[0002] Installing bearings on industrial fans is a complex and critical process that requires strict adherence to specific steps and precautions to ensure installation quality and fan performance. A hydraulic fan bearing installation mechanism is a specialized device for installing fan bearings, utilizing hydraulic principles to clamp and secure the bearings. This mechanism typically includes support columns and a base for fixing and supporting the entire installation system. It comprises a hydraulic unit, a clamping mechanism, and a control system. The hydraulic unit includes components such as a hydraulic pump and hydraulic cylinders to provide hydraulic power. The clamping mechanism, composed of hydraulic rods, connecting rods, sliding rods, sliders, and fixing sleeves, is used to clamp and secure the bearings.

Improper operation may result in personnel injury or equipment damage. Furthermore, the manual placement of the bearing rings is relatively time-consuming and it is difficult to guarantee accuracy and consistency each time, which can affect the efficiency of the entire process and increase production costs.
