Description

Lagersystem mit Rollenlagern. Den Gegenstand der Erfindung bildet eine Lagerung, insbesondere für Naben der Wagen-oder Automobilräder oder für die Räder von Schienenfahrzeugen, die aber auch für andere Zwecke angewendet werden kann. Die Erfindung bezweckt, die bei der Lagerung verwendeten Laufringrollenlager gegen Verschiebung und gegen Wandern auf dem Achszapfen sicher festzustellen, trotz dieses festen Einbaues aber auch ein leichtes Abziehen der Lager zuzulassen. Dies wird bei dem Lagersystem dadurch erzielt, daß die inneren Laufringe der Rollenlager auf einer Tragebüchse mit Preßsitz aufgezogen sind, während die Büchse ihrerseits auf den Achszapfen ohne großen Kraftaufwand abziehbar sitzt und auf diesem durch geeignete Sicherungsmittel, wie Schrauben o. dgl., gegen Drehung und Verschiebung festgehalten wird. Bei diesem Lageraufbau sind die inneren Laufringe durch Widerlager in achsialer Richtung gestützt. Die Schwierigkeit, daß die Lagerringe mit Preßsitz befestigt werden müssen, wird gemäß der Erfindung dadurch behoben, daß die diese Ringe tragende Hülse- abziehbar auf dem Achszapfen angebracht ist.Storage system with roller bearings. Forms the subject of the invention a storage, especially for hubs of the car or automobile wheels or for the Wheels of rail vehicles, which are also used for other purposes can. The aim of the invention is the roller bearing used in storage secure against displacement and against wandering on the stub axle, in spite of it this fixed installation but also allow easy removal of the bearings. this is achieved in the bearing system in that the inner races of the roller bearings on a carrying sleeve with a press fit, while the sleeve in turn the axle journal sits removable without great effort and on this by suitable Securing means, such as screws or the like, held against rotation and displacement will. With this bearing structure, the inner races are axially aligned by abutments Direction based. The difficulty that the bearing rings are attached with an interference fit have to be resolved according to the invention in that the one carrying these rings Sleeve is attached to the axle journal so that it can be pulled off.

Auf der Zeichnung ist die Lagerung in zwei Anwendungsbeispielen dargestellt. Abb. i - zeigt den Lagereinbau eines Automobilrades. Abb. 2 stellt den gleichen Einbau in der Achsbüchse eines Schienenfahrzeuges dar.In the drawing, the storage is shown in two application examples. Fig. I - shows the bearing installation of an automobile wheel. Fig. 2 represents the same Installation in the axle sleeve of a rail vehicle.

Bei der Lagerung sind die beiden Kränze zylindrischer Rollen 3 und q. beiderseits -an festen Schultern der inneren Laufringe 5 und 6 spielfrei geführt, wohingegen sie an den äußeren Laufringen 7 und 8 nur auf einer Seite durch eine Stützschulter g und io gegen Verschiebung gehalten werden. Die eine Schulter, z. B. g, kann lösbar sein, d. h. von einem getrennten Ring gebildet werden; um die inneren Lagerteile nebst denRollen aus derNabeii leichtherausziehen zu können, nachdem der Deckel 12 gelöst worden ist. Die inneren Laufringe 5 und 6 sind mit Festsitz auf eine Tragebüchse 13 aufgeschoben, die auf dem Achszapfen 1q. sitzt und mittels Schrauben 15 oder anderer geeigneter Befestigungsmittel, z. B. einer Mutter, gegen Verschiebung und Drehung gesichert ist. Zwischen den inneren Laufringen 5 und 6 ist eine Abstandshülse 17 angeordnet, während die Ringe auf ihren äußeren Seiten einerseits durch einen Flansch 18 der Tragebüchse 13 anderseits durch einen Absatz ig des Achszapfens gehalten werden. Die äußeren Laufringe werden ebenfalls durch eine Zwischenhülse 24 in gewissem Abstande voneinander und durch eine Schulter 2o und einen ringförmigen Vorsprung 21 des Deckels 12 gegen Verschiebung in der Nabe ii festgehalten. Die Rollenkränze werden zweckmäßig* durch Führungsringe 22 in der üblichen Weise zusammengehalten. Zwischen der Achse und der Nabe ist eine Staubdichtung 23 beliebiger bekannter Ausführungsform angewendet.In storage, the two rings of cylindrical rollers 3 and q. on both sides-on fixed shoulders of the inner races 5 and 6 without play, whereas they are held against displacement on the outer races 7 and 8 only on one side by a support shoulder g and io. One shoulder, e.g. B. g, can be detachable, ie formed by a separate ring; in order to be able to easily pull the inner bearing parts together with the rollers out of theNabeii after the cover 12 has been loosened. The inner races 5 and 6 are pushed onto a support sleeve 13 with an interference fit, which is on the journal 1q. sits and by means of screws 15 or other suitable fastening means, e.g. B. a mother, is secured against displacement and rotation. A spacer sleeve 17 is arranged between the inner races 5 and 6, while the rings are held on their outer sides by a flange 18 of the support sleeve 13 on the one hand by a shoulder ig of the journal. The outer races are also held at a certain distance from one another by an intermediate sleeve 24 and by a shoulder 2o and an annular projection 21 of the cover 12 against displacement in the hub ii. The roller rings are appropriately * held together by guide rings 22 in the usual manner. A dust seal 23 of any known embodiment is applied between the axle and the hub.

Die Laufringe der einzelnen Rollenlager können anders ausgeführt sein und- unter Umständen auch aus einem Stück bestehen. Ebenso wird die Wirkung nicht verändert, wenn die Schultern an den Ringen angefügt sind. Die Rollen können schwach ballig sein. Es ist vor allen Dingen wesentlich, daß der Festsitz zwischen der undrehbar befestigten Tragehülse und den inneren Laufringen vorgesehen und die Abziehbarkeit durch die auf die Achse aufschiebbare Tragehülse gegeben ist.The races of the individual roller bearings can be designed differently and- possibly consist of one piece. Likewise, the effect will not changed when the shoulders are attached to the rings. The roles can be weak be convex. Above all, it is essential that the tight fit between the non-rotatable attached support sleeve and the inner races provided and the removability is given by the support sleeve that can be pushed onto the axle.

Die Lageranordnung wirkt in folgender Weise Infolge der Anwendung von festen Schultern an den Innenringen werden die Rollen spielfrei geführt, während die Anwendung einer Schulter am Außenring die achsiale Stützung ergibt, jedoch im übrigen die freie Beweglichkeit der Rollen zuläßt. Man kann bei dieser Anordnung die Rollenkränze dadurch aus der Nabe oder dem Gehäuse leicht ausziehbar machen, daß man eine oder mehrere Schultern, namentlich an den Außenringen, lösbar ausführt. Vorteilhaft geschieht dies bei dem auf dem äußeren Ende des Achszapfens sitzenden, d. h. dem vorderen Lager, wie in der Zeichnung dargestellt ist. In diesem Falle läßt sich nach Lösen des Verschlußteiles das gesamte Rollensystem nach dieser Seite herausziehen. Dies ist von großem Vorteil, wenn es sich um eine Achslagerung für Schienenfahrzeuge handelt. Der Wagen braucht dann nicht aus der Federpfanne ganz herausgehoben zu werden, vielmehr genügt ein leichtes Anheben, um die Rollenlager zu entlasten und dann beim Herabziehen der Tragebüchse 13 vom Achszapfen die beiden Rollenkränze, die sich dabei an den Laufbahnen der äußeren Ringe entlang bewegen, herauszuziehen. Das gesamte Lager kann dann leicht nachgesehen und gereinigt werden, ohne es vorher weiter zu zerlegen. Man kann also je nach Bedarf das ganze Lager oder nur einzelne Teile entfernen, wobei in jedem Falle die Tragebüchse das leichte Abziehen der Rollenlager ermöglicht, in der Arbeitsstellung jedoch einen Festsitz der inneren Laufringe bewirkt, so daß das Wandern der Ringe und die dadurch herbeigeführte Abnutzung verhütet wird. In gleicher- Weise können die äußeren Laufringe in der Nabe fest eingepreßt werden.The bearing arrangement acts in the following manner due to the application solid shoulders on the inner rings guide the roles without play, while the use of a shoulder on the outer ring provides axial support, but in the rest of the freedom of movement of the roles allows. One can use this arrangement make the roller and cage assemblies easy to pull out of the hub or the housing, that one or more shoulders, especially on the outer rings, are detachable. This is advantageously done with the one sitting on the outer end of the stub axle, d. H. the front bearing as shown in the drawing. In this case After loosening the locking part, the entire roller system can be moved to this side pull out. This is of great advantage when it comes to axle bearings Rail vehicles deals. The car then does not need to be completely out of the spring pan to be lifted out, rather a slight lifting is sufficient to the roller bearing to relieve and then when pulling down the carrying sleeve 13 from the stub axle, the two Roller and cage assemblies, which move along the raceways of the outer rings, pull out. The entire warehouse can then be easily checked and cleaned, without taking it apart first. So you can use the whole camp depending on your needs or just remove individual parts, in which case the carrying sleeve is the easy one Pulling off the roller bearing allows, but a tight fit in the working position of the inner races causes, so that the wandering of the rings and the thereby brought about Wear is prevented. In the same way, the outer races in the Be firmly pressed in the hub.
