Abstract
The invention discloses a cone brush which comprises a brush body and a corresponding conductor. Electric conduction is conducted in the form of cone contact between the brush body and the corresponding conductor. The contact surfaces of the brush body and the corresponding conductor rotate relative to each other. The cone brush is mainly used in occasions needing rotating electric conduction. The cone brush has the advantages of low wear and heat, strong conductivity, long life and good stability.
Description
Technical field
The present invention relates to brush designs technical field, specially a kind of conical surface brush.
Background technology
Brush is to make sliding contact with movement parts and forms a kind of conductive component for electrically connecting.Brush be for diverter or
On slip ring, as the sliding contact body for importing and exporting electric current.The effect of brush be just to turn on relative motion two objects it
Between electric current.Most commonly the diverter of motor, also there is electric car, the brush of electric motor car of linear motion.The shape of brush
Different, what is used on motor mostly is rectangle, is placed on brush carrier.There is certain pressure between brush and diverter or slip ring
Power, large-scale brush structure is more complicated, and small-sized brush is just fairly simple.The electric current of brush derives also different, large-scale brush
On have a wire, small-sized Jing is often drawn by elastic conducting strip.The conduction of brush, heat conduction and greasy property are good, and with one
The instinct of fixed mechanical strength and commutation property spark.Brush is widely used in various double current generators, synchronous motor, storage battery
Dc motor, crane motor collecting ring, various electric welding machine etc..With the development of science and technology, the species of motor and use
Working condition it is more and more diversified so that having the brush of various different grades to meet these requirements.
The content of the invention
It is an object of the invention to provide a kind of circular cone brush, it is mainly used in needing the occasion of rotary conductive, its abrasion and
Heating is relatively low, conductive strong, life-span length, good stability.
To realize object above, the technical solution used in the present invention is：A kind of conical surface brush, it includes brush body and correspondence
Conductor, it is conductive in taper-face contact form between the brush body and correspondence conductor；The contact surface of the brush body and correspondence conductor
Between do relative rotary motion.
Further, the contact surface of the brush body is cone (1), and the contact surface of the correspondence conductor is conical recess
(2)。
Further, the contact surface of the brush body is conical recess (2), and the contact surface of the correspondence conductor is cone
(1)。
Further, the cone (1) is the frustum of a cone (4) shape.
Further, the conical recess (2) is provided centrally with centre bore (3).
Beneficial effects of the present invention：
Present invention abrasion and heating are reduced, and impact less, and the life-span is longer, and more preferably, contact area is bigger for stability, conductive
Ability is higher.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is circular cone structure figure.
In figure：1st, cone；2nd, conical recess；3rd, centre bore；4th, the frustum of a cone.
Specific embodiment
In order that those skilled in the art more fully understand technical scheme, the present invention is entered below in conjunction with the accompanying drawings
Row is described in detail, and the description of this part is only exemplary and explanatory, should not there is any restriction to protection scope of the present invention
Effect.
As shown in Figure 1-2, concrete structure of the present invention is：A kind of conical surface brush, it includes brush body and correspondence conductor, described
It is conductive in taper-face contact form between brush body and correspondence conductor；Do relative between the contact surface of the brush body and correspondence conductor
Rotary motion.
Preferably, the contact surface of the brush body is cone 1, and the contact surface of the correspondence conductor is conical recess 2.
Preferably, the contact surface of the brush body is conical recess 2, and the contact surface of the correspondence conductor is cone 1.
Preferably, the cone 1 is the shape of the frustum of a cone 4.
Preferably, the conical recess 2 is provided centrally with centre bore 3.
Generally for the purpose of conduction, there is for a pair relative motion keep the conductor of contact, one of conductor is brush.
Principle one：Under pressure, when the conical surface of relative rotary motion keeps contact, its contact conical surface central area
Relative linear velocity is less, therefore the abrasion to conical surface brush and heating are reduced.
Principle two, under pressure, when the conical surface of relative rotary motion keeps contact, its contact plane central area
Relative bounce is less therefore less to the impact of conical surface brush, and the life-span is longer, and stability is more preferable.
, relative to other contact forms, contact area is bigger, and conductive capability is higher for principle three, taper-face contact.
The present invention is applicable to the occasion of rotary conductive；Vertically, level, inclination, single pair of or multipair or and different type
Brush is combined；The use occasion of ultrahigh speed or high current.
It should be noted that herein, term " including ", "comprising" or its any other variant are intended to non-row
His property is included, so that a series of process, method, article or equipment including key elements not only include those key elements, and
And also include other key elements being not expressly set out, or also include for this process, method, article or equipment institute inherently
Key element.
Specific case used herein is set forth to the principle and embodiment of the present invention, the explanation of above example
It is only intended to help and understands the method for the present invention and its core concept.The above is only the preferred embodiment of the present invention, should
When pointing out due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvement, retouching or change can also be made, it is also possible to will
Above-mentioned technical characteristic is combined by rights；These improve retouching, change or combine, or the not improved structure by invention
Think and technical scheme directly applies to other occasions, be regarded as protection scope of the present invention.
