Description

Elastische Lagerbuchse Die vorliegende Erfindung betrifft eine elastische Lagerbuchse mit auf ihrem Umfang durchlaufenden Längsschlitzen. Diese Lagerbuchse soll größere Toleranzen in Bohrungen, die zu ihrer Aufnahme bestimmt sind, ausgleichen. Ein solcher Ausgleich ist bei einer geringen Reibungsbelastung der Buchse ohne weiteres möglich. Es ist bereits bekannt, unter Verwendung mehr oder minder elastischer Werkstoffe Lagerbuchsen als durchgehendes Rohrprofil zu gestalten und deren Außen- bzw. Innenfläche mit durchlaufenden Längsschlitzen bzw. -aussparungen so zu versehen, daß die Buchse nach dem Einfügen fest in ihrem Träger sitzt. Bei diesen bekannten Buchsen wird aber eine Verformung des Materials zu Hilfe gezogen, die zu erheblichen Innenspannungen führt, die bei schwachwandigen Bohrungen oder sprödem Material sich nachteilig auswirken.Elastic bushing The present invention relates to an elastic bushing Bearing bush with longitudinal slots running through its circumference. This bearing bush is intended to compensate for larger tolerances in bores that are intended to accommodate them. Such a compensation is easy with a low frictional load on the bushing possible. It is already known to use more or less elastic materials Design bearing bushes as a continuous tubular profile and their outer or inner surface to be provided with continuous longitudinal slots or recesses so that the socket sits firmly in its carrier after insertion. In these known sockets but a deformation of the material is drawn to the aid, which leads to considerable internal stresses leads that have a detrimental effect on weak-walled bores or brittle material.

Nach der Erfindung wird eine Verformung des Werkstoffes bewußt vermieden und eine für Rohre besonders geeignete, billige und einfache Buchse vorgeschlagen, die größere Toleranzen im Innendurchmesser des Rohres ausgleichen soll.According to the invention, deformation of the material is deliberately avoided and proposed a cheap and simple bushing particularly suitable for pipes, which is intended to compensate for larger tolerances in the inner diameter of the pipe.

Neuheitsgemäß sind die am Außenmantel der Buchse vorgesehenen Längsschlitze schräg zur Manteloberfläche gerichtet, und die durch die Schlitze getrennten Lagerflächen weisen verschiedene Durchmesser auf, derart, daß sie sich beim Einsetzen der Buchse unter Vermeidung von wesentlichen Werkstoffverformungen in die Längsschlitze durch Einbiegen einlegen können. Die federnde Gestaltung und Anordnung der Lagerflächen der Buchse ergibt einen Sitz der Buchse in der zugehörigen Trägerbohrung, der jedes Klappern der Buchse während des Betriebes vermindert und darüber hinaus einen leichten Einbau zuläßt, der die Gefahr des Berstens der Trägerbohrung und damit einen Ausschußanfall verhindert.The longitudinal slots provided on the outer jacket of the socket are new directed obliquely to the jacket surface, and the bearing surfaces separated by the slots have different diameters so that they are when the bushing is inserted while avoiding significant material deformations in the longitudinal slots Can insert bending. The resilient design and arrangement of the bearing surfaces the bushing results in a seat of the bushing in the associated carrier bore, which each Rattling of the socket during operation is reduced and, in addition, a slight rattle Installation allows the risk of bursting the carrier bore and thus a reject rate prevented.

Die Erfindung ist in der Zeichnung an Hand eines Ausführungsbeispiels dargestellt und beschrieben. Fig. 1 zeigt eine Ansicht der Buchse, Fig. 2 einen Querschnitt.The invention is shown in the drawing using an exemplary embodiment shown and described. Fig. 1 shows a view of the socket, Fig. 2 shows a Cross-section.

Mit 1 ist der aus Kunststoff, z. B. aus Polyamid, bestehende ringförmige Körper bezeichnet, dessen Außenmantel regelmäißge, über den Umfang regelmäßig verteilte Ein- und Ausschnitte aufweist. Die Ausschnitte 2 dienen ebenso wie die schlitzförmigen Einschnitte 3 zur Erzielung elastischer Lappen 4, die einen größeren Manteldurchmesser aufweisen als die zwischen den Lappen 4 liegenden Teilanschnitte 5. Die Lappen 4 können mit ihrer Mantelfläche auf den Durchmesser der Teilausschnitte 5 einfedern. Dadurch ist die Buchse für den Einbau in Bohrungen geeignet, deren Bohrungsdurchmesser Toleranzen zwischen dem Manteldurchmesseer der Lappen 4 und dem Manteldurchmesser der Teilausschnitte 5 aufweist.With 1 is made of plastic, for. B. made of polyamide, existing annular Body referred to, the outer jacket of which was regularly distributed over the circumference Has incisions and cutouts. The cutouts 2 serve as well as the slot-shaped ones Incisions 3 to achieve elastic flaps 4, which have a larger jacket diameter than the partial cuts 5 lying between the tabs 4. The tabs 4 can deflect with their outer surface to the diameter of the partial cutouts 5. This makes the bushing suitable for installation in bores whose bore diameter Tolerances between the jacket diameter of the tabs 4 and the jacket diameter which has partial cutouts 5.
