The bottom surface side of wind wheel ontology is in inner concavity, corresponds to the end face side of wind wheel ontology in the shape that raises upward.
The quantity of the wind wheel leaf is 36, and is distributed evenly on point periphery for discussing ontology, wind wheel Ye Shangfen
It She You not the first rounded corners, the second rounded corners and third rounded corners.
Outer diameter R1=the 7-9mm, internal diameter r1=4-6mm of first rounded corners of first rounded corners.
Outer diameter R2=the 7-9mm, internal diameter r2=19-22mm of second rounded corners of second rounded corners.
Outer diameter R3=the 21-24mm, internal diameter r1=24-27mm of first rounded corners of the third rounded corners.
The beneficial effects of the utility model are:
Since aluminium core is cylindrical hollow structure, and flat position portion is by being integrally formed with bottom plate, without in aluminium core
Inner cavity additionally flat position portion is processed, simplify processing program, reduce production cost.
The additional aspect and advantage of the utility model will become obviously in following description section, or practical new by this
The practice of type is recognized.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model embodiment.
Fig. 2 is the exploded view of the utility model embodiment.
Fig. 3 is the structural schematic diagram of the utility model embodiment wind wheel leaf.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to figures 1-3, the low wind wheel of this aluminium core manufacturing cost, including wind wheel ontology 1 and wind wheel leaf 2, wind wheel ontology 1
Center be equipped with for the aluminium core 11 with motor axis connection, wind wheel leaf 2 is set to the periphery of wind wheel ontology 1 centered on aluminium core 11
On, aluminium core 11 is cylindrical hollow structure, and the bottom plate 12 of aluminium core 11 is correspondingly connected with hole 121 with connecting hole 121, bottom plate 12 is equipped with
Position is equipped with the flat position portion 122 extended to the inner cavity of aluminium core 11, and flat position portion 122 passes through with bottom plate 12 to be integrally formed, by
In aluminium core 11 be cylindrical hollow structure, and flat position portion 122 be by with bottom plate 12 be integrally formed, without in aluminium core 11
Inner cavity additionally processes flat position portion 122, simplifies processing program, reduces production cost.
Further, between flat position portion 122 and the inner cavity of aluminium core 11 be equipped with reinforcing prop 13, improve flat position portion 122 with it is interior
Structural strength between chamber keeps motor shaft and the connection in flat position portion 122 more stable.
Further, between the outside of aluminium core 11 and wind wheel ontology 1 be equipped with several reinforcing ribs 14 improve aluminium core 11 with
Structural strength between wind wheel ontology 1.
Further, wind wheel ontology 1 is equipped with empty avoiding curved surface 15, and empty avoiding curved surface 15 is equipped with several anti-shrinkage muscle 151,
The bottom surface side of the corresponding wind wheel ontology 1 of anti-shrinkage muscle 151 is in inner concavity, corresponds to the end face side of wind wheel ontology 1 in upward convex
Shape is played, anti-shrinkage muscle 151 can play the role of increasing surface area, when beginning to cool contraction after the completion of wind wheel injection molding, relatively
Empty avoiding curved surface 15 it is smooth, and due to one end of anti-shrinkage muscle 151 be in inner concavity, the other end is convex, and what wind wheel was subject to answers
Power is concentrated on the position of anti-shrinkage muscle 151, so that reducing wind wheel integrally occurs the possibility for cracking or deforming, is promoted and is produced
Quality.
