Definitions

  • the invention relates to a ring for spinning and twisting machines with a flange area, a neck area and a shaft area.
  • Such rings are exposed to increased temperatures and increased abrasion during the spinning process due to the frictional contact between the ring flange, rotor and thread. This reduces the service life and the running properties of the ring.
  • the hardened surface also results in a higher thread tension, which is particularly the case in high-speed operation with spindle speeds of more than 20,000 revolutions / min. leads to frequent thread breakage.
  • the object of the invention is therefore to develop a ring for spinning and twisting machines, the service life and running properties of which are considerably improved, so that it can also be used without problems in high-performance spinning machines with a high spindle revolution.
  • At least the flange area of the ring is formed from a fine ceramic material and that after the grain growth the fine ceramic material has a grain size of less than 10 pm and a surface roughness of less than 5 ⁇ m.
  • the ring is made of a metal alloy, e.g. made of carbon steel, then, according to the teaching of the invention, at least the surface of the flange area should have a coating layer made of fine ceramic material, which has the aforementioned grain size and surface consistency.
  • rings made of a metal alloy according to the teaching of the invention can also have a non-electrolytic plating layer which is produced as a matrix with a fine ceramic grain smaller than 3 ⁇ m grain size as a eutectoid substance and a nickel alloy which contains nickel phosphorus.
  • Fig. 1 shows a cross section through a preferred embodiment of a ring for a spinning machine according to the invention.
  • the ring 5 comprises a flange part 1, a neck region 2 and a shaft region 4 with a ring rail fitting region 3.
  • At least the part that is in contact with a rotor, that is, the flange portion 1 of the ring, is made by casting in the desired shape, using ceramic grain material selected from oxide, carbide, nitride, boride or other groups, e.g. SiC, Si 3 N 4 , Al 2 0 3 , Zr0 2 , TiC, TiN etc.
  • the ceramic flange thus obtained is subjected to fire treatment at a high temperature to have a hardness of 1000 to 3500 Hv and a grain diameter after the growth of the crystal grain to get less than 10 pm.
  • the neck region 2 and the shaft region 4, which carries the ring rail fitting region 3, consist of carbon steel, alloy steel, light metal or a high polymer material in the desired shape and are produced by mechanical processing or by casting molds.
  • a smooth surface finish is transferred to the surface of the ceramic flange described above by physical or mechanical finishing methods such as cylinder grinding, lapping or polishing etc. so that the surface roughness is less than 5 pm and preferably less than 1 pm.
  • ceramic materials is not limited to the flange area of the ring, but it can be made entirely of the ceramic material.
  • 3A and 3B show a ring for a spinning machine, the flange area of which bears a ceramic coating layer.
  • This ring 5 is made of carbon steel, a steel alloy, light metal, plastic, composite materials or the like.
  • a ceramic coating layer 6 was formed on the surface of the ring where it is in contact with the rotor by a coating method such as CVD (chemical vapor deposition Process) including a plasma spraying process and an optical CVD, PVD (physical vapor deposition process) including vacuum plating and spraying, IVD (ion vapor deposition process), flame spraying, firing, etc.
  • a ceramic coating layer 8 was formed by composite plating, or by uniformly dispersing the ceramic grain, using the ceramic grain 7 as a eutectic substance and a nickel alloy containing nickel and phosphorus as a matrix.
  • the ceramic coating layer described above can be applied to the entire surface of a ring, but it is also sufficient to apply it only to the surface area which is in contact with a rotor, which surface area is subjected to a masking treatment before the coating.
  • Ceramic materials that can be used according to the invention alone or in combination with others are Al 2 O 3 , ZrO 2 , SiO 2 , Ti0 2 , In 2 0 31 ZaO, Cr 2 0 3 , SiO, TiO, MgO, BeO , Th0 2 , etc. as oxide groups, SiC, TiC, TaC, ZrC, WC, HfC, B 4 C, NbC, C (diamond) etc. as carbide group, Si 3 N 4 , TiN, TiC, N. TaN, ZrN , AIN, GaN, BN, InN etc. as a nitride group and TiB 2 , ZrB 2 , HfB 2 , etc. as a boride group.
  • the neck region 2 and the shaft region 4 with the ring rail fitting region 3 were produced mechanically, using carbon steel as the material.
  • the flange portion 1 and the other portions have been joined together by soldering, or by means of an adhesive such as an epoxy resin, cyanoacrylate, etc., to manufacture the ring for a spinning machine according to the invention.
  • the ring thus obtained was examined for wear by a wear testing machine under the following conditions.
  • the ring A shows according to the invention a much smaller increase in the amount of wear over time than the conventional ring B.
  • the flange portion made of silicon carbide (SiC) has high strength, high heat resistance, and high abrasion resistance.
  • the silicon carbide flange portion has almost the same thermal conductivity as the metallic rotor, the heat generated by the sliding of the rotor can easily radiate, which contributes to a reduction in burning and wear of the rotor, and accordingly the lifespan of the runner is extended.
  • the ring was carbored, it was subjected to an ion plating treatment by glow discharge at 1-5 ⁇ 10 -2 torr in a reigning gas atmosphere with C 2 H 2 as a main component to form a ceramic coating layer 6 of a thickness of 1 to 20 ⁇ m with titanium carbide (TiC ) on the surface that is in contact with the runner.
  • a ceramic coating layer 6 of a thickness of 1 to 20 ⁇ m with titanium carbide (TiC ) on the surface that is in contact with the runner.
  • TiC titanium carbide
  • the ring C thus obtained has a hardness of 2500 to 3400 Hv, which is much higher than that of the conventional ring B which has been carburized and hardened, as shown in Fig. 4, which shows the curves of the cross-sectional hardness distribution.
  • the ring C according to the invention shows only about 1/5 of the amount of wear, while the life is more than 5 times.
  • the conventional ring B experiences an increase in thread tension due to the increase in friction between the ring and the rotor, causing yarn breakage, "flying" of the rotor and other troubles while it becomes difficult to run continuously.
  • the ring according to the invention shows a reduction in the coefficient of friction, while no running-in is required and high-speed running can be carried out immediately after starting.
  • FIG. 6 shows a cross section through the ring according to embodiment 3 of the invention.
  • the flange 12 ring 12 shown in Fig. 6 was manufactured by a low carbon steel cutting process.
  • the above ring was subjected to carburizing treatment and surface grinding, it was subjected to a chemical vapor deposition process at a temperature of 850 to 1050 ° C in a gas atmosphere with TiCl 4 , H 2 , CH 4 , N 2 as a main component to form a ceramic coating layer 13A of 2 to 20 ⁇ m in thickness, containing titanium carbide (TiC) and a ceramic coating layer 13B, 1 ⁇ m in thickness, containing titanium nitride (TiN) on the surface which comes into contact with the rotor.
  • TiC titanium carbide
  • TiN titanium nitride
  • Fig. 9 shows a cross section of a ring according to embodiment 4 according to the invention.
  • This ring was made of carbon steel, for example S15CK material, and formed into a simple flange 16 by means of a cutting process. It was subjected to carburization, quenching and surface treatment. A plated nickel layer 17 about 1 ⁇ m thick was applied to the surface of the ring by an electron nickel process, as shown in FIG. 10.
  • FIG. 12 is a modification of the ring according to FIG. 1, a concave region 9 (FIG. 12A) being formed on the underside of the flange region 1, the flange region and the neck region being connected to one another to form the ring.
  • a concave region 9 FIG. 12A
  • connection and the adhesion of the two parts to each other is stronger.
  • the sintered rings described above have a significantly improved abrasion resistance because they carry a single layer of several layers of the ceramic coating on the pore surface of the surface layer area.
  • the spinning belt is drawn off from a drafting system, passes through a thread guide and is fed to the ring spinning machine, a twist being transferred to the belt by the rotor which is held on the ring according to the invention, the thread being placed around the bobbin.
