Embodiment
Below in conjunction with accompanying drawing, multifunctional fan blade wheel hub of the present invention is described in further detail.
As shown in Figure 1 to 4, multifunctional fan blade wheel hub of the present invention, comprising: hub body 1 and be arranged in the axial blade 2 on hub body 1 outer peripheral surface.On the inwall of hub body 1 circumference, be provided with the even spaced centrifugal blade 3 of multi-disc, the centrifugal blade 3 long limit of an axial side itself is fixed with the inwall of hub body 1 circumference, the draw-in groove 4 that axially opposite side is provided with by one end and outer annular-stiffer 5 connects and fixes or direct and outer annular-stiffer 5 and hub body 1 one-body molded.Centrifugal blade 3 can be to armature winding (heating piece) heat radiation, the also heat radiation to the electric component such as stator magnetic shoe and brush, inductance simultaneously, and also its shape adopts curved leafly or curvedly plunder combination shape, can make the air quantity of fan increase and reduce noise.
Interior stiffening ring 6 and outer annular-stiffer 5 are all arranged on the inner side of hub body 1 end face, and interior stiffening ring 6 is coaxially arranged in outer annular-stiffer 5.On hub body 1 end face between interior stiffening ring 6 and outer annular-stiffer 5, be provided with multiple equally distributed vent holes 7, in the time that motor rotates, can produce negative pressure, not only can dispel the heat, also for centrifugal blade 3 provides air intake, strengthen the effect of heat radiation.
Meanwhile, stiffening rib 8 and stiffening rib 8 are set between interior stiffening ring 6 and outer annular-stiffer 5 and arrange with vent hole 7 intervals, play the effect of reinforcing.In addition, centrifugal blade 3 also can be used as supplementing of stiffening rib 8, has the effect of reinforcement simultaneously, makes fan blade not yielding.
Boss 9 is arranged on the inner side of hub body 1 end face and is positioned at stiffening ring 6 inside.Meanwhile, on the position corresponding with boss 9, the outside of hub body 1 end face, be provided with groove 11.Can make hub body 1 directly be connected with armature by boss 9, abandon original direct mode being connected with motor shaft single shaft, make each other beat reduce, balance quality is improved.And the quantity of boss 9 can be two or three, can further strengthen like this stability connecting.
In order to improve reliability, protrude 10 in other adding again of boss 9, protruding 10 can directly contact with motor bearings outer ring, and the reliability of armature rotation is promoted again.
Certainly, can on the end face of the hub body 1 between interior stiffening ring 6 and outer annular-stiffer 5, be provided with multiple equally distributed radiating fin 12, as a kind of other heat radiation form.
Multifunctional fan blade wheel hub of the present invention has changed original mode being directly connected with motor shaft single shaft, directly be connected with armature by boss, ensure the stability connecting, make each other beat reduce, balance quality is improved, it can not only cooling surrounding environment for cooperating fan, and by radiation hole or the motor of radiating fin energy effective cooling in hub body inside, reliability and the working life of having improved fan; Without insert, single forming more easily ensures the dimensional accuracy of fan blade.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the invention spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
