Abstract

The invention discloses a fan capable of realizing rotor counterweight balance and a counterweight balancing method thereof, wherein the fan includes a rotor, an impeller mounted on the rotor, a diversion cone, a cooling fan and a fastening nut, and the lower section of the diversion cone is connected to the rotor. The upper end of the rotor is screwed together, the cooling fan is installed at the lower end of the rotor, the fastening nut is installed on the rotor and located above the cooling fan, the upper end surface of the impeller is recessed to form a first counterweight screw hole, and the lower end of the impeller The first counterweight ring is integrally formed on the end surface, the second counterweight screw hole is formed in a depression on the lower end surface of the cooling fan, and the third counterweight screw hole is formed on the circumferential direction of the fastening nut. A second counterweight ring is integrally formed in the middle of the solid nut, a first counterweight screw and a second counterweight screw are installed in the first counterweight screw hole, and a third counterweight ring is installed in the second counterweight screw hole. A weight screw, a fourth weight screw is installed in the third weight screw hole.

Description

Technical field: [0001] The invention relates to a fan capable of realizing rotor counterweight balance and a counterweight balance method thereof, which belongs to the technical field of machinery. Background technique: [0002] The rotor in the fan is its core component. When the fan is operating normally, the rotor rotates at a speed of more than 30,000 revolutions per minute. Due to errors in materials, processing, assembly, etc., a newly installed rotor must have a certain imbalance (the central axis of mass does not coincide with the geometric central axis), which will cause the rotor to generate centrifugal force during the rotation. Therefore, after the rotor is assembled, it must be balanced with a counterweight first (test on a dynamic balancing machine, and then subtract some mass or add some mass at certain positions to ensure that the remaining imbalance is within an acceptable range of indicators. Inside). If the remaining unbalance of the rotor does not reach the...
