Abstract
The utility model relates to the technical field of axial flow fans, in particular to a wheel hub for an axial flow fan. The wheel hub for the axial flow fan comprises blades and is characterized by further comprising a shaft disc, a wheel ring, a front pressing plate, a rear pressing plate and blade fixing shafts. The shaft disc is arranged in the center of the wheel ring, the shaft disc is coaxial with the wheel ring, one end of the shaft disc is fixedly connected with the front pressing plate through a fixing bolt and a fixing nut, the other end of the shaft disc is fixedly connected with the rear pressing plate through a fixing bolt and a fixing nut, and the front pressing plate and the rear pressing plate are clamped in the wheel ring. Blade installation holes are formed in the periphery of the wheel ring in an array manner so as to facilitate the angle adjustment of the blades at will, positioning holes, corresponding to the blade installation holes, are respectively formed in the front pressing plate and the rear pressing plate so as to facilitate clamping and fixation of the blades, the blade fixing shafts penetrate through the blade installation holes, one side of each blade fixing shaft is fixedly connected with the front pressing plate through the positioning holes in the front pressing plate, and the other side of each blade fixing shaft is fixedly connected with the rear pressing plate through the positioning holes in the rear pressing plate. With the structure, the wheel hub for the axial flow fan has the advantages of being simple in structure, and compact and attractive in appearance, saving raw materials, reducing equipment cost and the like.
Description
Technical field
The utility model relates to the axial-flow blower technical field, specifically a kind of axial-flow blower wheel hub.
Background technique
At present, existing axial-flow blower blade wheel hub all is to be formed by die casting aluminium die casting, and its deficiency is: complex structure, need first die sinking, and carry out complicated mechanical processing again, cause the machining process complexity, bulk strength is not high, the cost height.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, compact appearance is attractive in appearance, save material, reduce the axial-flow blower wheel hub of equipment cost.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of axial-flow blower wheel hub, comprise blade, it is characterized in that being provided with reel, wheel rim, front pressuring plate, rear fender and vanes fixed axle, reel is located at the wheel rim center, and reel and wheel rim concentric, described reel one end is fixedlyed connected with front pressuring plate, the other end is fixedlyed connected with rear fender, front pressuring plate and rear fender are stuck in the wheel rim, described wheel rim periphery circumference array has the blade mounting hole, be beneficial to the angle of any adjusting vane, be respectively equipped with positioning hole on the front pressuring plate of corresponding blade mounting hole and the rear fender, also be beneficial to the blade that is fixedly clamped, the vanes fixed axle passes the blade mounting hole, and the positioning hole of a side on front pressuring plate fixedlyed connected with front pressuring plate, the positioning hole of opposite side on rear fender fixedlyed connected with rear fender, by blade mounting hole and positioning hole, not only can realize fixedly securing blade, but also can realize the function of adjusting vane angle voluntarily.
The utility model is owing to adopt said structure, have simple in structure, compact appearance is attractive in appearance, save material, reduce advantage such as equipment cost.
