Description

Rotor convenient to dynamic balance Technical Field The utility model belongs to the technical field of water pump manufacturing, and particularly relates to a rotor convenient for dynamic balance. Background The rotor has uneven mass distribution due to uneven material, processing error, assembly deviation or running abrasion, and generates centrifugal force during rotation. The unbalanced force can cause vibration, accelerate bearing abrasion and even cause equipment failure, the existing rotor is often corrected by removing weight or balancing weight at the high end of the next year, the existing rotor is coated with high polymer coatings such as silicone rubber, fluororubber, polytetrafluoroethylene and the like at the two ends for sealing, the density of the materials is low, and dynamic balance is difficult to carry out by cutting the high polymer coatings. Disclosure of Invention The present utility model has been made keeping in mind the above problems occurring in the prior art, and an object of the present utility model is to provide a rotor which is convenient for dynamic balancing. The rotor convenient for dynamic balance comprises a rotor body, wherein the rotor body comprises a shell, a rotor assembly and two metal plates, the two metal plates are arranged at two ends of the shell, and the metal plates and the shell are used for sealing the rotor assembly. The rotor assembly is sealed by matching the metal plate with the shell to replace a macromolecule convex layer, so that the invasion of external impurities is prevented, the service life is prolonged, meanwhile, the dynamic balance of the rotor is carried out by punching holes in the metal plate, the dynamic balance is simpler to adjust, and meanwhile, the process difficulty for manufacturing the rotor is reduced. In the rotor facilitating dynamic balance, the metal plate is circular, and the side wall of the metal plate is welded with the shell. In the rotor facilitating dynamic balance, the metal plate is provided with a through hole for the rotor assembly to pass through, and the through hole rotor assembly is welded. In the rotor facilitating dynamic balance, the metal plate is made of stainless steel. In the rotor convenient for dynamic balance, the side wall of the metal plate is provided with a yielding slot for the insertion of the shell. In the rotor facilitating dynamic balance, a chamfer is arranged on one side of the slot. Compared with the prior art, the utility model has the advantage of being convenient for dynamic balance adjustment of the rotor.
