Description

Novel carbon brush box fixing structure

Technical Field

The utility model relates to the technical field of carbon brush motors, in particular to a novel carbon brush box fixing structure.

Background

The carbon brush is used as a sliding contact body for conducting current, the rotor current required by the operation of the motor is led into a rotor coil through a connecting sheet on a sliding ring, the matching degree and the jumping size of the carbon brush and the connecting sheet affect the service life and the reliability of the carbon brush, and the stability of the carbon brush assembly is particularly important. In the shell type brush motor, two carbon brushes are symmetrically fixed at two ends of a shell through screws in a structure of a carbon brush assembly and are contacted with a commutator, the carbon brushes in the carbon brush assembly are assembled in a carbon brush box, the carbon brush box is limited through a boss and is pressed into a carbon brush seat, then a warped piece on the carbon brush box is pulled up, and the carbon brush box is limited and fixed again;

the fin on the carbon brush box carries out the perk from openly usually, the fin angle is difficult to control in the course of working, spacing degree of accuracy is not high, the motor produces vibration during operation, the horizontal effort relative motion that produces of carbon brush box and carbon brush seat and mutual extrusion, the fin holding power is not enough, fin perk angle diminishes, the carbon brush box takes place the displacement to the commutator end, then the carbon brush spring is to the carbon brush, the pressure grow of commutator, the power inequality that produces the commutator as the both ends carbon brush, the motor easily produces the spark, and the wearing and tearing aggravation of carbon brush, influence the motor life-span.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to a novel carbon brush box fixing structure to solve the above-mentioned problems of the prior art.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a new carbon brush box fixed knot constructs, includes the carbon brush seat, be equipped with the carbon brush box in the carbon brush seat, be equipped with the carbon brush spring in the carbon brush box, carbon brush box one end is equipped with the carbon brush, the carbon brush is close to the one end of carbon brush box is equipped with the brush whip, the carbon brush box is kept away from the other end of carbon brush is equipped with the copper sheet, carbon brush box upper end is equipped with the boss, the carbon brush box is close to one of copper sheet is served and is equipped with the fin.

Preferably, the brush whip penetrates through the carbon brush box, and one end of the brush whip is fixedly connected with the copper sheet in a spot welding manner.

Preferably, the boss, the fin and the carbon brush box are of an integrally formed structure, and the boss is tangent to one side of the carbon brush seat far away from the fin.

Preferably, the carbon brush holder is close to one end of fin be equipped with fin assorted U type groove, just fin one side edge with the U type groove is contradicted and is connected.

Preferably, the bending line of the fin is consistent with the length direction of the carbon brush box.

Preferably, two ends of the carbon brush spring are further provided with limiting blocks fixedly connected with the carbon brush box.

Advantageous effects

According to the novel carbon brush box fixing structure, the warping sheet is tilted from the side surface, the transverse supporting force of the warping sheet is increased, the influence of the bending angle of the warping sheet on the fixation of the carbon brush box is reduced, the stability of the carbon brush assembly structure is enhanced, the abrasion of the carbon brush is reduced, and the service life of the motor is prolonged.

Reference numerals

1-carbon brush, 2-carbon brush box, 3-carbon brush spring, 4-carbon brush seat, 5-copper sheet, 6-boss, 7-fin, 8-brush whip, and 9-limiting block.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1-2, a new carbon brush box fixing structure includes a carbon brush base 4, a carbon brush box 2 is disposed in the carbon brush base 4, a carbon brush spring 3 is disposed in the carbon brush box 2, a carbon brush 1 is disposed at one end of the carbon brush box 2, a brush whip 8 is disposed at one end of the carbon brush 1 close to the carbon brush box 2, a copper sheet 5 is disposed at the other end of the carbon brush box 2 far from the carbon brush 1, a boss 6 is disposed at an upper end of the carbon brush box 2, and a fin 7 is disposed at one end of the carbon brush box 2 close to the copper sheet 5.

Preferably, the brush whip 8 penetrates through the carbon brush box 2, and one end of the brush whip 8 is fixedly connected with the copper sheet 5 in a spot welding manner.

Preferably, boss 6, fin 7 and carbon brush box 2 are the integrated into one piece structure, and boss 6 is tangent with one side that carbon brush seat 4 kept away from fin 7.

Preferably, one end of the carbon brush holder 4 close to the fin 7 is provided with a U-shaped groove matched with the fin 7, and one side edge of the fin 7 is connected with the U-shaped groove in an abutting mode.
