Description

[0002] It is extremely inconvenient to dock the driving wheel and the driven wheel during installation of the existing gearbox, and the driving wheel cannot be adjusted after assembly, resulting in a poor fit between the driving wheel and the driven wheel, resulting in differences in clearance and hidden dangers; appropriate gear clearance can prevent rigid collision of gears during transmission. If the clearance is too small, the gears are prone to jamming during operation, and the friction between the tooth surfaces will increase sharply, resulting in unsmooth transmission, strong vibration and noise; if the clearance is too large, the gears will have obvious impact during meshing, which will also produce vibration and noise, affecting the normal operation of the equipment. For example, the gear transmission system in the automobile gearbox, the appropriate clearance can ensure smooth power output, smooth gear shifting during vehicle driving, and reduce frustration; reasonable clearance can make the tooth surfaces of the gears evenly contact during meshing, avoiding excessive local force on the tooth surfaces due to unreasonable clearance, making the tooth surfaces more evenly worn, and reducing the transmission friction temperature.
