Abstract
The invention relates to a motor rotor which comprises a rotor shaft and a magnet, wherein the magnet is sleeved outside the rotor shaft, the rotor shaft and the magnet are poured into a whole through plastics, rubber or other high-specific gravity materials, and the plastics, the rubber and the other high-specific gravity materials annularly extend towards two ends of the rotor shaft. The method for machining the motor rotor comprises the steps of: manufacturing the rotor shaft; fixing and forming magnet on the peripheral surface of the rotor shaft, injecting the plastics, the rubber and the other high-specific gravity materials between the magnet and the rotor shaft, enabling the plastics, the rubber and the other high-specific gravity materials to annularly extend towards the two ends of the rotor shaft; and removing partial plastics, rubber and other high-specific gravity materials on annularly extending positions at the two ends of the rotor shaft, so as to keep balance of the motor rotor. By adopting a balance reducing method, the motor and method provided by the invention eliminate the hidden danger that a balance material drops due to high-rotating shaft rotation of the rotor or high temperature, are convenient for operation, and have a simple structure.
Description
Technical field
the present invention relates to machine field, the method that particularly relates to a kind of rotor and process this rotor.
Background technology
rotor is the important composition parts that constitute motor; The characteristic of rotor has directly influenced the stability of machine operation; Just include rotor balancing property and influence in the factor of rotor characteristics; The imbalance of rotor is because the damaged fault that causes appears in rotor part mass eccentricity or rotor part, and traditional also is present the most widely used balance method that is to say on rotor, to add balance clay or other material on rotor, to add balance; And make its curing through high temperature, to reach rotor balancing.The shortcoming below but this method that adds balance exists:
(1), the time of processing or adjustment is long, technological operation is loaded down with trivial details;
(2), need hot setting, and can produce irritative gas;
(3), exist because of the high rotational speed of rotor or high temperature cause and add the hidden danger that the balance material comes off, cause electrical machinery life to shorten even damage.
Summary of the invention
an object of the present invention is to provide a kind of rotor.
For achieving the above object, the technical scheme that the present invention adopts is:
a kind of rotor; It is characterized in that: comprise armature spindle, be set in the outside magnetite of described armature spindle; Pour into an integrated entity through plastics, rubber or other high specific gravity materials between described armature spindle and the magnetite, and described plastics, rubber or other high specific gravity materials extend towards the two ends annular of described armature spindle.
For achieving the above object, the technical scheme that the present invention adopts is:
A kind of method of processing rotor may further comprise the steps:
(1), makes armature spindle;
(2), on the outer peripheral face of armature spindle fixing shaping magnetite, injected plastic, rubber or other high specific gravity materials between magnetite and armature spindle, and plastics, rubber or other high specific gravity materials are extended towards the two ends annular of armature spindle;
Partly plastic, rubber or other high specific gravity materials of
(3), removal armature spindle two ends annular extended position, the balance of maintenance rotor.
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
The rotor that
the present invention is integrally formed armature spindle and magnetite through plastics, rubber or other high specific gravity materials also extends with annular; And when carrying out balance adjustment, adopt the material of removing the part of two ends annular extended position on the rotor, promptly adopt to subtract balance method to realize the purpose of rotor balancing; Like this; Overcome high rotational speed of rotor or high temperature and caused and added the hidden danger that the balance material comes off, easy to operate, simple in structure.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
accompanying drawing 2 is the application drawing of the present invention in motor.
wherein: 1, armature spindle; 2, magnetite; 3, plastics, rubber or other high specific gravity materials; 4, stator; 5, rotor; 6, casing.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:

(1), makes armature spindle 1;
(2), on the outer peripheral face of armature spindle 1, fix shaping magnetite 2; Injected plastic, rubber or other high specific gravity materials 3 between magnetite 2 and armature spindle 1, and plastics, rubber or other high specific gravity materials 3 of two ends of rotor are extended towards the two ends annular of armature spindle 1;
(3), remove plastics, rubber or other high specific gravity materials 3 of the removal two ends of rotor annular extending part be infused between armature spindle 1 and the magnetite 2, with the balance of realization rotor;
a kind of motor as shown in Figure 2 comprises the rotor 5 that stator 4 is inner with being installed on stator 4, and motor also comprises can housing stator 4 and the shell 6 of rotor 5.
The rotor of
the present invention through being integrally formed such as plastics, rubber or other high specific gravity materials and axle and magnetite; And when carrying out balance adjustment; Adopt the materials such as partly plastic of removing annular extended position in two ends on the rotor, promptly adopt to subtract balance method to realize the purpose of rotor balancing; And traditional rotor balancing method to be the suitable position that is employed in rotor add such as balance clay or other material to reach the balance purpose; This method is called and adds balance method; But exist because of the high rotational speed of rotor or high temperature cause and add the hidden danger that the balance material comes off, cause electrical machinery life to shorten even damage.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
