Abstract :The noise , emitted by some set of the air2compressors at Baosteel ,once suddenly and severely loudened last year.By continuous surveillance and diagnosis ,we indicated the fault ,and asked for halt to prevent the device from continuous worsening and disaster and to make a check. This article makes a thorough discussion about why the responses of the on2line sensors were normal when the tooth broke , and suggests that the accelerometers and current surveillance can be used for the diagnosis of gear faults to improve the monitoring effect .
