The wavelets transform algorithm and the characteristics of the wavelets analysis were introduced in this paper,and the wavelet transform used in rol ing bearing fault diagnosis method and the calculation method of rol ing bearing fault characteristic frequency were stated. According to the rol ing bearing vibration characteristics of mine belt conveyor,the gathered field fault vibration signal of mine belt conveyor rol ing bearing was analyzed by using the method of wavelet decomposition reconstruction,and the effectiveness of use wavelet transform to extract the early fault signal of rol ing bearings be improved.
