Fan shaft refers to the main shaft in the fan to drive the impeller to rotate, produce air flow and achieve ventilation or air supply.

The main function of the fan shaft is to drive the impeller to rotate, so as to produce air flow and achieve ventilation or air supply. Fan shaft is the main component of the fan, and its quality and performance directly affect the stability and effect of the whole machine. In the fan, the fan shaft is driven by the driving device, so that the impeller can rotate at high speed and produce air flow. The fan shaft must have sufficient strength and stiffness to withstand the inertial force and acceleration of the impeller when the airflow is generated, and maintain stability during operation. In addition, the fan shaft also needs to have good wear resistance and corrosion resistance, and can withstand the fatigue and wear caused by high-speed rotation for a long time. At the same time, the fan shaft also needs accurate and reasonable load distribution and symmetry design to avoid vibration and deviation of the shaft during operation. In short, the fan shaft plays a vital role in the fan to ensure the normal operation of the fan and achieve the desired effect.
