Description

Die Erfindung betrifft eine Großdrehlagerung zur lösbaren Befestigung des Oberteiles eines Fahrzeugkranes, Baggers oder dgl. Gerätes an dem relativ dazu feststehenden Unterwagen desselben Gerätes, wobei zur Übertragung der Drehbewegung am Oberwagen und am Unterwagen jeweils Laufflächen für Wälzkörper vorgesehen sind, und zwar getrennt für die Übertragung von axialen und radialen Kräften bezogen auf die Lagerachse.The The invention relates to a large rotational bearing for releasable Attachment of the upper part of a vehicle crane, excavator or the like. equipment on the relatively fixed undercarriage same device, wherein for transmission the rotational movement of the superstructure and the undercarriage each running surfaces provided for rolling elements are separate for the transfer related to axial and radial forces on the bearing axis.

Ein derartiges Großdrehlager ist beispielsweise aus der EP 1 239 172 B1 bekannt. Hierbei sind die Lagerteile jeweils am Oberwagen bzw. am Unterwagen angeschweißt und werden durch einen an beiden Lagerteilen (Lagerringen) umgreifenden Spannring zusammengehalten.Such a large rotary bearing is for example from the EP 1 239 172 B1 known. Here, the bearing parts are welded to the superstructure and the undercarriage and are held together by a clamping ring on both bearing parts (bearing rings).

In der Praxis sind auch Drehverbindungen bekannt, bei denen die Lagerteile nicht durch Schweißen, sondern durch Befestigungsschrauben mit dem Oberwagen und dem Unterwagen verbunden sind, wobei für die Befestigung am Obergurt des Unterwagens noch ein Auflagering vorgesehen ist.In In practice, rotary joints are also known in which the bearing parts not by welding, but by fastening screws with the superstructure and the undercarriage are connected, where for the attachment to the upper flange of the undercarriage nor a support ring is provided.

Aufgabe der Erfindung ist es die Drehlagerung zu vereinfachen, und zwar einerseits durch die Reduzierung der die Verbindung bildenden Teile und andererseits um die Montage und Demontage zu erleichtern.task The invention is to simplify the pivot bearing, namely on the one hand by reducing the parts forming the connection and on the other hand to facilitate assembly and disassembly.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, dass ein Lagerring am Oberwagen lösbar befestigt ist und eine Drehverbindung für den Oberwagen auf dem Unterwagen gelagert ist, wobei die Drehverbindung durch einen radial nach außen und innen wirkenden Spannring lösbar mit dem Obergurt des Unterwagens verbunden ist.Is solved this object according to the invention by that a bearing ring on the superstructure is releasably attached and a Rotary connection for the superstructure is mounted on the undercarriage, the rotary joint through a radially outward and inner clamping ring detachable is connected to the upper belt of the undercarriage.

Vorzugsweise ist am Oberwagen ein Lagerring befestigt, der zwei Laufflächen für die Wälzkörper zur Aufnahme axialer Kräfte aufweist, sowie eine Lauffläche für Wälzkörper zur Aufnahme radialer Kräfte,
dass eine ]-förmige Drehverbindung vorgesehen ist, die mit ihrem ⌋-förmigen Fuß auf dem Obergurt des Unterwagens aufliegt und an ihrem ⌉-förmigen Kopf korrespondierende Laufflächen aufweist,
und dass die Drehverbindung mit dem Unterwagen durch einen klauen- oder klammerartig den Fuß der Drehverbindung und den Obergurt des Unterwagens umfassenden, radial nach außen und innen wirkenden, Spannring lösbar miteinander verbunden sind. Der Spannring kann als Ganzes ausgeführt sein oder auch aus einzelnen, miteinander verbindbaren Segmenten bestehen.
Preferably, a bearing ring is attached to the superstructure, which has two running surfaces for the rolling elements for receiving axial forces, and a running surface for rolling elements for receiving radial forces,
that a] -shaped rotary joint is provided, which rests with its ⌋-shaped foot on the upper flange of the undercarriage and having at its ⌉-shaped head corresponding running surfaces,
and that the pivotal connection with the undercarriage by a claw-like or staple-like the foot of the rotary joint and the upper flange of the undercarriage comprehensive, radially outwardly and inwardly acting, clamping ring are releasably connected together. The clamping ring can be designed as a whole or consist of individual, interconnectable segments.

Durch diese erfindungsgemäße Art der Verbindung zwischen Oberwagen und Unterwagen entfallen gegenüber der herkömmlichen Montage der aufgeschweißte Auflagering sowie die Drehverbindungsschrauben. Damit entfällt aber auch die Montage und Wartung dieser Schrauben.By this inventive type of Connection between superstructure and undercarriage accounts for the usual Assembly of the welded Support ring and the rotary connection screws. But that does not apply also the assembly and maintenance of these screws.

Die Erfindung soll nachfolgend an einem in der Zeichnung dargestellten Ausführungsbeipiel erläutert werden, wobei die Drehverbindung hier nur teilweise dargestellt ist, und zwar im Querschnitt.The Invention is intended below to a shown in the drawing version Example explained be, with the rotary joint shown here only partially is, in cross section.

An dem Untergurt 2 des Oberwagens 1 ist mittels einer Schraubverbindung 3 der Lagerring 4 befestigt. Vom Unterwagen 5 ist ebenfalls nur der Obergurt 6 angedeutet. Der Obergurt ist mit einer offenen Ausnehmung 7 versehen, die einen Fuß 8 oder ein Fußteil einer Drehverbindung 9 aufnimmt.At the bottom strap 2 of the superstructure 1 is by means of a screw connection 3 the bearing ring 4 attached. From the undercarriage 5 is also just the upper belt 6 indicated. The upper strap is with an open recess 7 provided that one foot 8th or a foot of a rotary joint 9 receives.

Die Drehverbindung 9 bildet zusammen mit dem Lagerring 4 die Lager, und zwar die Axiallager 10 und Radiallager 11.The rotary joint 9 forms together with the bearing ring 4 the bearings, namely the thrust bearings 10 and radial bearings 11 ,

Die Drehverbindung 9 wird am Obergurt des Unterwagens durch einen den Fuß 8 und den Obergurt klauen- oder klammerartig umfassenden Spannring 12 gehalten, so dass damit dann die lösbare Verbindung zwischen Oberwagen 1 und Unterwagen 5 hergestellt wird.The rotary joint 9 gets on the upper belt of the undercarriage by one's foot 8th and the top chord or clamp-like clamping ring 12 held, so that then the detachable connection between the superstructure 1 and undercarriage 5 will be produced.
