Abstract

The utility model discloses a motor. The motor comprises an armature and a stator. Left and right ends of the armature are provided with a rear end cap and a front end cap respectively. A sealing ring is sleeved and connected between the front end cap and the right end of the armature. A brush assembly is arranged between the rear end cap and the left end of the armature. The brush assembly comprises a carbon brush, a brush sleeve and a brush holder. The brush sleeve is fixed on the brush holder through a rivet. A flat spiral spring and the carbon brush are arranged on the brush sleeve. The carbon brush is in an arc shape. According to the utility model, the sealing ring is sleeved and connected between the front end cap and the right end of the armature; the sealing ring can be used to prevent impurities from entering into the motor so that the service life of the motor is prolonged. The flat spiral spring and the carbon brush are arranged on the brush sleeve, the flat spiral spring is used to replace an elastic metal sheet in an original brush assembly so that an elastic force direction of the flat spiral spring in the brush assembly to a commutator is inward, which means to clamp the direction of the commutator. A contact capability between the brush and the commutator is increased. The motor possesses the characteristics that stability is high and an anti-vibration coefficient is high.

Description

A kind of motor

Technical field

The utility model relates to a kind of motor, belongs to machine field.

Background technology

Motor stabilizing of the prior art is poor, especially in brushgear, often breaks down.The effect of brush is that electric current is introduced to armature winding, and brush of the prior art is general, adopt a pair of elastic sheet metal to form, one end of brush is contacted with commutator, brush is motionless, armature rotates under the effect of electromagnetic force, in existing motor mounting technology, after general first rectification sub-member assembles, again brush is in place, contact with conducting strip fixing on commutator, for coordinating the miniature design of vibrating motor to need, the structure of brush is also more and more less, between two elastic sheet metals, it is commutator, elastic sheet metal steps up commutator towards interior under the effect of elastic force, and commutator produces reaction force to elastic sheet metal, make original brush elastic force direction outside, leave commutator direction, finally there is motor failure.

Utility model content

The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide that a kind of stability is high, anti-vibration coefficient is high, the motor of long service life.

For achieving the above object, the technical solution of the utility model is: a kind of motor, comprise armature and stator, the left and right two ends of described armature are respectively equipped with rear end cap and front end housing, between described front end housing and the right-hand member of armature, be socketed with sealing ring, between described rear end cap and the left end of armature, be provided with brush assembly of electric, described brush assembly of electric comprises carbon brush, brush cover and brush holder, described brush cover is fixed on brush holder by rivet, and described brush puts and is provided with plane scroll spring and carbon brush.

Further setting as such scheme: described carbon brush is arc.

The beneficial effects of the utility model are: between front end housing of the present utility model and the right-hand member of armature, be socketed with sealing ring, sealing circle can prevent that impurity from entering in motor, increased the useful life of motor; Brush puts and is provided with plane scroll spring and carbon brush, with plane scroll spring, substitute the elastic sheet metal in original brush assembly of electric, making the plane scroll spring in brush assembly of electric is inside to the elastic force direction of commutator, clamp commutator direction, strengthened the engagement capacity between brush and commutator, it is high that this motor has stability, the feature that anti-vibration coefficient is high.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of brush assembly of electric of the present utility model;

Fig. 3 is the vertical view of Fig. 2.

Wherein: brush assembly of electric 1, carbon brush 11, brush cover 12, plane scroll spring 13, brush holder 14, rivet 15, rear end cap 2, front end housing 3, stator 4, armature 5, sealing ring 6.

Embodiment

Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of motor of the utility model, comprise armature 5 and stator 4, the described left and right two ends of armature 5 are respectively equipped with rear end cap 2 and front end housing 3, between described front end housing 3 and the right-hand member of armature 5, be socketed with sealing ring 6, between described rear end cap 2 and the left end of armature 5, be provided with brush assembly of electric 1, described brush assembly of electric 1 comprises carbon brush 11, brush cover 12 and brush holder 14, described brush cover 12 is fixed on brush holder 14 by rivet 15, and described brush cover 12 is provided with plane scroll spring 13 and carbon brush 11.Described carbon brush 11 is arc.

Between front end housing 3 of the present utility model and the right-hand member of armature 5, be socketed with sealing ring 6, sealing circle 6 can prevent that impurity from entering in motor, increases the useful life of motor; On brush cover 12, be provided with plane scroll spring 13 and carbon brush 11, the elastic sheet metal substituting in original brush assembly of electric with plane scroll spring 13, the elastic force direction that makes 13 pairs of commutators of plane scroll spring is inside, clamp commutator direction, strengthened the engagement capacity between brush and commutator, it is high that this motor has stability, the feature that anti-vibration coefficient is high.
