Definitions

  • the invention relates to a ring traveler for ring spinning or ring twisting machines.
  • Ring travelers of ring spinning and ring twisting machines are operated at high speeds (30 to 50m / s) with which they move on the rings of the corresponding machines. Both the contact area between ring traveler and ring and the contact area between ring traveler and thread are subject to high wear. In order to increase production, higher running speeds of the ring rotors are required and, in order to reduce costs, a longer service life of the ring rotors.
  • the object of the present invention is therefore to provide an economically more advantageous ring traveler for ring spinning or ring twisting machines.
  • the ring traveler according to the invention has, at least on its running surfaces with which it comes into contact with the ring when running on a ring of a ring spinning or ring twisting machine, a phosphate layer applied by phosphating, the thickness of which is between 0.05 ⁇ m and 10 ⁇ m, layer thicknesses less than 2 ⁇ m are preferable because their surfaces generally have a lower roughness.
  • the ring traveler can also be completely covered by the phosphate layer.
  • steel is preferably used as the base material for the core of the ring traveler, in particular e.g. high carbon (0.5% - 1.5% C) unalloyed or low alloyed steels.
  • high carbon e.g. 0.5% - 1.5% C
  • Ceramics or special plastics conceivable.
  • the phosphated ring traveler shows a very fine crystalline structure with a very smooth surface when cores are used for phosphating, the surface of which is polished.
  • the phosphate layer applied to the steel core of the ring traveler is preferably an iron, zinc or manganese phosphate layer or a compound thereof with alkali or alkaline earth metals, e.g. Lithium, sodium, potassium, rubidium, cesium, beryllium, magnesium, calcium, strontium, barium, radium. It should be taken into account that on ferrous base material, such as Steel, usually some iron phosphate and possibly iron oxides may be present in the phosphate layer.
  • Phosphate layers that have several cations such as iron manganese or iron zinc phosphate layers
  • their compounds with alkali and alkaline earth metals are advantageous, since these have more advantageous properties with respect to roughness, wear and sliding properties compared to phosphate layers with only one type of cation.
  • Iron zinc and zinc phosphate layers combined with alkaline earth metals are particularly advantageous because of their epitaxial, fine crystalline growth.
  • Phosphate layers which are applied to the ring traveler by spraying and dipping, have particularly good properties. These two manufacturing processes - 3 -
  • Driving also have the advantage that they allow a very efficient production of phosphated ring travelers.
  • the ring travelers described with a phosphate layer can be used both in spinning mills and in twisting mills.
  • Your good running properties, e.g. good sliding and low wear are particularly advantageous in combination with steel rings, but they can also be used on other rings, e.g. can be used on sintered, burnished or coated rings.
  • Cotton can be processed particularly advantageously with the ring traveler according to the invention.
  • the ring traveler with a phosphate layer manages with significantly less fiber lubrication, which is also the case with insufficient lubrication, e.g. allowed in compact spinning, higher spindle speeds and rotor life.
  • the short fibers of the cotton showed a very positive interaction with the phosphate layer of the ring traveler and further improved the sliding properties. Fibers, fiber debris and cotton wax are therefore excellently suitable as fiber lubrication for the ring traveler according to the invention.
  • other fibers, natural or synthetic fibers can also be processed with the ring traveler, since it can also be used with additional lubricants (impregnation), such as e.g. with molybdenum disulfide lubricants.
  • the phosphated ring traveler is explained by way of example with reference to FIGS. 1 to 3. Purely schematically, they show:
  • FIG. 2b shows a section along the line A-A of the in Fig.
  • Fig. 3a shows a fully phosphated ring traveler
  • Fig. 3b shows a section along the line B-B of the ring traveler shown in Fig. 3a.
  • La and lb show two C-shaped ring travelers 10, as are typically used on T-flange rings.
  • 1c to 1f show ear-shaped and hook-shaped ring travelers 10 'as are used, for example, on inclined flange rings.
  • 1 denotes the areas which have the running surfaces 1 'of the ring traveler 10, 10' during operation.
  • both flanks a, b can become the running surface 1 ', whereas in the case of ear-shaped or hook-shaped ring travelers 10', the area of the running surface 1 is clearly defined by the shape.
  • ring travelers 10, 10 'of the most varied embodiments and suitable for the most varied ring shapes are suitable for being produced as phosphated ring travelers.
  • an inner side of the ring traveler 10, 10 ′ designated with 3 must be wear-resistant and with good sliding properties - 5 -
  • FIGS. 2a and 2b show a C-shaped ring traveler 10 as an example, which only in the area of its eventual running surfaces 1 ', and here only on the end faces 2 and the inside 3, but not on an outside 4 a phosphate layer 5 is coated. Since the ring traveler can tilt laterally during operation, it is advantageous in the area of the running surfaces 1 not only to coat the inside 3 which is in direct contact with the ring but also the end faces 2 of the ring traveler 10 with the phosphate layer 5, but this is not is absolutely necessary. In the shoulder area 6 of the ring traveler 10, which does not come into contact with the ring during operation, the ring traveler 10 has no phosphate layer 5.
  • the core 7 of the ring traveler 10 consisting of a base material, such as steel, is thus visible on the outside 4 and in the shoulder region 6 of the ring traveler.
  • 3a and 3b show an example of a C-shaped ring traveler 10 which is completely coated with a phosphate layer.
  • Known phosphating processes can be used to produce the phosphated ring traveler 10, 10 ', which include, for example, the following process steps:
  • the surface of the core 7 of the ring traveler 10, 10 ' which e.g. is made of steel, is advantageously finely polished, e.g. to H to 1 ⁇ m, since the surface of the applied phosphate layer 5 roughly corresponds to the roughness of the surface of the core 7.
  • the phosphate layer 5 is applied to the ring traveler 10, 10 'by immersing the ring traveler 10, 10' in a bath of phosphate solution or by spraying with such a solution. After the phosphate layer 5 has been applied to the ring traveler 10, 10 ', the ring traveler 10, 10' is rinsed again and possibly dried.
  • the layer thickness and layer properties of the phosphate layer 5 are known to depend on the parameters selected during production, such as the type of cleaning agent, the composition of the phosphate solution, the exposure time and temperature of the cleaning and phosphating solution.
