Definitions

  • Chain strand with textile chain links made of twisted belt material
  • the invention relates to a chain strand with interlocking chain links which are constructed from at least one layer of at least one textile belt.
  • the present invention is therefore based on the object of creating an improved textile warp.
  • This object is achieved for the chain strand mentioned at the outset in that at two successive points in the circumferential direction the at least one layer of the belt is rotated by half a turn or an odd multiple of a half turn in the same direction of rotation around the circumferential direction.
  • Another advantage of the structure according to the invention is that the yarns on the flat sides of the belt come to lie both on the outside and the inside of the chain link and thus have the same length after one revolution of the belt around the circumferential direction.
  • the solution according to the invention can be further improved by the following developments that are independent of one another, are each advantageous in themselves and can be combined with one another as desired.
  • the two twisted points in the chain link can lie opposite one another, in particular with regard to a central opening in the chain link. This results in a symmetrical structure of the chain link, which leads to a structurally easier to control and to more reliable symmetrical loading of the belt.
  • a chain link in each of the chain links of the chain strand that are not located at the end of the chain strand, a chain link can be suspended in the circumferential direction between the twisted points.
  • the non-twisted points of the chain link in such a configuration are those points where the two adjacent chain links of the chain strand are supported or arranged.
  • the belt there may be more or fewer layers of the belt.
  • several, in particular all Layers of the chain link can be wound from a single belt. To do this, the belt is wrapped around the opening several times. The belt can thus form a winding that is twisted in itself at two points around a common opening of the respective chain link.
  • the individual layers of the belt lie completely on top of one another with their flat sides along the circumferential direction.
  • several belts can form the at least one layer. For this purpose, several straps can be wrapped around the central opening one after the other.
  • the ends of a belt preferably lie opposite one another with respect to the layers or in the direction of thickness and overlap.
  • the ends are preferably connected to one another, for example sewn and / or riveted. A position in the sense of this technical teaching extends completely around the central opening.
  • the individual layers can also be connected to one another continuously or at points spaced apart from one another, for example sewn and / or riveted. This improves the structural cohesion of the chain link.
  • FIG. 1 shows a schematic view of a chain strand
  • Fig. 2 is a schematic view of a chain link of the chain strand of FIG. 1.
  • a chain strand 1 is shown, which has a plurality of countries 2 chain links interconnected.
  • the chain links 2 do not have to be constructed identically, but can, as exemplified by the chain link 2a shown in dashed lines, have a different structure and / or a different geometry and / or be made of different materials. At least some of the chain links, however, are preferably constructed as shown by way of example in FIG.
  • FIG. 2 shows a chain link 2 which is constructed from a single textile belt 4.
  • the belt 4 is wound several times around a central opening 8 of the chain link 2.
  • the individual layers 10 preferably lie on top of one another over their entire surface.
  • the chain link 2 thus has several layers 10.
  • the number of layers 10 is arbitrary and can be between 1 and 12. In Fig. 2 three layers are shown for illustrative purposes only.
  • the ends 12 of the belt 4 overlap. This makes it possible to fasten the ends 12 to one another through the layers 10 via a seam 14 and to give the chain link 2 a structural integrity, although it is made of a pliable material. Instead of a single belt, several belts can be wrapped around the central opening 6 one after the other. In addition to or instead of the seam 14, another type of connection of the ends 12 can also be used, for example riveting. Furthermore, at least two, preferably all, layers 10 can be connected to one another at at least one other point in order to increase the structural integrity of the chain link.
  • the belt material is twisted once over all layers by half a turn or an odd multiple of a half turn, i.e. 180 °, 540 °, 900 ° etc. around the circumferential direction.
  • the rotation at the points 16 takes place in the same direction of rotation 18 around the circumferential direction 6.
  • the two points 16 are preferably opposite one another with respect to the opening 8.
  • the chain link 2 is not twisted between the two points 16.
  • the two adjacent chain links suspended in the chain link 2b are preferably located between the points 16, that is, in the non-twisted area.
  • the flat sides 22 of the belt 4 lie on top of one another between the layers 10. Between the points 16, the flat sides point radially inward, towards the opening 8, or radially outward, away from the opening 8. Due to the odd-numbered rotation, one flat side comes out between the points 16 and the other flat side 22 on the outside lie.
  • the twisted points 16 can in particular form the legs and the non-twisted points the bend of the chain link 2.
  • the alternating positioning of the flat side 22 on the inside and outside and the symmetrical structure of the chain link 2 lead to an easily controllable load situation in use, to simple manufacture and to even wear of the chain links 2.
  • the chain strand 1 itself does not have to be made entirely of textile chain links 2, but can also have, for example, metal chain links 2a and / or textile chain links 2a in between, which are shaped and / or constructed differently than the chain links 2.
  • the belt 4 or the belts 4 can be constructed from a wide variety of materials.
  • high-strength fibers and yarns are suitable for the chain link in order to achieve a high breaking strength or tear strength.

Abstract

L'invention concerne un segment de chaîne (1), qui présente une pluralité de maillons de chaîne (2) comprenant au moins une couche (10) constituée d'une sangle textile (4). Le maillon de chaîne (2) est tordu autour de la direction circonférentielle (6) dans le même sens de rotation (18) à deux emplacements (16) espacés l'un de l'autre dans la direction circonférentielle (6), d'un demi-tour ou d'un multiple impair d'un demi-tour. Cela amène à une construction symétrique, une situation de contrainte bien maîtrisable et à une usure uniforme du maillon de chaîne, étant donné que les côtés plats (22) des deux couches (10) situées à l'extérieur pointent entre les emplacements (16) une fois vers l'ouverture (8) et une fois dans le sens opposé à l'ouverture (8).
