Description
Die Erfindung· betrifft ein Krandrehwerk, bei dem der Motor und das Getriebe zu einem Block zusammengefaßt sind, und besteht darin, daß der Block um. eine zum Zahneingriff paraJlele Achse federnd drehbar an der Kranplattform angeordnet ist.The invention relates to a crane slewing gear, in which the engine and the gearbox are combined into one block, and consists in that the block around. an axle that is parallel to the meshing of the teeth is resiliently rotatable on the crane platform is arranged.
Es wird hierdurch in einfachster Weise 'eine Abfederung des Antriebs erreicht, da sich der Block bei plötzlichem Anfahren und Abbremsen entgegen der Abfederung drehen und dadurch die im Getriebe auftretenden Stoßbeanspruchungen dämpfen kann.It is thereby achieved in the simplest way 'a cushioning of the drive, since the When suddenly starting and braking, turn the block against the cushioning and thereby can dampen the shock loads occurring in the gearbox.
Sofern bei den bisher bekanntgewordenen Drehwerksantrieben, für eine Abfederung Sorge getragen war, erfolgte diese durch federnde Befestigung des auf dem festen Unterbau des Krans gelagerten Drehkranzes, also durch eine verhältnismäßig teuere Bauweise.Provided that the slewing drives that have become known so far, concern for a cushioning was carried, this was done by resilient fastening of the on the solid base of the Crane mounted slewing ring, so by a relatively expensive construction.
Die Erfindung bietet demgegenüber den Vorteil der Einfachheit sowie die Möglichkeit, die Abfederung im Betriebe besser beobachten und warten zu können.In contrast, the invention offers the advantage of simplicity and the possibility of to be able to better observe and maintain the cushioning in the company.
Zweckmäßig· wird die Anordnung derart getroffen, daß die Drehachse des Blockes mit der Achse des in den Zahnkranz eingreifenden Ritzels zusammenfällt.The arrangement is expediently made in such a way that the axis of rotation of the block coincides with the axis of the pinion meshing with the ring gear.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. In dieser zeigtAn embodiment of the invention is illustrated in the drawing. In this shows
