Definitions

  • the invention relates to a wire rope, in particular in Normalmachart, with a, in particular stranded on a core strand, inner strand layer, an outer strand layer and a plastic padding under the outer strand layer.
  • Such wire ropes are known in various designs.
  • the padding reduces the surface pressure on wire crossovers between the outer and inner strand layers.
  • a plastic interlayer is produced by extruding a thermoplastic material on a core rope and later the outer strand layer is stranded under impressions in the, reheated, plastic.
  • the DE 23 26 742 has the production of a plastic liner in a wire rope in parallel design to content, in which the inner and the outer strand layer must be stranded in one operation.
  • the plastic is previously extruded on the individual strands of the inner strand layer. When stranding, it is heated and squeezed out to a continuous liner.
  • the invention has for its object to provide a further type of upholstery, which requires the least possible effort.
  • this purpose is achieved in that in a wire rope of the type mentioned, the outer wires of the strands of the inner strand layer are coated with plastic.
  • Wires can easily be encased in plastic during manufacture, e.g. in the dipping process. Their warehousing in the wire rope shop has at only 15% of the weight fraction in the wire rope no significant cost-causing scope. The production of the strands and their stranding is not burdened with complications. There are no special operations added.
  • the plastic will usually be a not too soft thermoplastic. Duroplast but also come into consideration.
  • the drawing shows an embodiment of the invention. It shows a wire rope in a cross section.
  • the outer wires 6 of the strands 3 are provided with a plastic sheath 7.
  • the plastic sheath 7 lies between the metal surfaces. It reduces the surface pressure.
  • the stranding of the outer strand layer in Normalmachart can be done in the same direction as the inner strand layer with different lay length or in the opposite direction of rotation.
  • the invention measure especially advantageous. Even with parallel stranding of the inner and outer strand layer, the measure is advantageous.

Description

  • Die Erfindung betrifft ein Drahtseil, insbesondere in Normalmachart, mit einer, insbesondere auf einer Kernlitze verseilten, inneren Litzenlage, einer äußeren Litzenlage und einer Kunststoffpolsterung unter der äußeren Litzenlage.
  • Solche Drahtseile sind in verschiedenen Ausführungen bekannt. Die Polsterung vermindert die Flächenpressung an Drahtüberkreuzungen zwischen der äußeren und der inneren Litzenlage.
    Nach der DE 22 02 823 wird eine Kunststoff-Zwischenlage erzeugt, indem ein thermoplastischer Kunststoff auf einem Kernseil extrudiert wird und später die äußere Litzenlage unter Eindrücken in den, wieder erwärmten, Kunststoff verseilt wird.
  • Die DE 23 26 742 hat die Erzeugung einer Kunststoff-Zwischenlage in einem Drahtseil in Parallel-Machart zum Inhalt, bei dem die innere und die äußere Litzenlage in einem Arbeitsgang verseilt werden müssen. Der Kunststoff wird vorher auf den einzelnen Litzen der inneren Litzenlage extrudiert. Beim Verseilen wird er erwärmt und zu einer durchgehenden Zwischenlage ausgequetscht.
  • In der DE 39 34 270 ist vorgeschlagen, das gleiche Ergebnis nur mit einer kunststoffummantelten Kernlitze zu erzielen. Der Kunststoff soll sich beim Verseilen von der Kernlitze aus zwischen den Litzen der inneren Litzenlage herausquetschen bis an die äußere Litzenlage.
  • Der Erfindung liegt die Aufgabe zugrunde, eine weitere Art der Polsterung zu schaffen, die einen möglichst geringen Aufwand erfordert.
  • Gemäß der Erfindung wird dieser Zweck dadurch erfüllt, dass bei einem Drahtseil der eingangs genannten Art die Außendrähte der Litzen der inneren Litzenlage mit Kunststoff ummantelt sind.
  • Mit diesem örtlich und mengenmäßig beschränkten Einbringen von Kunststoff in das Drahtseil wird an allen Drahtüberkreuzungen zwischen der äußeren und der inneren Litzenlage und darüber hinaus zwischen der inneren Litzenlage und der Kernlitze oder einer nächstinneren Litzenlage eine polsternde Kunststoffzwischenschicht platziert.
  • Der Aufwand dafür ist, insgesamt betrachtet, geringer als bei allen bisherigen Lösungen. Drähte können leicht schon beim Herstellen mit Kunststoff ummantelt werden z.B. im Tauchverfahren. Ihre Lagerhaltung in der Drahtseilerei hat bei z.B. nur 15% des Gewichtsanteils im Drahtseil keinen wesentliche Kosten verursachenden Umfang. Das Herstellen der Litzen und deren Verseilung wird nicht mit Verkomplizierungen belastet. Es kommen keine besonderen Arbeitsgänge hinzu.
  • Der Kunststoff wird in der Regel ein nicht allzu weicher Thermoplast sein. Duroplaste kommen aber ebenfalls in Betracht.
  • Die Zeichnung gibt ein Ausführungsbeispiel der Erfindung wieder.
    Sie zeigt ein Drahtseil in einem Querschnitt.
  • Auf einem Kernseil aus einer Parallelschlaglitze 1 1 +8+8 als Kernlitze und einer Litzenlage 2 aus sechs Parallelschlaglitzen 3 1+8+8 ist eine äußere Litzenlage 4 aus acht Parallelschlaglitzen 5 1+(6+6)+12 in Normalmachart verseilt.
  • Die Außendrähte 6 der Litzen 3 sind mit einer Kunststoffummantelung 7 versehen.
  • An allen Stellen 8, an denen die Litzen 3 Berührung mit den Litzen 5 oder der Kernlitze 1 haben, liegt die Kunststoffummantelung 7 zwischen den Metalloberflächen. Sie vermindert die Flächenpressung.
  • Die Verseilung der äußeren Litzenlage in Normalmachart kann im gleichen Drehsinn wie die innere Litzenlage mit unterschiedlicher Schlaglänge oder im entgegengesetzten Drehsinn erfolgen. Für den letzteren Fall ist die Erfindungsmaßnahme besonders vorteilhaft. Auch bei Parallelverseilung der inneren und der äußeren Litzenlage ist die Maßnahme von Vorteil.
