Definitions

  • the invention relates to a spinning rotor for an open-end spinning machine according to the preamble of claim 1.
  • Spinning rotors are on the ones that come into contact with the fibers Surfaces subject to heavy wear.
  • a coating on the surface of the spinning rotor to apply with embedded hard material grains is known.
  • Such one Coating provides, for example, the nickel-diamond coating with the nickel-diamond coating in addition to good wear properties, also good ones Spinning properties of the spinning rotor can be achieved.
  • Coatings with embedded hard material grains are in known various embodiments.
  • DE 197 13 359 A1 describes for example a spinning rotor with a Rotor cup, the inner surface of which is a nickel dispersion layer having a uniform layer thickness, the Concentration of the in the nickel dispersion layer embedded hard material grains, especially in the area of Surface of the nickel dispersion layer on which Fiber sliding surface is significantly less than in the rotor groove.
  • the open-end spinning unit is the fiber collecting groove with one Nickel-diamond coating and the fiber sliding surface with one pure nickel coating.
  • the coatings are in separate coating processes and in separate baths applied.
  • the nickel layer forms in this way corrosion protection on the other surfaces.
  • the nickel-diamond coating is then only on the nickel layer applied in the fiber collecting groove.
  • DE 198 22 265 A1 discloses an open-end spinning rotor a fiber sliding surface with a nickel-diamond coating is provided.
  • This nickel-diamond coating consists of an inner support layer and an outer one Work shift. These are in the inner backing embedded diamond grains larger than those in the outer Working layer embedded diamond grains. The backing layer and the working shift are interlinked.
  • the scraper also consists of a wear-resistant material, for example made of glass fiber reinforced plastic or from a hardened Material like steel. Due to the stress caused by it exerted the scraper on the coated surface of the rotor , pieces can be made from the well-known coating break out. The chipping or chipping occurs uncontrollably. The detached pieces can be so thick that the base material of the spinning rotor is exposed. So that's the Wear protection through the nickel-diamond coating completely interrupted in places. These places can do that Break out further adjacent pieces of the known Favor coating down to the base material.
  • the chipping or breaking out of pieces of the Coating can also be caused by vibrations occurring on the rotor to be triggered.
  • Detaching pieces of the wear protection Coating down to the base material can be done on everyone above-described nickel-diamond coatings occur. The This significantly reduces the service life of the spinning rotor.
  • the spinning rotor according to the invention has a coating at least two layers containing hard grain, between each of which is essentially free of hard grain Interlayer is present.
  • the hard-grain-containing layers advantageously at least 10 ⁇ m thick.
  • the hard-grain-free layers are preferred between 2 ⁇ m and 10 ⁇ m thick.
  • Such a layer thickness of Interlayer has proven to be particularly beneficial for you though basically unwanted but better controlled Detachment process proven to be when breaking out or flaking of a piece of the coating essentially peels off the top layer containing hard grain remains limited.
  • the coating is advantageous from a single one Nickel dispersion bath in which the concentration of the hard material grains distributed therein can be predetermined.
  • the production Spinning rotor according to the invention can thus without interruption and done inexpensively.
  • the application of the coating according to the invention on the Spinning rotor 1 made of steel takes place in a conventional manner a single nickel dispersion bath 2, as in FIG. 1 shown schematically simplified.
  • Such one Nickel dispersion bath 2 in which the concentration of it distributed hard material grains can be specified, for example the already mentioned DE 197 13 159 A1.
  • the Spinning rotor 1 takes in during the coating process Nickel dispersion bath 2 a position in which the Rotation axis of the spinning rotor 1, as shown in Fig. 1, is arranged vertically.
  • the spinning rotor 1 is first in the nickel dispersion bath 2 Electrolessly outside with a thin layer 6 free of hard granules nickel-plated from 1 ⁇ m to 2 ⁇ m. After reaching the desired layer thickness of this nickel layer is in the Trough 3 indicated agitator 4 put into operation.
  • the Nickel dispersion bath 2 is stirred by means of the agitator 4, and there are hard material grains, in the present case Diamond grains, whirled up when standing still Have set agitator 4 on the bottom 5 of the tub 3.
  • the whirled up diamond grains are distributed in the Nickel dispersion bath 2, and it becomes a hard grain Layer 7 made of nickel with embedded diamond grains 8 on the Grain-free layer 6 is formed.
  • the Grain-free layer 9 By reactivating the agitator 4, the Grain-free layer 9 a second layer 10 containing hard material grains of approximately 10 ⁇ m thickness and by deactivating the agitator again layer 11 of approximately 2 ⁇ m, largely free of grain particles applied.
  • the structure of the layers on the surface of the steel existing main body 12 of the spinning rotor 1 is from FIG. 2 seen.
  • the hard-grain-containing layers 7, 10 and Layers 6, 9, 11 which are free of granules can alternatively be formed in in a manner known per se in succession in two separate bands be applied.
  • Spinning rotors remain after breaking out or flaking of pieces of the coating with embedded hard material grains occurred damage to the The surface is different from the usual spinning rotors. This means that the service life of the Spinning rotor 1 when the damage occurs and thus a significant improvement in the economy of the Spinning process.
