Description
Man hat bereits vorgeschlagen, im Maschinenbau für die Lagerung rotierender Wellen Lagerbuchsen aus Graphit anzuwenden. Die Anwendung von Graphit für diese Zwecke kommt beispielsweise dann in Frage, wenn die bekannten Lagermetalle wegen ihrer Angreifbarkeit durch Chemikalien nicht verwendbar sind oder wenn Buchsen aus chemisch widerstandsfähigen Kunststoffen wegen ihrer Neigung zum Schrumpfen oder Quellen nicht befriedigen. Graphit ist nun zwar frei von diesen Nachteilen, besitzt aber eine den Anforderungen oft nicht genügende Dehnbarkeit. Auch wenn man die Graphitbuchse mit einem Metallfutter umschließt, wird sie als Lager in einer unter Gas- oder Flüssigkeitsdruck arbeitenden Kolbenmaschine leicht zersprengt.It has already been proposed in mechanical engineering for the storage of rotating Shaft bearing bushes made of graphite apply. The application of graphite for this Purpose comes into question, for example, when the known bearing metals because of their vulnerability to chemicals are not usable or if sockets are made chemically resistant plastics because of their tendency to shrink or Sources do not satisfy. Graphite is now free from these disadvantages but an extensibility which is often insufficient for the requirements. Even if you have the graphite bushing Enclosed with a metal lining, it is used as a bearing in a gas or liquid pressure working piston engine easily burst.
Es wurde nun gefunden, daß Graphit oder graphitierte Kohle auch für die Lagerung unter Druck arbeitender Kolben oder Wellen gut geeignet ist, wenn man das Metallfutter, das den Graphitkörper umschließt, mit druckausgleichenden Aussparungen versieht, so daß Graphitkörper und Metallfutter von dem gleichen Druck umgeben sind.It has now been found that graphite or graphitized carbon can also be used for the storage of pistons or shafts working under pressure is well suited if one the metal lining that surrounds the graphite body with pressure-equalizing recesses provided so that the graphite body and metal lining are surrounded by the same pressure.
Eine Ausführungsform einer derartigen Lageruni; ist in der Zeichnung beispielsweise veranschaulicht. Der Pumpenkörper A (Fig. i), in dem sich der Pumpenkolben bewegt, enthält die aus Graphit oder Graphitkohle hergestellte Buchse 13, die von dem Metallfutter C umgeben ist. Dieses Metallfutter ist, wie aus Fig. 2 deutlicher ersichtlich ist, an seinem Umfang mit Aussparungen D versehen. Solche Aussparungen sind auch an der auf der Druckseite der Pumpe liegenden Stirnfläche angebracht (vgl. D1). Eine derartige Graphitlagerung besitzt eine Lebensdauer, die das Mehrfache der Lebensdauer einer gleichartigen, aber mit Metallfutter ohne Aussparungen versehenen Graphitbuchse aufweist.An embodiment of such a storage unit; is in the drawing for example illustrated. The pump body A (Fig. I), in which the pump piston moves, contains the sleeve made of graphite or graphite carbon 13, which of the metal chuck C is surrounded. This metal lining is, as shown in FIG. 2, more clearly can be seen, provided with recesses D on its circumference. Such recesses are also attached to the face on the pressure side of the pump (cf. D1). Such a graphite bearing has a service life that is several times as long the service life of a similar one, but with a metal lining without recesses Has graphite bushing.
