KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind biegsame Wellen bekannt, welche aus Gelenkketten bestehen, über welche ein biegsamer Schlauch gezogen ist. Die Verwendbarkeit dieser biegsamen Wellen ist eine sehr beschränkte, da infolge von Knoten- oder Kinkenbildung die zu größeren Kraftübertragungen notwendige Widerstandsfähigkeit fehlt.There are flexible shafts known, which consist of link chains, over which a flexible hose is pulled. The utility of these flexible shafts is one very limited, since the formation of knots or kinks leads to greater power transmissions the necessary resilience is lacking.

Die Welle nach dieser Erfindung besteht aus einer Kreuzgelenkkette, welche von einem derart profilierten und elastischen Schlauch umgeben ist, daß die Biegung der Welle begrenzt wird, so daß die Bildung von Knoten (Kinken) ausgeschlossen ist.The shaft according to this invention consists of a universal joint chain, which of a so profiled and elastic hose is surrounded that limits the bending of the shaft so that the formation of knots (kinks) is excluded.

Diese biegsame Welle bietet eine große Widerstandsfähigkeit, weshalb sie zu großen Kraftübertragungen geeignet ist; auch kann sie in jeder Richtung gedreht werden.This flexible shaft offers great resistance, which is why it is too large Power transmissions is suitable; it can also be rotated in any direction.

Die beiliegende Zeichnung stellt verschiedene Ausfuhrungsformen der Welle dar.The accompanying drawing shows various designs of the shaft.

Bei dem ersten Ausführungsbeispiel (Fig. 1) ist jedes Glied b mit Nut und Feder bezw. Zapfen versehen. Feder (oder Zapfen) α jedes Gliedes b besitzt einen Kopf c, welcher in die Nut (oder Aussparung) d des nächsten Gliedes faßt,, wobei diese Nut oder Aussparung d senkrecht zur Feder α steht und so geformt ist, daß das Glied b um den Kopf c beweglich ist.In the first embodiment (Fig. 1), each member b with tongue and groove BEZW. Provided tenon. The tongue (or pin) α of each link b has a head c which engages in the groove (or recess) d of the next link, this groove or recess d being perpendicular to the tongue α and being shaped so that the link b around the head c is movable.

Bei einer anderen Ausführungsform (Fig. 2) sind die Glieder b an beiden Enden mit Nuten d versehen, die zueinander rechtwinklig versetzt sind.In another embodiment (FIG. 2), the links b are provided at both ends with grooves d which are offset at right angles to one another.

An Stelle der Federn oder Zapfen nach Fig. ι kommen hier Verbindungsstücke a mit zwei Enden c in Anwendung. Diese Verbindungsstücke fassen in die Nuten zweier benachbarten Glieder.Instead of the springs or pins according to FIG. 1, connecting pieces a with two ends c are used here. These connecting pieces engage in the grooves of two adjacent links.

Fig. 3 und 4 zeigen zwei andere Ausführungsformen, welche sich von den beiden erst beschriebenen im wesentlichen nur dadurch unterscheiden, daß an Stelle der Köpfe c Gelenkstifte e zum Auseinanderhalten der Glieder bezw. der Glieder und Zwischenstücke benutzt sind.3 and 4 show two other embodiments which differ from the two first described essentially only in that instead of the heads c hinge pins e for holding apart the members respectively. the links and spacers are used.

Fig. 5 ist ein Beispiel für die Profilierung des elastischen Schlauches zum Teil in Ansicht, zum Teil im Querschnitt.Fig. 5 is an example of the profiling of the elastic hose partially in view, partly in cross section.

Claims (1)

Patent-Anspruch: ^0 Patent claim: ^ 0 Biegsame Welle, bestehend aus einer Kreuzgelenkkette, die von einem aus Formblech gewundenen, biegsamen Schlauche umgeben ist, dadurch gekennzeichnet, daß durch die Querschnittsform des zur Bildung des Schlauches verwendeten Fonnblechs die Biegsamkeit der Welle begrenzt wird, zum Zwecke, die Mittel für Kraftübertragung und für Biegungsbegrenzung zur Vermeidung der Knoten- oder Kinkenbildung vollständig voneinander zu trennen.Flexible shaft, consisting of a universal joint chain, which is supported by a shaped sheet metal coiled, flexible tubing is surrounded, characterized in that by the cross-sectional shape of the to form of the hose used Fonnblechs the flexibility of the shaft is limited, for the purpose of the means for power transmission and for bending limitation to avoid knot or kink formation completely separated from each other.
