Causes of vibration of heavy hammer fan

What are the reasons for the vibration of the heavy hammer fan in use?

Most of the causes of fan vibration are due to the unbalance of the rotor, which is due to the influence of the uneven material, the deviation in the process of processing and assembly, the asymmetry of the structure of the parts and the collision and deformation in the transportation, etc. the center of mass of the rotor does not coincide with the geometric axis of rotation. When the rotor rotates, the unbalanced centrifugal inertia force is generated The greater the inertia force is, the greater the dynamic reaction force of the bearing is, and the stronger the vibration of the heavy hammer fan is, so as to accelerate the wear of the bearing, reduce the service life, increase the noise of the heavy hammer fan, and even cause accidents.
