Abstract
Description
Die Erfindung bezieht sich auf eine flexible elektrische Leitung für ortsveränderliche Verbraucher, die mindestens zwei jeweils aus einem elektrischen Leiter und einer denselben umgebenden Isolierung bestehende Adern als Verseilelemente aufweist, welche um einen aus Isoliermaterial bestehenden Kern mit in Längsrichtung verlaufenden Dellen, in denen die Verseilelemente liegen, herumverseilt sind, und welche von einem gemeinsamen Mantel aus Isoliermaterial umgeben sind (
Derartige Leitungen werden beispielsweise zum Verbinden von ortsveränderlichen Geräten mit einer Spannungs- bzw. Signalquelle eingesetzt. Ortsveränderliche Geräte können beispielsweise Kräne, Werkzeugmaschinen und Roboter sein. Die Leitungen müssen mechanisch belastbar sein, mit einer auf lange Zeit gleichbleibenden Biegefestigkeit. Sie sollen auch in einem weiten Temperaturbereich gut biegbar bleiben, der beispielsweise zwischen -40 °C und +80 °C liegt. Wenn die Leitungen beispielsweise als Schleppkettenleitungen in der Automatisierungstechnik eingesetzt werden, dann müssen sie auch bei größeren Längen von bis zu 50 m Bewegungen mit erhöhten Geschwindigkeiten von bis zu 5 m/sec in horizontaler Richtung und entsprechenden Beschleunigungen von bis zu 50 m/sec2 auf Dauer unbeschadet überstehen. "Auf Dauer" bedeutet dabei beispielsweise bis zu 5 Millionen Biegezyklen.Such lines are used for example for connecting portable devices with a voltage or signal source. Mobile devices may be, for example, cranes, machine tools and robots. The cables must be mechanically strong, with a constant flexural strength for a long time. They should remain well bendable in a wide temperature range, for example, between -40 ° C and +80 ° C. If the lines are used, for example, as drag chain lines in automation technology, then they must also with larger lengths of up to 50 m movements with increased speeds of up to 5 m / sec in the horizontal direction and corresponding accelerations of up to 50 m / sec 2 on Survive unscathed.

Die bekannte Leitung nach der eingangs erwähnten
Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Leitung so zu gestalten, daß sie ihre Funktionsfähigkeit auch bei größerer Länge und Bewegungen mit hoher Geschwindigkeit und Beschleunigung auf Dauer unbeschadet beibehält.The invention has for its object to make the above-described line so that it maintains its functionality without damage even with greater length and movements with high speed and acceleration over time.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,
- daß in dem Kern zentral ein von einer Schicht aus Isoliermaterial umschlossener nichtmetallischer, zug- und stauchstabiler Träger angeordnet ist,
- daß die Schicht aus Isoliermaterial aus einem auf Dauer elastisch bleibenden, eindrückbaren Material besteht, das die Innenzwickel zwischen den Verseilelementen vollständig ausfüllt, und
- daß die Schicht aus Isoliermaterial von einer Gleitschicht aus einem Material mit gegenüber den Verseilelementen guten Gleiteigenschaften umgeben ist.
- in that in the core a central non-metallic, tensile and compression-stable carrier enclosed by a layer of insulating material is arranged,
- that the layer of insulating material consists of a permanently elastic, compressible material that completely fills the Innenzwickel between the stranding, and
- the layer of insulating material is surrounded by a sliding layer of a material with good sliding properties in relation to the stranding elements.
Wesentliches Element dieser Leitung ist der gleitfähig beschichtete, elastisch komprimierbare Kern, der zugstabil und stauchstabil ausgeführt ist. Durch diesen Kern ist erreicht, daß die beispielsweise in einer Schleppkette dauerbewegte Leitung die permanent auftretenden Zug- und Stauchbelastungen ohne Beschädigungen aushält. Solche Zugbelastungen können für eine in einer Schleppkette frei beweglich angeordnete Leitung in der Beschleunigungsphase von bis zu 50 m/sec2 Werte von 15 N/MM2 bis 20 N/mm2 überschreiten. Während der Verzögerungsphase einer derartigen Schleppkette wirken Stauchkräfte auf die Leitung ein, für welche zu den angegebenen Beschleunigungswerten analoge Werte gelten. Außerdem ist die Biegewechselfestigkeit der Leitung durch den Kern auf Dauer sichergestellt. Der Kern bzw. das elastisch komprimierbare Material der Schicht aus Isoliermaterial desselben füllt die inneren Zwickel zwischen den Verseilelementen vollständig aus, wobei die Verseilelemente in dasselbe eingedrückt werden und in entsprechenden Dellen des Isoliermaterials liegen. Das ergibt eine stabile Führung der Verseilelemente und einen kompakten Aufbau der Leitung. Da die Verseilelemente außerdem wegen der Gleitschicht des Kerns leicht in axialer Richtung auf demselben gleiten können, kann eine mechanische Beschädigung derselben auch nach vielen Biegezyklen mit hoher Sicherheit ausgeschlossen werden.An essential element of this line is the lubricious coated, elastically compressible core, which is designed to be resistant to tension and resistant to compression. Through this core it is achieved that the durably moved, for example, in a drag chain line withstands the permanently occurring tensile and compression loads without damage. Such tensile loads can exceed values of 15 N / MM 2 to 20 N / mm 2 in the acceleration phase of up to 50 m / sec 2 for a cable which is freely movably arranged in a drag chain. During the deceleration phase of such a drag chain compression forces act on the line, for which to the specified Acceleration values analogue values apply. In addition, the bending fatigue strength of the line is ensured by the core in the long term. The core or the elastically compressible material of the layer of insulating material thereof completely fills the inner gussets between the stranding elements, wherein the stranding elements are pressed into the same and lie in corresponding dimples of the insulating material. This results in a stable guidance of the stranding and a compact construction of the line. In addition, since the stranding members are easy to slide on the same in the axial direction because of the sliding layer of the core, mechanical damage thereof can be excluded even after many bending cycles with high safety.
