Definitions

  • the invention relates to a reinforcement rope made of metal wires, preferably steel wires, for elastomeric products, consisting of at least two strands stranded together, each consisting of two or more wires, at least one outer strand consisting of two or more core wires wound helically by at least one strand loop wire.
  • Such a reinforcement rope is known from BE-A-655 590.
  • this reinforcement rope several non-preformed metal wires are laid parallel to strands and helically wrapped by a strand loop wire. Several of these strands can be combined to form a reinforcement rope.
  • Such reinforcement ropes which consist of several strands, are always used in elastomeric products when the elastomeric products are to be subjected to an increased load capacity.
  • the individual wire diameters are usually 0.12 to 0.5 mm.
  • the reinforcement ropes, which consist of several strands, are used when the embedding of the individual strands in the elastomeric product becomes very labor-intensive.
  • the known reinforcement rope has the advantage that when it is embedded in the elastomeric material, it can also get into the core areas of the ropes, so that no capillaries can be formed from the wires, which lead to undesirable corrosion if the surface of the composite material is damaged up to the rope position would.
  • the strand wrap wires do not contribute to the strength of the rope.
  • this object is achieved by a reinforcement rope of the type mentioned above, which is characterized in that the strands are helically wrapped by at least one rope wrapping wire and / or at least one rope wrapping strand, and in the strands and / or in the rope wrapping strands the core wires and the Strands wrapping wires have a helical shape of the same pitch, the same pitch angle and the same direction of rotation, and the core wires of a strand are arranged bundled almost in phase.
  • Rope wrap wires for reinforcement ropes per se are known for example from DE-PS 803 801. These have the task of preventing the reinforcement rope from splicing. In this respect, the rope wrap wire must be tightly wrapped around the reinforcement rope. In this respect, the loop wire usually acts against penetration of the elastomeric product.
  • the metal wires should bond well with the elastomeric material. However, they can also be coated with a second metal, plastic or another material, with a good tendency to bind between the metal wire and the coating material on the one hand and the coating material and elastomeric material on the other hand. Wires made of steel, usually made of carbon steel, are also particularly suitable, but also made of other types of steel, for example made of alloyed or high-alloyed steel with a low Fe content. Steel wires coated with brass are preferred.
  • External strands are understood to be the strands that are visibly on the outside of the finished reinforcement rope.
  • the core wires of the strands and / or the rope wrap strands are arranged next to one another and against one another such that each of the core wires is in parallel linear contact with at least one other core wire.
  • the contact line therefore runs parallel to the direction of the core wires.
  • These strands are known as reinforcement ropes in simple stranding from DE-OS 26 19 086.
  • the reinforcement ropes have been found to be particularly favorable for use as reinforcement ropes in elastomeric products, since the loop wire also has a supporting function and, moreover, the elastomeric material also penetrates particularly well into the core area of the rope when the rope is embedded, and thus also corrosion of the wires is largely prevented in the case of severe damage.
  • the strands and the rope wrapping wires and / or rope wrapping strands are of helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the strands are arranged bundled almost in phase.
  • the strand wrap wires are arranged out of phase with the core wires, preferably shifted by half a pitch length.
  • the preferred lay length for the second stranding is 10 to 30 mm.
  • one or more individual wires can also be installed in the reinforcement rope.
  • the reinforcement rope according to the invention consists of three to seven strands, up to four rope wrap wires and / or up to four rope wrap strands.
  • strands are understood to be strands in the reinforcement rope, which are generally present in a larger number than the rope-wrapping strands.
  • strands and rope-wrapping strands there can also be the same number of strands and rope-wrapping strands, one group of strands and the other group of rope-wrapping strands being named for distinction.
  • the strands and / or the rope wrapping strands contain two to eight core wires; however, more core wires are also possible.
  • the strands and / or the rope wrapping strands generally contain up to four strand wrapping wires, a larger number also being possible here.
  • Core wires are understood to be those wires in the strand or rope wrap strand which are generally in the majority.
  • Strand wrap wires are understood to be those wires in the strand or rope wrap strand which are generally in fewer numbers.
  • the strands or the rope wrapping strands can, for example, contain 3 + 1, 5 + 2, 6 + 3, 7 + 2, or generally n, + n 2 wires, the first number or n, the number of core wires and the second number or n 2 indicates the number of strand wrap wires.
  • the reinforcing ropes according to the invention are preferably used in the manufacture of pneumatic vehicle tires, in particular pneumatic tires for trucks or earth moving machines.
  • FIG. 1 shows the basic structure of a reinforcement rope I according to the invention with four strands 2, which consist of five core wires 3 and two strand strands 4 each, and a rope strapping wire 5.
  • the construction is given as 4 x (5 + 2) + 1.
  • the strands 2 are stranded in a cross lay.
  • the strands 2 are constructed in such a way that the core wires 3 and the strand wrapping wires 4 are of helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the core wires 3 of a strand 2 are arranged in almost the same phase.
  • the core wires 3 and strand wrap wires 4 are only shown in the upper half of FIG. 1. For better clarity, only the strand 2 is shown as a thick cable without stranded wire 4 in the rope network.
  • Figure 2 shows the basic structure of a reinforcement rope 6 according to the invention with seven strands 7, which consist of three core wires 8 and a strand loop wire 9, and a rope loop wire 10.
  • 7 x (3 + 1) + 1 specified.
  • the strands are stranded in a cross lay.
  • the form of representation corresponds to that of FIG. 1.
  • FIG. 3 shows the basic structure of a reinforcement rope 11 according to the invention with seven strands 12, which each consist of two core wires 13 and two strand wrap wires 14, and a rope wrap wire 15.
  • the construction is given as 7 x (2 + 2) + 1.
  • the additional information given in FIG. 1 also applies analogously to FIG. 3.
  • FIG. 4 shows the basic structure of a reinforcement rope 16 according to the invention, in which five strands 17 and two rope wrapping wires 20 are of helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the strands are bundled almost in phase, the rope wrapping wires 20 being around half a pitch length are arranged out of phase with respect to the strands 17.
  • the strands 17 each consist of four core wires 18, each strand 17 being helically wrapped with a strand wrap wire 19.
  • the core wires 18 and the strand wrapping wires 19 have a helical shape with the same pitch, the same pitch angle and the same direction of rotation, and the core wires 18 of a strand 17 are arranged bundled almost in phase.
  • FIG. 5 shows the basic structure of a reinforcement rope 21 according to the invention, in which three strands 22 and one rope wrap strand 25 of helical shape are of the same pitch, same pitch angle and same direction of rotation, and the strands 22 are bundled in almost the same phase, the rope wrap strands 25 is arranged out of phase by half a pitch length with respect to the strands 22.
  • the strands 22 each consist of five core wires 23 and two strand wrapping wires 24.
  • the rope wrapping strand 25 also consists of five core wires 26 and two strand wrapping wires 27.
  • the core wires 23 and 26 and the strand wrapping wires 24 and 24, respectively 27 helical shape of the same pitch, the same pitch angle and the same direction of rotation, and the core wires 23 and 26 of a stranded wire 22 and 25 are arranged bundled almost in phase. It is particularly favorable here if the strand wrap wires 24 and 27 are arranged out of phase by half a pitch length with respect to the core wires 23 and 26.
  • test specimens 28 are produced in which two layers 29, each with fourteen ropes per 32 mm, are vulcanized into two different types of rubber in such a way that the two layers 29 are vulcanized together within a region B of 25.4 mm of the test specimen length.
  • the area limits are 12.5 mm (area A) from one end and 50 mm (area C) from the other end face of the test specimen 28, the cable cross sections being visible on both end faces 30 and 31.
  • the ropes within the rope layers 20 and the two rope layers one below the other lie at a constant distance from one another in the longitudinal direction of the sample.
  • the finished test specimens 28 are immersed on the flat side with the shorter, non-vulcanized side in a 20% NaCl solution 32 in a container at an angle of 45 ° to the bath surface in such a way that the immersion length D of the vulcanized area is 12.5 mm.
  • Several samples of the different types of rope were produced, which were either not at all (immersion time 0 days) or immersed in the 20% NaCl solution for several days.
  • test specimens with reinforcement ropes according to the invention thus behave more corrosion-resistant than the test specimens with comparison ropes.
  • a 7.5 cm long reinforcement rope 36 is embedded in rubber 35, the reinforcement rope 36 being visible on both end faces of the test specimen 34.
  • a sealing washer 37 and a pipe stop piece 38 are embedded in the rubber 35 in each test specimen 34.
  • the test body 34 is connected gas-tight with a compressed air connection piece 41.
  • the compressed air connector 41 is connected via a transition piece 42, a pressure reducing valve 43 and a compressed air line 44 to a compressed air source (not shown).
  • a pipe 39 is connected in a gastight manner, the free end of which is immersed in a tub 45 filled with water 46.
  • the free end is bent upwards and is located under the opening of a measuring cylinder 47 filled with water at the beginning of the experiment, which is also immersed in the water bath 45, 46.
  • the valve 48 With the valve 48, the height of the water column in the measuring cylinder 47 can be adjusted.
  • a pressure of 1 bar is set via the pressure reducing valve 43. If air can penetrate through the test grains into the rubber mass 35 as a result of incomplete embedding of the reinforcement cable 36, the air bubbles that arise rise in the measuring cylinder 47. The amount of air accumulating in the measuring cylinder 47 per unit of time is measured.
  • the reinforcing ropes according to the invention are therefore completely embedded in the rubber mass.
  • FIG. 9 schematically shows the structure of a tire in which reinforcing ropes according to the invention are embedded.
  • the tread of the tire is designated, which is constructed here as a radial tire.
  • two layers 48 and 49 of reinforcing ropes according to the invention are embedded, which run at a certain angle to the circumferential direction. This angle depends on the area of application of the tire.
  • Reinforcement ropes 50 according to the invention are likewise embedded in a carcass 51 perpendicular to the circumferential direction of the tire - in the circumferential direction of the tire cross section.
  • the reinforcing ropes according to the invention can also be embedded in the bead 57.
