Abstract

An acoustic fault detection device for a bearing system, which belongs to the technical field of fault detection, is characterized in that an acoustic sensor and an acceleration sensor are used in combination, and an acceleration sensor with strong anti-interference ability is used to detect low-frequency acoustic vibration signals. The intermediate frequency acoustic vibration signal is detected by an electret capacitive acoustic sensor with a large bandwidth, combined with the bearing temperature to process the data in real time, identify the bearing fault, and use the 3G wireless transmission module to send the fault signal to the staff in time, which can diagnose the faults of the bearing at each stage For identification, real-time analysis and processing, and wireless alarm, it has the advantages of compact structure and convenient installation.

Description

technical field [0001] The invention relates to an acoustic fault detection device for a bearing system, which belongs to the technical field of fault detection. The device combines an acoustic sensor and an acceleration sensor and uses an acceleration sensor with strong anti-interference ability to detect low-frequency acoustic vibration signals. The acoustic and vibration signals of intermediate frequency and intermediate frequency are detected by electret capacitive acoustic sensors with large bandwidth, combined with the bearing temperature to process data in real time, identify bearing faults, and use the 3G wireless transmission module to send fault signals to the staff in time, which can realize the detection of bearing system faults online monitoring and wireless alarm. Background technique [0002] In rotating machinery, bearings are the key basic components, but the current problem is that the failure rate of bearings is high. Bearing failure has become one of the ...
