Abstract
The utility model discloses a motor brush device. The motor brush device comprises a carbon brush rod, a spring, a socket, an electric brush fixing frame, a lead arranged at a top portion of one end of the carbon brush rod, a male tab arranged at a top portion of the lead, a spring fixing block arranged at one end of the carbon brush rod, carbon brush frames arranged at two ends of the electric brush fixing frame, and guide holes arranged at top portions of the carbon brush frames, wherein the spring fixing block is connected with a spring, the male tab at the top portion of the lead is connected with a socket, the socket is connected with the carbon brush frames, the other end of the carbon brush rod is designed to be an arc structure, the carbon brush rod is designed to be an electrochemical type or nonferrous metal type, and a surface of the lead is provided with a wearing resistant insulating layer. An end of the carbon brush rod connected with a commutator is designed to be an arc structure, so service life is long, no wearing damage to the commutator or a collector ring occurs. During an operation process, the motor brush device has properties of no overheat, small noise, reliable assembly and no damage.
Description
Technical field
The utility model relates to a kind of motor brush device of motor and electrical generator fields.
Background technology
Because the rotation of rotor, brush rubs with commutative ring all the time, and also can produce the bright erosion of electric spark in the moment of commutation, so brush is the consumable accessory in the direct current machine.For useful life, the run stability that improves direct current machine and noise and the electromagnetic interference that reduces direct current machine, brshless DC motor has the trend that progressively replaces brush motor.General alternating current machine need not permanent magnetic field, thus do not need commutator, also just need not brush; But the volume of alternating current machine is generally all bigger.The motor that household electrical appliance use generally all is alternating current machine, all there is not brush as electric fan, washing machine, refrigerator, air-conditioning etc., use direct current machine but also have, as many electric shavers, kitchen small electric apparatus, electric bicycle etc. brush being arranged, is exactly that DC motor (not comprising brushless) has.Carbon brush is widely used in many electric equipments as a kind of sliding contact part.
Summary of the invention
Technical problem to be solved in the utility model relates to a kind of motor brush device of motor and electrical generator fields.
The utility model is achieved through the following technical solutions: a kind of motor brush device of the present utility model, comprise carbon brush rod, spring, socket and brush fixed mount, and be arranged on the lead at carbon brush rod one end top, and be arranged on the inserted sheet of wire top, and be arranged on the spring fixed block of carbon brush rod one end, and be arranged on the carbon brush holder at brush fixed mount two ends, and be arranged on the pilot hole at carbon brush holder top, described spring fixed block connects spring, the inserted sheet gang socket of described wire top, described socket connects carbon brush holder.
Further, the described other end is arc shape, and carbon brush is contacted well with commutator, and a side is provided with cleaning brush, is easy to maintain the carbon brush rod.
Further, described carbon brush rod can electrochemical class or non-ferrous metal class.
Further, described conductive line surfaces is provided with the abrasion-proof insulating layer, can increase the useful life of lead, reduces production cost.
Further, described carbon brush holder is provided with buckle.
The beneficial effects of the utility model are: because the carbon brush rod is made as the arc shape long service life with the commutator link, and do not wear and tear commutator or collector ring, during its operation, not overheated, noise is little, and assembling is reliable, and is not damaged.
Description of drawings
In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.
Fig. 1 is a kind of motor brush apparatus structure schematic diagram of the present utility model;
Fig. 2 is the utility model carbon brush structure schematic diagram.
Description of reference numerals:

Embodiment
As Fig. 1-shown in Figure 2, a kind of motor brush device of the present utility model, comprise carbon brush rod 4, spring 8, socket 5 and brush fixed mount 1, and be arranged on the lead 9 at carbon brush rod 4 one end tops, and be arranged on the inserted sheet 6 at lead 9 tops, and be arranged on the spring fixed block 7 of carbon brush rod 4 one ends, and be arranged on the carbon brush holder 2 at brush fixed mount 1 two ends, and be arranged on the pilot hole 3 at carbon brush holder 2 tops, described spring fixed block 7 connects spring 8, inserted sheet 6 gang sockets 5 at described lead 9 tops, described socket 5 connects carbon brush holder 2.
Wherein, described carbon brush rod 4 other ends are arc shape, and carbon brush is contacted well with commutator, and a side is provided with cleaning brush 11, are easy to maintain the carbon brush rod.
Described carbon brush rod 4 can electrochemical class or non-ferrous metal class.
Described lead 9 surfaces are provided with the abrasion-proof insulating layer, can increase the useful life of lead 9, reduce production cost.
Wherein, between 1.1kg～2.5kg, the differential pressure difference between each carbon brush should be in 5% usually for the spring unit pressure, and spring pressure is excessive, can cause the mechanical wear of carbon brush to increase; Spring pressure is too small simultaneously, though friction is little between carbon brush and slip ring, loose contact is easy to generate spark.
Described carbon brush holder is provided with buckle 10, is easy to fixed installation.
The beneficial effects of the utility model are: because the carbon brush rod is made as the arc shape long service life with the commutator link, and do not wear and tear commutator or collector ring, during its operation, not overheated, noise is little, and assembling is reliable, and is not damaged.
The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
