[0002] A gear refers to a mechanical element with gears on the wheel rim that continuously mesh to transmit motion and power. According to its structure, gears can be divided into gear teeth, tooth grooves, end faces, normal faces, tooth top circles, tooth root circles, base circles, pitch circles and other parts. A reducer is an independent component composed of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine.

[0003] Through patent search, it was found that a gear meshing degree detection device with publication number CN217818453U can facilitate disassembly and adjustment between the U-shaped part and the support rod through the sleeve, connecting hole and fixing bolt, that is, loosen the fixing bolt to leave the connecting hole, and drive the U-shaped part etc. to move up and down to the required position as required and fix it by tightening the fixing bolt, so that it can adjust the relative position of the U-shaped part etc. to adapt to the test gear fixation requirements. The above-mentioned comparative document needs to use multiple sets of U-shaped parts and use bolts to limit the required detection size. The operation is more cumbersome and there are certain limitations in its use. Utility Model Content
