Permanent magnet.
Permanent magnet machine rotor has different high requests to rotor pressing ring due to the particularity of its function and structure.At present
Rotor pressing ring be generally made of iron or stainless steel material, do not produce seam during in order to ensure that rotor is laminated between pressing plate and punching
Gap, pressing plate contact surface need to be processed into the inclined-plane with angle, and requirement on machining accuracy is very high.Also, because rotor pressing ring is used
Iron or stainless steel material is made, itself not antimagnetic or easy magnetization, therefore can be mutual when rotor installs permanent magnet
Attract, so as to bump to permanent magnet, cause permanent magnetism bulk damage.
Utility model content
The technical problems to be solved in the utility model is, high to pressing plate requirement on machining accuracy for above-mentioned rotor pressing ring,
And easily there is provided a kind of magneto rotor pressing ring and magneto the problem of bump to permanent magnet.
The technical scheme that the utility model solves above-mentioned technical problem is to provide a kind of magneto rotor pressing ring, wraps
The circular main body being made up of non-magnet material is included, and the inwall of the internal ring portion of the circular main body has axial locating slot；
The radial section of the circular main body is in step-like, and the thickness of outer portion is more than the thickness of internal ring portion；The outer portion
There is the annular groove for being used for placing dynamic balance weight on step surface.
In magneto rotor pressing ring described in the utility model, the width of the outer portion of the circular main body is small
In the width of internal ring portion.
In magneto rotor pressing ring described in the utility model, on the internal ring portion of the circular main body equably
Multiple air vents are provided with, and the plurality of air vent is of the same size.
In magneto rotor pressing ring described in the utility model, the center of circle of the multiple air vent is located at annulus
The center of shape main body is on the circumference in the center of circle.
In magneto rotor pressing ring described in the utility model, the ventilation on the internal ring portion of the circular main body
Hole number is 20.
In magneto rotor pressing ring described in the utility model, the radial section of the annular groove is in inverted trapezoidal,
And the annular groove is provided with the insertion mouth for being used for installing dynamic balance weight.
The utility model also provides a kind of magneto, including stator and rotor, and the rotor is included in any of the above-described
Rotor pressing ring.
Magneto of the present utility model is had the advantages that with rotor pressing ring and magneto：Pass through non-magnetic material
Expect the circular main body that is made and by the step-like structure of circular main body, can not only realize the antimagnetic requirement of motor, and
Product lightweight, convenient operation can be achieved.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model magneto rotor pressing ring embodiment.
Fig. 2 is profile of the magneto rotor pressing ring along line A-A in Fig. 1.
Fig. 3 is profile of the magneto rotor pressing ring along line B-B in Fig. 1.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As Figure 1-3, it is the schematic diagram of the utility model magneto rotor pressing ring embodiment, the rotor pressing ring can
Assembled for rotor punching in magneto.Magneto in the present embodiment is included being made up of non-magnet material with rotor pressing ring
Circular main body (above-mentioned non-magnet material can using aluminum or aluminum alloy etc.), the radial section of the circular main body is in step
Shape (back side with the contact surface of rotor punching), and thickness of the thickness more than internal ring portion 10 of the outer portion 20 of the circular main body
Degree.The inwall of above-mentioned internal ring portion 10 has the locating slot 11 of axial direction, and rotor punching and the rotor pressure are determined when facilitating workman's closed assembly
The relative position of circle；There is the annular groove 21 for being used for placing dynamic balance weight on the step surface of outer portion 20, rotor is conveniently done dynamic flat
Weighing apparatus.
Because above-mentioned circular main body is using non-magnet material and uses step-like structure, antimagnetic requirement can be not only met,
And the lightweight requirements of electronics rotor are met, while the rotor punching that ensures to fit well under frivolous structure is without generation
Gap.
It for the overall weight of further reduction rotor pressing ring, can be less than the width of the outer portion 20 of above-mentioned circular main body
The width of internal ring portion 10.
And in order to meet the radiating requirements (while further mitigating weight) of rotor, the internal ring portion of above-mentioned circular main body
10 can equably set multiple air vents 12 (central shaft of air vent 12 is parallel with the central shaft of circular main body), and the plurality of
Air vent 12 is of the same size.Above-mentioned air vent 12 can facilitate rotor operationally to realize ventilating and cooling, to increase rotor
Service life.
To ensure rotor smooth rotation, positioned at same circumference, (circumference is with annular shape in the center of circle of above-mentioned multiple air vents 12
The center of main body is the center of circle) on.Specifically, to reach preferably ventilation effect, the quantity of the air vent 12 of above-mentioned internal ring portion 10
It can be 20.
The radial section of above-mentioned annular groove 21 can (i.e. the size of the opening of the annular groove 21 be less than inside in inverted trapezoidal
Size) so that in rotor rotation process, dynamic balance weight will not be deviate from from annular groove 21.And for ease of by dynamic balance weight
Annular groove 21 is assembled to, can be provided for installing the insertion mouth 22 of dynamic balance weight on annular groove 21.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should
It is defined by scope of the claims.
