Abstract
The utility model relates to an alternate form carbon brush, including the brush body, brush tube, brush yoke, elastomeric element, lug, tail -hood, sealing washer, gland, because elastomeric element is the conductor with the tail -hood, consequently, the brush body is through elastomeric element and tail cover connected, is connected with the lug indirectly again, is provided with the sealing washer between elastomeric element and the tail -hood, and firm in connection has guaranteed elastomeric element's stability moreover, and simultaneously, elastomeric element will brush to personally experience sth. Part of the body and be in the same place with tail cover connected to through the fixed brush body of brush tube, in the time will brushing the body pressure and advance brush tube, the elastomeric element compressed, brush body wearing and tearing back, the brush body kick -backs under elastomeric element's effect, remedies brush integument wearing parts, thereby feasible the alternate form carbon brush batch production of being convenient for, long service life moreover, the fault rate is low.
Description
Technical field
The utility model relates to electrical equipment, specifically alternate form carbon brush.
Background technology
Carbon brush (Carbonbrush) be also brush, as a kind of slide contact member, is widely used in many electric equipments.Carbon brush mainly contains graphite in products application material, leaching fat graphite, metal (cupric, silver) graphite.Carbon brush is the device of transferring energy or signal between the standing part of motor or generator or other rotating machineries and rotating part, it is generally that pure carbon adds coagulating agent and makes, external form is generally square, be stuck on metallic support, there is spring handle the inside, and it is pressed in rotating shaft, when electric machine rotation, electric energy is flowed to coil by phase changer, because its main component is carbon, be therefore called carbon brush.The effect of carbon brush is mainly to conduction while metal friction.Carbon brush is unlike metal to metal friction conduction, and during metal to metal friction conduction, frictional force can increase, and the place simultaneously joined may be sintered together.Carbon brush then can not because carbon and metal are two kinds of different elements.Its purposes is all used on motor mostly, and shape is also diversified, such as cylindrical, cuboid etc.Nearly all motor all uses carbon brush, and it is the important composition parts of motor.Be widely used in various double current generator, synchronous motor, storage battery DC motor, crane motor collecting ring, various electric welding machine etc.Along with the development of science and technology, the kind of motor and the working condition of use more and more diversified, therefore also expedite the emergence of out the carbon brush of multiple different size shape, but also there is no at present a kind of alternate form carbon brush that convenient, compact structure, making are simple, with low cost of safeguarding.
Utility model content
The utility model, just for above technical problem, provides a kind of alternate form carbon brush that convenient, compact structure, making are simple, with low cost of safeguarding.
The utility model is achieved through the following technical solutions:
Alternate form carbon brush, comprise brush body, brush pipe, brush holder, elastomeric element, lug plate, tail-hood, sealing ring, gland, it is characterized in that in brush holder, being provided with brush pipe, brush pipe box is connected on brush body, brush body is arranged in brush pipe by elastomeric element, elastomeric element is connected with tail-hood, the junction of elastomeric element and tail-hood is provided with sealing ring, tail-hood is arranged on brush holder by gland, elastomeric element and tail-hood are conductor, tail-hood side is connected with lug plate, lug plate arcuately is arranged on below brush holder, lug plate head end stretches out brush holder, elastomeric element initial length is less than brush length of tube.Brush body is cuboid.Elastomeric element is spring.Brush bore is equal with brush body external diameter.
Because elastomeric element and tail-hood are conductor, therefore, brush body described in the utility model is connected with tail-hood by elastomeric element, indirectly be connected with lug plate again, sealing ring is provided with between elastomeric element and tail-hood, be connected firmly, and ensure that the stability of elastomeric element, simultaneously, brush body and tail-hood link together by elastomeric element, and by the fixing brush body of brush pipe, when brush body being compressed into brush pipe, elastomeric element is compressed, after brush body wearing and tearing, brush body resilience under the effect of elastomeric element, make up brush body to be worn part, thus make alternate form carbon brush described in the utility model be convenient to batch production, and long service life, failure rate is low.
The utility model structure is simple, with low cost, easy to use.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-brush body, 2-brush pipe, 3-brush holder, 4-elastomeric element, 5-lug plate, 6-tail-hood, 7-sealing ring, 8 glands-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Alternate form carbon brush, comprise brush body 1, brush pipe 2, brush holder 3, elastomeric element 4, lug plate 5, tail-hood 6, sealing ring 7, gland 8, it is characterized in that being provided with brush pipe 2 in brush holder 3, brush pipe 2 is socketed on brush body 1, brush body 1 is arranged in brush pipe 2 by elastomeric element 4, elastomeric element 4 is connected with tail-hood 6, elastomeric element 4 is provided with sealing ring 7 with the junction of tail-hood 6, tail-hood 6 is arranged on brush holder 3 by gland 8, elastomeric element 4 and tail-hood 6 are conductor, tail-hood 6 side is connected with lug plate 5, lug plate 5 arcuately is arranged on below brush holder 3, lug plate 5 head end stretches out brush holder 3, elastomeric element 4 initial length is less than brush pipe 2 length.Brush body 1 is in cuboid.Elastomeric element 4 is spring.Brush pipe 2 internal diameter is equal with brush body 1 external diameter.
Because elastomeric element 4 and tail-hood 6 are conductor, therefore, brush body 1 described in the utility model is connected with tail-hood 6 by elastomeric element 4, indirectly be connected with lug plate 5 again, sealing ring 7 is provided with between elastomeric element 4 and tail-hood 6, be connected firmly, and ensure that the stability of elastomeric element 4, simultaneously, brush body 1 and tail-hood 6 link together by elastomeric element 4, and fix brush body 1 by brush pipe 2, when brush body 1 is compressed into brush pipe 2, elastomeric element 4 is compressed, after brush body 1 weares and teares, brush body 1 resilience under the effect of elastomeric element 4, make up brush body 1 to be worn part, thus make alternate form carbon brush described in the utility model be convenient to batch production, and long service life, failure rate is low.
Above-mentioned technical conceive and the feature merely illustrating utility model, its objective is and be one of ordinary skilled in the art can be understood the content of utility model and implement according to this, can not limit protection range of the present utility model.The change of every equivalence done by the essence of the utility model content or modification, all should be encompassed in protection range of the present utility model.
