Abstract: Reducer is an important structural component of mine hoist, its normal operation is directly related to the efficiency of
hoist operation. The traditional fault diagnosis method of hoist reducer can only roughly determine the fault type and location, and
the diagnosis effect is not good. The precise fault diagnosis of reducer was realized by using wavelet analysis method, and good
application results were obtained.

Key words: hoist; reducer; fault diagnosis; wavelet analysis method
