Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf einen anorganischen Lagerwerkstoff, bei dem von den Gleiteigenschaften des Titandisulfids, Ti S2, Gebrauch gemacht wird.The invention relates to an inorganic bearing material in which use is made of the sliding properties of titanium disulfide, Ti S 2.
Es ist bereits bekannt, Graphit oder Molybdändisulfid zur Verbesserung der Gleiteigenschaften sich reibender Metallflächen anzuwenden bzw. damit einen Notlauf von Lagern zu ermöglichen. Zu diesem Zweck wird entweder dem Schmieröl Graphit oder Molybdändisulfid beigegeben, oder Graphit bzw. Molybdändisulfid wird als Paste oder in anderer Weise auf die Oberfläche der sich reibenden Teile gebracht. Weiter sind Schmiermittel aus organischen Flüssigkeiten mit Zusätzen von Molybdändisulnd, Titandisulfid od. dgl. bekannt. Es ist auch bekannt, aus Metall bestehende Lager chemisch so zu behandeln, daß mindestens auf der Lageroberfläche der Lagerwerkstoffe Molybdändisulfid enthalten ist. Man hat ferner auch Molybdändisulfid vor dem Guß des Lagers in den Lagerwerkstofr eingebracht. Es sind auch Lager, Kolben od. dgl. mit Titanlaufflächen bekanntgeworden. Schließlich ist nicht nur das Erzeugen von Titanüberzügen, sondern auch das Aufbringen von Titandio'xydüberzügen bekannt. It is already known graphite or molybdenum disulfide to improve the sliding properties of rubbing metal surfaces or to use one To enable emergency running of bearings. For this purpose, either graphite or molybdenum disulfide is used in the lubricating oil added, or graphite or molybdenum disulfide is added as a paste or in some other way to the Brought surface of the rubbing parts. Next are lubricants made from organic liquids with Additions of molybdenum disulfide, titanium disulfide or the like. known. It is also known to treat existing metal bearings chemically so that at least on the bearing surface of the bearing materials contains molybdenum disulfide. Molybdenum disulfide is also used before casting the bearing into the bearing material brought in. Bearings, pistons or the like with titanium running surfaces have also become known. Finally is not only the production of titanium coatings, but also the application of titanium dioxide coatings is known.
Aufgabe der Erfindung ist es, einen Lagerwerkstoff zu schaffen, der Selbstschmiereigenschaften aufweist. Es gibt Fälle, in denen sich das hohe spezifische Gewicht des an sich gut schmierenden Molybdändisulfids entweder im Betrieb selbst oder aber bei der Herstellung wegen der starken Abweichung von den spezifischen Gewichten der anderen gleichzeitig zur Ver-Wendung gelangenden Werkstoffe ungünstig auswirkt. Hier schafft die vorliegende Erfindung Abhilfe.The object of the invention is to create a bearing material that has self-lubricating properties. There are cases in which the high specific weight of molybdenum disulphide, which is inherently well lubricating, has a negative effect either in the company itself or in the production process because of the strong deviations from the specific ones Weighting the other materials used at the same time has an unfavorable effect. The present invention provides a remedy here.
Der anorganische Lagerwerkstoff nach der vorliegenden Erfindung ist dadurch gekennzeichnet, daß er einenZusatz von Titandisulfid enthält. Infolge seines hohen Schmelzpunktes von über 1000° C eignet sich Titandisulfid als Zusatz zu metallischen und/oder nichtmetallischen anorganischen, z. B. o>xyd-, metallsulfide metallphosphid- oder mischkeramischen Lagerwerkstoffen. Es ist ohne weiteres möglich, Titandisulfid Bronzelagern und Lagern aus anderen Lagermetallen bei der Herstellung unmittelbar zuzusetzen, weil, sofern die Schmelztemperatur des Disulfidzusatzes dabei nicht überschritten wird, seine Gleiteigenschaften erhalten bleiben und der gleitfähige Zusatz infolge der gleichmäßigen Verteilung im Werkstoff auch bei Abnutzung während langer Betriebsdauer jederzeit zur Verfügung steht. Der Lagerwerkstoff gemäß der Erfindung hat also Selbstschmiereigenschaften. Die gute Gleitfähigkeit des Titandisulfids beruht auf der zu Schuppenform neigenden Ausbildung der Teilchen und hängt mit der hexagonalen Kristallstruktur dieser Verbindung zusammen. The inorganic bearing material according to the present invention is characterized in that it contains an addition of titanium disulfide. As a result of his With a high melting point of over 1000 ° C, titanium disulfide is suitable as an additive to metallic and / or non-metallic inorganic, e.g. B. o> xyd, metal sulfide, metal phosphide or mixed ceramic bearing materials. It is easily possible to use titanium disulfide bronze bearings and bearings made from other bearing metals to be added immediately during production because, provided that the melting temperature of the disulfide addition is not exceeded, its sliding properties are retained and the slippery Addition as a result of the even distribution in the material, even with wear and tear during long periods of operation is available at all times. The bearing material according to the invention thus has self-lubricating properties. The good sliding properties of titanium disulfide are based on its tendency to flake Formation of the particles and is related to the hexagonal crystal structure of this compound.

Der Lagerwerkstoff gemäß der Erfindung kann unter anderem auch durch Sinterung hergestellt werden. Besonders vorteilhaft ist die Beigabe von Titandisulfid zu Sinterkörpern für Lagerungen und Gleitflächen, weil bei diesem Verfahren eine besonders gleichmäßige Vermischung des Disulfidzusatzes mit den anderen Bestandteilen möglich ist und außerdem die Sintertemperatur ein Schmelzen der Bestandteile überflüssig macht.The bearing material according to the invention can, inter alia, also be produced by sintering. The addition of titanium disulfide to sintered bodies for bearings and sliding surfaces is particularly advantageous, because in this process a particularly uniform mixing of the disulfide additive with the other constituents is possible and also the sintering temperature a melting of the constituents makes redundant.
Die Beigabe des Titandisulfids zu den vorgenannten anorganischen für Lager geeigneten Werkstoffen kann bis zu 25 Volumprozent, aber auch mehr betragen. Vorteilhaft werden etwa 3 bis 15 Volumprozent beigegeben. The addition of the titanium disulfide to the aforementioned inorganic materials suitable for bearings can up to 25 percent by volume, but also more. It is advantageous to add about 3 to 15 percent by volume.
Die Figur zeigt zur Erläuterung des Erfindungsgegenstandes z. B. eine Welle 1, die in einem Lager 2 innerhalb des auf dem Lagerfuß 3 sitzenden Lagergehäuses 4 angeordnet ist. Das Lager 2 aus anorganischem Werkstoff enthält Titandisulfid, so daß bei einer Abnutzung des Lagers den Laufflächen zur Niedrighaltung der Reibung stets Sulfid zugeführt wird.The figure shows to explain the subject matter of the invention, for. B. a shaft 1 which is arranged in a bearing 2 within the bearing housing 4 seated on the bearing foot 3. The bearing 2 made of inorganic material contains titanium disulfide, so that when the bearing is worn, sulfide is always fed to the running surfaces in order to keep the friction low.
Die Erfindung ermöglicht es, Lager aus anorganischen Stoffen ohne jede Schmierung mittels eines Öles oder Fettes od. dgl., vor allem auch bei sehr hohen Temperaturen, wie sie z. B. bei Drehstrommotoren mit Silikonisolation oder Gasturbinen oder Röntgenröhren mit rotierender Anode auftreten können, zu verwenden. The invention enables bearings made of inorganic materials without any lubrication by means of an oil Or fat or the like, especially at very high temperatures, such as those found in B. with three-phase motors Silicone insulation or gas turbines or X-ray tubes with rotating anodes can occur.
Es ist auch möglich, einen anorganischen Lagerwerkstoff mit Zusätzen von Titandisulfid und Molybdändisulfid herzustellen.It is also possible to use an inorganic bearing material with additions of titanium disulfide and To produce molybdenum disulfide.
