Description

Schutzschlauch für biegsame Wellen und Druck-Zug-Kabel mit einer Drahteinlage aus parallel zur Schlauchachse verlaufenden Drähten Die Erfindung betrifft einen Schutzschlauch für biegsame Wellen und Druck-Zug-Kabel mit einer Drahteinlage aus parallel zur Schlauchachse verlaufenden Drähten.Protective hose for flexible shafts and push-pull cables with a wire insert made of wires running parallel to the tube axis. The invention relates to a Protective hose for flexible shafts and push-pull cables with a wire insert wires running parallel to the hose axis.

Bei den bekannten Schutzschläuchen dieser Art sind die Drähte der Drahteinlage gerade und versteifen den Schutzschlauch derart stark, daß eine Verlegung des Schutzschlauches in Bögen nur sehr großen Krümmungshalbmessers möglich ist. Um diesen Nachteil zu beseitigen, sind gemäß der Erfindung die Drähte der Drahteinlage gewellt. Dadurch wird eine Verlegung des Schutzschlauches im Boaen mit verhältnismäßig kleinem Krümmungsradius ermöglicht, indem auf der Innenseite des Bogens die Wellen zusammengedrückt und auf der Außenseite gestreckt werden. Die Zug- und Druckfestigkeit des Schutzschlauches in axialer Richtung bleibt weitgehend erhalten.In the known protective hoses of this type, the wires are the Wire insert straight and stiffen the protective hose so much that it is laid of the protective hose in bends is only possible with a very large radius of curvature. In order to eliminate this disadvantage, according to the invention, the wires are the wire insert wavy. As a result, laying the protective hose in the boaen is proportionate Small radius of curvature made possible by placing the waves on the inside of the arch squeezed and stretched on the outside. The tensile and compressive strength of the protective hose in the axial direction is largely retained.

Die Drähte sind vorteilhaft in Kunststoff eingebettet.The wires are advantageously embedded in plastic.

In der Zeichnung ist der Gegenstand der Erfindung beispielsweise und schematisch dargestellt. Es zeigt Fi g. 1 eine Seitenansicht eines Schlauchstückes mit einem zerlegten Ende, F i g. 2 einen Schnitt durch den Schutzschlauch gemäß F i g. 1. In the drawing, the subject matter of the invention is shown schematically and by way of example. It shows Fi g. 1 is a side view of a piece of tubing with a disassembled end, FIG. 2 shows a section through the protective tube according to FIG. 1.

Der Schutzschlauch besteht aus einem inneren Führungsschlauch 1 aus Kunststoff oder aus Metalldrähten. Im letzteren Falle kann der Schutzschlauch noch eine Auskleidung aus Kunststoff aufweisen, um die Reibung gegenüber der biegsamen Welle oder dem Druck-Zug-Kabel herabzusetzen.The protective hose consists of an inner guide hose 1 made of plastic or metal wires. In the latter case, the protective hose can also have a plastic lining in order to reduce the friction with respect to the flexible shaft or the push-pull cable.

Um den Führungsschlauch 1 ist eine Lage von Drähten 2 angeordnet, die parallel zur Achse des Schutzschlauches verlaufen und gewellt sind. Den Außenmantel 3 des Schutzschlauches bildet ein darüber gespritzter Kunststoffmantel, in den die Drähte 2 eingebettet sind. Um die Lage der Drähte 2 herum kann auch eine Metalldrahtumflechtung vorgesehen sein.A layer of wires 2, which run parallel to the axis of the protective tube and are corrugated, is arranged around the guide tube 1. The outer jacket 3 of the protective tube is formed by a plastic jacket injected over it, in which the wires 2 are embedded. A metal wire braiding can also be provided around the position of the wires 2.

Durch die parallel zur Schlauchachse verlegten Drähte 2 wird der Schutzschlauch weitgehend in axialer Richtung zug- und druckfest. Die Wellung der Drähte 2 erleichtert jedoch die Verlegung des Schutzschlauches im Bogen, da sich die Drähte auf der Innenseite des Bogens zusammendrücken und auf der Außenseite strecken lassen.The protective hose is created by the wires 2 laid parallel to the hose axis largely resistant to tension and compression in the axial direction. The corrugation of the wires 2 facilitates However, the laying of the protective hose in a bend, as the wires are on the inside of the arch and let it stretch on the outside.
