Embodiment
In order to make those skilled in the art can understand the technical solution of the utility model better, below in conjunction with accompanying drawing, its embodiment is described in detail:
Refer to Fig. 2, embodiment of the present utility model, a kind of interpolar supporting structure of rotor, rotor comprises several magnetic pole 1 and several coils 2, several coils 2 are sleeved on several magnetic poles 1 correspondingly, an insulation board 3 is close in the opposite flank of every two adjacent coils 2, arrange an interpolar supporting structure between every two relative insulation boards 3, interpolar supporting structure comprises the first supporting bracket 4, second supporting bracket 5, rack body 6, bolt 7, nut 8 and stop washer 9.
First supporting bracket 4 and the second supporting bracket 5 are close on the lateral surface of two relative insulation boards 3 correspondingly, and the bottom of the first supporting bracket 4 and the bottom of the second supporting bracket 5 offer a breach 41,51 respectively accordingly; Rack body 6 is one piece of bakelite plate, and rack body 6 supports the top between the first supporting bracket 4 and the second supporting bracket 5, and a bolt mounting holes is offered at the middle part of rack body 6; The afterbody of bolt 7 is through bolt mounting holes, and the head of bolt 7 is positioned on the upper surface of rack body 6; Nut 8 is arranged on the afterbody of bolt 7, and the radial both sides of nut 8 are connected in the breach 41 of the first supporting bracket and the breach 51 of the second supporting bracket correspondingly; Stop washer 9 is arranged between the head of bolt 7 and the upper surface of rack body 6.Stop washer 9 is single ear anti-motion washer.
The length of the first supporting bracket 4 is identical with the length of the second supporting bracket 5, and the length of the length of the first supporting bracket 4 and the second supporting bracket 5 is 4/1 to five/2nds of the length of insulation board 3.
Refer to Fig. 3 and Fig. 4, the structure that breach 41, second supporting bracket 5 is offered in the centre of the bottom of the first supporting bracket 4 is identical with the structure of the first supporting bracket 4.
When installing the interpolar supporting structure of a kind of rotor of the present utility model, the afterbody of bolt 7 does not need to be screwed in yoke, the length of bolt 7 is less than the length of the bolt that traditional interpolar supporting structure adopts, first supporting bracket 4 and the second supporting bracket 5 are close on two adjacent insulation board 3 sides correspondingly, the first supporting bracket 4 and the second supporting bracket 5 is compressed correspondingly with the both sides of rack body 6, first supporting bracket 4 and the second supporting bracket 5 respectively have a breach 41, 51, the radial both sides of nut 8 are connected in the breach 41 of the first supporting bracket and the breach 51 of the second supporting bracket correspondingly, so, bolt 7 is more down twisted, first supporting bracket 4 and the second supporting bracket 5 are just pressed tighter, nut 8 just reliably snaps in the breach 41 of the first supporting bracket and the breach 51 of the second supporting bracket, cannot get loose, and nut 8 has held bolt 7, in addition, a single ear anti-motion washer 9 is encased inside between bolt 7 and rack body 6, after bolt 7 is tightened, single ear anti-motion washer 9 turns over all over pinning, fixing, reach whole interpolar mounting system reliably to fix.
The interpolar supporting structure of a kind of rotor of the present utility model is first at job number Z16F1310652, Z16F1310653, Z16F1310654, use in Z16F1310655 TFWS 2218-10 motor, because interpolar location comparison is narrow and small, the pole coil of two interpolars is very little near a few circle interval locations of yoke, between fixed pole, the bolt of support cannot go deep into yoke at all, unless a few circle pole coil bottom chamfer in below, but after chamfering, integral insulation outside pole coil is destroyed, and interpolar position is narrow and small and this kind of motor is marine electric machine, its environment for use is moister, make interpolar more easily creepage, so it is extremely important effectively to insulate.For these reasons, support between the polar this time adopted, the bolt of fixed support body is by coordinating with the fagging of nut and both sides, realize fastening, neither by the impact that interpolar position is narrow and small, can not damage coil insulation again, supporting role effectively can also be played to adjacent pole, and structure is simple and easy to install.
In sum, the interpolar supporting structure of a kind of rotor of the present utility model, can not damage the insulation of coil, can also play supporting role effectively to adjacent pole, and structure is simple and easy to install and can makes full use of locus again, by the narrow and small impact in interpolar position.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the utility model is described, and be not used as restriction of the present utility model, as long as in spirit of the present utility model, all will drop in Claims scope of the present utility model the change of the above embodiment, modification.
