GliederkäfigLink cage
Die Erfindung betrifft einen Gliederkäfig nach dem Oberbegriff des Hauptanspruches.The invention relates to a link cage according to the preamble of the main claim.
Durch die FR 2 076 180 ist ein Gliederkäfig für Rollen bekannt, bei dem kastenförmige Segmente aus Kunststoff über elastische Gelenke miteinander verbunden sind. Die Gelenke sind in die Seitenringe eingearbeitet. Durch eine dem Verwendungszweck angepaßte Gesamtlänge des Gliederkäfigs können verschiedene Anwendungen mit kreisförmigen oder komplex gekrümmten Laufbahnen abgedeckt werden. Der Anwendungsbereich erstreckt sich demnach auch auf Rollengänge mit Tragfunktion oder zur Abstützung von Transmissionen.FR 2 076 180 describes a link cage for rollers in which box-shaped plastic segments are connected to one another via elastic joints. The joints are incorporated into the side rings. By adapting the overall length of the link cage to the intended use, various applications with circular or complex curved tracks can be covered. The area of application therefore also extends to roller conveyors with a load-bearing function or to support transmissions.
Nachteilig ist bei der bekannten Lösung, daß die Gelenke aufeinanderfolgende Segmente in beide Richtungen elastisch abstützen, dadurch auch einseitig nachgeben können und somit eine Schiefstellung der Rollen oder deren Einklemmen in die Tasche des Kastenelementes möglich ist. Eine präzise Führung ist somit nicht immer zu erwarten. Weiterhin hat der bekannte Gliederkäfig mindestens eine unverbundene Stelle, bzw. ist nicht endlos, so daß beim Zusammenbau Vorkehrungen gegen Auseinanderfallen getroffen werden müssen.The disadvantage of the known solution is that the joints elastically support successive segments in both directions, which means they can also give way on one side and thus the rollers can become skewed or jammed in the pocket of the box element. Precise guidance cannot therefore always be expected. Furthermore, the known link cage has at least one unconnected point and is not endless, so that precautions must be taken during assembly to prevent it from falling apart.
Aufgabe der Erfindung ist es, einen Gliederkäfig der eingangs genannten Art zu schaffen, der die Rollen ohne Schiefstellung trennt und bei der Montage nicht auseinanderfällt.The object of the invention is to create a link cage of the type mentioned at the beginning, which separates the rollers without misalignment and does not fall apart during assembly.
Die Aufgabe wird dadurch gelöst, daß die über Gleitflächen aneinandergefügten Einzelsegmente mit einem umlaufenden, geschlossenen Federelement elastisch verbunden und gegen Herausfallen gesichert sind.The task is solved by the fact that the individual segments, which are joined together via sliding surfaces, are elastically connected to a circumferential, closed spring element and are secured against falling out.
Die Segmente sind kastenförmig ausgeführt und bilden eine feste Tasche für Rollen. Die quer zur Laufrichtung verlaufenden Endflächen bilden Fügeflächen zwischen aufeinanderfolgenden Segmenten, die als Gleitflächen ausgebildet sind. Dadurch sind die Segmente untereinander fest abgestützt und können sich nicht schiefstellen. Bei Bedarf können die Gleitflächen auch gekrümmt sein und so der Bewegung der Segmente angepaßt werden. Der gesamte Gliederkäfig, der im eingebauten Zustand endlos ist, ist von einem elastischen Federelement, beispielsweise einer Schraubenfeder, einem Gummiring, etc. zusammengehalten, um den Einbau einfacher zu gestalten.The segments are box-shaped and form a solid pocket for rollers. The end surfaces running perpendicular to the running direction form joining surfaces between successive segments, which are designed as sliding surfaces. This means that the segments are firmly supported against one another and cannot become crooked. If necessary, the sliding surfaces can also be curved and thus adapted to the movement of the segments. The entire link cage, which is endless when installed, is held together by an elastic spring element, for example a coil spring, a rubber ring, etc., to make installation easier.
Diese und weitere Merkmale werden nachfolgend an dem in der Zeichnung dargestellten Beispiel beschrieben.These and other features are described below using the example shown in the drawing.
Es zeigen:Show it:
Figur 1 die Seitenansicht eines Teilgetriebes mit Schubgliederband mitFigure 1 shows the side view of a partial transmission with push belt with
Rollenab Stützung undRoller support and
Figur 2 den Querschnitt eines Käfigsegmentes mit Rolle und Federn.Figure 2 shows the cross-section of a cage segment with roller and springs.
Das in den Figuren dargestellte Keilscheibengetriebe besteht aus zwei gleichgroßen Keilrädern 1, deren Keilscheiben wechselseitig verstellbar sind und somit ein bekanntes Schubgliederband 2 fester Länge stets gespannt halten. Der Rücken des Schubgliederbandes 2 wird durch eine endlose Rollenkette 3 abgestützt, die selbst gegen ein flexibles, jedoch in der Länge festes Stahlband 4 im Außenbereich anläuft. Bei Versteilung der Keilscheiben und damit der Übersetzung passen sich sowohl die Rollenkette 3 als auch das flexible Stahlband 4 der Laufgeometrie des Schubgliederbandes 2 an.The wedge-disk gear shown in the figures consists of two equally sized wedge wheels 1, the wedge disks of which are mutually adjustable and thus always keep a known push-link belt 2 of fixed length taut. The back of the push-link belt 2 is supported by an endless roller chain 3, which itself runs against a flexible, but length-fixed steel belt 4 on the outside. When the wedge disks and thus the gear ratio are adjusted, both the roller chain 3 and the flexible steel belt 4 adapt to the running geometry of the push-link belt 2.
Die Rollen sind in kastenförmige Käfigsegmenten 5 eingesetzt. An den Berührungsflächen untereinander sind Gleitgelenke 6 angeordnet, die einen festen Abstand der Rollen gewährleisten. An den Seitenflächen der Käfigsegmente 5 sind Nuten 7 angeformt, in die je eine vorgespannte Schraubenfeder 8 eingesetzt ist, deren Enden fest verbunden sind, wodurch sich eine endlose, auf Zug beanspruchte Feder 8 ergibt. Auf diese Weise liegen alle Käfigsegmente 5 mit den Flächen ihrer Gleitgelenke 6 aneinander und können nicht herausfallen. Die Feder 8 verhindert weiterhin eine Formierung der Käfigsegmente 5 in Zickzackanordnung.The rollers are inserted into box-shaped cage segments 5. On the contact surfaces between each other, sliding joints 6 are arranged, which ensure a fixed distance between the rollers. Grooves 7 are formed on the side surfaces of the cage segments 5, into each of which a pre-stressed helical spring 8 is inserted, the ends of which are firmly connected, resulting in an endless spring 8 subject to tension. In this way, all cage segments 5 lie against each other with the surfaces of their sliding joints 6 and cannot fall out. The spring 8 also prevents the cage segments 5 from forming a zigzag arrangement.
Der an diesem Beispiel beschriebene Gliederkäfig ist mit den gleichen Vorteilen bei Wälzlagern, Rollengängen, etc. verwendbar.The link cage described in this example can be used with the same advantages for rolling bearings, roller conveyors, etc.
