In the utility model, the inner side end of wheel hub is the end face near motor one side, and the outside end face of wheel hub is the end face away from motor one side.The original metal inserted piece of cancellation in the wheel hub, be that wheel hub is the plastic monoblock molding and forming, after assembling, the injection-moulded plastic of the end face of integral molded plastic wheel hub directly contact with axial limiting mechanism and with wheel hub spacing (in the prior art, the metal inserted piece that the fan blade wheel hub passes through its end face contact with axial limiting mechanism and with the fan blade axial limiting); In the utility model, cancelled metal inserted piece, can satisfy the assembling intensity of fan blade and motor equally, the effect of bringing thus is: make that the used mould of fan blade injection moulding processing is simplified, die life is improved, the fan blade Shooting Technique is simpler, injection moulding efficient height.
Further improvement of the utility model is:
Be provided with boss near described wheel hub inner side end and constitute described inner side limiting-position mechanism on described output shaft, this boss is with described wheel hub inner side limiting-position.Carry out spacing, simple in structure by the boss on the output shaft to the inboard of described wheel hub.
Be connected with nut near described wheel hub outside end face and constitute described outside position-limit mechanism on described output shaft, this nut is spacing with the described wheel hub outside.By nut axial limiting is carried out in the wheel hub outside, spacing reliable, mounting or dismounting are convenient.
Described outside position-limit mechanism also includes pad, and this pad is located between described nut and the described wheel hub outside end face.After adding pad, can increase area of contact, reduce the stress of wheel hub outside end face, improve intensity.
Near described nut place, described wheel hub outside end face indent and form heavy stand.When assembling, nut or pad can partly place in this heavy stand, in order to avoid nut or pad withdraw from, make spacing more reliable.
Described heavy stand is with respect to 1 to 2 millimeter of described wheel hub outside end face indent.Alap heavy stand is set herein, can avoids nut or pad to withdraw from, simultaneously, also further improve assembling intensity.
Described wheel hub comprises inner wheel hub, the outer wheel hub of coaxial setting, is provided with stiffening rib between inner wheel hub and outer wheel hub.Being provided with of stiffening rib can reduce the used material of injection moulding, also can guarantee the intensity of wheel hub.
Described stiffening rib is circumferentially uniform between described inner wheel hub and outer wheel hub.Stiffening rib is circumferentially uniform, can guarantee that wheel hub intensity is even, running is steady.
Described stiffening rib is 3 to 5.Stiffening rib is set to 3 to 5, both can guarantee the intensity of wheel hub, is unlikely to make the injection moulding course of working of wheel hub too complicated, reasonable in design again.
Also it should be noted that: in the utility model herein, described wheel hub has been cancelled metal inserted piece, be the integral molded plastic moulding, but and be not precluded within injection moulding and add man-hour, this wheel hub can be finished with the other parts structure injection moulding of fan blade, as as required, can be with the blade and the whole integral molded plastic moulding of wheel hub of fan blade, this is according to the needs of actual design.
To sum up, the utility model has the advantages that:
1, cancelled the wheel hub metal inserted piece, made the fan blade injection moulding add mould simplification in man-hour;
2, improve the working life of fan blade injection mould;
3, simplify fan blade injection moulding processing process, injection moulding efficient height;
4, axial limiting mechanism is simple in structure, and is spacing reliable;
5, the reasonable in design of stiffening rib is simplified wheel hub structure when can satisfy intensity.
