Description

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, sowie mit Mitteln zum Halten der Wälzkörper in den Laufringhälften während der Montage des Lagers.The invention relates to a cage-free radial roller bearing with an outer and an inner race, both divided in a plane passing through the axis are, between which rolling elements roll, as well as with means for holding the rolling elements in the raceway halves during the assembly of the bearing.

Derartige Wälzlager b jstehet aus einer Vielzahl von Einzelteilen, die sowohl ksira Transport als auch im eingebauten Zustand fest miteinaiv ;r verschraubt sind. Zum Einbau müssen die Schrauben jedoch entfernt werden, um die Lagerhälften in die vorgesehenen Lagerstellen einbringen zu können.Such rolling bearings are made up of a large number of Individual parts that are used by ksira Transport as well as im installed state are firmly screwed to one another. For installation, however, the screws must be removed in order to put the bearing halves in the intended To be able to bring in storage locations.

Dabei bereitet es jedoch erhebliche Schwierigkeiten, die Lagerhälften so zusammenzuhalten, daß die losen Wälzkörper nicht herausfallen können.However, there is considerable difficulty in holding the bearing halves together so that the loose ones 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 race ring halves with grease, these However, the measure has not proven to be safe enough and is therefore unsatisfactory.

Nach einem anderen Vorschlag sind am inneren und 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 den Stirnflächen der Wälzkörper eingreifen (DE-GM 72 08 726). Eine solche Ausbildung verhindert zwar zuverlässig das Herausfallen der Wälzkörper, sie erfordert aber ein so hohes Maß an Fertigungsaufwand, daß es preislich nicht vertretbar istAccording to another proposal, the inner and outer races are at a small distance from the Rolling elements radially directed flanges are provided, which correspond to the number of rolling elements in the amount of Part circle have oppositely arranged holes in which screws with a Centering approach are arranged with play in central blind holes in the end faces of the Engage rolling elements (DE-GM 72 08 726). Such a training reliably prevents it from falling out the rolling elements, but it requires such a high level of manufacturing expenditure that it is not justifiable in terms of price is

Der Erfindung liegt die Aufgabe zugrunde, die ϊ Montage von käfiglosen Radial-Wälzlagern mit geteilten Lanfringen durch Mittel zu vereinfachen, die die Wälzkörper unverlierbar mit den Laufringhälften verbinden.The invention is based on the task of the ϊ assembly of cage-less radial rolling bearings with split To simplify Lanfringen by means that the rolling elements cannot be lost with the raceway halves associate.

Erfindungsgemäß wird dies dadurch erre^ht, daßAccording to the invention this is achieved in that

ίο wenigstens an einer Lagerhälfte Mittel vorgesehen sind, durch die die Enden der inneren und äußerenίο means are provided on at least one half of the bearing, through which the ends of the inner and outer

Laufringhälften unter Einklemmen der WälzkörperRace halves with wedging of the rolling elements

gegeneinander verspannbar sind.are braced against each other.

Nach einer möglichen Ausbildung der Erfindung wirdAccording to a possible embodiment of the invention

r> 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.
Eine bevorzugte Ausführungsform der. Erfindung sieht vor. daß das Wälzlager zwei Reihen von Wälzkörpern aufweist und die Schrauben zwischen den Wälzkörperreihen angeordnet sind.In this regard, it is proposed that screws are provided as means for bracing, which are guided through bores in the outer race ring half and screwed into threaded holes in the inner race ring half.
A preferred embodiment of the. Invention provides. that the rolling 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 The design proposed according to the invention results, with simple means, in the advantage that

die Wälzkörper bei der Montage derLaufringhälften mit Sicherheit nicht mehr herausfallen können, so daß der Montagevorgang eicht nur erleichtert, sondern wegen der besseren Handhabung der Lagerhälften auch verkürzt wird.the rolling elements can certainly no longer fall out during the assembly of the race ring halves, so that the The assembly process is only made easier, but also because of the better handling of the bearing halves is shortened.
