Abstract
Description
Mehradrige, flexible elektrische Leistung Um bei mehradrigen elektrischen Leitungen, die im Betrieb häufig hin und her bewegt werden, eine ausreichende Flexibilität sicherzustellen, ist es unter anderem üblich, in die Kabelseele der Leitung ein Gleitmittel einzubringen. Hierzu wird beispielsweise ein pulverförmiges Trockengleitmittel wie Talkum verwendet, das mittels staubdichter Trennschichten in den einzelnen Verseillagen der Leitung festgehalten wird (DT-AS 1 101 551). Es ist auch bekannt, ein wachsartiges Gleitmittel auf Silikonbasis zu ver--wenden, mit dem die Adern vor ihrer Verseilung zur Kabelseele überzogen werden (GB-PS 609 366).Multi-core, flexible electrical power To with multi-core electrical Lines that are frequently moved back and forth during operation have sufficient flexibility to ensure it is customary, among other things, to insert into the cable core of the line Bring in lubricant. A powdery dry lubricant is used for this purpose, for example used like talc, using dust-proof separating layers in the individual layers of the rope the line is recorded (DT-AS 1 101 551). It is also known to be a waxy Use silicone-based lubricant to treat the wires before stranding them to be coated into the cable core (GB-PS 609 366).
Bei den bekannten Leitungsaufbauten muß zur Erzielung der gewünschten Flexibilität entweder wesentlich mehr Gleitmittel eingesetzt werden, als an sich benötigt wird, oder es besteht die Gefahr, daß das Gleitmittel allmählich aus den beanspruchten Oberflächenbereichen verdrängt wird.In the known line structures must to achieve the desired Flexibility either significantly more lubricant can be used than per se is needed, or there is a risk that the lubricant will gradually run out of the stressed surface areas is displaced.
Der Erfindung liegt die Aufgabe zugrunde, bei mehradrigen, flexiblen elektrischen Leitungen die inneren Reibungsverhältnisse dauerhaft so zu verbessern, daß die Leitungen auch erhöhten mechanischen Beanspruchungen, insbesondere wechselnden Biegebeanspruchungen, standhalten.The invention is based on the problem of multi-core, flexible electrical lines to permanently improve the internal friction conditions in such a way that that the lines also increased mechanical stresses, especially changing ones Withstand bending loads.
Zur Lösung dieser Aufgabe geht die Erfindung von einer Leitung mit gummi- oder kunststoffisolierten Adern aus, bei der auf die Oberfläche der gemeinsam ummantelten Adern ein Gleitmittel aufgebracht ist. Gemäß der Erfindung sind die Adern mit einem lackartigen Gleitmittel überzogen.To solve this problem, the invention is based on a line rubber or plastic insulated cores, in which on the surface of the joint coated cores a lubricant is applied. According to the invention, the Cores coated with a varnish-like lubricant.
Bei einer gemäß der Erfindung ausgebildeten Leistung ist demnach jede Ader mit einer dünnen Schicht eines festen, auf der Aderoberfläche fest haftenden Gleitmittels überzogen. Damit ist gewährleistet, daß nur geringe Gleitmittelmengen verwendet werden müssen und daß stets ein Gleitmittelbelag an den beanspruchten Oberflächenbereichen vorhanden ist.In a service designed according to the invention, therefore, each Vein with a thin layer of a solid, firmly adhering to the vein surface Coated with lubricant. This ensures that only small amounts of lubricant must be used and that always a lubricant coating on the claimed Surface areas is present.
Geeignete lackartige Gleitmittel sind insbesondere molybdänhaltige Gleitlacke sowie Gleitlacke auf der Basis von Polytetrafluoräthylen, wie sie an sich bekannt und im Handel unter den Bezeichnungen "Molykote 321 R" und "Molydur 523 erhältlich sind. Das Aufbringen dieser Gleitlacke auf die Oberflächen der Adern erfolgt zweckmäßig in einem Durchlaufverfahren vor dem Verseilen der Adern zur Kabelseele. Hiertei können die Adern ein Becken oder einen Trog durchlaufen, in dem der Gleitlack als Lösung enthalten ist; es besteht auch die Möglichkeit, das lackartige Gleitmittel durch Aufsprühen auf die Aderoberfläche aufzubringen.Suitable lacquer-like lubricants are in particular those containing molybdenum Bonded coatings and bonded coatings based on polytetrafluoroethylene, such as those at known and commercially available under the names "Molykote 321 R" and "Molydur 523 are available. The application of these lubricating varnishes to the surfaces of the veins expediently takes place in a continuous process before stranding the cores to form the cable core. Here, the veins can run through a basin or trough in which the lubricant varnish is included as a solution; there is also the possibility of the varnish-like lubricant to be applied by spraying onto the vein surface.
Ein Ausführungsbeispiel einer gemaß der Erfindung ausgebildeten vieradrigen elektrischen Leistung ist in der Figur dargestellt.An embodiment of a four-wire formed according to the invention electrical power is shown in the figure.
Die Leistung besteht aus den vier miteinander verseilten Adern 1 bis 4, auf die ein Innenmantel 5 und ein Außenmantel 6 extrudiert ist. Jede Ader besteht aus dem Zweiter 10 und der Aderisolierung 11, auf die eine Schicht 12 eines lackartigen Gleitmittels aufgebracht ist.The power consists of the four cores 1 to stranded together 4 on which an inner jacket 5 and an outer jacket 6 are extruded. Every vein exists from the second 10 and the core insulation 11, on which a layer 12 of a lacquer-like Lubricant is applied.
Die im Rahmen der Erfindung vorgesehene lackartige Gleitmittelschicht kann bei allen flexiblen elektrischen Leitungen zur Anwendung gelangen, bei denen Gummi- oder Kunststofflächen aufeinander reiben. Dies gilt unabhängig vom Aufbau der Leitung und von den verwendeten Isolierwerkstoffen. Als Isolierwerkstoffe kommen insbesondere natürliche und synthetische Kautschuke, Polyvinylchlorid, Polyäthylen, sowie Copolymerisate des Äthylen in Betracht. Gegebenenfalls kann die vorgesohene Schicht eines lackartigen Uberzuges auch auf andere Elemente der Kabelseele aufgebracht werden.The lacquer-like lubricant layer provided in the context of the invention can be used for all flexible electrical cables where Rub rubber or plastic surfaces against each other. This applies regardless of the structure the cable and the insulating materials used. Come as insulating materials in particular natural and synthetic rubbers, polyvinyl chloride, polyethylene, as well as copolymers of ethylene into consideration. If necessary, the above Layer of a lacquer-like coating is also applied to other elements of the cable core will.
