Description

Temperaturwechselbeständige Verbindung von Werkstoffen mit verschiedenen Ausdehnungskoeffizienten Verbindungen von Werkstoffen mit verschiedenen Ausdehnungskoeffizienten sind bei starken Temperaturwechseln der Gefahr des Reißens ausgesetzt. Um diesen Mängel zu beseitigen, hatte man bereits vorgeschlagen, z. B. die Metallwellen einer Walze aus keramischem Material mittels kegeliger, in entsprechende Hohlkegel der Walzenstirnfiächen passender Scheiben zu befestigen.Thermal shock resistant connection of materials with different Expansion coefficients Connections of materials with different expansion coefficients are exposed to the risk of tearing in the event of strong temperature changes. To this one It had already been proposed to eliminate deficiencies, e.g. B. the metal shafts one Roller made of ceramic material by means of a conical, corresponding hollow cone of the To fasten the roller end faces of suitable disks.

Nach der Erfindung werden die Scheiben unter Federdruck längsverschieblich angeordnet. Die Zeichnung stellt eine Abbildung des Erfindungsgedankens im Längsschnitt dar. Auf der Eisenwelle a sind zu beiden Seiten kegelförmige Zentrierringe r. angeordnet, die durch einen Keil b mit der Welle verbunden sind. Zentrierung und Walze haben genau ineinander passende Kegelflächen d, die gleichzeitig als Auflage dienen. Auf der Eisenwelle a sind -die Muttern e aufgesetzt, die die Federn f gegen die Zentrierringe c drücken. Die Spannkraft dieser Federn ist so bemessen, daß eine genügende Starrheit des Gebildes gewährleistet ist, daß aber bei Temperaturänderungen die praktische Möglichkeit besteht, daß der Ring c durch die Feder stets gegen die Kegelfläche d gepreßt wird, ohne daß die Walze locker oder der Druck so stark wird, daß die Walze bei stärkerer Zusammenziehung reißt. Der Zentrierring c, mit der Welle a durch den Keil b mit Bezug auf die Drehrichtung starr verbunden, läßt ihm aber in der Längsrichtung der Welle einen Spielraum. Um die Feder zu schützen, wird die Öffnung der Walze durch eine Verschlußkappe g aus keramischem Material verschlossen. Die Welle hat ebenfalls in der Durchführungsöffnung noch genügend Ausdehnungsmöglichkeit,. um ein Sprengen zu verhindern. Zur Vermeidung des Eindringens von Flüssigkeiten ist in den Ringmantel eine kreisförmig umlaufende Nut h eingelassen, die mit bekannten Dichtungsmitteln gefüllt werden kann. Das gleiche gilt von den -äußeren Berührungsflächen e er Verschlußkappe.According to the invention, the disks are arranged to be longitudinally displaceable under spring pressure. The drawing shows an illustration of the concept of the invention in longitudinal section. On the iron shaft a, there are conical centering rings r on both sides. arranged, which are connected to the shaft by a key b. Centering and roller have conical surfaces d that fit exactly into one another and also serve as a support. The nuts e that press the springs f against the centering rings c are placed on the iron shaft a. The tensioning force of these springs is such that sufficient rigidity of the structure is ensured, but that when the temperature changes there is the practical possibility that the ring c is always pressed against the conical surface d by the spring without the roller loosening or the pressure so becomes strong that the roller ruptures with greater contraction. The centering ring c, rigidly connected to the shaft a by the wedge b with respect to the direction of rotation, but leaves it a margin in the longitudinal direction of the shaft. To protect the spring, the opening of the roller is closed by a cap g made of ceramic material. The shaft also has enough space for expansion in the lead-through opening. to prevent blasting. To avoid the penetration of liquids, a circular circumferential groove h is let into the ring jacket, which groove can be filled with known sealing means. The same applies to the outer contact surfaces e he closure cap.
