Abstract
The utility model discloses a carbon brush, including a carbon brush body and sheetmetal, a carbon brush body is trapezoidal piece, and the up end of a carbon brush body is equipped with the arc wall, and preceding terminal surface is equipped with the V -arrangement groove, is connected with spring and wire between a carbon brush body tail end and the sheetmetal, and the wire passes the spring. The utility model discloses simple structure, convenient to use has reduced a carbon brush and the friction that other equipment produced effectively in operation process, prolong its life. Simultaneously, a carbon brush and wire, wire and the equal firm in connection of sheetmetal are difficult for droing, and be durable, has prolonged its life.
Description
Technical field
This utility model relates to technical field of motors, is specifically related to a kind of carbon brush.
Background technology
Carbon brush, as a kind of slide contact member, is widely used in many electrical equipments, mainly uses
Energy or letter is transmitted between motor or electromotor or the standing part of other rotating machinery and rotating part
Number.It is usually pure carbon and adds coagulator and make, and external form mostly is square, and front end is a cambered surface.Such
Structure is in use worn and torn greatly, and service life is short, needs periodic maintenance to change, and clears up carbon distribution, behaviour
Bother.
The carbon brush of prior art and wire, wire and sheet metal are all directly fixing connections, usually can be because of
For machine vibration, cause carbon brush to come off, cause carbon brush unavailable, waste very much.
Utility model content
A kind of carbon brush that the purpose of this utility model is to provide, solve above-mentioned of the prior art one or
It is multiple.
This utility model provides a kind of carbon brush, and including carbon brush body and sheet metal, carbon brush body is trapezoidal
Block, the upper surface of carbon brush body is provided with arcuate groove, and front end face is provided with V-shaped groove, carbon brush body tail end and gold
Belonging to connecting between sheet and have spring and wire, wire passes spring.Such structure reduces in operating process
Friction, extend service life.
In some embodiments, carbon brush body tail end is fixed on by copper sheathing in wire one end.Copper sheathing plays
Reinforcement effect, makes wire be connected with carbon brush body firm, difficult drop-off, and durable, the life-span is long.
In some embodiments, the wire other end is reinforced with keeping off slide block with the junction of sheet metal.So
Wire and sheet metal is made to be connected firmly, difficult drop-off.
In some embodiments, sheet metal includes the metal that sheet metal chieftain and sheet metal chieftain are curled into
Pipe.
The beneficial effects of the utility model are: a kind of carbon brush that this utility model provides, simple in construction, make
With convenient, significantly reduce the friction that carbon brush produces in operation with miscellaneous equipment, extend it and make
Use the life-span.Meanwhile, carbon brush is all connected with firmly with wire, wire with sheet metal, and difficult drop-off is durable,
Extend its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of carbon brush of a kind of embodiment of the present utility model；
Fig. 2 is the perspective view of the carbon brush body of a kind of embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in more detail:
As shown in Figure 1, 2, the utility model discloses a kind of carbon brush, including carbon brush body 1 and sheet metal
2, carbon brush body 1 is trapezoid block, and the upper surface of carbon brush body 1 is provided with arcuate groove 11, and front end face is provided with V
Shape groove 12, the collocation of trapezoid block and V-shaped groove 12 can reduce between carbon brush body 1 and miscellaneous equipment
Friction, and the good stability of V-shaped groove 12, thus extend the service life of carbon brush body 1.
Connecting between carbon brush body 1 tail end and sheet metal 2 and have spring 3 and wire 4, wire 4 is through bullet
Spring 3.Carbon brush body 1 tail end is fixed on by copper sheathing 5 in wire 4 one end, and copper sheathing 5 plays reinforcement effect,
It is firm that wire 4 is connected with carbon brush body 1, difficult drop-off.Wire 4 other end and the connection of sheet metal 2
Place is reinforced with keeping off slide block 6, and sheet metal 2 includes what sheet metal chieftain 21 and sheet metal chieftain 21 were curled into
Metal pipe 22.
Above-described is only embodiments more of the present utility model.Ordinary skill people for this area
For Yuan, on the premise of creating design without departing from this utility model, it is also possible to make some deformation and change
Entering, these broadly fall into protection domain of the present utility model.
