Käfigloses Radial-WälzlagerCage-less radial roller bearing

Die Erfindung betrifft ein käfigloses Radial-Wälzlager mit einem äußeren und einem inneren Laufring, die "beide in einer durch die Achse gehenden Ebene geteilt sind, zwischen denen Wälzkörper abrollen.The invention relates to a cage-free radial roller bearing with an outer and an inner race, the "both." are divided in a plane passing through the axis, between which rolling elements roll.

Derartige Wälzlager bestehen aus einer Vielzahl von Einzelteilen, die sowohl beim Transport als auch im eingebauten Zustand fest miteinander verschraubt sind. Zum Einbau müssen die Schrauben jedoch entfernt werden, um die Lagerhälften in die vorgesehenen Lagerstellen einbringen zu können. Dabei bereitet es jedoch erhebliche Schwierigkeiten, die Lagerhälften so zusammenzuhalten, daß die losen Wälzkörper nicht herausfallen können.Such rolling bearings consist of a large number of individual parts, both during transport and in the built-in Are firmly screwed together. For installation, however, the screws must be removed in order to secure the bearing halves to be able to bring them into the designated storage locations. Included However, it causes considerable difficulties in the bearing halves hold together so that the loose rolling elements cannot fall out.

Man hat zwar schon versucht, die Wälzkörper mit Fett zwischen den Laufringhälften zu halten, diese Maßnahme hat sich aber als nicht sicher genug erwiesen und ist deshalb unbefriedigend.Attempts have already been made to hold the rolling elements between the halves of the race with grease, but this measure has worked not proven safe enough and is therefore unsatisfactory.

Nach einem anderen Vorschlag sind am inneren oder äußeren Laufring in geringem Abstand von den Wälzkörpern radial gerichtete Flansche vorgesehen, die entsprechend der Anzahl der Wälzkörper in Höhe des Teilkreises einander gegenüberliegend angeordnete Bohrungen aufweisen, in denen Schrauben mit einem Zentrieransatz angeordnet sind, die mit Spiel in zentrische Sackbohrungen in die Stirnflächen der Wälzkörper eingreifen. Eine solche Ausbildung verhindert zwar zuverlässig das Herausfallen der Wälzkörper, sie erfordert aberAccording to another suggestion are on the inside or outside Radial race at a small distance from the rolling elements directed flanges are provided, which are opposite to each other according to the number of rolling elements at the level of the pitch circle have arranged holes in which screws are arranged with a centering that with play in central blind bores engage in the end faces of the rolling elements. Such a training prevents reliably the falling out of the rolling elements, but it requires

ein so hohes Maß an Fertigungsaufwand, daß es preislich nicht vertretbar ist.such a high level of manufacturing effort that it is not justifiable in terms of price.

Der Erfindung liegt die Aufgabe zugrunde, die geschilderten Nachteile zu vermeiden und die Montage von käfiglosen Radial-Wälzlagern mit geringerem Aufwand wesentlich zu vereinfachen.The invention is based on the object of avoiding the disadvantages outlined and the assembly of cage-free radial roller bearings to simplify significantly with less effort.

Erfindungsgemäß wird dies dadurch erreicht, daß wenigstens an einer Lagerhälfte Mittel vorgesehen sind, durch die die Enden der inneren und äußeren Laufringhälften unter Einklemmen der Wälzkörper gegeneinander verspannbar sind.According to the invention this is achieved in that means are provided at least on one bearing half through which the Ends of the inner and outer race ring halves can be braced against one another with clamping of the rolling elements.

Nach einer möglichen Ausbildung der Erfindung wird hierzu vorgeschlagen, daß als Mittel zum Verspannen Schrauben vorgesehen sind, die durch Bohrungen der äußeren Laufringhälfte geführt und in Gewindebohrungen in der inneren Laufringhälfte eingeschraubt sind.According to one possible embodiment of the invention, it is proposed for this purpose that screws be provided as means for bracing are that through holes in the outer race half are guided and screwed into threaded holes in the inner raceway half.

Eine bevorzugte Ausführungsform der Erfindung sieht vor, daß das Wälzlager zwei Reihen von Wälzkörpern aufweist und die Schrauben zwischen den Wälzkörperreihen angeordnet sind.A preferred embodiment of the invention provides that the roller bearing has two rows of rolling elements and the screws are arranged between the rows of rolling elements.

Durch die erfindungsgemäß vorgeschlagene Ausbildung ergibt sich mit einfachen Mitteln der Vorteil, daß die Wälzkörper bei der Montage der Laufringhälften mit Sicherheit nicht mehr herausfallen können, so daß der Montagevorgang nicht nur erleichtert sondern wegen der besseren Handhabung der Lagerhälften auch verkürzt wird.The design proposed according to the invention results, with simple means, in the advantage that the rolling elements During the assembly of the raceway halves can certainly no longer fall out, so that the assembly process does not only made easier but also shortened because of the better handling of the bearing halves.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben; Es zeigen:An embodiment of the invention is shown in the drawing and is described in more detail below; It demonstrate:

Das Wälzlager besteht aus dem äußeren Laufring 1, dem inneren Laufring 2 und den Spännringen 3 und 4, die alle in der durch die Achse gehenden Ebene 5 geteilt sind, so daß zwei Lagerhälften 6 und 7 gebildet werden. Die Hälften .des äußeren Laufringes 1 sind durch die Schrauben miteinander verbunden, während die den äußeren Laufring in beiden axialen Richtungen überragenden Hälften des inneren Lauf ringes 2 mittels der Schrauben 9 in den Spannringen 3 und 4 zusammengehalten sind. Zwischen dem äußeren Laufring 1 und dem inneren Laufring.2 sind zwei Reihen zylindrischer Wälzkörper 10 vorgesehen. :The roller bearing consists of the outer race 1, the inner race 2 and clamping rings 3 and 4, all are divided in plane 5 passing through the axis, so that two bearing halves 6 and 7 are formed. the Halves of the outer race 1 are through the screws connected to one another, while the halves of the outer raceway projecting in both axial directions inner race ring 2 by means of the screws 9 in the clamping rings 3 and 4 are held together. Between the outer Race 1 and the inner race 2 are two rows cylindrical rolling element 10 is provided. :

Bei der Lagerhälfte 7 sind die Enden des äußeren Laufringes und des inneren Laufringes 2 durch Schrauben 11 derart gegeneinander verspannt, daß die Wälzkörper 10 eingeklemmt sind. Zu diesem Zweck weist der äußere Laufring 1 Bohrungen und der innere Laufring 2 Gewindebohrungen 13 auf.At the bearing half 7 are the ends of the outer race and the inner race 2 by screws 11 so against each other braced that the rolling elements 10 are clamped.
