Abstract

The utility model relates to an electric motor rotor which comprises a rotor shaft and a magnet which is sleeved on an external part of the rotor shaft. The rotor shaft and the magnet are cast into a whole body through plastic, rubber or other heavy weight material. The plastic, rubber or other heavy weight material is in annular extension towards two ends of the rotor shaft. According to the utility model, a purpose of rotor balance is realized through employing a reducing balance method, a hidden danger of falling of an adding balance material caused by high speed rotation of the rotor or high temperature is overcome, operation is convenient, and a structure is simple.

Description

A kind of rotor
Technical field
the utility model relates to machine field, particularly relates to a kind of 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
The purpose of the utility model provides a kind of rotor.
For achieving the above object, the technical scheme that the utility model 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.
Because the technique scheme utilization, the utility model compared with prior art has advantage and effect:
The rotor that the utility model 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 the structural representation of the utility model;
accompanying drawing 2 is the application drawing of the utility model 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 utility model is further described:
a kind of rotor as shown in Figure 1; Comprise armature spindle 1, be set in the outside magnetite 2 of armature spindle 1; Pour into an integrated entity through plastics, rubber or other high specific gravity materials 3 between armature spindle 1 and the magnetite 2, and plastics, rubber or other high specific gravity materials 3 extend towards the two ends annular of armature spindle 1.Its concrete manufacture method is following:
(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 utility model 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 is only for explaining the technical conceive and the characteristics of the utility model; Its purpose is to let the personage who is familiar with this technology can understand content of the utility model and enforcement according to this, can not limit the protection range of the utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the utility model.

Claims (1)

1. rotor; It is characterized in that: comprise armature spindle (1), be set in the outside magnetite (2) of described armature spindle (1); Pour into an integrated entity through plastics, rubber or other high specific gravity materials (3) between described armature spindle (1) and the magnetite (2), and described plastics, rubber or other high specific gravity materials (3) extend towards the two ends annular of described armature spindle (1).
