Problems solved by technology
[0024] In the face of a large number of failures such as cracks in gearboxes and related components, several established international manufacturers are helpless: neither can they automatically identify serious failures that have occurred, nor can they identify the cause of the failure, let alone propose to avoid existing gearboxes. Countermeasures for rapid occurrence and rapid expansion of faults such as components

The invention relates to a resonance rupture automatic reconnoitering, identification and prevention monitoring method for a gear case and transmission system. The main structure comprises a rotating speed sensor S installed on a gear shaft, vibration shock detection sensors A installed on bearing pedestals of a gear case and an on-line monitoring device JKQ. The on-line monitoring device JKQ is connected with all the sensors and acquires vibration shock signals detected by the sensors and corresponding acceleration and resonance demodulation signals in a parallel manner, and carries out rotating speed tracking, and outputs analyzed and decided control information. By employing the Resonance rupture automatic reconnoitering, identification and prevention monitoring method for the gear case and transmission system, present common faults of gear transmission systems of high-speed railways can be discovered timely, the reasons of the faults can be found out, monitoring measures can be taken in real time, the failure rate of the existing gear case and transmission system can be reduced, an improved machinery system can be obtained, and the gear case and transmission system can be guided to operate safely.
Description
technical field [0001] The invention relates to a method for automatic reconnaissance, identification, prevention and monitoring of a gearbox and transmission system rupture. The invention belongs to the technical field of safety monitoring of sports machinery equipment. It is mainly used in the gear transmission system in the field of high-speed rail operation. During the movement of high-speed rail trains, it can identify the resonance frequency of the gearbox and transmission system by monitoring the relationship between the vibration acceleration, speed and vibration frequency of the gearbox and transmission system including bearings and gear parts. Resonance speed and resonance vibration acceleration, so that according to the vibration acceleration limit value, the control countermeasures for changing the speed, avoiding resonance, and reducing vibration to prevent resonance cracking are put forward, and then according to the crack opening and closing impact caused by the...
