Abstract

In order to produce guiding rollers for conveyor tracks, an elastic clamping element is inserted between the tube and shaft. The torque to be transmitted, which is produced by the transported material, is absorbed by this clamping element. Pressing of the clamping element itself is performed via an elastic disc made of rubber or plastic material and steel discs which compress the elastic material via screws. Distancing sleeves limit and distribute the pressure centrally against the shaft and tube.

Description

Spannelement für RohreClamping element for pipes

Die Erfindung betrifft ein Spannelement insbesondere für Rohre nach dem Oberbegriff des Anspruch 1.The invention relates to a clamping element in particular for pipes according to the preamble of claim 1.

Mit diesem Spannelement soll dem Hersteller von Rollenbahnen die Möglichkeit gegeben werden, ohne großen Aufwand von Bearbeitungsmaschinen mit ganz normalen handelsüblichen Wellen und Rohre unbearbeitet, Rollengänge für die Fördertechnik herzustellen.With this tensioning element, the manufacturer of roller conveyors should be able to can be given without great effort by processing machines with completely normal Commercially available shafts and tubes unprocessed, roller conveyors for conveyor technology to manufacture.

Nach dem derzeitigen Stand der Technik werden solche Förderrollen hergestellt, indem beiderseitig Scheiben mit Aufnahmebolzen eingepresst werden.According to the current state of the art, such conveyor rollers manufactured by pressing disks with locating bolts on both sides.

Diese an sich bekannte Herstellungsweise erfordert jedoch einen ganz erheblichen Arbeitsaufwand. Der Innendurchmesser des Rohres muß zunächst bearbeitet werden. Dann wird die Scheibe eingepresst oder lose eingelegt und verschweißt. Sinngemäß gilt dies auch für den Aufnahmezapfen.However, this known manufacturing method requires a lot considerable amount of work. The inside diameter of the pipe must first be machined will. Then the pane is pressed in or loosely inserted and welded. Analogous this also applies to the mounting pin.

Damit beide Zapfen zentrisch zueinander laufen, müssen diese ebenfalls bearbeitet werden.So that both pins run centrically to each other, they must also to be edited.

Es sind auch sogenannte Konus-Spanneleniente als Verbindungselemente von Welle und Bohrung bekannt, die jedoch für diesen Anwendungsbereich nicht in Frage kommen, weil sie genaue Toleranzen und somit Bearbeitung voraussetzen.There are also so-called cone clamping elements as connecting elements known from shaft and bore, but not in this application area Questions come up because they require precise tolerances and thus machining.

Der Erfindung liegt die Aufgabe zugrunde ein Spannelement zu entwickeln, sodaß keine Bearbeitungen (außer absägen des Rohres auf Länge) erforderlich sind und genormte Rohre und Wellen Verwendung finden können.The invention is based on the object of developing a clamping element, so that no processing (except sawing off the pipe to length) is required and standardized tubes and shafts can be used.

Diese Aufgabe wird durch die kennzeichnenden Merkmale nach Anspruch 1-4 gelöst, wobei das elastische Material zwischen den Stahl scheiben große Herstellungstoleranzen von Rohr und Welle überbrücken kann.This object is achieved by the characterizing features of the claim 1-4 solved, with the elastic material between the steel discs large manufacturing tolerances by tube and shaft can bridge.

Die mit der Erfindung erzielten Vorteile liegen insbesondere an der Einsparung großer Fertigungszeiten und keine teuren Investitionen von Maschinen.The advantages achieved by the invention are in particular due to the Saving of long production times and no expensive investments in machines.

Das Spannelement spannt und zentriert unabhängig von jeder Rohrlänge, sodaß auch Zentrierarbeiten auf langen Drehbänken oder Pressen nicht erforderlich sind.The clamping element clamps and centers independently of each pipe length, so that centering work on long lathes or presses is not necessary are.

Ein Ausführungsbeispiel zeigt in Fig. 1 die herkömmliche Art und Weise der Herstellung von Laufrollen dar.An embodiment is shown in Fig. 1 in the conventional manner the manufacture of rollers.

Pos. 1 zeigt das Rohr Pos. 2 Scheibe mit Bohrung Pos. 3 Aufnahmebolzen für Lagerung Pos. 2 stellt das Spannelement nach Anspruch 1 dar Pos. 1 Welle Pos. 2 Schrauben nach DIN 912 Pos. 3 Distanzbuchsen Pos. 4 Stahlblech mit Durchgangsbohrungen Pos. 5 Stahlblech mit Gewinde.Pos. 1 shows the tube, Pos. 2, washer with a hole, Pos. 3, locating pin for storage pos. 2 represents the clamping element according to claim 1 pos. 1 shaft pos. 2 screws according to DIN 912 pos. 3 spacer bushes pos. 4 sheet steel with through holes Item 5 sheet steel with thread.

Claims (4)

1) Spannelement insbesondere für Rohre dadurch gekennzeichnet, daß zwischen zwei Scheiben ein elastisches Material wie Gummi, Plastik oder ähnliches angeordnet ist das beim zusammenpressen der Scheiben dieses Material nach außen bzw. nach innen gedrückt wird.1) Clamping element, especially for pipes, characterized in that an elastic material such as rubber, plastic or the like between two panes is arranged that when the discs are pressed together, this material is directed outwards or is pressed inwards. und somit eine Verbindung von Aufnahmewelle und Rohr herstellt. and thus establishes a connection between the take-up shaft and the tube. 2) Spannelement nach Anspruch 1 dadurch gekennzeichnet, daß der Pressdruck bei beiden Scheiben durch Distanzringe verkleinert oder vergrößert werden kann.2) Clamping element according to claim 1, characterized in that the pressing pressure both discs can be reduced or enlarged using spacer rings. 3) Spannelement nach Anspruch 1 dadurch gekennzeichnet, daß durch eine Vielzahl von Distanzringe der Außen- bzw. Innendruck gleichmäßig verteilt wird.3) clamping element according to claim 1, characterized in that by a large number of spacer rings that distribute the external and internal pressure evenly. 4) Spannelement nach Anspruch 1 dadurch gekennzeichnet, daß die Vielzahl von Distanzringe auch durch einen gesamten Ring ersetzt werden können.4) Clamping element according to claim 1, characterized in that the plurality of spacer rings can also be replaced by an entire ring.
