Definitions

  • the invention relates to a spinning or twisting ring for a ring spinning or a ring twisting machine.
  • Spinning rings are used in so-called ring spinning machines and twisting rings in so-called twisting machines.
  • the spinning or twisting rings cooperate with attached ring travelers.
  • the ring travelers entrained by the thread held by the ring traveler, rotate at high speeds on an upper side of the spinning rings, the so-called ring crown, which leads to high loads on the contact surfaces of the spinning rings. For this reason, the quality of the surface is given particular importance in the production of spinning or twisting rings.
  • a ring for a ring spinning or a ring twisting machine must have in addition to a precisely machined shape adapted to the requirements, optimized surface to allow a ring traveler, which rotates at high speed on the ring, a quiet and low-wear as possible. Due to the rapid circulation of the ring traveler on the spinning ring local temperatures of over 400 ° C may occur, which represents an additional requirement on the nature of the surface of a spinning ring.
  • a web is provided, which can end in a foot flange.
  • the ring crown as well as the foot flange, or if the foot flange is missing, are manufactured in various designs, each in shape and geometry adapted to the requirements of the corresponding machine.
  • spinning rings and twisting rings are summarized under the term spinning ring.
  • WO 99/51802 describes the application of a hard chrome coating.
  • Hard chrome plating is applied to components in an electrolytic chrome plating process, mostly for the purpose of wear protection.
  • US 2,970,425 discloses a coating
  • C0NFIRMATI0N C0PY the surface of a spinning ring with an electrolytically applied chromium layer.
  • a disadvantage of this embodiment of a hard chrome coating of the spinning rings is that although a hard and low-wear surface is created, but the running properties of the spinning ring are dependent on a located on the ring surface Faserschmierfilm which is caused by the sliding yarn through the ring traveler.
  • the object of the invention is to provide a spinning ring in which a surface is created, which counteracts the ring traveler only a low running resistance, regardless of a fiber lubricating film.
  • Particles of hexagonal boron nitride are embedded in the hard chromium dispersion layer applied to the core.
  • dispersion particles of hexagonal boron nitride dispersed in the hard chromium dispersion layer statistically, there are always some on the surface of the hard chromium dispersion layer.
  • Hexagonal boron nitride is so-called "white graphite”.
  • White graphite is a material that has very good lubricating properties, combined with the highest temperature stability of all lubricants up to 600 ° C.
  • the exposed hexagonal boron nitride thus provides lubricating material on which the ring traveler can slide with less wear. The running properties can be determined in this way regardless of the presence of a fiber lubricating film through the yarn.
  • the coating process basically takes place the same way as a known electrolytic hard chrome plating process in a corresponding bath.
  • the dispersing agent in this case hexagonal boron nitride, and other chemicals are added to the bath.
  • the Other chemicals cause the hexagonal boron nitride to be better dissolved in the bath and held in suspension, making it easier to incorporate into the growing hard chrome layer.
  • This type of dispersion coatings with a proportion of dispersion materials of up to 40% are known from electroplating.
  • the dispersion solution is kept in motion in the bath.
  • the final result can now be controlled by controlling the parameters current and bath temperature (and stirring speed).
  • the spinning rings to be coated are individually clamped on racks during the coating process.
  • the entire spinning ring is immersed in the coating bath and coated.
  • the metallic coating comprises a hard chrome layer, which is arranged directly on the metallic core, wherein the hard chrome dispersion layer is applied over this first hard chrome layer.
  • the hard chrome layer is not necessarily provided on the entire core.
  • the hard chrome dispersion layer is on the contact surfaces between 0.001 mm and 0.060 mm thick.
  • the hard chrome dispersion layer is made with a thickness between 0.020 mm and 0.040 mm.
  • the surface of the spinning ring In order to allow a smooth running of the ring traveler on the spinning ring, the surface of the spinning ring must be as hard and smooth as possible.
  • the surface of the hard chrome dispersion layer has a surface hardness, measured according to Vickers 0.05, of HV 800 to 1,200.
  • the surface roughness Ra is advantageously at most 0.0003 mm.
  • the hexagonal boron nitride is provided in the hard chrome dispersion layer with a incorporation rate of 1% to 30%, preferably 20% to 30%.
  • the hexagonal boron nitride incorporated in the hard chromium dispersion layer has an average particle size of 0.0005 mm to 0.010 mm.
  • the purity of the hexagonal boron nitride used for the coating is greater than 97%.
  • the hexagonal boron nitride used for the coating has a specific surface area of 4 m 2 / g to 30 m 2 / g.
  • the metallic core of the spinning ring is advantageously made of steel, in particular of a tempered steel. Particularly good properties of the spinning ring, when the hard chrome dispersion layer is polished. As a result, the smallest unevenness in the coated surface can be eliminated.
  • the core of the ring may have a surface that has been polished prior to application of the hard chrome dispersion layer.
  • the core can also be coated with a copper or nickel layer, which in turn is polished and on which the hard chrome dispersion layer is arranged.
  • a hard chrome dispersion layer applied to a polished surface has a very smooth surface, which causes a very smooth running of a ring traveler on the thus hard chromium-plated ring.
