Description
Selbstdichtendes Gleitlager. Kunstkohle eignet sich bekanntlich wegen ihrer hervorragenden Eigenschmierfähigkeit, ihrem hohen Wärmeableitvermögen und ihrer geringen mechanischen Abnützung sehr gut als Gleitlagervwerkstoff. Es sind zahlreiche Fälle aus der Praxis, insbesondere aus der Glas-, Keramik- und Hüttenindustrie be kannt, bei welchen zylindrische Kunstkohle lagerbüchsen eine erheblich längere Lebens dauer als metallische Gleitslagerbüehsen zu verzeichnen hatten.
Um diese vorteilhafte Anwendung der Kunstkohle auch auf solche Gleitlager über tragen zu können, die neben ihrer tragenden eine abdichtende Funktion haben sollen, musste ein neuer Weg beschritten werden, um Wellenträger und Dichtmittel zu vereinen.
Die vorliegende Erfindung betrifft ein selbstdichtendes Gleitlager, dessen Lager biichse mindestens zum Teil aus Kunstkohle besteht. Sie ist dadurch gekennzeichnet, dass die Dichtungselemente aus verformbaren Ab dichtungsstoffen in Nuten des Kunstkohle Lagerbüchsenteils verlegt sind. .Vorteilhaft werden durch ein nachträglich eingebrachtes Imprägnier- und Verbundmittel die Abdich tungsmittel mit dem Kunstköhlelagerbüchsen- teil Das Verbundmittel wird da; bei zweckmässig so gehalten, dass es die dich tenden Eigenschaften des Lagerkörpers und seiner Dichtmedien fördert und unterstützt.
Als Dichtmittel können 'je nach Verwen dungszweck Filz, Hanf- und Gummigewebe oder gleichartige, plastisch bzw. _ elastisch ver formbare Abdichtungsstoffe mit rundem, quadratischem oder dreieckigem Profil in Be tracht kommen. Zweckmässig werden ge nannte Dichtungselemente vor der Imprägnie rung in ring- oder spiralenförmige Nuten des Kohlelagerkörpers durch Einlegen, Einpres sen oder Einkitten so fixiert, dass die aus der Bohrung des Kohlelagers hervorstehenden Teile der Dichtungsringe gegenüber dieser Bohrung ein Untermass aufweisen, welches bis zum dreifachen Wert des vorgesehenen Wellenspiels erreichen kann.
Die Anzahl der einzulegenden Dichtungs elemente kann 1, 2 oder mehr betragen. Sie richtet sich, ebenso wie die Einbaustellen der Dichtungselemente innerhalb des Gleitlager körpers, weitgehend nach den jeweiligen Be triebserfordernissen.
A:bb.1 und 2 der Zeichnung zeigen bei spielsweise eine Ausführungsform des Erfin dungsgegenstandes im Längs- und Quer schnitt.
Die Anordnung besteht aus der eigent lichen Lagerbüchse 1 aus Kunstkohle, die zur Erhöhung der mechanischen Festigkeit in eine Stahlhülse 2 gepresst ist. Das zusätz liche Aufbringen dieses metallischen Stütz ringen ist nur in aussergewöhnlichen Bela stungsfällen notwendig; im allgemeinen kann die Lagerbüchse ohne besondere Metallhülse hergestellt werden.
Die Dichtungselemente sind in Form von Filzringen 3 in die nut- artigen Vertiefungen 4 des Lagerkörpers 1 eingepresst und anschliessend durch ein ge- eignetes Imprägnier- und Verbundmittel, z. B. Hartwachs, mit diesem zu einem mecha nisch festen Bauelement zusammengefügt.
Self-sealing plain bearing. Artificial charcoal is known to be very suitable as a plain bearing material because of its excellent self-lubricating properties, its high heat dissipation capacity and its low mechanical wear. There are numerous cases from practice, in particular from the glass, ceramics and metallurgical industry, be known in which cylindrical charcoal bearing bushes had a significantly longer life than metallic sliding bearing bushes.
In order to be able to carry this advantageous application of charcoal to plain bearings that are supposed to have a sealing function in addition to their load-bearing function, a new approach had to be taken to combine shaft carriers and sealants.
The present invention relates to a self-sealing sliding bearing, the bearing of which is at least partly made of synthetic carbon. It is characterized in that the sealing elements made of deformable sealing materials are laid in grooves of the synthetic carbon bearing bush part. The sealing means with the synthetic carbon bearing bush part are advantageous through a subsequently introduced impregnation and bonding agent. The bonding agent is there; if kept appropriately so that it promotes and supports the dense properties of the bearing body and its sealing media.
Depending on the intended use, felt, hemp and rubber fabric or similar, plastic or elastic sealing materials with a round, square or triangular profile can be used as sealing means. Before the impregnation, the sealing elements are appropriately fixed in ring-shaped or spiral-shaped grooves in the carbon bearing body by inserting, pressing or cementing them in such a way that the parts of the sealing rings protruding from the bore of the carbon bearing are undersized compared to this bore, which is up to three times the value the intended shaft clearance can achieve.
The number of sealing elements to be inserted can be 1, 2 or more. Like the installation locations of the sealing elements within the plain bearing body, it is based largely on the respective operating requirements.
A: bb.1 and 2 of the drawing show, for example, an embodiment of the subject of the invention in longitudinal and cross-section.
The arrangement consists of the actual bearing bush 1 made of charcoal, which is pressed into a steel sleeve 2 to increase the mechanical strength. The additional application of this metallic support rings is only necessary in exceptional cases of Bela; In general, the bearing bush can be manufactured without a special metal sleeve.
The sealing elements are pressed into the groove-like depressions 4 of the bearing body 1 in the form of felt rings 3 and then secured by a suitable impregnating and bonding agent, e.g. B. hard wax, joined with this to form a mechanically solid component.
