Description
Drehkranz, insbesondere von Iranfahrzeugen. Die Erfindung bezieht sich auf einen Drehkranz am schwenkbaren Oberwagen ins besondere von Kranfahrzeugen, welcher Dreh kranz :ein Rad mit Profilkranz für die Trag s rollen aufweist.
Gemäss der Erfindung sind die Tragrollen auf Achsstücken gelagert, die ihrerseits um ausserhalb der äussern, Rollenstirnfläche be- findliche, in: einem Winkel zur Rollenachse s angeordnete geometrische Achsen drehbar sind. Die Erfindung schafft Mittel, um ein leichtes Abheben .des Oberwagens von :dem Unterwagen zu ermöglichen.
Zu diesem Zweck sind die Tragrollen zum Beispiel auf winkelförmigen Achsstücken gelagert, :die am Oberwagen :drehbar angebracht sind.
In der Zeichnung ist der Gegenstand der Erfindung in einer Seitenansicht im Schnitt, Fig. 1, und in Draufsicht dazu, Fig. 2, @dar- gestellt.
Um; eine .gleichmässig ,gute Führung des Oberwagens bei jeder Neigung im Gelände und auch .bei jeder wechselnden Belastung zu erzielen, werden :die Laufrollen d in einem im Querschnitt U-förmig :ausgebildeten Dreh kranz geführt.
Zur leichteren Montage und Demontage dess Oberwagens gegenüber dem Unterwagen sind diese Rollen auf Winkel- förmig ausgebildeten Achsstücken c angeord net, so dfass eie zunäelvet beim Aufsetzen :
des Oberwagens während der Montage die Stel lung d, annehhnen können, um dann in die .ge- zeichnete Stellung d eingeschwenkt zu wer den. Das Festhalten in der Betriebsstellung erfolgt durch Riegel e.
Die Tragrollen d können zur Erzielung einer spielfreien Führung des Oberwagens abwechselnd an :den gegenüberliegenden In nenflanken -dies Rades a laufen und dazu höhenverstellbar sein.
Slewing ring, especially for Iran vehicles. The invention relates to a slewing ring on the swiveling superstructure in particular of crane vehicles, which slewing ring: has a wheel with a profile ring for the supporting s rolls.
According to the invention, the support rollers are mounted on axle pieces, which in turn can be rotated about geometrical axes located outside the outer, roller end face and arranged at an angle to the roller axis s. The invention provides means to enable easy lifting of the upper structure from: the undercarriage.
For this purpose, the support rollers are mounted, for example, on angular axle pieces: which are rotatably attached to the superstructure.
In the drawing, the subject matter of the invention is shown in a sectional side view, FIG. 1, and in a plan view, FIG. 2, @.
Around; To achieve .even, good guidance of the superstructure with every slope in the terrain and also .with every changing load, the rollers d are guided in a turntable with a U-shaped cross-section.
To make it easier to assemble and disassemble the superstructure in relation to the undercarriage, these rollers are arranged on angularly shaped axle pieces c, so that first of all:
of the superstructure can assume position d i during assembly, in order to then be swiveled into position d shown. It is held in the operating position by means of bolts e.
To achieve a backlash-free guidance of the superstructure, the support rollers d can alternately run on: the opposite inner flanks -dies wheel a and be adjustable in height for this purpose.
