquisition,screening,synthesis and band-pass filtering of bearing vibration signals,so as to provide support for rapid diagnosis and treatment of faults,which is conducive to the improvement of the operational efficiency of the whole drum coal mining machine,and confirms that the diagnostic method has a certain value of application.
