Description

Unter einer Drehkranzlagerung wird eine Lagerung zweier Teile mittels um ihre mathematische Achse gegeneinander drehbarer Ringe ohne Verivendung eines mittleren Drehzapfens verstanden. Derartige Drehkranzlagerungen werden beispielsweise für die Befestigung einer Lenkachse an einem Fahrzeug und für die Lagerung des drehbaren Teiles eines Drehkranes benutzt. Man hat für Drehkranzlagerungen bereits Anordnungen benutzt, die aus zwei oder drei Ringen bestehen, sogenannte zwei- bzw. dreiteilige Drehkränze; man hat auch schon Drehkränze mit zwei Ringen von Kugeln benutzt, die in axialer Richtung hintereinander in zwei zueinander parallelen Ebenen liegen, sogenannte zweireihige Drehkränze.Under a slewing ring bearing, two parts are supported by means of Rings which can be rotated against each other around their mathematical axis without using a middle pivot understood. Such slewing ring bearings are for example for attaching a steering axle to a vehicle and for mounting the rotatable one Used part of a slewing crane. There are already arrangements for slewing ring bearings used, which consist of two or three rings, so-called two- or three-part Slewing rings; slewing rings with two rings of balls have also been used, the lie one behind the other in the axial direction in two mutually parallel planes, so-called double-row slewing rings.

Die Erfindung betrifft eine Verbesserung von dreiteiligen, zweiteiligen Drehkranzverbindungen, insbesondere von Kugeldrehverbindungen von besonders großem Durchmesser, sehr großer axialer Belastung und gleichzeitig auftretender radialer Belastung. Bei den bekannten Drehkranzverbindungen liegen die beiden Kugelreihen zwischen Ober-und Unterring Ober- und unterhalb einer radialen Schulter eines Zwisrihenringes, wobei Ober- und Unterring satt aufeinanderliegen und mittels Schrauben miteinander verbunden sind: Für Kugeldrehverbindungen großen Durchmessers, bei denen eine Lagerung großer .Genauigkeit gefordert wird, insbesondere für eine möglichst spielfreie Lagerung, haben sich diese bekannten Lagerungen nicht als ausreichend erwiesen.The invention relates to an improvement on three-part, two-part Slewing ring connections, especially of ball slewing rings of particularly large size Diameter, very large axial load and radial load that occurs at the same time Load. In the known slewing ring connections, the two rows of balls are located between the upper and lower ring above and below a radial shoulder of a Zwisrihenringes, whereby the upper and lower ring lie snugly on top of one another and are connected to one another by means of screws are connected: For ball slewing rings with large diameters where there is a bearing great accuracy is required, in particular for a bearing that is as free from play as possible, these known bearings have proven to be insufficient.

Um diese Lagerungen für die genannten Zwecke verwenden zu können, . schlägt die Erfindung vor, Ober- und Unterring ineinander zu zentrieren und die beiden Ringe nicht satt aufeinanderliegend miteinander zu verbinden, sondern sie unter Belassung von Luft zwischen den beiden Anlageflächen unter Federspannung zusammenzuhalten.In order to be able to use these bearings for the purposes mentioned, . the invention proposes to center the upper and lower ring in each other and the not enough to join the two rings on top of each other, but rather they to hold together under spring tension while leaving air between the two contact surfaces.

Die Anordnung eignet sich für Drehaggregate verschiedenster Art, z. B. für Maschinen, Förderanlagen u. dgl., insbesondere für den Drehkranz von um eine senkrechte Achse drehbaren Hebezügen, z. B. Drehkranen.The arrangement is suitable for rotary units of various types, e.g. B. for machines, conveyors and the like, in particular for the slewing ring of around one vertical axis rotatable hoists, z. B. slewing cranes.

Zur Erläuterung der Erfindung sei als Beispiel die Lagerung einer schweren Scheibe mittels einer dreiteiligen, zweireihigen Kugeldrehverbindung an Hand der Schnittzeichnung beschrieben.To explain the invention, the storage of a heavy disc by means of a three-part, double-row rotating ball joint Hand outlined the sectional drawing.

i ist die Scheibe; 2 ist der Oberring; 3 ist der Unterring; 4 ist der Zwischenring, der mit einem Zahnkranz 5 versehen ist. Der Innenring besitzt eine Schulter 6. Oberhalb und unterhalb derselben sind die beiden Reihen von Lagerkugeln 7 und 8 angeordnet. Die Laufbahnen beider Kugelreihen, die sie mit dem Unterring 3 und dem Oberring 2 bilden, sind schräg geteilt. Oberring 2 und Unterring 3 liegen jedoch nicht satt aufeinander, sondern sie stehen in einem gewissen Abstand s voneinander, wenn ihre Laufbahnen, an den Kugeln 7 bzw. 8 anliegen. Die Verbindung von Ober- und Unterring erfolgt über Schrauben io, auf deren Bolzen federnde Elemente i i in Form von Tellerfedern angeordnet sind, so daß Oberring und Unterring ständig mit Vorspannung an den Kugeln 7 und 8 anliegen, die ihrerseits an dem Bund 6 des inneren Zahnringes fest anliegen.i is the disk; 2 is the top ring; 3 is the sub-ring; 4 is the intermediate ring, which is provided with a ring gear 5. The inner ring has a shoulder 6. Above and below it are the two rows of bearing balls 7 and 8 arranged. The raceways of both rows of balls that they connect to the lower ring 3 and the top ring 2 are divided obliquely. Upper ring 2 and lower ring 3 are located but not full of each other, but they are at a certain distance s from each other, when their raceways are in contact with the balls 7 and 8, respectively. The connection of upper and lower ring takes place via screws io, on the bolts of which resilient elements i i are arranged in the form of disc springs, so that the upper ring and lower ring are constantly with bias on the balls 7 and 8, which in turn on the collar 6 of the the inner toothed ring.
