Abstract
This invention discloses a rolling type electric brush for providing very small friction control force with contact surface and small resistance coefficient, which contains outer ring, rolling small roundlet and inner ring, which are all made of pure metal with fine conductivity, wherein the inner surface of outer ring rolling contact with rolling small roundlet, the outer surface of inner ring rolling contact with rolling small roundlet, the other part of inner ring connected with support and conductor line. Said invention can be used in surface rolling contact in commutator of motor, slip ring and overhead transmission line of trolley and electric locomotive.
Description
Technical field
The present invention relates to a kind of electrical component, more particularly it relates to a kind of brush.
Background technology
Be used for the brush (also claiming slide plate, piece) that contacts with overhead transmission line on the brush that present known motor is used, electric car and electric locomotive, be electrical carbon product, they are updated in long-term use, have lot of advantages.But because their operating state is the sassafras that rubs that slides without exception, friction is bigger, loss power; Contact-making surface is easy to wear, and it is faster self to wear and tear, and often will change, and wastes time and energy; Simultaneously, it is unfavorable in safety easily to get spark in wear process, makes carbon dust fly upward contaminated environment again.Electric conducting material commonly used such as electrical carbon product and copper, aluminium is bigger than resistance coefficient.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, provide a kind of very little, the rolling type brush that resistance coefficient is also very little with contact surface frictional force.
Rolling type brush of the present invention, comprise the outer ring, rolling roundlet, inner ring all adopt good simple metal of conductivity or alloy to make described outer ring, the commutator of its outer surface and motor, the surface of slip ring or overhead transmission line roll and contact, in order to increase the area of contact-making surface, establish one deck elastic conducting layer again at the outer surface of outer ring, described elastic conducting layer adopts the dense arrangement filament, perhaps dense arrangement sheet metal, perhaps flexible material clamps wire, sheet.The inner surface of described outer ring rolls with the rolling roundlet and contacts, and described rolling roundlet adopts thin-walled pipeline section or ball, and perhaps cylinder preferably adopts the little pipeline section of thin-walled, and its easy deformation can increase the surface area that contacts with Internal and external cycle.
The outer surface of described inner ring rolls with the rolling roundlet and contacts, and position and power supply lead wire join in addition.
Described outer ring, inner ring and biend are equipped with baffle plate, block moving axially of rolling roundlet.
The invention has the beneficial effects as follows: (1) changes into rolling friction to the friction between brush and commutator face, slip ring surface, the power transmission line surface, frictional force is reduced greatly, greatly reduced the abrasion of contact surface, increase the service life exponentially, the economical with materials loss also reduces the loss of power.(2) safe and reliable, nonsparking, do not have carbon dust and fly upward.(3) resistance coefficient of metal is little, and electrical conductance is improved.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
In the drawings, the rolling type brush mainly is made of outer ring 1, rolling roundlet 2, inner ring 3, supporting base 4, lead 5, outer baffle-plate 6, interior plate washer 7 etc.
The outer surface of described outer ring 1 is provided with elastic conducting layer, and present embodiment adopts flexible material to clamp wire, when it is subjected to suitable pressure, can have a lot of wires to be close to contact surface simultaneously, has enlarged conductive area.The inner surface of described outer ring 1 rolls with rolling roundlet 2 and contacts.Described rolling roundlet 2, present embodiment adopt the thin-walled tubule, because wall is thin, and easily deformation, when it is subjected to suitable pressure, can slight ovalization, the contact area of it and outer ring 1, inner ring 3 is increased, help conduction.The outer surface of described inner ring 3 rolls with rolling roundlet 2 and contacts, and the position also is connected with supporting base 4 leads 5 in addition.Plate washer 7 is used to stop moving axially of rolling roundlet 2 in the described outer baffle-plate 6.
Claims (4)
1. rolling type brush, comprise the outer ring, rolling roundlet and inner ring, it is characterized in that, all make with electric conductivity good simple metal or alloy, the inner surface of outer ring rolls with the rolling roundlet and contacts, and the outer surface of inner ring rolls with the rolling roundlet and contacts, and the position of other of inner ring connects bearing support and lead.
