Embodiment
Hereinafter with reference to relevant drawings, a kind of fan and rotor structure thereof according to the utility model preferred embodiment are described, wherein components identical will be illustrated with identical reference marks.
Please refer to shown in Figure 2ly, a kind of fan 2 of the utility model preferred embodiment comprises a rotor structure 30 and a stator structure 40.Rotor structure 30 comprises a rotating shaft 31 and a magnetic conduction shell 32, and first end 311 of rotating shaft 31 combines with magnetic conduction shell 32, and second end 312 of rotating shaft 31 is arranged in stator structure 40.Wheel hub 33 is set in outside the magnetic conduction shell 32, and outer rim is equipped with a plurality of flabellums 34.Fan 2 can be an internal rotor fan or an external rotor fan, and the axial flow fan with an external rotor is the example explanation in the present embodiment, and is right non-in order to restriction the utility model.
Hold, magnetic conduction shell 32 comprises a roof 321, a sidewall 322 and a fixing part 323, fixing part 323 forms with punching press, and fixing part 323 rings are established a counterbore 324 (seeing also the A in Fig. 3) of roof 321 centre, sidewall 322 is located on the periphery of roof 321, and roof 321, sidewall 322 and fixing part 323 are formed in one.The material of magnetic conduction shell 32 is a metal or alloy, and in the present embodiment, the material of magnetic conduction shell 32 is that ferrous metal constitutes.
Please refer to shown in Fig. 3 A and Fig. 3 B, it is the magnetic conduction shell 32 of Fig. 2 and the cohesive process of rotating shaft 31.For improving adhesive strength and the associativity between rotating shaft 31 and the fixing part 323, be formed with at least one inclined-plane or at least one lead angle in fixing part 323 outer rims, in the present embodiment, fixing part 323 outer rims are an inclined-plane.Earlier rotating shaft 31 is placed in the counterbore 324 of magnetic conduction shell 32 during assembling, passes rotating shaft 31 with a tool T again, this moment, tool T can import along the inclined-plane of fixing part 323, shown in arrow among Fig. 3 A.Because the inclined-plane provides tool T the preferable angle of exerting pressure, and makes fixing part 323 be able to firm combining with rotating shaft 31, and does not produce the gap, shown in Fig. 3 B.
Please refer to shown in Figure 4, the another kind of fan 2a of the utility model preferred embodiment, it comprises a rotor structure 30a, a stator structure 40.2 different persons of fan with Fig. 2 set in advance a depressed part 324 on the roof 321a of magnetic conduction shell 32a, depressed part 324 is arranged at the opposite side of fixing part 323a.So, can avoid because of using tool with fixing part 323a during with rotating shaft 31 riveted joints, roof 321a allows the assembling precision of magnetic conduction shell 32a and for example wheel hub 33 greatly improve because of being subjected to the out-of-flatness phenomenon that the tool impact is caused.And the main structure of fan 2a is identical with said fans 2, does not repeat them here.
In sum, because of according to a kind of fan of the present utility model and rotor structure thereof, push up by magnetic conduction shell The centre of wall directly is extended with fixed part downwards in order to link rotating shaft. Compared with prior art, this reality Can omit existing copper sheathing element with novel, can reduce production costs.
