Abstract
Description
Die Erfindung betrifft eine Spannhülse zur Befestigung auf einer zylindrischen Welle oder Achse gemäß den Merkmalen des Anspruches 1.The The invention relates to a clamping sleeve for mounting on a cylindrical shaft or axle according to the features of claim 1.
Vorrichtungen für Welle-Nabe-Verbindungen, wie Klemmnaben, Schrumpfscheiben und dergleichen sind bereits seit längerer Zeit bekannt. Dabei wird das Prinzip der Keilwirkung und elastischen Verformung von keilförmigen Spannelementen benutzt.devices for shaft-hub connections, like clamping hubs, shrink discs and the like are already longer Time known. Here, the principle of wedge action and elastic deformation of wedge-shaped Used clamping elements.

Die US 2005/0089364 A1 zeigt eine Spannhülse, die mittels einer Gewindemutter verspannt wird.The US 2005/0089364 A1 shows a clamping sleeve, which by means of a threaded nut is strained.
Der Erfindung liegt die Aufgabe zugrunde, eine Spannhülse zur Befestigung auf einer zylindrischen Welle oder Achse zu schaffen, mit der der Zeitaufwand für das Herstellen und Lösen der Klemmverbindung wesentlich verringert wird.Of the Invention is based on the object, a clamping sleeve for Attachment to a cylindrical shaft or axle to provide with the time required for the manufacture and release the clamping connection is substantially reduced.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.The The object is achieved by the Characteristics of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass der Zeitaufwand für das Herstellen und Lösen der Klemmverbindung wesentlich verringert wird, da das aufwendige kleinschrittige Einschrauben aller Umfangs-Spannschrauben entfällt. Dies erweist sich insbesondere beim Einsatz der Klemmverbindung an Rollenträgern bei der Tragarmverstellung als vorteilhaft, weil hier sehr hohe Spannkräfte erreicht werden. Gleichzeitig erfolgt das Spannen und Entspannen in nur einem Arbeitsgang manuell oder automatisiert mithilfe einer feststellbaren Spannmutter.The particular advantages of the invention are that the time required for that Manufacture and release the clamping connection is substantially reduced, since the expensive Small-step screwing in all circumferential clamping screws is eliminated. This proves especially when using the clamp connection to roll carriers the Tragarmverstellung advantageous because achieved here very high clamping forces become. At the same time, the tensioning and relaxing takes place in just one Operation manual or automated using a detectable Clamping nut.
Beispielsweise wird bei einer Produktionsumstellung an einem Rollenwechsler auf eine neue Rollenbreite durch Verschiebung der Tragarme auf einer Verschiebeachse die neue Rollenbreite grob eingestellt. Beim Ein- und Ausachsen der Materialrollen werden die Tragarme mit einem Feineinstellmechanismus axial bewegt. Die Spannvorrichtung an der Verschiebeachse, muss dabei nicht nur Axialkräfte von Tragarmen und Rollengewicht aufnehmen, sondern auch noch die notwendige Vorschubkraft zum Einspannen der Hülse der Materialrolle in Spannkonen. Da Tragarme und Materialrollen ein sehr großes Gewicht haben, und die Tragarme auch beim Abspulen der Materialrolle mit enormen Kräften belastet werden, sind hier sehr hohe Spannkräfte von ca. 40 kN erforderlich, um die Betriebssicherheit zu gewährleisten.For example becomes a reel changer during a production changeover a new roll width by displacement of the support arms on one Shift axis coarsely set the new roll width. When entering and Ausachsen the rolls of material, the support arms with a fine adjustment mechanism moved axially. The clamping device on the displacement axis, must not only axial forces of support arms and reel weight record, but also the necessary feed force for clamping the sleeve of the roll of material in clamping cones. Since support arms and rolls of material have a very large weight, and the Support arms loaded with enormous forces even when unwinding the roll of material very high clamping forces of approx. 40 kN are required here, to ensure operational safety.
Erfindungsgemäß werden ein Schrumpfring und ein Spannring, wie sie aus dem Stand der Technik prinzipiell bekannt sind, so miteinander kombiniert, dass sie in montiertem Zustand an ihrer Außenseite einen Abschnitt mit einem Außengewinde aufweisen. Werden Schrumpfring und Spannring in axialer Richtung aufeinander zu bewegt, so bewirken sich berührende Konusflächen von Schrumpfring und Spannring durch eine Keilwirkung eine elastische Verformung des Schrumpfringes in radialer Richtung.According to the invention a shrink ring and a clamping ring, as known from the prior art are known in principle, so combined that they are in mounted state on its outside a section with an external thread exhibit. Be shrink ring and clamping ring in the axial direction moving towards each other, touching conical surfaces of Shrink ring and clamping ring by a wedge effect an elastic deformation of the shrink ring in the radial direction.
Eine Spannmutter besitzt ein Innengewinde, welches zumindest abschnittsweise mit dem Außengewindeabschnitt auf dem Schrumpfring und/oder dem Spannring korrespondiert. Eine Drehung der Spannmutter bewirkt eine gegenläufige axiale Bewegung von Schrumpfring und Spannring. Je nach Drehrichtung der außen liegenden Spannmutter erfolgt dadurch das Spannen bzw. Entspannen des Schrumpfrings.A Clamping nut has an internal thread, which at least in sections with the male threaded portion corresponds to the shrink ring and / or the clamping ring. A Rotation of the clamping nut causes an opposite axial movement of the shrink ring and clamping ring. Depending on the direction of rotation of the outer clamping nut takes place thereby tightening or relaxing the shrink ring.
Die so hergestellte Klemmverbindung kann noch durch eine Sicherung gegen ungewolltes Zurückdrehen der Spannmutter gesichert werden.The so produced clamp connection can still by a backup against unintentional turning back be secured the clamping nut.
Eine abgewandelte Ausführungsform zeichnet sich dadurch aus, dass nur auf einem der beiden Elemente Schrumpfring und Spannring ein Außengewinde angebracht ist. Die Spannmutter greift an dem Element ohne Außengewinde in eine einfache Nut ein. Dies ermöglicht geringere Kosten bei der Herstellung der Spannhülse.A modified embodiment is characterized in that only on one of the two elements Shrink ring and clamping ring an external thread is attached. The clamping nut engages the element without external thread in a simple Groove. this makes possible lower costs in the production of the clamping sleeve.
