[0002] With the advent of the industrial revolution, the mechanical manufacturing industry is booming, and the precision and reliability requirements of gear transmission are greatly improved. Metal gears gradually replace wooden gears, and the size, shape and transmission ratio of gears become more diversified. During this period, the emergence of machining techniques such as lathes and milling machines enables gears to be accurately manufactured. Correspondingly, gear assembly technology has also begun to develop.

[0003] During the machining of gears, various impurities may be generated, for example, during the cutting process of gears (such as gear milling and gear hobbing), a large amount of metal chips may be generated. These chips may be left on the tooth surface, inner hole or shaft hole of the gear. When assembling the gear, impurities such as sand and metal chips may be trapped between the tooth surfaces of the gear. When the gear starts to operate, the relative movement between the tooth surfaces will cause the impurities to act as abrasives and cause wear on the tooth surfaces. As the gears mesh, the sand will scratch the tooth surface, and these scratches will gradually expand, increasing the roughness of the tooth surface and causing the gear to wear much faster than normal. Therefore, the present application proposes an auxiliary tool for gear assembly. SUMMARY
