Description
Die Erfindung bezieht sich auf ein Kufenschreitwerk mit einer in einem Kulissenrahmen bewegten Exzenterscheibe. Bei den bekannten Schreitwerken dieser Art gleitet zum größten Teil die Exzenterscheibe in dem Kulissenrahmen, zum kleineren Teil rollt sie darauf ab. Daraus ergibt sich eine starke Abnutzung der in der Hauptsache aufeinandergleitenden und dadurch reibenden Flächen bei gleichzeitig verhältnismäßig hohem Kraftaufwand.The invention relates to a skid treadmill with one in one Link frame moving eccentric disc. In the case of the well-known walking works of this Art slides for the most part the eccentric disk in the backdrop frame, to the smaller one Part she rolls off on it. This results in heavy wear and tear on the main surfaces sliding on each other and thereby rubbing at the same time relatively high effort.
Durch die Erfindung wird dieser Nachteil dadurch vermieden, daß die Exzenterscheibe unter Zwischenschaltung von mindestens einem Wälzlager od. dgl. von einem im Kulissenrahmen abrollenden Laufring umgeben ist. An Stelle der größtenteils gleitenden Reibung bei den bekannten Ausführungen tritt nunmehr beim Erfindungsgegenstand eine rollende Reibung.The invention avoids this disadvantage in that the Eccentric disk with the interposition of at least one roller bearing or the like. is surrounded by a rolling ring in the gate frame. In place of mostly Sliding friction in the known designs now occurs in the subject matter of the invention a rolling friction.
In der Zeichnung ist die Erfindung beispielsweise dargestellt. Es zeigt Fig. I die Seitenansicht eines Schreitwerkes und Fig. 2 einen Schnitt nach Linie II-II der Fig. I. In dem Gehäuse I des mit Schreitkufen 2 ausgerüsteten Gerätes, beispielsweise eines Baggers, ist die Welle 3 gelagert. Die Welle 3 ist weiterhin durch Rundkeile 4 in der Exzenterscheibe 5 befestigt. Die Exzenterscheibe 5 ist auf Wälzlagern 6, in dem gezeigten Beispiel auf Rollenlagern, in einem Laufring 7 abgestützt. In einem ovalen Kulissenrahmen 8, an dem Stäbe 9 die senkrechte Kulisse Io tragen, rollt der Laufring 7. Der Transportzapfen II ist in üblicher Weise in der Kulisse Io geführt.In the drawing, the invention is shown as an example. It FIG. I shows the side view of a walking mechanism and FIG. 2 shows a section according to Line II-II of Fig. I. In the housing I of the device equipped with step runners 2, for example an excavator, the shaft 3 is supported. Wave 3 is still there fastened in the eccentric disk 5 by round wedges 4. The eccentric 5 is on roller bearings 6, in the example shown on roller bearings, in a race 7 supported. In an oval backdrop frame 8 on which rods 9 the vertical backdrop Wear Io, the raceway 7 rolls. The transport pin II is in the usual way the backdrop of Io.
