[0002] A rotor generally refers to a rotating body supported by bearings. In a three-dimensional flow fan, the rotating shaft and the impeller as a whole can be called the fan rotor. The existing three-dimensional flow fan rotor drives the impeller seat to rotate at high speed through the rotating shaft.

[0003] For the utility model document with the patent application number CN201921182746.3, the utility model discloses a modified three-dimensional flow rotor, including an impeller seat and a circular clamping block. A first limiting hole is opened inside the impeller seat, and a square shaft is sleeved inside the first limiting hole. The outer surface of the impeller seat is fixedly sleeved with an impeller. Both ends of the square shaft are clamped with a rotating shaft through a clamping mechanism, and both rotating shafts are fixedly connected with the square shaft through a fixing mechanism. The beneficial effects of the utility model are as follows: By setting the square shaft and the first limiting hole arranged inside the impeller seat and adapted to the square shaft, the square shaft limits the impeller seat. By setting the clamping mechanism, the square shaft and the rotating shaft are clamped. By setting the fixing mechanism, the square shaft, the impeller seat and the rotating shaft are fixedly connected, so that when the rotating shaft rotates, the four edges arranged on the surface of the square shaft bear the rotating pressure, thereby preventing the impeller seat and the rotating shaft from shaking due to the fact that the fixing mechanism cannot bear the pressure after long-term high-speed rotation, and improving the working life of the rotor.
