Abstract
nullThe utility model discloses a kind of without the design of shaft shoulder armature spindle，Including axle，The left end of described axle is socketed with collector ring，Rear solid end pole it is provided with on the left of the middle part of axle，Fore paw pole it is provided with on the right side of the middle part of axle，It is provided with bobbin in the peripheral space of described fore paw pole and rear solid end pole，Field coil it is wound with on bobbin，Described field coil electrically connects with collector ring，The left side of described rear solid end pole is provided with rear fan blade，The right side of fore paw pole is provided with front fan blade，Described rear fan blade and front fan blade are all connected with axle，It is socketed with back-up ring on the axle on the right side of fore paw pole，This is higher without the versatility that can make axle after the shaft shoulder armature spindle design cancellation shaft shoulder，Rotor assembly wider being suitable for，The back-up ring of multiple different-thickness or diameter can be placed，And facilitate follow-up rotor metalworking operation，Thereafter if cancellation shaft shoulder rear axle makes two grades into，The dynamic balancing so making rotor assembly performance of beating is better，Strengthen the stability that rotor rotates.
Description
Technical field
This utility model relates to armature spindle technical field, is specially a kind of without the design of shaft shoulder armature spindle.
Background technology
Existing armature spindle is provided with the shaft shoulder mostly, owing to the shaft shoulder makes the versatility of axle reduce, and the rotor being suitable for
The scope of assembly is less, to this end, it is proposed that a kind of without the design of shaft shoulder armature spindle.
Utility model content
The purpose of this utility model is that providing a kind of designs without shaft shoulder armature spindle, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, this utility model provides following technical scheme: one sets without shaft shoulder armature spindle
Meter, including axle, the left end of described axle is socketed with collector ring, is provided with rear solid end pole on the left of the middle part of axle, axle
It is provided with fore paw pole on the right side of Zhong Bu, in the peripheral space of described fore paw pole and rear solid end pole, is provided with bobbin, line
Being wound with field coil in coil, described field coil electrically connects with collector ring.
Preferably, the left side of described rear solid end pole is provided with rear fan blade, and the right side of fore paw pole is provided with front fan blade, institute
State rear fan blade and front fan blade is all connected with axle, the axle on the right side of fore paw pole is socketed with back-up ring, and back-up ring position
In counterbore in the middle part of front fan blade.
Preferably, described axle extends through rear solid end pole and the center of fore paw pole.
Preferably, described axle is equipped with straight burr on the axle of the junction of collector ring, rear solid end pole and fore paw pole
Annular knurl.
Compared with prior art, the beneficial effects of the utility model are: this is cancelled without the design of shaft shoulder armature spindle
The versatility that can make axle after the shaft shoulder is higher, rotor assembly wider being suitable for, can place multiple not
Stack pile or the back-up ring of diameter, and facilitate follow-up rotor metalworking operation, after cancelling the shaft shoulder thereafter
If axle makes two grades into, so make the dynamic balancing of rotor assembly performance of beating better, strengthen rotor and rotate
Stability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 axle, 2 collector rings, fan blade after 3,4 rear solid end poles, 5 bobbins, 6 field coils, 7
Fore paw pole, fan blade before 8.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of without the design of shaft shoulder armature spindle, bag
Including axle 1, the left end of axle 1 is socketed with collector ring 2, is provided with rear solid end pole 4 on the left of the middle part of axle 1, axle 1
Being provided with fore paw pole 7 on the right side of Zhong Bu, axle 1 extends through rear solid end pole 4 and the center of fore paw pole 7, axle 1 and collection
It is equipped with straight knurling, fore paw pole 7 He on the axle 1 of the junction of electricity ring 2, rear solid end pole 4 and fore paw pole 7
It is provided with bobbin 5 in the peripheral space of rear solid end pole 4, bobbin 5 is wound with field coil 6, magnetic field
Coil 6 electrically connects with collector ring 2, and the left side of rear solid end pole 4 is provided with rear fan blade 3, and the right side of fore paw pole 7 sets
There are front fan blade 8, rear fan blade 3 and front fan blade 8 to be all connected with axle 1, the axle 1 on the right side of fore paw pole 7 overlaps
It is connected to back-up ring, and back-up ring is positioned at the counterbore in the middle part of front fan blade 8, can place multiple different-thickness or diameter
The back-up ring of size, and facilitate follow-up rotor metalworking operation, this cancels the shaft shoulder without the design of shaft shoulder armature spindle
The versatility that can make axle afterwards is higher, rotor assembly wider being suitable for.
Embodiment the most of the present utility model, for the ordinary skill people of this area
For Yuan, it is possible to understand that can be real to these in the case of without departing from principle of the present utility model and spirit
Executing example to carry out multiple change, revise, replace and modification, scope of the present utility model is by claims
And equivalent limits.
