Abstract
A motor brush box unit comprises a brush box, an elastic part and an electric brush, wherein the elastic part is erected at the front end of the brush box and the electric brush is sleeved in the brush box and pressed by the elastic part. The brush box is a hollow tube, an electric brush cavity communicating the front portion of the hollow tube with the rear portion of the hollow tube is arranged in the hollow tube, and support parts are symmetrically distributed on the left side and the right side of the front end of the brush box. The elastic part is a thin steel strip which is formed by bending, two ends of the thin steel strip are provided with coil spring structures respectively, and the middle of the elastic part is pressed at the rear end of the electric brush. The motor box brush unit has the advantages that the motor brush box is simple in structure and the electric brush is long in service life.
Description
Technical field
The utility model relates to a kind of brush accessory.
Background technology
Science and technology is in development, and motor is in development, and in motor power supply field, the development of brush also needs the support of brush accessory accordingly.The brush unit of prior art; Elastic force output to brush is inhomogeneous, and need on the brush brush holder, hanging column be set with fixing spring, is announced this type of brush unit like the patent No. by 03813657.0 invention; This type spring makes the monolateral stressed brush uneven wear that causes of brush easily; Reduce the life-span of brush, and increased brush brush holder technology, increased cost.
Summary of the invention
Have brush life weak point in the brush unit now in order to overcome, the deficiency that the technology cost is high, the utility model provides a kind of brush life long, motor brush box unit simple in structure.
The technical scheme that the utility model solves its technical problem is: a kind of motor brush box unit, be set up in the elastic component of brush box front end, and be sheathed in the brush box and receive the brush of elastic component compressing; Said brush box is a hollow pipe, in the brush chamber that connects before and after being provided with, said brush box front end left and right sides is installed with the supporter of symmetrical distribution; Described elastic component is the thin steel bar that the two ends of brake forming have the wind spring structure, and elastic component middle part compressing brush rear end.Said supporter has supporting surface forward, can prop up the wind spring structure on the elastic component.
Further, described supporter and brush box are integral structures.Said supporter is that a part of bending on the brush box forms, with the manufacturing cost that reduces.
Further, described brush chamber left and right sides also is provided with the wind spring chamber of fore-and-aft direction.The elongated portion that forms when wind spring extends is fitted in the brush left and right sides, the wind spring chamber is set so that brush is movable.
Further, described brush box top is provided with the metallic channel of fore-and-aft direction, and the lead of said brush is arranged on the brush upper side, and the brush unit that is provided with like this can adapt to the more motor of small size, and has shortened the last length of brush upper conductor, can save cost.
The utility model is against the wind spring structure at two ends on the elastic component on the supporter of brush box left and right sides in use, and the middle part that then brush is propped up wind spring is pressed into the brush chamber backward, and the wind spring structure then is out of shape diastole, to brush elastic force radially is provided.And the wind spring structure at two ends again because pressure is backward arranged, is fixed on this position also because of the existence at centre brush and supporter firmly, needn't use hanging column.
The beneficial effect of the utility model is: brush life is long, and is simple in structure.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
In conjunction with accompanying drawing 1,2,3, a kind of motor brush box unit comprises brush box 1, elastic component 2, brush 3; Said brush box is a hollow pipe, in the brush chamber 4 that connects before and after being provided with, brush chamber left and right sides is provided with wind spring chamber 7, some the outside bending of said brush box front end left and right sides forms supporter 5; Described elastic component is the thin steel bar that the two ends of brake forming have wind spring structure 6; Described brush box top is provided with the metallic channel 8 of fore-and-aft direction, and the lead 9 of said brush is arranged on the brush upper side.
The utility model is against the wind spring structure at two ends on the elastic component on the brush box left and right sides supporter in use, and the middle part that then brush is propped up wind spring is pressed into the brush chamber backward, and the wind spring structure then is out of shape diastole, to brush elastic force is provided.And the wind spring structure at two ends is also because the existence of centre brush and supporter again because the pressure that behind the motor of packing into, has slip ring to provide is fixed on this position firmly, needn't be used hanging column.
The elongated portion of wind spring structure then is fitted in the both sides of brush, when brush gets into the brush chamber, also puts under in the wind spring chamber of special setting, can not have influence on brush and slide.
The lead on brush top is because the existence of upper guide wire casing has influence on the brush slip and can not hindered by brush box.
Because the elastic component of present embodiment is the wind spring structure of two ends symmetry elastic force is provided, so elastic force is uniformly, brush is stressed evenly, and useful life is just long.
In conjunction with accompanying drawing 4,5,6, a kind of motor brush box unit comprises brush box 1, is set up in the elastic component 2 of brush box front end, is sheathed in the brush box and the brush 3 that oppressed by elastic component; Said brush box is a hollow pipe, in the brush chamber 4 that connects before and after being provided with, said brush box front end left and right sides is installed with symmetrically arranged supporter 5; Described elastic component is the thin steel bar that the two ends of brake forming have wind spring structure 6.
The utility model is against the wind spring structure at two ends on the elastic component on the brush box left and right sides supporter in use, and the middle part that then brush is propped up wind spring is pressed into the brush chamber backward, and the wind spring structure then is out of shape diastole, to brush elastic force is provided.And the wind spring structure at two ends again because the pressure that behind the motor of packing into, has slip ring to provide is fixed on this position firmly, needn't be used hanging column also because of the existence at centre brush and supporter.
Because the elastic component of present embodiment is the wind spring structure of two ends symmetry elastic force is provided, so elastic force is uniformly, brush is stressed evenly, and useful life is just long.
