Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1, a kind of fan of generator rotor of the utility model, including fan body 10, fan body 10 are set
There are the support holes 11 to be supported on generator rotor shaft；Fan body 10 is equipped with limit fastener 12 and is placed in generator amature phase
So that pawl pole pushes limit fastener 12 fan body 10 is driven to rotate together with when pawl pole rotates between adjacent two pawl poles.
On the basis of the fan of generator rotor of the utility model does not change former claw-pole structure, set using with limit fastener 12
Positioning of the fan on rotor can be realized in the fan of meter, and then achievees the purpose that cancel spot-welding technology, and structure is simple, to setting
Standby no requirement (NR).
Fan body 10 is process by sheet steel, and in order to mitigate weight, energy saving, steel plate thickness is limited, in operation
It was found that being opened outside fan blades oblique angle, intensity is inadequate, is easy to produce deformation, influences air cooling effect when revolving speed is fast.Fan can be big when rotating
Width reduces the vibration of fan blade 13, and then while reducing fan vibration generates noise, improves the comfort that complete machine uses, in order to prevent this
A little situations can be equipped with reinforcing rib 14 at 13 flanging of fan blade on fan body 10.Reinforcing rib 14 can be in U-typed, all two
End is arranged at 13 flanging of fan blade, and side connects with fan body 10.
Limit fastener 12 may include be arranged in along 10 length extending direction of fan body horizontal card division 16 and with horizontal card division
16 vertical foldings are along 17.Generator generally rotates clockwise, and pawl side can push the folding edge of limit fastener 12 when pawl pole rotates
17 drive fans rotate together with.
2 grooves 15 for field coil conductor wiring can be equipped on fan body 10.Two of field coil lead
Line can pass through groove 15 and connect conducting with collector ring.
Limit fastener 12 can be formed by metal plate punching.Fan body 10 may be to pass through stamping forming metal plate
Part.
Limit fastener 12 can be arranged in several ways on fan body 10, herein without limitation, in this implementation
In example, limit fastener 12 and fan body 10 are integrally formed.
It is not directed to place above, is suitable for the prior art.
Although being described in detail by some specific embodiments of the example to the utility model, this field
It is to be understood by the skilled artisans that above example merely to be illustrated, rather than in order to limit the scope of the utility model, this
Utility model person of ordinary skill in the field described specific embodiment can be made it is various modification or
It supplements or is substituted in a similar manner, but direction without departing from the utility model or surmount the appended claims institute
The range of definition.It should be appreciated by those skilled in the art all foundation the technical essence of the utility model are to the above embodiment party
Formula any modification, equivalent replacement, improvement and so on, should be included in the protection scope of the utility model.
