Vibration Fault Diagnosis on Gearbox of Belt Conveyor in Coal Mine

Abstract:

Belt conveyor gearbox is one of key equipments in coal mine which makes sure that the coal mine runs continuously and smoothly. Once it has faults, it will greatly influence the production and the benefits of coalmine. What is more, the raw coal cut by shearer could not be transported to the ground and serious accidents may occur. The authors carry out the vibration monitoring trials on belt conveyor gearbox in an underground coal mine using self-developed mining portable vibration recorder and obtain amount of on-site vibration signal. After analyzing the variation trend of the time domain indexes and power spectrum, we find that the gear of the input shaft of the reducer has severe wear and broken gears. Overhaul results verifies the correctness of the above analysis and the validity of the data sampled by the recorder.
