Description

Das Hauptpatent betrifft einen Drehkranz, z. B. für den Oberwagen von Kranfahrzeugen, der aus einem Radkörper mit Profilkranz für die Tragrolle besteht. Die weitere Ausgestaltung dieser Anordnung besteht darin, daß einige der Tragrollen gegen den oberen und andere gegen den unteren Flansch-Innenrand des Profilkranzes anliegen. Diese Anordnung wird dadurch erreicht, daß der Schaft der Tragrollenhalter abgesetzt ist und über Abstandsstücke, die zwischen dem Absatz und dem Oberwagen eingefügt werden, gegen den Oberwagen angezogen wird.The main patent relates to a slewing ring, e.g. B. for the superstructure of crane vehicles, which consists of a wheel center with a profile rim for the idler roller. The further embodiment of this arrangement is that some of the support rollers against the upper and other against the lower flange inner edge of the profile rim issue. This arrangement is achieved in that the shaft of the roller holder is separated and about spacers between the paragraph and the upper structure inserted against the upper structure is attracted.

Diese Anordnung gewährleistet eine spielfreie und nachstellbare Führung der Tragrollen im Drehkranz un-d@ damit des Oberwagens am Unterwagen.This arrangement ensures a backlash-free and adjustable guide the idlers in the turntable and thus the superstructure on the undercarriage.

In der Zeichnung ist der Gegenstand der Erfindung in einem Ausführungsbeispiel im Auf- und Grundriß veranschaulicht.In the drawing, the subject of the invention is in one embodiment illustrated in elevation and plan.

Abb. i zeigt eine Seitenansicht der Laufrolle im Schnitt durch den Drehkranz; Abb. 2 zeigt eine Draufsicht auf die Rollenanordnung mit Drehkranz im Schnitt.Fig. I shows a side view of the roller in section through the Slewing ring; Fig. 2 shows a top view of the roller assembly with the turntable in Cut.

Im Profilkranz des Radkörpers cc laufen die horizontal gelagerten Rollen d, die an Dornen c drehbeweglich angebracht sind. Die Dorne c werden am Oberwagenrahmen b, z. B. mittels Muttern f; gegebenenfalls drehbar und höhenverstellbar befestigt. dl zeigt eine Rolle in herausgeschwenkter Stellung; Einige der Rollen d liegen dabei gegen den oberen Flanschinnenrand des Profilkranzes a an, andere gegen den unteren. Die Lage der Tragrollen d im Profilkranz kann durch die höhenverstellbaren Dorne c beliebig geändert werden.In the profile rim of the wheel body cc run the horizontally mounted rollers d, which are rotatably attached to thorns c. The mandrels c are on the upper carriage frame b, z. B. by means of nuts f; optionally rotatable and adjustable in height. dl shows a role in the pivoted out position; Some of the rollers d rest against the upper flange inner edge of the profile rim a, others against the lower one. The position of the support rollers d in the profile ring can be changed as required using the height-adjustable mandrels c.
