Gear mechanisms are widely used in mechanical transmissions. However, the gear mechanism is expensive to manufacture and mount, and the low-precision gear transmission is noisy. Gear mechanisms can be divided into two broad categories according to whether the transmission ratio of a pair of gear transmissions is constant: one is a gear mechanism with fixed transmission ratio, the gear is circular, also called circular gear mechanism, is the most widely used one at present, and the other is a gear mechanism with variable transmission ratio, the gear is generally non-circular, also called non-circular gear mechanism, is only applicable in some special machines, according to whether the relative motion of a pair of gears during transmission is plane motion or space motion, the circular gear mechanism can be divided into two types of plane gear mechanism and space gear mechanism.

In the assembly process of the existing gear, a left-handed gear and a right-handed gear of a shaft of a herringbone gear form herringbone teeth and are positioned in the middle of the shaft, and the distance between the two teeth is only a tool withdrawal groove at most.
