Description
Technical field
This utility model relates to reducing motor technical field, particularly relates to the brush box of a kind of direct current generator.
Background technology
Existing direct current generator is generally divided into brush direct current motor and DC brushless motor.Pass through inside DC brushless motor
Hall element sensor feeds back to control circuit the position of motor rotor and is controlled so that it is can know that motor phase is changed
To correct time, there is neat and tidy, the advantage that noise is little, but structure is complex, production cost is high.DC brush electricity
Machine controls the correct time of commutation, simple in construction by brush-diverter that inside configures, and production cost is relatively low, and
It is easy to maintenance maintenance.
Brush-diverter is the core component of brush direct current motor, and it is straight whether the work between them stablizes direct relation
The work accuracy of stream brush motor.Diverter is the most fixedly sleeved in the rotating shaft of motor, and brush is fixed on by brush box
On the casing of motor housing so that brush can be with diverter para-position, it is ensured that stablizing of commutating period and reversal interval.Existing electricity
Brush box is loosely organized, after being connected with motor housing, is difficult to disassembling, assembling and replacing maintenance, and brush the most easily rocks, and whole direct current has
The noise of brush motor work is the biggest.
Utility model content
The technical problems to be solved in the utility model is: provide the brush box of a kind of direct current generator, and this brush box structure is tight
Gather, easy accessibility after being connected with motor housing, it is simple to maintenance is changed, and it is stable to can guarantee that brush standing back is put, and is difficult to rock.
In order to solve described technical problem, the technical solution of the utility model: the brush box of a kind of direct current generator, it is arranged on
On the motor housing of direct current generator, being used for installing direct current brush, described brush box includes base, an end face epirelief of described base
Rising and be formed with a boss, be provided with installing hole in described boss, described base is provided with installing port relative to the other end of boss, institute
State installing hole to run through boss and connect with base and with described installing port, in described installing port, be provided with First terrace and second step
Face, the opening surface of described installing hole is arranged on First terrace, is provided with a spliced eye, described installation on second step face
The inwall of mouth is provided with buckle.
As preferably, described connection sheet is equipped with screwed hole at the medium position of base.
As preferably, being additionally provided with one and install spacer on base, described installation spacer is curved to boss direction
Bending, described installation spacer and two connection T-shaped settings of sheet.
As preferably, described spliced eye is arranged on the side of the remotely mounted spacer in second step face.
Compared with prior art, this utility model uses such scheme to have advantage: 1, by floor installation electricity
Brush, brush good fixing effect, it is difficult to rock so that the commutating period of whole DC brush motor is difficult to deviation occur；On base
It is provided with installation spacer, it is simple on floor installation to motor housing；Connection sheet and motor housing is used to be attached fixing, connected mode
Employing is spirally connected, simple in construction, low cost of manufacture, and is prone to disassembling, assembling and replacing maintenance.

Detailed description of the invention
Below by combining the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Seeing in figure, this utility model provides the brush box 3 of a kind of brush direct current motor, is used for installing brush 5, makes brush
5 can be good at positioning with diverter, it is ensured that everything goes well with your work for whole brush direct current motor normally.This brush box 3 includes
One base, on an end face of base, projection is formed with a boss 31, and boss 31 is in rectangular-shaped, and the inside of boss 31 sets
There is installing hole 39.Base another end face on be provided with installing port, the installing hole 39 on boss 31 runs through boss 31 and the end
Seat communicates with installing port, i.e. an opening surface of installing hole 39 is arranged on installing port.When brush 5 is installed, brush 5 is arranged on
In installing hole 39, the brush of brush 5 is arranged on the end of boss 31, and the brush tail of the brush 5 i.e. installation portion of brush 5 is arranged on installation
At Kou.Installing port is provided with two step surfaces, respectively First terrace 35 and second step face 36, the opening surface of installing hole 39
Being arranged on First terrace 35, when brush 5 is installed, the brush tail end of brush 5 is concordant with First terrace 35.
The both sides of base are extended with two and connect sheet 33, connect sheet 33 and bend to boss 31 direction, and curved shape connects sheet
33 are provided with screwed hole 38 at the medium position of boss 31, when installing brush box 3, connect sheet 33 and are close to the outer container of motor housing
Wall, will connect sheet 33 by screw 6 and motor housing tank wall will connect fixing.Base is additionally provided with one spacer 32, peace are installed
Set bit slice 32 also to bend to boss 31 direction, curved setting.Specifically, spacer 32 protrusion is installed and is formed at the upper of base
Vertical along being connected sheet 33 with two, overall T-shaped shape is arranged, and installs spacer 32 and makes brush box be easier to location and installation.
