Description

Schlauch für biegsame Wellen. Zur Vermeidung von Übelständen bei biegsamen Wellen zum Antrieb von Apparaten, bei denen das Werkzeug in ein Handstück o. dgl. eingespannt ist, ist bereits vorgeschlagen worden, die biegsame Welle mit einem Schlauch aus einem spiralförmig gewundenen Stahldraht zu umgeben, der von einem herumgewickelten Metallband umschlossen wird. Die Anwendung eines derartigen Schlauches hat jiedoch seinerseits den Nachteil des höheren Gewichtes, wodurch die Handhabung des Handstückes erschwert und die praktische Anwendung unmöglich gemacht wird, insbesondere, wenn es sich um feinere Arbeiten handelt, z. B. für zahnärztliche Zwecke oder für Grw.aure o. dgl.Flexible shaft hose. To avoid nuisances with flexible ones Shafts for driving apparatus in which the tool is in a handpiece or the like. is clamped, has already been proposed, the flexible shaft with a Hose made of a helically wound steel wire surrounded by a wrapped around metal tape is enclosed. The use of such a hose However, it has the disadvantage of higher weight, which makes it easy to use of the handpiece is made difficult and practical use is made impossible, in particular, when it comes to finer work, e.g. B. for dental purposes or for Grw.aure or the like

Erfindungsgemäß wird nun die Anwendung der erwähnten Schläuche für die genannten Zwecke dadurch möglich gemacht, daß das den spiralförmig gewundenen Draht umschließende Metallband, gegebenenfalls auch der spiralförmig gewundene Draht selbst, aus Leichtmetall, nicht, wie bisher, aus Eisen oder Stahl hergestellt wird.According to the invention, the application of the hoses mentioned is now for the purposes mentioned made possible by the fact that the spirally wound Metal band enclosing wire, possibly also the spirally wound wire itself, made of light metal, not, as before, made of iron or steel.

Die Zeichnung zeigt eine beispielsweise Ausführungsform der Erfindung, und zwar ist Abb. i eine Ansicht einer biegsamen Welle mit Schlauch, wobei letzterer teilweise unterbrochen dargestellt ist, während Abb.2 einen Längsschnitt durch den Schlauch allein in vergrößertem Maßstab darstellt.The drawing shows an example embodiment of the invention, namely, Fig. i is a view of a flexible shaft with hose, the latter is shown partially interrupted, while Fig.2 is a longitudinal section through the Represents hose alone on an enlarged scale.

Der Schlauch besteht aus dem spiralförmig gewickelten Metalldraht a und dem um diesen herumgewickelten Metallband b, dessen Außenfläche glatt ist, während die Innenfläche d so ausgebildet ist, daß sie sich der Form der Spirale anpaßt. Innerhalb des Schlauches liegt dann die eigentliche biegsame Welle g, die aus einer Drahtspirale besteht und an dit am Ende die Anschlußstücke e und f in bekannter Weise angeschlossen sind. Das Metallband b und gegebenenfalls auch die Drahtspirale a besteht, wie erwähnt, aus Leichtmetall, und zwar verwendet man vorzugsweise Aluminium oder Duralumin hierfür. Ein Vernickeln ist, da diese Metalle nicht rosten, nicht erforderlich.The hose consists of the spirally wound metal wire a and the metal band b wound around it, the outer surface of which is smooth, while the inner surface d is designed to follow the shape of the spiral adapts. Inside the hose then lies the actual flexible shaft g, the consists of a wire spiral and at the end the connectors e and f in are connected in a known manner. The metal band b and possibly also the Wire spiral a consists, as mentioned, of light metal, and is preferably used Aluminum or duralumin therefor. Nickel plating is because these metals do not rust, not mandatory.
