Definitions

  • the invention relates to a carbon brush for electrically contacting a relative to the carbon brush moving contact structure, in particular a commutator of an electric motor with a brush body formed from a carbonaceous material, wherein the brush body is provided on its contact surface facing the contact structure with a grinding device, and a method for manufacturing such a carbon brush.
  • Carbon brushes of the type mentioned above which serve in particular for making electrical contact with a moving relative to the carbon brush electrical contact structure, such as a commutator of an electric motor, by means of a sliding contact between a contact surface of the carbon brush and the contact surface of the commutator are well known. Also known are the resulting from this particular type of electrical contact adverse effects, which are due in detail to different causes.

  • the arrangement of the grinding device on the end face is realized by means of an adhesion promoter, which produces a mechanical connection between an abrasive abrasive grain, so for example a pumice stone, and the end face.
  • the end surface of the brush body designed according to the surface of the contact structure on the one hand in its surface topography is not affected by the grinding device. This has the consequence, in particular, that, after consumption of the grinding device consuming itself by the sliding contact with the contact structure, the end face comes into contact with the contact structure over its full area from the beginning.
  • the entire cross section of the carbon brush is available for the introduction of current into the contact structure without an increase in the contact resistance due to a reduction in the contact area dimension.
  • the grinding device has a distribution of an abrasive grain applied to the Stirnf kaue by means of the adhesion promoter, after a first contact between the end face of the brush body and the contact structure ensures that the electrical properties of the used for the production of the brush body carbonaceous material fully to Are available, without that after initial contact of the face any abrasive additive in the brush body could lead to a deterioration of the electrical properties.
  • the adhesion promoter serves as a positioning structure for the defined spatial arrangement of the abrasive grain. Accordingly, the abrasive grain is added directly distributed in the bonding agent, so that no separate substrate for the defined distributed arrangement of the grain material is needed.
  • the adhesion promoter serves to connect a position structure defining the abrasive grain material in its spatial arrangement to the contact surface.
  • the material for forming the position structure independently of the adhesion promoter, and to choose, for example, as a positioning structure, a substrate with a textile structure or fleece on which the abrasive grain is arranged in a defined grain size and - distribution.
  • the bonding agent and / or the positioning structure are electrically conductive. Accordingly, the abrasive abrasive grain can be selected independently of any electrical properties. In particular, electrical non-conductors can be used, which can be selected solely with regard to their abrasive property.
  • adhesion promoter or the positioning structure may be advantageous to provide the adhesion promoter or the positioning structure with electrically conductive properties, it may be advantageous to provide the adhesion promoter or the positioning structure with an electrically conductive additive, that is to say, for example, carbon fibers embedded in the adhesion promoter or the positioning structure.

  • a brush body formed from a carbonaceous material, including the formation of the end face.
  • a grinding device comprising an abrasive grain material is arranged on the end face by means of a bonding agent applied to the contact surface.

  • in the inventive preparation for producing a carbon brush, which is provided with a grinding device in simple manner can be built on the method for producing a conventional carbon brush, without a post-processing of the contact surface would be necessary.
  • the grinding device formed on the brush body is produced in that the abrasive abrasive grain is added to the adhesion promoter before it is applied to the end face.
  • the grinding device can be produced simply by producing a distribution of the abrasive abrasive grain in the adhesion promoter, for example by adding the abrasive grain material to the adhesion promoter before it is applied to the end face and producing a suspension.
