Abstract

The utility model discloses a surface contact carbon brush device with a propulsion function. The device comprises a carbon brush soleplate (1), a carbon brush (2), and a wire (3). The carbon brush (2) is disposed in the carbon brush soleplate (1). The wire (3) is disposed on the carbon brush (2). The carbon brush soleplate (1) is a cubic cavity with an opening on a surface. A surface opposite to the opening surface is provided with a threaded hole. A thrust device (4) is disposed in the threaded hole. A carbon operating surface is arranged as surface contact, compared with point contact carbon brush, operating life of the device is improved. The thrust device is disposed on the carbon brush soleplate. After the carbon brush is worn in operation, the carbon brush can be pushed forward by an adjustable bolt, so not only time of changing the carbon brush is saved, but also the carbon brush can be fully used, thereby cost is saved, and achieving multiple effects of saving time and labor and reducing cost.

Description

A kind of face contact type carbon brush configuration with propulsion functions

Technical field

The utility model belongs to motor accessory technical field, be specifically related to a kind of simple in structure, easy and simple to handle, the face contact type carbon brush configuration with propulsion functions of reliable operation.

Background technology

DC generator, motor and some alternating current generators all can be used carbon brush, and carbon brush is used for electric current to connect with fixed part at rotatable parts conduction, and carbon brush contacts to rotor power supply with the commutator of rotor, and motor just can move, modal is the commutator of motor, also there is straight-line electric car, the brush of electric motor car, the operation principle of carbon brush be mainly utilize with metal friction time conducting function, carbon brush is not as metal to metal when conduction friction, when metal to metal friction conduction, friction may increase, the place of handing-over may be sintered together simultaneously, carbon brush can not, because carbon and metal are two kinds of different elements, because the special nature of carbon brush, on a lot of motors, all use carbon brush, facts have proved: motor reliability of operation, be decided by a great extent the performance of carbon brush, because the carbon brush having is at present much point type contact, wear and tear very fast, frequent with changing, waste time and energy, increase cost, some brush monoblocks are all carbon brush, have regardless of using less than just having wasted, therefore, research and development one can not need frequent replacing, and the device that improves carbon brush utilance is necessary.

Utility model content

It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, the face contact type carbon brush configuration with propulsion functions of reliable operation.

The purpose of this utility model is to realize like this, comprise carbon brush mount pad, carbon brush and wire, in described carbon brush mount pad, carbon brush is set, on described carbon brush, wire is set, described carbon brush mount pad is cube chamber of an opening, the one side that opening surface is relative arranges screwed hole, in described screwed hole, thrust device is set.

The utility model carbon brush working face is set to face contact, and with respect to a contact carbon brush, the utility model has increased working life; On carbon brush mount pad, thrust device is set, after being worn in carbon brush work, can carbon brush be pushed ahead by adjusting bolt, not only can save the time of changing carbon brush, and can make full use of carbon brush, and cost-saving, reach time saving and energy saving and multiple action that reduce costs.

Accompanying drawing explanation

Fig. 1 is the utility model structural representation;

Fig. 2 is that this is Fig. 1 left view;

Fig. 3 is novel another execution mode left view schematic diagram of this use;

In figure: 1-carbon brush mount pad, 2-carbon brush, 3-wire, 4-thrust device, 5-thrust plate, 6-joint.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or the improvement done based on the utility model training centre, all fall into protection range of the present utility model.

As Fig. 1 ~ 3 show, the utility model comprises carbon brush mount pad 1, carbon brush 2 and wire 3, the interior carbon brush 2 that arranges of described carbon brush mount pad 1, on described carbon brush 2, wire 3 is set, described carbon brush mount pad 1 is cube chamber of an opening, the one side that opening surface is relative arranges screwed hole, and thrust device 4 is set in described screwed hole.

Described thrust device 4 is bolt, in described screwed hole, bolt is set, the interior thrust plate 5 that arranges of described carbon brush mount pad 1, and the setting vertical with thrust bolt 4 of described thrust plate 5, described carbon brush 2 is arranged at the active side of the thrust plate 5 in carbon brush mount pad 1.

Described carbon brush mount pad 1 is cylinder cube chamber or hexahedron cube chamber.

On described carbon brush mount pad 1, wiring hole is set, described wire 3 passes through wiring hole, described wire 3 and wiring hole matched in clearance.

On described thrust plate 5, wiring hole is set, described wire 3 passes through wiring hole.

Described wire 3 power connection ends arrange joint 6.
