Description
【Technical field】
The utility model is related to a kind of fixed structure of permanent-magnet DC electric motor rotor, belongs to permanent-magnet DC electric motor rotor technology
Field.
【Background technology】
In the prior art, permanent-magnet DC electric motor rotor includes rotor core and the shoe permanent magnetism being fixed on rotor core
Body, the reliability fixation of shoe permanent magnet is most important for the normal operation of motor, and its mounting structure is then directly influenced and turned
The efficiency of assembling of son, modal mounting structure position is the outer surface that shoe permanent magnet is arranged on rotor core, and this leads to
Frequently with bonding agent bonding, shoe permanent magnet is adhesively fixed and there is following deficiency：1st, due to motor high speed rotate when shoe forever
Magnet is subjected to very big centrifugal force, and shoe permanent magnet is susceptible to be got rid of de- phenomenon, there is certain potential safety hazard, affects
The normal work of motor；2nd, with the passage of working time, especially operating temperature rise causes glue accelerated ageing, finally causes watt
Shape permanent magnet comes off；3rd, the interference from human factor of artificial gluing is big, affects the stability of batch jobs, and glue became uneven is not only
The cylindrical mistake that rotor core can be made is justified, and affects adhesive strength；4th, glue bonding not only needs firing equipment, and glue is solid
Change needs the time to be dried, and production efficiency is low.
【Utility model content】
The technical problems to be solved in the utility model is to overcome the shortcomings of that above-mentioned prior art exists and provides a kind of knot
Structure is succinct, permanent magnet is easy for installation and the fixed structure of the high permanent-magnet DC electric motor rotor of fixed reliability.
To solve the above problems, the technical solution of the utility model is as follows：
A kind of fixed structure of permanent-magnet DC electric motor rotor, including a rotor core, two pieces of end plates and circumferentially in
A plurality of permanent magnets in convex surface of rotor core outer peripheral face, the inwall of each permanent magnet with the outer peripheral face kissing of rotor core
Close, be fixedly arranged on permanent magnet described in the end plate axially position of rotor core both ends of the surface, its improvement is：The rotor core is from it
Outer peripheral face it is radially projecting go out a plurality of positioning plush coppers being centrosymmetric, the quantity of the permanent magnet and positioning plush copper quantity phase
It is fixed in two neighboring positioning plush copper by means of the detent that its both sides end surface symmetric is arranged Deng, each permanent magnet.
Used as preferential, above-mentioned positioning plush copper is general " t " shape, and the detent positioned at each side end face of permanent magnet has one,
And its shape of detent is adapted with "T"-shaped positioning plush copper.
Above-mentioned positioning plush copper is substantially " I "-shape, and the detent positioned at each side end face of permanent magnet has two, this two positioning
Groove has the shape being adapted with " I " shape positioning plush copper.
Compared with prior art, the beneficial effects of the utility model are as follows：
Rotor core innovative design positioning plush copper, the permanent magnet of convex surface is correspondingly provided with phase therewith in its both sides end face
The detent of matching, then permanent magnet can easily intercalation, assemble simple and effective, circumferentially in the permanent magnetism of rotor core outer peripheral face
Body is then reliably fixed, and the axial restraint of permanent magnet is guaranteed by end plate.When motor rotates at a high speed, permanent magnet is obtained
High reliability is fixed, and permanent magnet will not be got rid of de-, and this design is unique, simple for structure rationally to paste permanent magnet due to being not required to glue,
Overcome poor reliability that bonding agent fixed permanent magnet brought, the drawbacks of installation effectiveness is low.

【Specific embodiment】
In order to be more clearly understood that technology contents of the present utility model, now lift following examples and be described in detail.
Refer to shown in Fig. 1,2,3,4,5, a kind of fixed structure of permanent-magnet DC electric motor rotor, including a rotor core
1st, two pieces of end plates 3 and circumferentially in a plurality of permanent magnets 2 in convex surface of the outer peripheral face of rotor core 1, each permanent magnet 2 it is interior
Wall matches with the outer peripheral face of rotor core 1, is fixedly arranged on permanent magnet described in the axially position of end plate 3 of the both ends of the surface of rotor core 1
2, its improvement is：The rotor core 1 from its outer peripheral face it is radially projecting go out a plurality of positioning plush coppers being centrosymmetric, institute
The quantity for stating permanent magnet 2 is equal with the quantity of positioning plush copper, and each permanent magnet 2 is recessed by means of the positioning that its both sides end surface symmetric is arranged
Groove is fixed in two neighboring positioning plush copper.
Two end plates 3 are fixed on rotor core both ends of the surface by rivet 4, and number of rivets is four.
Used as a kind of embodiment (event easy to understand is not shown), above-mentioned positioning plush copper is general " t " shape, positioned at permanent magnet
The detent of 2 each side end faces has one, and its shape of detent is adapted with "T"-shaped positioning plush copper.
Each "T"-shaped positioning plush copper is shared, i.e., one "T"-shaped positioning plush copper positions the adjacent two pieces of permanent magnets of fixation simultaneously
An adjacent detent.
Used as another embodiment (as shown in Figure 3), above-mentioned positioning plush copper is substantially " I "-shape, positioned at each side of permanent magnet 2
The detent 21 of end face has two, and this two detents 21 have the shape being adapted with " I " shape positioning plush copper 11.
Each " I " shape positioning plush copper 11 is shared, i.e., one " I " shape positioning plush copper 11 positions the adjacent two blocks of permanent magnetism of fixation simultaneously
Adjacent two detents 21 of body.
In this enforcement row：Permanent magnet 2 has six pieces, there is six " I " shape positioning plush coppers 11 on rotor core 1.
When the utility model is specifically installed, in the six pieces of block-by-block of permanent magnet 2 insertings to adjacent " I " shape positioning plush copper 11, make every
Block permanent magnet 2 is close to the outer peripheral face of rotor core 1,
Permanent magnet 2 is all inserted after finishing, and two pieces of end plates 3 are placed to respectively on the end face of rotor core 1, then past to turn
Four through holes (sign) of sub- iron core 1 insert four rivets 4, by two pieces of rivetings of end plate 3, with all of permanent magnet of fixation
2。
Exempt from glue due to the fixation of permanent magnet 2 to paste, also just not there is a problem of that glue needs time solidification dry and painting
The aging problem of glue after covering, and cause the cylindrical problem for losing circle of rotor core 1 due to the glue became uneven for coating.
