Abstract

The chain link has two-part bushes around the bolts (2) which join the links together. An inner sliding bearing bush section (11) is of a self-lubricating polymer. The outer bush section (1) is bonded to the inner side bars (4), and the outer side bars (5) rest on the end sides of the outer bush.

Description

Die Erfindung bezieht sich auf Gelenkketten, bestehend aus mittels Kettenbolzen miteinander verbundenen Kettengliedern und aus Innen- und Außenlaschen sowie Buchsen, die die mit den Außenlaschen verbundenen Kettenbolzen umgeben, ihrerseits mit den Innenlaschen verbunden sind und außerhalb der Innenlaschen jeweils einen den Abstand zwischen Außenlaschen und Innenlaschen festlegenden Überstand haben.The The invention relates to articulated chains consisting of chain pins interconnected chain links and inner and outer links as well as bushings which connect the chain pins connected to the outer links surrounded, in turn, are connected to the inner straps and outside the inner plates each one the distance between outer plates and inner straps defining overhang to have.

Die Erfindung bezieht sich insbesondere auf sog. Stahlgelenkketten. Insofern betrifft die Erfindung hauptsächlich die in den DIN-Normen 8187, 8188 sowie 8164 definierten Rollenketten bzw. Buchsenketten.The The invention relates in particular to so-called steel link chains. In this respect, the invention mainly relates to those in the DIN standards 8187, 8188 and 8164 defined roller chains or bush chains.

Der Erfindung liegt die Aufgabe zugrunde, eine Kette der eingangs genannten Art so auszugestalten, dass sie praktisch wartungsfrei ist.Of the Invention is based on the object, a chain of the aforementioned Design the way that it is virtually maintenance-free.

Erreicht wird dies dadurch, dass die Buchsen zweiteilig ausgebildet sind und aus einem inneren Polymer-Gleitlager und einer äußeren Trägerbuchse bestehen und dass alle Kettenbauteile bis auf das Polymer-Gleitlager aus rostbeständigen Edelstählen gebildet sind.Reached This is because the bushes are formed in two parts and consist of an inner polymer slide bearing and an outer bushing and that all chain parts except for the polymer plain bearing rustproof Stainless steels formed are.

Durch die Überstände zu beiden Seiten der Innenlaschen gegenüber den Außenlaschen kann erreicht werden, dass die Kettenlaschen nicht aufeinanderreiben können. Da nun die Buchsen aus selbstschmierendem Material bzw. aus einem inneren reibungsarmen Polymer-Gleitlager gebildet sind, können dort, wo metallische Berührungen auftreten, auch gleichzeitig Schmierungseigenschaften sichergestellt werden, und dies insgesamt ist der Hauptgrund dafür, dass die Kette gemäß der Erfindung wartungsfrei ist.By the supernatants to both Opposite sides of the inner plates the outer plates can be achieved that the link plates do not rub against each other can. Since now the sockets of self-lubricating material or from a inner low-friction polymer plain bearings are formed there, where metallic touches occur, at the same time ensuring lubrication properties be, and this overall is the main reason that the chain according to the invention is maintenance-free is.

Ein weiterer Vorteil der Kette gemäß der Erfindung ist, dass in den Innenraum der Buchse keine Verunreinigungen hineingelangen können, da die über die Innenlaschen hinausstehenden Buchsen, die an ihren Stirnseiten an den Außenlaschen anliegen, einen Eintritt von Schmutz und dergl. in den Innenraum wirksam verhindern.One Another advantage of the chain according to the invention is that in the interior of the socket no impurities enter can, because the over the inner tabs protruding sockets, at their front ends on the outer straps abut, entry of dirt and the like. Into the interior effectively prevent.

Nach einer besonderen Ausführungsform der Erfindung können die Buchsen selbst in Edelstahl hergestellt werden und mit einer Oberflächenbeschichtung versehen sein, hier bietet sich Hartverchromen, galvanisch Vermickeln und dergl. an.To a particular embodiment of the Invention can The jacks themselves are made in stainless steel and with a surface coating Be provided, here offers itself Hartverchromen, galvanic Vermickeln and the like.

Es liegt im Rahmen der Erfindung, die Kette so auszugestalten, dass sie in Temperaturbereichen zwischen –20 bis 150°C einerseits und –30 bis 300°C eingesetzt werden können.It is within the scope of the invention, the chain in such a way that in temperature ranges between -20 to 150 ° C on the one hand and -30 to 300 ° C used can be.

Das Prinzip der vorliegenden Erfindung lässt sich bei Einfachketten, aber auch bei Doppel- oder Mehrfachketten entsprechend einsetzen.The Principle of the present invention can be used in single chains, but also for double or multiple chains use accordingly.

Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The Invention will be explained below with reference to the drawing, for example.

Die einzige Figur der Zeichnung zeigt eine Draufsicht auf eine Rollen- bzw. Stahlgelenkkette gemäß der Erfindung.The single figure of the drawing shows a plan view of a roller or steel hinge chain according to the invention.

In der Fig. sind insgesamt vier Innenlaschen gezeigt, die über zwei Außenlaschen 5 miteinander verbunden sind. In einem Teil der Darstellung sind die einzelnen Elemente im Schnitt gezeigt und dort ist der Kettenbolzen 2 zu erkennen, der die beiden Außenlaschen 5 miteinander verbindet. Den Kettenbolzen 2 umgibt ein Polymer-Gleitlager 11 aus selbstschmierendem Material. Die äußere Buchse 1 ist mit den Innenlaschen 4 verbunden und hat über die beiden Innenlaschen 4 hinausgehend zu beiden Seiten einen Überstand. An der Stirnfläche der Buchse 1 liegen die Außenlaschen 5 auf.In the figure, a total of four inner plates are shown, the two outer straps 5 connected to each other. In a part of the illustration, the individual elements are shown in section and there is the chain pin 2 to recognize the two outer plates 5 connects with each other. The chain bolt 2 surrounds a polymer plain bearing 11 made of self-lubricating material. The outer socket 1 is with the inner straps 4 connected and has over the two inner straps 4 going out on both sides of a supernatant. At the end face of the socket 1 are the outer plates 5 on.
