Wälzlagerroller bearing

Die Neuerung betrifft ein Wälzlager, dessen Außenlaufring von einer elastischen, beispielsweise aus Kunststoff bestehenden Hülse umgeben ist.The innovation concerns a roller bearing, its outer race is surrounded by an elastic, for example made of plastic sleeve.

Wälzlager dieser Art sind bereits in den verschiedensten Ausführungen bekannt geworden. So hat man beispielsweise den Außenlaufring mit e.\ner elastischen Hülse aus Kunststoff oder Gummi umgeben, um damit in einfacher Weise eine Schwingungsdämpfung zu erreichen. Zur Abdichtung solcher Wälzlager sind bereits elastische Hülsen bekannt geworden, die ein- oder beidseitig radial nach innen gerichtete Dichtlippen aufweisen. Weiterhin ist es nicht mehr neu, die äußere Mantelfläche solcher Hülsen mit axial verlaufenden Ausnehmungen zu versehen, um dadurch einen Toleranzausgleich zi erzielen.Rolling bearings of this type are already known in a wide variety of designs. So you have, for example Surround the outer race with an elastic sleeve made of plastic or rubber, in order to make it easy to achieve vibration damping. Elastic sleeves are already known for sealing such rolling bearings become, which have one or both sides radially inwardly directed sealing lips. Furthermore it is not more new to provide the outer surface of such sleeves with axially extending recesses to thereby achieve a tolerance compensation zi.

Lager der letztgenannten Art bringen den erheblichen Vorteil, daß bei der Bearbeitung der Lagerbohrung eine größere Tolerierung möglich ist» wodurch nicht unbeträchtliche Einsparungen erzielt werden. Der Einsatz solcher Lager ist jedoch auf Anwendungsgebiete beschränkt, bei denen eine Abdichtung zwischen Lager und Gehäus9bohrung nicht erforderlich ist.Bearings of the last-mentioned type have the considerable advantage that when machining the bearing bore, a larger one Tolerance is possible »which results in not inconsiderable savings. The use of such bearings is however limited to areas of application in which a seal between the bearing and the housing bore is not required is.

Der Neuerung liegt die Aufgabe zugrunde, in einfacher Weise die bekannten Ausführungen zu verbessern, was durch dieThe innovation is based on the task of improving the known designs in a simple manner, which is achieved by the

Γ G 1360 - 2 -Γ G 1360 - 2 -

Schaffung einer Abdichtung zwischen Lager und Gehäusebohrung ohne großen Aufwand erreicht wird.Creation of a seal between the bearing and the housing bore is achieved without great effort.

Neuerungsgemäß wird dies durch die Kombination folgender Merkmale erreicht:According to the innovation, this is achieved by combining the following features:

a) die Hülse v/eist an einem oder beiden Enden radial nach innen gerichtete Dichtlippen auf,a) the sleeve has sealing lips directed radially inward at one or both ends,

b) die äußere Mantelfläche der Hülse ist mit einer Vielzahl von über den Umfang der Hülse verteilten axial verlaufenden Ausnehmungen versehen, undb) the outer surface of the sleeve is axially extending with a plurality of distributed over the circumference of the sleeve Provided recesses, and

c) jede Ausnehmung ist durch einen, sich nur über einen geringen Teil ihrer Länge erstreckenden Steg abgeschlossen.c) each recess is closed by a web that extends only over a small part of its length.

Die neuerungsgemäß vorgeschlagene Ausbildungsform gewährleistet mit einfachen Mitteln auch eine einwandfreie Abdichtung zwischen Lager und Gehäusebohrung, ohne die genannten Vorteile der bekannten Ausführungen zu beeinträchtigen. Dadurch ergibt sich ohne nennenswerten Aufwand eine Lagerausführung, die we'tere Anwendungsbereiche erschließt.The embodiment proposed according to the innovation also ensures a perfect seal with simple means between the bearing and the housing bore without impairing the stated advantages of the known designs. Through this This results in a bearing design that opens up further areas of application without any significant effort.

Ein Ausführungsbeispiel der Neuerung ist in der Zeichnung , dargestellt und wird im folgenden näher beschrieben.An embodiment of the innovation is illustrated in the drawing and will be described in more detail below.

Besonders vorteilhaft ist die beschriebene Ausführung dann, wenn ein dünnwandiger, insbesondere spanlos gefertigter Außenlaufring Verwendung f'ndet. Dabei wird durch die vorgeschlagene Ausbildung der elastischen Hülse außer einer inneren und äußeren Abdichtung des Wälzlagers ein sicherer Toleranzausgleich erreicht, ohne daß eine unzulässige Verformung des Außenlaufringes eintritt.The embodiment described is particularly advantageous when a thin-walled, in particular one manufactured without cutting Outer race is used. In doing so, the proposed Formation of the elastic sleeve apart from an inner and outer sealing of the roller bearing a safer one Tolerance compensation achieved without inadmissible deformation of the outer race occurring.

Die Neuerung ist jedoch nicht auf das gezeigte Ausführungsbeispiel beschränkt. Sie ist durchaus auch mit Erfolg bei Wälzlagern mit massivem Außenring anwendbar. Ebenso ist es unerheblich, welche Art von Wälzkörpern für die vorgeschlagene Neuerung Verwendung finden.However, the innovation is not limited to the exemplary embodiment shown. She is also quite successful at Rolling bearings with a solid outer ring can be used. It is also irrelevant what type of rolling elements for the proposed Find innovation use.
