Abstract
The utility model discloses fan assembly, including fan blade, rotating shaft and inserts, one end of rotating shaft is provided with annular knurl, and fan blade is set in one end of rotating shaft, and inserts is set in outside rotating shaft, and is embedded in fan blade.It is provided with annular knurl in one end of rotating shaft, bond strength when fan blade is coordinated with rotating shaft can be increased；Meanwhile, it is provided with inserts, and inserts is embedded in fan blade, fan blade and concentricity during rotating shaft assembling can be adjusted by inserts, thus reducing noise during use, reduce rocking during using, improving service life.The fan assembly of this utility model need not be simplified assembling procedure, saved case material, reduces cost using casing and fan blade cooperation positioning.
Description
Technical field
This utility model belongs to a kind of critical piece of electric motor fan, especially relates to a kind of fan assembly.
Background technology
Direct for armature spindle riveting, in assembling, is typically entered rotor casing, due to rotor machine by conventional electric motor fan now
Shell is less with rotating shaft bonded area, and therefore bond strength is difficult to ensure that；Then again riveting is entered the rotor casing press-in injection of rotating shaft
In fan blade, closed with fan blade matching size by casing, realize the connection of rotating shaft and fan blade.This assembling mode is it is difficult to ensure that armature spindle
With the bond strength of fan blade, and both concentricity and degree of balance it is difficult to ensure that, during use, noise is larger, and affects to use the longevity
Life.
Utility model content
The purpose of this utility model is to provide a kind of fan assembly and processing method, can solve the problem that in the problems referred to above extremely
Few one.
According to one side of the present utility model, there is provided a kind of fan assembly, including fan blade, rotating shaft and inserts, rotating shaft
One end be provided with annular knurl, fan blade is set in one end of rotating shaft, and inserts is set in outside rotating shaft, and is embedded in fan blade.
The beneficial effects of the utility model are：It is provided with annular knurl in one end of rotating shaft, when can increase fan blade and rotating shaft cooperation
Bond strength；Meanwhile, it is provided with inserts, and inserts is embedded in fan blade, fan blade can be adjusted by inserts and assemble with rotating shaft
When concentricity, thus reducing noise during use, reduce use during rocking, improve service life.This practicality is new
The fan assembly of type need not be simplified assembling procedure, saved case material, reduce into using casing and fan blade cooperation positioning
This.
In some embodiments, inserts is rounded, is provided with circular hole in the middle of inserts, and the internal diameter of circular hole is more than the outer of rotating shaft
Footpath.Thus, inserts is facilitated to be set in rotating shaft.
In some embodiments, fan blade is moulding.Thus, it is easy to the molding of fan blade, and be easy to inserts to fan blade
Regulation with rotating shaft concentricity.
In some embodiments, the thickness of inserts is 1～1.5mm.Thereby it is ensured that the service behaviour of fan blade, meanwhile,
Save the material cost of inserts, increased the intensity of fan blade simultaneously, improve service life.
Brief description
Fig. 1 is the side structure schematic view of fan assembly of the present utility model；
Fig. 2 is A-A cross section structure diagram in Fig. 1；
Fig. 3 is the mplifying structure schematic diagram of part B in Fig. 2；
Fig. 4 is the insert structure schematic diagram in fan assembly of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4：Fan assembly, including fan blade 1, rotating shaft 2 and inserts 3, one end of rotating shaft 2 is provided with
Annular knurl 4, fan blade 1 is set in one end of rotating shaft 2, and inserts 3 is set in outside rotating shaft 2, and is embedded in fan blade 1.Rotating shaft 2 one end
Annular knurl 4 is Fructus Ananadis comosi shape decorative pattern, increased fan blade 1 when rotating shaft 2 one end is molded, and the compactness that both combine is it is ensured that both connect
The steadiness connecing.
Wherein, fan blade 1 is moulding, and the thickness of inserts 3 is 1～1.5mm, preferably 1mm.
Inserts 3 is rounded, is provided with circular hole in the middle of inserts 3, and the internal diameter of circular hole is more than the external diameter of rotating shaft 2.This circular hole of inserts 3
The multiple aperture of circumferential distribution, is easy to fan blade 1 in injection, inserts 3 is positioned with fan blade injection mold, conveniently repaiies by injection mold
Positive rotating shaft 2 and the perpendicularity of inserts 3, and then, improve the concentricity of fan blade 1 and rotating shaft 2 after injection.
Fan assembly of the present utility model, strengthens the intensity of fan blade 1 by inserts 3, is molded into outside inserts 3 meanwhile
Type fan blade 1 is so that in the rear of the perpendicularity that ensure that inserts 3 and rotating shaft 2 it is achieved that rotating shaft 2 is high with the concentricity of fan blade 1, put down
The good purpose of weighing apparatus degree.
When using, the other end of rotating shaft 2 is connected fan assembly of the present utility model with the output shaft of motor, by electricity
The rotation of machine drives rotating shaft 2 to rotate, and rotating shaft 2 drives fan blade 1 fixed thereon to rotate, and during rotation, stationarity is high.
This fan assembly, ensure that the concentric of rotating shaft 2 and fan blade 1 by the collective effect of inserts 3 and fan blade injection mold
Degree and degree of balance, after injection mo(u)lding, rotating shaft 2 and fan blade 1 coordinate closely, need not using casing and fan blade cooperation realize rotating shaft and
The cooperation of fan blade, decreases the material materials of casing, reduces material cost.
Above-described is only preferred implementation of the present utility model it is noted that ordinary skill for this area
For personnel, on the premise of creating design without departing from this utility model, some deformation can also be made and improve, these all belong to
In protection domain of the present utility model.
