[0002] Precision gears refer to gears that require high precision during the manufacturing process and are usually used in mechanical systems that require high transmission accuracy and low error. They are widely used in aerospace, automobiles, robots, precision instruments and other high-precision equipment. During the manufacturing process of precision gears, the tooth shape, pitch and dimensional errors of the gears must be controlled within a very small range. They usually use high-precision processing equipment, such as CNC machine tools, gear grinding machines, etc., to ensure their accuracy. Precision gears have very high requirements for tooth strength, because the gears bear a large load during the working process and need to maintain stable transmission performance for a long time. The tooth strength detection device of precision gears is used to evaluate the maximum load that key parts such as the gear tooth surface and tooth root can withstand during the working process, and whether the gear meets the predetermined strength requirements. Usually, a certain value of force is applied to the tooth to observe whether the tooth is broken; the precision gear tooth strength detection device in the prior art usually cannot realize batch automatic detection of gears, and the degree of automation is low.
