Problems solved by technology
If the horizontal assembly is adopted, it is necessary to solve the centering accuracy of the notch and the deviation during the lateral movement process, and it is difficult to ensure the smooth assembly of the notch in the end
[0004] During the assembly process of the wind tunnel compressor rotor, the inlet side shaft or the outlet side shaft of the compressor rotor must first pass the dynamic balance test, and then be assembled with the hub of the compressor. The weight and size of the outlet side shaft are too large to test it with the existing dynamic balancing method

Embodiment Construction
[0032] The specific implementation of the wind tunnel compressor rotor shaft balancing mechanism and the shaft balancing method of the present invention will be described below with reference to the accompanying drawings.
[0033] Such as figure 1 As shown, the schematic diagram of the rotor mechanism of the large compressor described in the present invention, the first-stage hub 102 is formed after the first-stage hub and the second-stage hub are welded, the second-stage hub 103 is formed after the third-stage hub and the fourth-stage hub are welded, and the first section After the hub 102 and the second segment hub 103 are fastened and fixed by bolts at the seam position, they constitute the overall hub of the compressor rotor. The two ends of the hub are respectively installed with the outlet side shaft 100 and the inlet side shaft 101, and the outlet side shaft 100 is connected with the hydraulic pressure. After the cylinder 104 is fitted and installed, the hydraulic cylin...

The invention discloses a shaft balance mechanism of a wind tunnel compressor rotor. The shaft balance mechanism comprises a balance body; a balancer mounting shaft is fixedly connected to one end ofthe balance body and a flange is fixedly connected to the other end of the balance body; and the flange is used for connecting an inlet side shaft or outlet side shaft of a wind tunnel compressor rotor. In addition, the invention also discloses a shaft balance method. According to the method, the inlet side shaft or outlet side shaft are assembled vertically by using the shaft balance mechanism, so that the inlet side shaft or outlet side shaft completes dynamic balance testing successfully.
Description
technical field [0001] The invention relates to a balance testing device for components in a pressure wind tunnel compressor rotor, and in particular relates to a wind tunnel compressor rotor shaft balance mechanism and a balancing method on the air inlet and outlet sides of the wind tunnel compressor rotor. Background technique [0002] Wind tunnel compressors are large-scale compressor equipment. Their rotors have complex structures, many parts, large dimensions, and a weight of 50-80 tons. At present, there are no relevant standards for the design, manufacture and inspection of wind tunnel compressor rotors. The rotor is multi-component spigot positioning, and the size and weight of each single piece are super-large components in related fields, and the design requires high positioning accuracy. [0003] Due to the large size of the positioning spigot (φ1500-2500mm) and high positioning accuracy (0.10-0.20mm positioning gap), the assembly scheme has no reference experienc...
