Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the present invention is further described:

[0012] As shown in the drawings, a hub for an axial flow fan includes a blade 1, which is characterized in that it is provided with a shaft disk 2, a rim 3, a front pressure plate 4, a rear pressure plate 5 and a blade fixing shaft 6, and the shaft disk 2 is arranged on the wheel. The center of the ring 3, and the axle disc 2 and the wheel rim 3 are coaxial, one end of the axle disc 2 is fixedly connected with the front pressure plate 4 through a fixing bolt and a fixing nut, and the other end is fixedly connected with the rear pressure plate 5 through a fixing bolt and a fixing nut, The front pressing plate 4 and the rear pressing plate 5 are stuck in the rim 3, and the circumferential array of the rim 3 has blade installation holes, so as to be beneficial to arbitrarily adjust the angle of the blades. There are positioning holes, which are also conducive to clamping and fixin...
