[0002] A gear shaft is a mechanical component that combines both gears and a shaft, mainly used to achieve the transmission of power and torque in a transmission system. It is usually made of high-strength materials such as alloy steel to withstand a working environment of high-speed rotation and high load.

[0003] The design of the gear shaft combines the functions of a gear and a shaft: on the one hand, through the gear part meshing with other gears, the transmission and adjustment of power are achieved; on the other hand, through the shaft body part, it supports rotating parts and bears radial and axial loads.
