Sie Erfindung bezieht eich auf Stahldrahteeile mit lasttragenden Paserelementen.The invention relates to steel wire parts with load-bearing Paser elements.
Ein Drahtseil besteht bekanntlich aus mehreren Teilen oder Litzen, die schraubenförmig um ein zentrales Teil, die Seele, gewunden sind. Sie Teile oder Litzen, aus denen ein Stahldrahtseil aufgebaut ist, bestehen aus Drähten bzw. Fasern oder Fasergarnen, die ebenfalls schraubenförmig um ein zentrales Teil oder die Seele angeordnet sind. Sie Seele wie auch eine Anzahl der Litzen können such allein aus Stahldraht oder aus Fasermaterial oder Fasergarnen bestehen, wobei auch eine Kombination aus Stahldraht und Fasern oder Fasergarnen möglich ist.A wire rope is known to consist of several parts or strands that are helically around a central part, the core, are twisted. The parts or strands that make up a steel wire rope consist of wires or fibers or fiber yarns, which are also arranged helically around a central part or the core. You soul like A number of the strands can also consist solely of steel wire or of fiber material or fiber yarn, whereby also a combination of steel wire and fibers or fiber yarns is possible.
Fasern oder Fasergarne werden in der vorstehend angegebenen Kombination bei Drahtseilen angewendet, bei denen eine gute Biegsamkeit des Seils in Verbindung mit einem niedrigen Gewicht im Vergleich zu einem ganz aus Stahldrähten aufgebauten Seil erwünscht ist. DaB bisher fllr solche Kombinationsseile verwendete Material besteht aus natürlichen Fasern, wie Sisal, Manilahanf, Jutehanf, Baumwolle u.dgl., oder aus Kunstfasern, aus Propylen, Nylon 6V Nylon 6.6, Polyestern, Polyvinylchlorid und ähnlichen Fasern aus thermoplastischem und/oder hitzehärtendem Material. Diese Materialien haben physikalische Eigenschaften, wie Bruchfestigkeit und Dehnung, die weit unterhalb der entsprechenden Eigenschaften von Stahldraht liegen.Fibers or fiber yarns are used in the combination indicated above in wire ropes, in which a good flexibility of the rope in connection with a low weight compared to a rope made entirely of steel wires is desired. DaB previously such a combination ropes fllr material used is composed of natural fibers, such as sisal, abaca, jute hemp, cotton, etc., or from synthetic fibers, of propylene, nylon 6 V nylon 6,6, polyesters, polyvinyl chloride and similar fibers of thermoplastic and / or thermosetting Material. These materials have physical properties, such as breaking strength and elongation, which are far below the corresponding properties of steel wire.

Daraus folgt, daß diese Fasern nicht als lasttragende Elemente ! in Seilen fungieren können. Ihre Aufgabe bestand bisher darin, j Träger zu sein für Schmiermittel und/oder Imprägnierungsmittel.· Biese sind erforderlich, um Korrosionen verursachende Feuchtig-| keit abzuhalten, die in das Seil eindringt. Zugleich verhindern die Schmiermittel bzw. Imprägnierungsmittel eine zu große Eei- | bung zwischen den Fasern. Auch werden die Stahldrähte von innen j her gesehmiext, wenn das Stahldrahtseil gebraucht wird. Die Faserseele gewährt wichtige Unterstützung bei der Quer- j Schnittsbeständigkeit gegenüber Quetschungen des Seils. !It follows that these fibers are not used as load-bearing elements! can act in ropes. Up to now, your task has been to be the carrier for lubricants and / or impregnating agents to prevent it from penetrating the rope. At the same time, the lubricants or impregnation agents prevent too much egg | exercise between the fibers. The steel wires are also shielded from the inside when the steel wire rope is needed. The fiber core provides important support for the cross-cut resistance to crushing of the rope. !
Gemäß der Erfindung werden anstelle der bisher Üblichen Fasern ιAccording to the invention, instead of the previously customary fibers ι
nun aromatische Polyamidfasern als Bauteile eines Kombinationsseile vorgesehen. ! Aromatic polyamide fibers are now intended as components of a combination rope. !
Fäden oder Fasern aus aromatischen Polyamiden sind im Gegensatz! zu den vorgenannten Natur- oder Kunstfasern in der Lage, lasttragend zu sein. IThreads or fibers made from aromatic polyamides are in contrast! capable of bearing the load on the aforementioned natural or synthetic fibers to be. I.
Unter aromatischen Polyamidfasern im Sinne der Erfindung sind zu verstehen aromatische Amide, aromatische Polyamidhydrazide und vollaromatisehe Polyester.Aromatic polyamide fibers for the purposes of the invention are to understand aromatic amides, aromatic polyamide hydrazides and fully aromatic polyester.
Beispiele flir aromatische Amide sind: Poly-p-benzamid, Poly-pphenylenterephthalamide und deren Copolymere; insbesondere geeignet ist Poly-p-phenylenterephthalamid.J~Beispiele für aromatische Polyamidhydrazide sind Polymere von p-Aminobenzhydrazid und Terephthaloyldichlorid und Copolymere von p-Phenylendiamin, Terephthaloyldichlorid und Terephthaloyldihydrazid und/oder p-Aminobenzhydrazid.Examples of aromatic amides are: poly-p-benzamide, poly-pphenylene terephthalamides and their copolymers; Poly-p-phenylene terephthalamide is particularly suitable. Examples of aromatic polyamide hydrazides are polymers of p-aminobenzhydrazide and terephthaloyl dichloride and copolymers of p-phenylenediamine, terephthaloyl dichloride and terephthaloyl dihydrazide and / or p-aminobenzhydrazide.
Beispiele vom aromatischen Estern sind Homo- oder Copolyester, die hergestellt werden aus Terephthalsäure und 1,4-Dihydroxybenzol, das mit einem oder mehreren Halogenatomen oder einer oder mehreren Alkylgruppen substituiert sein kann.Examples of aromatic esters are homo- or copolyesters which are prepared from terephthalic acid and 1,4-dihydroxybenzene, which can be substituted with one or more halogen atoms or one or more alkyl groups.

Die Mitverwendung von aromatischem Polyamidmaterial zur Herstellung von Kombinationsseilen gemäß der Erfindung führt zu einer Erhöhung der Bruchlast von 113 %, während gleichzeitig das Gewicht des Seiles um nur 17 % größer ist. Bei gewissen Typen von Stahlseilen, die gemäß der Erfindung aufgebaut sind, kann bei einer Erhöhung des Seilgewichts um nur 3 bis 5 %j verglichen mit in üblicher Weise aufgebauten Drahtseilen, eine Erhöhung der Bruchlast um 40 bis 100 % erzielt werden.Obtained lighter weight and higher breaking strength without affecting the lubricating and impregnating effect. The use of aromatic polyamide material for the production of combination ropes according to the invention leads to an increase in the breaking load of 113 %, while at the same time the weight of the rope is only 17 % greater. With certain types of steel ropes constructed according to the invention, an increase in the breaking load of 40 to 100 % can be achieved with an increase in the rope weight of only 3 to 5% compared to wire ropes constructed in a conventional manner.
Seile nach der Erfindung zeichnen sich durch folgende Vorteile aus:Ropes according to the invention are characterized by the following advantages:
beträchtliche Erhöhung der Bruchlast für den überwiegenden Teil der Drahtseilkonstruktionen,considerable increase in the breaking load for most of the wire rope constructions,
höhere Biegsamkeit mit der Folge der Anwendbarkeit von Windetrommeln mit kleinerem Durchmesser und Baumersparnis, niedrigeres Gewicht im Vergleich zu der Bruchlast bei bekannten Seilkonstruktionen,higher flexibility with the consequence that winding drums can be used with smaller diameter and tree savings, lower weight compared to the breaking load of known ones Rope constructions,
beträchtliche Erhöhung der Bruchlänge von Ankerseilen bei lsndfernen Bohrausrüstungen, Schiffen und TiefSeeschiffen, Vereinfachung der Herstellung von Stahldrahtseilen zufolge der Verringerung der Drähte bedingt durch den Umstand, daß die Seele als lasttragendes Element wirkt.Considerable increase in the breaking length of anchor ropes at remote locations Drilling equipment, ships and deep-sea vessels, Simplification of the production of steel wire ropes due to the reduction in the number of wires due to the fact that the soul acts as a load-bearing element.
