The gear meshing sound detection module is equipped with a sound broadcasting device, a first sound collecting device, a second sound collecting device, and a third sound collecting device; the transmission shaft vibration collection module is equipped with a sound attenuation device. The present invention improves the detection accuracy by arranging a cup-shaped sound collecting device at the meshing position of each gear and connecting the cup-shaped sound broadcasting device equipped with an acoustic emission sensor through a tube, thereby realizing comprehensive monitoring of the wear status of the gears, integrating a gyroscope, and performing angular velocity detection on the transmission shaft to cooperate with the detection of the acoustic emission sensor and the vibration sensor, and multi-sensor fusion is used to improve the detection accuracy and avoid the instantaneous error of a single sensor.

At this time, due to the wear of the tooth surface of the gear, the measuring block 402 will move counterclockwise, and the displacement distance of the measuring block 402 is in a certain proportion to the rotation angle of the pointer 408, and the smaller the wear degree of the gear, the smaller the distance the extrusion measuring block 402 moves. Therefore, at this time, people can clearly understand the gear by watching the pointer 408 pointing to the value on the data table 407. The wear degree of the wheel, each data table 407 can correspond to the wear degree of each tooth on the gear according to the actual situation, and then the data is manually recorded, and then the pressing frame 601 is released, the fourth spring 603 and the fifth spring 606 are restored to their original state, first driving the pressing frame 601, the support rod 701 and the sliding rod 702 to move upward and reset, the sliding rod 702 drives the slide cylinder 703 to reverse, the slide cylinder 703 drives the pressing block 607 to reverse, the pressing block 607 drives the lower pressing block 506 to reverse, thereby driving the central axis 3 and the contact block 504 to reverse, the contact block 504 can drive the gear to reverse and reset, and then drive the fixing rod 604, the second slider 605, the pressing block 607 and the slide cylinder 703 to move upward and reset, so that the pressing block 607 is separated from the lower pressing block 506,The third spring 507 returns to its original state, driving the lower pressing block 506 to move upward and reset, and the lower pressing block 506 drives the top block 508 to move upward and reset, so that the top block 508 releases the first slider 502, and the second spring 503 returns to its original state, driving the first slider 502 and the contact block 504 to move inward and reset, so that the contact block 504 releases the gear, and then the gear that has been tested is manually taken out, at this time the gear will be separated from the measuring block 402, the first spring 403 returns to its original state, driving the measuring block 402 to slide and reset in the counterclockwise direction, the measuring block 402 drives the driving tooth 404 to slide and reset in the counterclockwise direction, the driving tooth 404 drives the spur gear 405 to reverse, the spur gear 405 drives the rotating rod to reverse, and the rotating rod drives the pointer 408 to reverse and reset through the meshing of the bevel gear 406, and the above operation can be repeated to detect the wear degree of the gear again.
