  • the invention provides a novel slip ring element whose construction is cost-effective, and by which the quality, in particular the life or the reliability of slip ring elements is significantly increased. This is done by the slip ring elements solved according to claim 5.
  • the invention is based on the idea that contact rings of a slip ring element already finally worked on their shell sides and / or be coated before the slip ring elements are assembled or to be assembled.
  • the functionally relevant surfaces on the shell sides The contact rings need a stringing together and bonding the contact rings and after a removal of material of the contact rings in Area of their frontal touch no longer be edited.
  • the contact rings in the isolated state with a high quality for the function of a slip ring unit Surface can be provided.
  • the contact rings can with advantage in one Bulk material or drum processes are treated or coated while in conventional manufacturing processes, the entire slip ring element must be treated or coated. If the coating or Machining process is faulty, there is the whole Slip ring element to be seen as a committee. In the method according to the invention On the other hand, individual faulty contact rings can be eliminated. so the damage here is very limited.

  • a contact ring 1 is created, such as it is shown in the figure 1.
  • the contact ring 1 has an axis Y, which orthogonal to an imaginary diameter line of the contact ring. 1 stands, and around which contact ring 1 will turn in later operation.
  • the contact ring 1 is made of a blank made of a copper-zinc-lead alloy manufactured, passing through a central bore through the body of the contact ring 1 the inside I is limited.
  • the surface of the inside is machined highly accurately according to the requirements of a fit.
  • the Face F is designed by a turning process stepped, so that webs 1.1 and the frontal faces F1 and F2 arise.
  • the subarea F1 represents so to speak the front side of the web 1.1, while the partial surface F2 is the recessed face of the contact ring.
  • the shell side A is the curved outside of the contact ring 1. In the shell side A was incorporating a diamond turning process, a V-groove 1.2 is incorporated. When working on the shell side A was taken to ensure that This is a very high surface quality, especially low roughness having.
  • the thus processed contact rings 1 are then with an extremely thin Gold layer coated.
  • the contact rings 1 a extremely efficient and cost-effective bulk material coating process subjected.
  • the manufacturing step S1 is thus with comparatively little effort in an early manufacturing phase a qualitative high-quality surface of the contact ring 1 created, as for the function a slip ring unit is very well suited.
  • a later processing the shell side A, z. B. after the assembly of the contact rings 1, is therefore not necessary anymore.
  • the contact ring 1 has an outer diameter of only 6.3 mm, while the webs 1.1 a width in the axial direction of each have 0.25 mm.
  • the contact rings 1 according to Figures 2a and 2b in the manufacturing step S3 on an inner body 2 of the slip ring element, as injection-molded plastic part is executed, applied or postponed.
  • the contact rings 1 are arranged or aligned so that whose axes Y point in the same direction, namely in the direction the central axis X of the slip ring element. In the example shown even fall After installation, the axes Y of the contact rings 1 congruent with the central axis X of the slip ring element together.
  • the inner body 2 has, inter alia, two longitudinal ribs 2.4, and at one Side a centric hollow cylindrical pin 2.2 with an opening 2.7.
  • the longitudinal ribs 2.4 which run parallel to the central axis X, are in a sub-area by a crosspiece 2.3 to increase the mechanical Stiffness of the inner body 2 connected.
  • the longitudinal ribs 2.4 approximately each have a cross section in the form of a Circular segment.
  • the contact rings 1 on the Longitudinal ribs 2.4 postponed.
  • the outer diameter of the circle segments is dimensioned according to the inner diameter of the contact rings 1, so that the contact rings 1 in the radial direction backlash along the longitudinal ribs 2.4 can be moved.
  • the contact rings 1 touch the Inner body 2, or its longitudinal ribs 2.4 only at a portion of their Inside I.
  • the cables 7 Before or during the application of the contact rings 1 on the inner body. 2 the cables 7 through a hollow cylindrical opening 2.6 of the inner body 2 threaded.
  • the contact rings 1 in this manufacturing step S3 strung together so that these in the area of the webs 1.1 end face touch, or the surfaces F1 of the contact rings 1 touching each other be pushed.
  • the inner body 2 has a bearing seat 2.1, which a paragraph 2.11 with two stop surfaces C, D. Through this Paragraph 2.11, in particular by the stop surface C, becomes an axial Securing the contact rings 1 allows, so that the contact rings 1 at Line up only against the stop surface C of this paragraph 2.11 must be pushed to a mutual frontal contact reach all contact rings 1. This facilitates or accelerates the Manufacturing process.
  • This interior is at least partially miter in the production step S4 an adhesive 5 filled.
  • the adhesive 5 through the Opening 2.7 of the pin 2.2 is virtually injected into the interior.
  • the comparatively viscous adhesive 5 flows through the opening 2.7 in the interior and moves there through the channels 2.5 to the insides I and the front-side partial surfaces F2 of the contact rings 1 out.
  • the gaps which are radially within the webs 1.1 of the contact rings 1, at least partially filled with the adhesive 5.
  • the volume of the adhesive 5 to be introduced is for this production step S4 so dimensioned that the interior on the one hand sufficiently with the adhesive. 5 is filled, on the other hand, but no glue 5 at the opposite opening 2.6 of the slip ring element emerges. After filling the interior with the adhesive 5 is allowed to cure the adhesive 5, so that the finally stick together contact rings 1 together. On In this way, a slip ring element is created, which after the manufacturing step S4 is represented according to the figure 3.
