Description

Mittenfreie Wälzlager-Drehverbindung Center-free rolling bearing slewing ring

Die Erfindung betrifft eine mittenfreie Wälzlager-Drehverbindung, bestehend aus zwei konzentrischen Laufringen, von denen der eine eine umlaufende, zum anderen Laufring hin offene Nut, und der andere Laufring einen umlaufenden, mit allseitigem Abstand in die Nut eingreifenden Vorsprung von rechteckigem Querschnitt besitzt, und wobei zwischen der zylindrischen Mantelfläche des Vorsprunges einerseits und einer korrespondierenden Zylinderfläche der Nut andererseits Zylinderrollen zur Aufnahme von Radialkräften, und zwischen den parallelen Stirnflächen des Vorsprunges einerseits und korrespondierenden Stirnflächen der Nut andererseits zwei Sätze von Zylinderrollen zur Aufnahme von Axialkräften vorgesehen sind.The invention relates to a center-free roller bearing slewing ring, consisting of two concentric races, one of which has a circumferential, to the other raceway open groove, and the other raceway a circumferential, with a spacing on all sides in the groove engaging projection of rectangular cross-section possesses, and wherein between the cylindrical lateral surface of the projection on the one hand and a corresponding cylindrical surface of the groove, on the other hand, cylindrical rollers to absorb radial forces, and between the parallel end faces of the projection on the one hand and corresponding end faces of the groove on the other hand two sets of Cylindrical rollers are provided to absorb axial forces.

Derartige bekannte Lager sind sehr gut geeignet, um hohe Belastungen in radialer und insbesondere axialer Richtung aufzunehmen. Um solche Lager zusammenbauen zu können, hat man den die Nut aufweisenden Laufring im Bereich der Nut entlang einer quer zur Lagerachse verlaufenden Ebene in zwei Teile geteilt. Diese beiden Ringteile mußten nach der Montage durch Schrauben miteinander verbunden werden, die in einem Bereich des Ringes angeordnet werden mußten, der sich radial zur Nut erstreckt. Diesen zusätzlich erforderlichen radialen Bauraum für die Verbindungsschrauben nutzte man gleichzeitig dazu, um in diesem Bereich des Ringes auch die Bohrungen anzuordnen, die zu seiner Befestigung an weiteren Bauteilen dienen. Dieser zusätzliche benötigte radiale Bauraum ist in vielen Einbaufällen, bei denen nur relativ wenig radialer Platz zur Verfügung steht, nachteilig.Such known bearings are very well suited to high loads take up in the radial and in particular the axial direction. To assemble such bearings to be able to, one has the raceway having the groove along in the area of the groove a plane running transversely to the bearing axis is divided into two parts. These two Ring parts had to be connected to one another by screws after assembly, which had to be arranged in an area of the ring that is radially to the groove extends. This additionally required radial installation space for the connecting screws was used at the same time to drill the holes in this area of the ring to be arranged, which are used to attach it to other components. This additional required radial There is installation space in many installation cases where only relatively little radial space is available, disadvantageous.

Es ist bei diesen Lagern weiterhin konstruktionsbedingt, daß der die Nut aufweisende Laufring in axialer Richtung breiter ausgebildet werden muß als der Laufring mit dem Vorsprung. In den häufigen Fällen, in denen einer der Laufringe mit einer Verzahnung versehen werden muß, würde sich somit der die Nut aufweisende Laufring hierfür anbieten, weil an ihm ohne zusätzlichen Aufwand eine größere Zahnbreite erzielbar wäre als an dem anderen Laufring. Durch die Teilung dieses Laufringes und das nachträgliche Zusammenfügen der beiden Teile ist es jedoch nicht möglich, an diesem Ring eine Verzahnung anzubringen, durch die sich die Teilfuge erstrecken müßte, was zwangsläufig zur Folge hätte, daß die einzelnen Zähne niemals über ihre gesamte Länge gleichmäßig tragen können.It is also due to the design of these camps that the Grooved running ring must be made wider in the axial direction than the race with the protrusion. In the common cases where one of the races must be provided with a toothing, the one having the groove would be Offer a running ring for this because it has a larger face width without additional effort would be achievable than on the other race. By dividing this raceway and the subsequent joining of the two parts, however, it is not possible to attach a toothing to this ring, through which the parting line extends would have to, which inevitably would mean that the individual teeth never over their be able to wear the entire length evenly.

Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile zu vermeiden und ein Lager dieser Bauart zu schaffen, das radial kleiner als die bisher bekannten baut und bei welchem die Verzahnung ohne schädliche Einflüsse an dem die Nut aufweisenden Laufring angebracht werden kann.The invention is based on the described disadvantages to avoid and to create a bearing of this type that is radially smaller than the previously known builds and in which the toothing without harmful influences can be attached to the raceway having the groove.

Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß der die Nut aufweisende Laufring einteilig ausgebildet ist, während der mit dem Vorsprung versehene Laufring aus mehreren Segementen besteht, die mit einem weiteren einteiligen Ring verbunden sind. Diese Bauart läßt den Zusammenbau des Lagers dadurch zu, daß die Segmente des mit dem Vorsprung versehenen Laufrings nach dem Einbringen der Wälzkörper in die Nut des anderen Laufringes eingeführt werden können. Abschließend werden diese Segmente mit dem weiteren einteiligen Ring verbunden, z.B. verschraubt, wodurch die Lagereinheit fertiggestellt ist.According to the invention, this object is achieved in that the Groove having the raceway is formed in one piece, while with the projection The raceway provided consists of several segments that are integral with another Ring are connected. This design allows the assembly of the bearing in that the segments of the raceway provided with the projection after the introduction of the Rolling elements can be introduced into the groove of the other race. Finally these segments are connected to the further one-piece ring, e.g. screwed, whereby the storage unit is completed.

Bei dieser Konstruktion kann der die Nut aufweisende Laufring radial äußerst kleine Abmessungen aufweisen, denn die Gewindebohrungen zu seiner Befestigung können im wesentlichen axial von der Nut angeordnet sein.With this construction, the raceway having the groove can be radial have extremely small dimensions, because the threaded holes for its attachment can be arranged substantially axially of the groove.

Auch kann bei dieser Konstruktion der die Nut aufweisende Laufring an seiner der Nut entgegengesetzten Mantelfläche mit einer Verzahnung versehen sein.In this construction, the raceway having the groove can also be provided with a toothing on its lateral surface opposite the groove.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigen: Fig. 1 einen Teil-Längsschnitt durch ein erfindungsgemäßes Lager und Fig. 2 eine Ansicht entsprechend Pfeil II nach Figur 1.An exemplary embodiment of the invention is shown in the drawing. 1 shows a partial longitudinal section through a bearing according to the invention, and FIG FIG. 2 shows a view according to arrow II according to FIG. 1.

Das dargestellte Lager besteht aus dem Laufring 1, der die Nut 2 aufweist und aus dem Laufring 3, der den Vorsprung 4 besitzt. Zwischen der Nut 2 und dem Vorsprung 4 sind die Wälzkörper 5 zur Aufnahme der Radialkräfte sowie die beiden Wälzkörpersätze 6 zur Aufnahme der Axialkräfte vorgesehen.The bearing shown consists of the race 1, which has the groove 2 and from the race 3, which has the projection 4. Between the groove 2 and the Projection 4 are the rolling elements 5 for absorbing the radial forces and the two Rolling element sets 6 provided for absorbing the axial forces.

Wie Figur 2 erkennen läßt, ist der Laufring 3 durch Teilfugen 7 in einzelne Segmente geteilt. Diese Segmente werden am Ende des Zusammenbaues des Lagers mit dem einteiligen Ring 8 durch Schrauben 9 verbunden. In diesem sich radial erstreckenden Teil des Laufringes 3 sind auch die Gewindebohrungen 10 zu seiner Befestigung an weiteren Bauteilen vorgesehen. Im Gegensatzu dazu sind die Gewindebohrungen 11 an dem Laufring 1 so angeordnet, daß sie sich im wesentlichen axial zu der Nut 2 erstrecken, was zur Folge hat, daß der Laufring 1 nur sehr geringe radiale Abmessungen besitzt. Der Laufring 1 kann auch, wie die Figuren zeigen, an seiner inneren, der Nut entgegengesetzten Mantelfläche mit einer Verzahnung 12 versehen sein, die, bedingt durch die konstruktiv erforderliche große axiale Erstreckung des Laufringes 1 eine große tragende Länge besitzt.As can be seen in FIG. 2, the race 3 is in by butt joints 7 individual segments divided. These segments will be used at the end of the assembly of the bearing connected to the one-piece ring 8 by screws 9. In this radially extending Part of the race 3 are also the threaded holes 10 for its attachment further components provided. In contrast, the threaded holes 11 are on the race 1 arranged so that they extend substantially axially to the groove 2, with the result that the race 1 has only very small radial dimensions. The race 1 can also, as the figures show, at its inner, opposite to the groove Outer surface be provided with a toothing 12, which, due to the constructive required large axial extension of the race 1 a large load-bearing length owns.
