Description
Technical field
The invention belongs to magneto technical fields, and in particular to a kind of built-in permanent magnetic rotor pressing ring.
Background technique
In recent years, with the proposition of national " energy-saving and emission-reduction " slogan, the application range of large and medium-sized built-in permanent magnetic motor is got over
Come wider, but often tooth pine phenomenon is occurred after built-in permanent magnetic electric machine rotor iron core press fitting at present, tooth pine after rotor core press fitting
It can cause electromagnetic noise, affect the service performance of motor.
Summary of the invention
The present invention is often the technical issues of tooth pine phenomenon occurred after solving the press fitting of built-in permanent magnetic electric machine rotor iron core, is mentioned
A kind of built-in permanent magnetic rotor pressing ring is supplied.
The technical solution adopted by the invention is as follows:
A kind of built-in permanent magnetic rotor pressing ring, including rotor pressing ring ontology, the outer edge of rotor pressing ring ontology is along it
Even circumferential is equipped at intervals with several poles, and each magnet steel that is extremely equipped with installs square hole, and each magnet steel installation square hole has for pacifying
The face that conjunction bolt hole, rotor pressing ring ontology and rotor punching are fitted for filling magnetic pressure plate is equipped with press fitting step.
The height of the press fitting step is 1~3mm.
Each magnet steel installation square hole has one or more conjunction bolt hole.
Ventilation slot is equipped between the two neighboring pole of rotor pressing ring ontology.
The ventilation slot is " V " shape structure.
Beneficial effects of the present invention: the configuration of the present invention is simple, high reliablity, it is easily manufactured, can effectively improve it is embedded forever
Magneto fills magnetic efficiency, by the setting press fitting step on the face that rotor pressing ring ontology and rotor punching fit, can eliminate and turn
The phenomenon of tooth pine after sub- iron core pressure mounting, further increases the performance of magneto, and the present invention passes through the phase on rotor pressing ring ontology
" V " shape ventilation slot is set between two adjacent poles, the ventilation of interpolar can be effectively improved.
Detailed description of the invention
Fig. 1 is main view of the invention；
Fig. 2 is side view of the invention.
In figure: 1- rotor pressing ring ontology, the pole 2-, 3- magnet steel install square hole, and for 4- conjunction bolt hole, 5- is pressed step, and 6- is logical
Wind groove, 7- magnet steel, 8- magnetic pressure plate.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, a kind of built-in permanent magnetic rotor pressing ring, including rotor pressing ring ontology 1, rotor pressing ring ontology
1 outer edge is equipped at intervals with several poles 2 along its even circumferential, and each pole 2, which is equipped with, installs square hole for the magnet steel of mounting magnetic steel 7
3, need the quantity of mounting magnetic steel 7 to match in the quantity and rotor core of magnet steel installation square hole 3, each magnet steel installs square hole 3
Have for install magnetic pressure plate 8 conjunction bolt hole 4, the quantity conjunction bolt hole 4 is set as one or more, in order to disappear
Except the tooth pine phenomenon after rotor core press fitting, the rotor pressing ring ontology 1 is equipped with pressing platform with the face that rotor punching fits
The height of rank 5, the press fitting step 5 is set as 1~3mm.
For the ventilation being effectively improved between pole 2, " V " shape ventilation slot 6 is equipped between the two neighboring pole 2 of rotor pressing ring ontology 1.
The configuration of the present invention is simple, high reliablity, it is easily manufactured, built-in permanent magnetic motor dress magnetic efficiency can be effectively improved, is led to
The setting press fitting step 5 on the face that rotor pressing ring ontology 1 and rotor punching fit is crossed, tooth pine after rotor core press fitting can be eliminated
The phenomenon that, the performance of magneto is further increased, the present invention passes through between adjacent two poles 2 on rotor pressing ring ontology 1
" V " shape ventilation slot 6, the ventilation that can be effectively improved between pole 2 are set.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
