Abstract
The utility model relates to a bolt manner carbon brush, including the brush body, brush tube, brush yoke, elastomeric element, bolt, tail -hood, support body, the brush body is the cuboid. Elastomeric element is the spring. Brush tube internal diameter and the external footpath of brush equal. The utility model discloses a bolt is fixed the tail -hood on brush tube, and rethread elastomeric element and brush body coupling because the bolt is the conductor with the tail -hood, consequently, can save the lug, and the bolt is connected with brush tube moreover, and convenient to detach, elastomeric element will brush 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 bolt manner 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 bolt type 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 expedited the emergence of out the carbon brush of multiple different size shape, but also do not had at present a kind ofly to safeguard convenient, compact structure, bolt type carbon brush simple to operate, with low cost.
Utility model content
The utility model, just for above technical problem, provides a kind of and safeguards convenient, compact structure, bolt type carbon brush simple to operate, with low cost.
The utility model is achieved through the following technical solutions:
Bolt type carbon brush, comprise brush body, brush pipe, brush holder, elastomeric element, bolt, tail-hood, support body, it is characterized in that support body is arranged on below brush holder periphery, be provided with brush pipe in brush holder, brush pipe box is connected on brush body, and brush pipe afterbody is provided with tail-hood, bolt is connected with brush pipe through tail-hood, bolt and tail-hood are conductor, and brush body is connected on tail-hood by elastomeric element, and 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.
Tail-hood is fixed on brush pipe by bolt by the utility model, be connected with brush body by elastomeric element again, because bolt and tail-hood are conductor, therefore, lug plate can be saved, and bolt is connected with brush pipe, be convenient to dismounting, 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 bolt type 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-bolt, 6-tail-hood, 7-support body.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Bolt type carbon brush, comprise brush body 1, brush pipe 2, brush holder 3, elastomeric element 4, bolt 5, tail-hood 6, support body 7, it is characterized in that support body 7 is arranged on the peripheral below of brush holder 3, be provided with brush pipe 2 in brush holder 3, brush pipe 2 is socketed on brush body 1, and brush pipe 2 afterbody is provided with tail-hood 6, bolt 5 is connected with brush pipe 2 through tail-hood 6, bolt 5 and tail-hood 6 are conductor, and brush body 1 is connected on tail-hood 6 by elastomeric element 4, and 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.
Tail-hood 6 is fixed on brush pipe 2 by bolt 5 by the utility model, be connected with brush body 1 by elastomeric element 4 again, because bolt 5 and tail-hood 6 are conductor, therefore, lug plate can be saved, and bolt 5 is connected with brush pipe 2, be convenient to dismounting, 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 bolt type 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.
