Gear is a commonly used part and has a wide range of applications in various fields. For some large or super-large equipment, the load of the equipment is very large, so the gears in the equipment are often large in size and quality, and the cost of materials, processing, and transportation of such large gears is very high. Although the volume and quality of large gears are large, problems such as damage may still occur during use, especially face gears, which are more prone to damage and other problems than other gears. After the large end gear is damaged, if it is directly replaced with a new end gear, it will cause great waste, and it should be replaced or repaired according to the specific damage or defect. For repairable defects, the face gear is usually repaired by means of repair. Before repairing the face gear, it is necessary to clean the face gear thoroughly to avoid adverse effects caused by incomplete cleaning on subsequent repairs.
