Description
Temperaturwechselbeständige Verbindung von Werkstoffen Besondere Schwierigkeiten machte die Befestigung von Walzen aus keramischem Werkstoff auf Metallwellen, weil die Ausdehnungskoeffizienten der beiden Werkstoffe sich ungefähr wie z : 3 verhalten.Connection of materials resistant to temperature changes. Particular difficulties made the attachment of rollers made of ceramic material on metal shafts because the expansion coefficients of the two materials are roughly z: 3.
Der Grundgedanke der Erfindung ist der, die Welle mit der Walze in üblicher Weise an sich vollkommen dicht und starr zu verbinden und den Ausgleich der durch,die Temperaturschwankungen bedingten, verschieden großen Ausdehnungen innerhalb der Walze dadurch stattfinden zu lassen, daß man nicht eine Welle aus einem Stück verwendet, sondern zwei Wellenenden, die teleskopartig ineinandergesteckt werden und sich unter dem Einfluß der Temperaturschwankungen ineinander verschieben können, gewissermaßen zwei nach innen so verlängerte Zapfen, daß sie sich längs verschieblich gegenseitig abstützen. Hierbei wird eine vollkommene Abdichtung des Walzeninnern gegen außen an den Wellenenden ermöglicht und ein unerwünschtes Eindringen von Flüssigkeit in das Walzeninnere vermieden. Die geringen Schwankungen des Luftdrucks innerhalb der Walze werden von dem keramischen Walzenkörper ohne weiteres aufgenommen.The basic idea of the invention is that the shaft with the roller in usual way to connect completely tightly and rigidly and the balance the expansion caused by the temperature fluctuations of different sizes to take place inside the roller so that you do not get a wave from it one piece, but two shaft ends that are telescopically nested and shift into one another under the influence of temperature fluctuations can, as it were, two inwardly elongated pegs that they extend lengthways support each other displaceably. This is a complete seal of the Roll inside against outside at the shaft ends and allows unwanted penetration of liquid into the interior of the roller is avoided. The small fluctuations in air pressure inside the roller are easily received by the ceramic roller body.
Ein Ausführungsbeispiel der temperaturwechselbeständigen Verbindung mach der Erfindung ist in der Abbildung dargestellt. In dieser sind a, und a; die beiden Wellenteile (Zapfen), die teleskopartig sich bei b ineinander verschieben. Die beiden Wellenhälften sind durch die Ringe c, erforderlichenfalls noch unter Zwischenschaltung eines Dichtungsringes cl, der die geringen Ausdehnungsschwankungen des beiderseitig angeordneten keramischen Auflagers d aufnimmt, auf diesem und damit auf der Walze w befestigt. Um eine vollkommene Abdichtung der Welle gegen die Walze zu erzielen, werden nach ausgeführter Befestigung die beiden Walzenenden zweckmäßig mit einem korrosionsbeständigen Material ausgefüllt.An embodiment of the temperature change resistant connection Mach the invention is shown in the figure. In this are a, and a; the two shaft parts (journals) that slide telescopically into one another at b. The two halves of the shaft are through the rings c, if necessary still under Interposition of a sealing ring cl, which reduces the small expansion fluctuations of the ceramic support d arranged on both sides takes up, on this and thus attached to the roller w. To ensure a perfect seal between the shaft and the roller to achieve, the two ends of the roller are expedient after the fastening has been carried out filled with a corrosion-resistant material.
Die Verbindung ist nicht auf keramische Walzen beschränkt, sondern überall da möglich und anwendbar, wo Walzen auf Wellen mit unterschiedlichem Ausdehnungskoeffizienten befestigt werden sollen.The connection is not limited to ceramic rollers, but rather Possible and applicable wherever rollers on shafts with different expansion coefficients should be attached.
