Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, existing wind power generator rotor comprises columned pole core 2, and pole core 2 outer walls are provided with multiple row permanent magnet 1 vertically, multiple row permanent magnet 1 is wrapped with shrink ring 7, and pole core 2 both ends of the surface have adopted the identical integrated end plate holder of structure to hold permanent magnet 1.For such wind power generator rotor, it is comparatively complicated that the installation of permanent magnet 1 just seems, at first the end plate 11 with a side is installed on pole core 2 one side end faces, the permanent magnet 1 of first row is installed then, after the first row permanent magnet 1 installs, the integral type end plate 12 that opposite side can not be installed immediately fixes the first row permanent magnet 1, can hinder pushing and installing of another row permanent magnet like this, therefore must design the proprietary anchor clamps of the many covers of processing and fix the multiple row permanent magnet, after all permanent magnets all install, dismantle all anchor clamps again opposite side integral type end plate 12 just can be installed.This shows that both sides all adopt the integral type end plate to make installation process quite complicated, have also increased cost, this dismounting during to the installation of permanent magnet and maintenance is all totally unfavorable.
Referring to Fig. 2, wind power generator rotor of the present utility model, comprise pole core 2 equally, along the axial multiple row permanent magnet 1 of pole core 2 outer walls, and the parcel permanent magnet 1 shrink ring 7, a side end face of pole core 2 has been adopted all-in-one-piece end plate 4 clamping permanent magnets 1 equally.
Another end face of pole core 2 is provided with one first end plate 5, it comprises a circular bottom plate 51 and the round boss 52 that is arranged on the circular bottom plate 51, a plurality of screws 53 can be set on the round boss 52, it is corresponding one by one with a plurality of screws 21 on being arranged on pole core 2, be fixed on the end face of pole core 2 by screw (not signal) again, this is identical with the previous fixed form of integral type end plate that adopts, and is the mode that those skilled in the art often adopts, and is not repeated at this.
After being installed on the end face of pole core 2, the outline of first end plate, 5 circular bottom plate 51 will be in pole core 2 end faces, in order to avoid influence the installation of permanent magnet 1, optimum execution mode is that circular bottom plate 51 employings adopt concentric to cooperate with the mode of radius with pole core 2 end faces.For mounted permanent magnet 1 is clamped, the edge of first end plate 5 is provided with a plurality of dismountable second end plates 6.
Referring to Fig. 3, Fig. 4, second end plate 6 is step-like, the bottom 62 of lower step 61, and the top 64 of upper step 63, and the junction 65 of lower step 61 and upper step 63 is arc structure, lower step 61 is provided with screw 66.
Referring to Fig. 5, Fig. 6, second end plate 6 matches with first end plate 5, the sidewall (arc radius of bottom 62 is identical with round boss 52 sidewall arc radius) of round boss 52 is close in the bottom 62 of lower step 61, the sidewall (two arc radius are identical) of circular bottom plate 51 is close in lower step 61 and the junction 65 of upper step 63, lower step 61 adopts screws can be fixed on the circular bottom plate 51 by oneself screw 66 and the corresponding screw on the circular bottom plate 51 54 on one's body, upper step 63 is stretched out circular bottom plate 51 can clamping permanent magnet 1, the top 64 of upper step 63 and shrink ring 7 concordant (not illustrating).The thickness of lower step 61 is identical with the height of round boss 52, the thickness difference of upper step 63 and lower step 61 is identical with the thickness of circular bottom plate 51, after the second all end plates 6 was installed on first end plate 5 successively, integral body was a flat configuration, as shown in Figure 6.More convenient for the dismounting that makes every row permanent magnet 1, the quantity of second end plate 6 equates with the quantity of permanent magnet 1.
For the location that makes permanent magnet 1 and fixing more convenient, be provided with every magnetic patch 3 between the multiple row permanent magnet 1, it adopts non-magnet_conductible material, can play damping action.When carrying out permanent magnet 1 assembling, at first will accurately be fixed on pole core 2 outer walls vertically successively every magnetic patch 3, install a side integral type end plate 4 and opposite side first end plate 5 fastening pole cores 2 again, adopt anchor clamps to push from opposite side permanent magnet 1 then, do not push a permanent magnet 1 one second end plate 6 can be installed, the rest may be inferred adorned all permanent magnets 1 in order after, bind no latitude bandage 8 on permanent magnet 1 surface again, and fix permanent magnet 1 at outermost with the stainless steel hot collar 7.When second end plate 6 was installed, in order to save material and to prevent mutual interference, the lower step 61 of second end plate 6 can process chamfering 67 (as shown in Figure 4), guarantees that there is certain clearance in 6 of second end plates.
During maintenance,, do not need the second all end plates 6 is pulled down,, simplified the dismounting and change of permanent magnet like this, reduced cost as long as dismantle second end plate 6 of this row permanent magnet correspondence as need dismounting and change permanent magnet 1.
