When gears perform tasks, they lack working ability due to various complex factors. The value of the functional parameter exceeds the maximum allowable critical value, which leads to a typical gearbox failure. There are also various forms of expression. From the overall situation, it can be mainly divided into two categories: the first category is the gradual generation of gears during the accumulated rotation process. Due to the relatively large load on the outer surface of the gearbox, there will be relative rolling and sliding forces in the clearance between the meshing gears. The frictional force during the sliding process is exactly opposite to the direction of the two ends of the rod. Over time, prolonged mechanical operation can lead to gear bonding, and the occurrence of cracks and increased wear will inevitably result in gear fracture. Another type of malfunction is due to the negligence of the staff during the installation of gears due to unfamiliarity with safety operating procedures or violation of operating norms and requirements, or the hidden dangers planted for the occurrence of the malfunction during the initial manufacturing process. This type of malfunction is often caused by the fact that the inner hole and outer circle of the gear are not on the same center, resulting in shape errors and asymmetric axis distribution in gear meshing.
