Abstract
The utility model discloses a novel fan blade which comprises a fan blade base, wherein a group of blades are fixed on the fan blade base; a groove with a polygonal cross section is formed in the center of the fan blade base; a limiting piece matched with the groove in shape and size is arranged in the groove; and a mounting hole connected with a motor spindle is formed in the limiting piece. According to the utility model, through reasonable layout of the components such as the fan blade base, the blades, the groove, the limiting piece, the mounting hole, an axle hole and the like, the strength of the novel fan blade disclosed by the utility model can be effectively improved, the service life is prolonged, the production is facilitated, the production cost is reasonably lowered, and the economic benefits are increased.
Description
Technical field
The utility model relates to a kind of fan part, especially a kind of flabellum of fan.
Background technique
Fan is a kind of instrument that is used to dispel the heat, and is to rely on mechanical energy to change the surrounding environment draught head to realize the air draught air-out.The application area of fan is very wide, comprises fields such as building, factory, mine, boats and ships, automobile, chiller plant, modern instrument equipment and electronic product.At present, the structure of fan on the market comprises motor, main shaft and flabellum.Wherein the flabellum overwhelming majority is injection molded, and main shaft adopts metal material to make; During installation, flabellum is fixed on the main shaft, rotates by the motor driven main shaft, realizes the air draught air-out.Though flabellum adopts and injection moldedly can save cost, its material hardness and intensity aspect are lower, and under the high load continuous running, become flexible easily, break or even come off in the position that is connected with main shaft on the flabellum, cause the fan can't proper functioning.In addition, there is the small part flabellum when injection moulding, to put into metal reinforced sheet integrated injection molding on the market, though can improve the intensity of flabellum like this, but production process is loaded down with trivial details, and it is wayward for the position of metal reinforced sheet when injection moulding, yield rate is low, causes fabricating cost too high, is difficult to extensively promote the use of.Therefore, be badly in need of a kind of intensity height occurring, cost is low, and is convenient for production, the novel flabellum of long service life.
The model utility content
The utility model will solve the problem that above-mentioned prior art exists, and a kind of intensity height is provided, and cost is low, and is convenient for production, and the novel flabellum of long service life is met the need of market.
The utility model solves the technological scheme that its technical problem adopts: this novel flabellum, comprise the flabellum pedestal, be fixed with one group of blade on the flabellum pedestal, it is polygonal groove that flabellum pedestal center has cross section, be provided with the banking stop that shape size and groove are complementary in the groove, this banking stop is provided with the mounting hole that is used to connect motor spindle.Like this, when producing, get final product molding and forming, only need the supporting banking stop of each flabellum when dispatching from the factory as long as on injection mould, install a module additional with size such as this banking stop, not only convenient for production, also help the saving cost; In addition, when installing and using, the banking stop that only needs to be equipped with is installed in the groove, mounting hole on motor spindle and this banking stop is connected and fixed gets final product, because the cross section of groove and banking stop is identical polygon-shaped, banking stop effectively can be limited in the groove, prevents that banking stop is loosening, improve the join strength between motor spindle and the flabellum, prolong the working life of flabellum.
Further, flabellum pedestal center is provided with the axis hole of the motor spindle that is used to peg graft, and this axis hole position and position of mounting hole are complementary.Like this, when flabellum was installed, motor spindle can pass the flabellum pedestal, improved constant intensity.
Groove cross section and banking stop cross section all are the decussate texture setting.Like this, can promote mutual spacing effect between banking stop and the groove.
The flabellum pedestal comprises outer ring, inner ring, and in outer ring outer wall, all be located on the inner ring by groove, banking stop, axis hole around array for described blade ring, and the outer ring is connected and fixed by stiffening rib sheet and inner ring.Like this, can under the prerequisite that does not reduce the flabellum bulk strength, suitably reduce materials, can save production cost.
The one-body molded setting of flabellum pedestal.Like this, can make things convenient for rapid batch production.
Banking stop is a tinsel.Like this, can adopt metals such as iron plate, steel disc and copper sheet to make banking stop, improve the non-deformability of mounting hole, increase the service life.
The effect that the utility model is useful is: of the present utility model rational in infrastructure, compact, rational deployment setting by parts such as flabellum pedestal, blade, groove, banking stop, mounting hole and axis holes, can effectively improve intensity of the present utility model, prolonged its long service life, not only convenient production, can also rationally reduce cost of production, increase economic efficiency.

Description of reference numerals: flabellum pedestal 1, outer ring 1-1, inner ring 1-2, blade 2, groove 3, banking stop 4, mounting hole 5, axis hole 6, stiffening rib sheet 7.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to accompanying drawing: this novel flabellum in the present embodiment, comprise flabellum pedestal 1, be fixed with one group of blade 2 on the flabellum pedestal 1, it is polygonal groove 3 that flabellum pedestal 1 center has cross section, be provided with the banking stop 4 that shape size and groove 3 are complementary in the groove 3, this banking stop 4 is provided with the mounting hole 5 that is used to connect motor spindle.
Further, flabellum pedestal 1 center is provided with the axis hole 6 of the motor spindle that is used to peg graft, and these axis hole 6 positions and mounting hole 5 positions are complementary.
Groove 3 cross sections and banking stop 4 cross sections all are the decussate texture setting.
The 1 one-body molded setting of flabellum pedestal.
When the utility model uses, banking stop 4 is socketed on the motor spindle, again banking stop 4 is got final product with groove 3 corresponding installations on the flabellum pedestal 1.Or banking stop 4 is installed in the groove 3 on the flabellum pedestal 1, mounting hole 5, axis hole 6 are aimed at the motor spindle sockets, main shaft is fixed getting final product by fastening pieces such as nuts with flabellum pedestal 1, quick and easy for installation.The utility model intensity height, cost is low, and is convenient for production, and long service life is worthy to be popularized.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
