Description
Technical field
The utility model relates to a kind of motors, and in particular to a kind of motor sliding ring carbon brush holder.
Background technique
The effect of carbon brush frame for motor is that pressure is added in the carbon slidably contacted the surfaces with commutator or collector ring by spring
It paints, it is made steadily to conduct electric current between fixed body and rotary body.For motor, carbon brush holder and carbon brush are all very heavy
The component wanted, but whether the characteristic of brush how well, if brush holder is improper, brush cannot not only give full play to the excellent of it
Good characteristic, and very big influence can be brought to the performance of motor itself and service life.The structure of carbon brush holder is to maintain carbon brush and is advising
The brush box part set is positioned, the pressurized part that carbon brush vibrates to prevent blocking brush is pushed down with appropriate pressure, connects brush box and pressurization
Partial frame part and the fixed part composition being fixed to brush carrier on motor.For the carbon brush of some large-scale generators
Frame mostly uses one group of slip ring to correspond to the structure of multiple carbon brush, and in the same side, conducting ring is disposed in intermediate right for positive and negative slip ring setting
Claim position, but the carbon brush holder of this structure arrangement is excessively compact, carbon brush axial dimension is small, it is difficult to repair, and when a carbon brush
It blows and carbon brush holder other component is be easy to cause to burn out, or even lead to major accident.
Summary of the invention
To solve problems of the prior art, the utility model provides a kind of motor sliding ring carbon brush holder, facilitates maintenance
It checks equipment, carbon brush can also be replaced in operation, guarantee production safety.
Used technical solution to achieve the goals above: a kind of motor sliding ring carbon brush holder, including carbon brush holder, conduction
Ring, carbon brush bar and slip ring, the inside of carbon brush holder two sides end plate is respectively set in the conducting ring, between conducting ring and carbon brush holder end plate
Equipped with insulation board；Carbon brush bar is connected through a screw thread respectively on the conducting ring of two sides, and each carbon brush bar is set with several brush clamps, brush
The side of folder is fixedly connected with brush carrier, and for brush frame sliding sleeve on brush carrier, the upper end of brush clamp is connected with soft copper pigtail, soft copper pigtail it is another
One end is connected on brush frame, and carbon brush block is mounted in brush frame, is connected with compressed spring on carbon brush block.
The outside of slip ring is arranged in conducting ring, while carbon brush bar is arranged in centre, makes between the axial direction between carbon brush in this way
Away from increase, failure rate is reduced, while being mounted on the excitation cable below conducting ring and being also arranged at two sides, it is easier to maintenance and more
It changes；Carbon brush is pressed on slip ring by compressed spring, to realize that conducting ring is stable by brush holder support, brush clamp, carbon brush block by electric current
It is transferred on slip ring.
In order to make brush carrier be unlikely to generate heat because electric current flows through, insulating trip is equipped between the brush clamp and brush carrier.Cutting electricity
Logical circulation road makes whole electric currents enter carbon brush block into soft copper pigtail is crossed, just in case to blow the then brush block out of service for soft copper pigtail, be unlikely to because
Electric current flows through brush carrier into brush clamp excessively and causes failure.
Further, the top of the carbon brush block is wedge structure, and compressed spring is pressed on the inclined-plane for writing wedge structure.
The brush clamp is arranged in the identical side in slip ring direction of rotation.
Due to having certain frictional force to carbon brush block bottom when slip ring rotation, compressed spring is oblique for carbon brush block upper end
Face has a horizontal component, and two power constitute the torque that carbon brush block twists in brush carrier in order to prevent, makes carbon brush block and slip ring phase
Bite is caused when to sliding, causes poor contact, therefore brush clamp is arranged in the identical side in slip ring direction of rotation.
For more preferable ventilating and cooling, negative effect caused by the fever of carbon brush position is prevented, is equipped between two carbon brush bars cold
But fan.
In order to further improve the effect that is bonded of carbon brush bar, threaded connection place between the carbon brush bar and conducting ring
Equipped with fastening nut.
In the applicable large-scale generator of the utility model, failure rate is not only reduced, while more convenient maintenance overhaul is set
It is standby, carbon brush can also be replaced in operation, guarantee production safety.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of motor sliding ring carbon brush holder, including carbon brush holder 1, conducting ring 2, carbon brush bar 3 and slip ring
10, the inside of 1 two sides end plate of carbon brush holder is respectively set in the conducting ring 2, is equipped with insulation between 1 end plate of conducting ring 2 and carbon brush holder
Plate 4；Carbon brush bar 3 is connected through a screw thread respectively on the conducting ring 2 of two sides, and each carbon brush bar 3 is set with several brush clamps 5, brush clamp 5
Side be fixedly connected with brush carrier 6, for 7 sliding sleeve of brush frame on brush carrier 6, the upper end of brush clamp 5 is connected with soft copper pigtail 14, soft copper pigtail
14 other end is connected on brush frame 7, and carbon brush block 13 is mounted in brush frame, and compressed spring 8 is connected on carbon brush block 13,
The outside of slip ring 10 is arranged in conducting ring 2, while carbon brush bar 3 is arranged in centre, makes the axis between carbon brush in this way
Increase to spacing, failure rate reduces, while the excitation cable for being mounted on 2 lower section of conducting ring is also arranged at two sides, it is easier to tie up
It repairs and replaces；Carbon brush block 13 is pressed on slip ring 10 by compressed spring 8, thus realize conducting ring 2 by electric current by carbon brush bar 3,
Brush clamp 5, carbon brush block 13 are stable to be transferred on slip ring 10.
In order to make brush carrier 6 be unlikely to generate heat because electric current flows through, insulating trip 9 is equipped between the brush clamp 5 and brush carrier 6.It cuts
Logical circulation road is powered off, whole electric currents is made to enter carbon brush block 13 into soft copper pigtail 14 is crossed, just in case soft copper pigtail 14 is blown, which exits fortune
It is capable, it is unlikely to failure caused by flowing through brush carrier 6 into brush clamp 5 excessively because of electric current.
Further, the top of the carbon brush block 13 is wedge structure, and compressed spring 8 is pressed in the inclined-plane for writing wedge structure
On.
The brush clamp 5 is arranged in the identical side in 10 direction of rotation of slip ring.
There is certain frictional force to 13 bottom of carbon brush block when rotating due to slip ring 10, compressed spring 8 is for carbon brush block 13
The inclined-plane of upper end has a horizontal component, and two power constitute the torque that carbon brush block 13 twists in brush carrier 6 in order to prevent, makes carbon brush
Block 13 and slip ring 10 cause bite when sliding relatively, cause poor contact, therefore brush clamp 5 is arranged in 10 direction of rotation of slip ring
Identical side.
For more preferable ventilating and cooling, negative effect caused by the fever of carbon brush position is prevented, is equipped between two carbon brush bars 3 cold
But fan 11.
In order to further improve the effect that is bonded of carbon brush bar, it is threadedly coupled between the carbon brush bar 3 and conducting ring 2
Place is equipped with fastening nut 12.
