By driving with other toothed mechanical parts, the gear can achieve functions such as changing the rotational speed and torque, changing the direction of motion, and changing the form of motion. Due to advantages such as high transmission efficiency, accurate transmission ratio, and large power range, gear mechanisms are widely used in automotive products; when gears are produced, according to the usage requirements, holes need to be drilled on their surfaces.
