Description
LAGERUNG DER BRENNWALZEN DURCH BEIDERSEITIGE STÜTZWALZENSUPPORTING ROLLERS BY DOUBLE-SIDED SUPPORT ROLLERS
ZWECKS VERRINGERUNG DES AUFLAGEABSTANDES. FOR THE PURPOSE OF REDUCING THE SPACE.
Boden- und Wandplatten und ähnliche keramische Erzeugnisse werden zur Zeit in Rollenherdöfen gebrannt. Runde Rohre = Brennwalzen durchdringen die entsprechenden Öffnungen in den Seitenwänden des Ofens und sind in Lagern der äußeren Seitenwände auf Rundlauf angetrieben. Die Lagerstellen der Brennwalzen haben durch die Dicke der Ofenwand und den Abstand der Lager von der Ofenwand einen großen Abstand im Verhältnis zur inneren Nutz-Breite des Ofens. Die Brennwalzen werden hoch erwärmt, 2 bis die Festigkeit nur noch wenige Gramm/mm2 beträgt.Floor and wall tiles and similar ceramic products are used currently fired in roller hearth furnaces. Round tubes = burn rollers penetrate the corresponding openings in the side walls of the furnace and are in bearings of the outer Side walls driven on concentricity. The bearings of the burn rollers have through the thickness of the furnace wall and the distance between the bearings and the furnace wall a large distance in relation to the internal usable width of the furnace. The burn rollers are heated to a high 2 until the strength is only a few grams / mm2.
Die Brennwalze biegt sich durch und führt in diesem gebogenen Zustand die Drehung durch, wobei die Elastizität des hitzebeständigen Stahles im höchsten Maß beansprucht ist.The burning roller bends and leads in this bent state the rotation by, whereby the elasticity of the heat-resistant steel in the highest Degree is claimed.
Das Biegemoment der Brennwalze kann wesentlich verringert werden, wenn ihr Auflageabstand verringert wird und die Brennwalze wenig mehr Länge als die innere Ofenbreite hat.The bending moment of the burning roller can be reduced significantly, if their support distance is reduced and the burning roller is a little longer than has the inner width of the oven.
Mein Vorschlag zur Entlastung der Brennwalze ist, die Brennwalze kurz hinter der inneren Ofenwand beiderseits durch angetriebene Stützwalzen zu tragen und zu drehen.My suggestion for relieving the burn roller is to short the burn roller to be carried behind the inner furnace wall on both sides by driven support rollers and turn.
Die Brennwalze liegt dann mit ihren Bohrungsenden auf den Zapfen der Stützwalzen.The focal roller then lies with its bore ends on the journal of the Backup rolls.
In den beiliegenden Zeichnungen ist mein Vorschlag dargestellt: Fig. 1 stellt den Ofen 1 mit Innenraum 2, der Brennwalze 3, Stützwalzen 4, Glühgut 7, dar.My suggestion is shown in the accompanying drawings: Fig. 1 represents the furnace 1 with interior 2, the firing roller 3, support rollers 4, annealing material 7, represent.
Die Stützwalzen 4 liegen in den Lagern 8 und 8'. The backup rollers 4 are in the bearings 8 and 8 '.
Durch die Ketten 10 sind die Kettenräder 9 und 14 und die Welle 11 verbunden, so daß die Stützwalzen 4 gleichmäßig angetrieben sind. Through the chains 10, the sprockets 9 and 14 and the shaft 11 are connected so that the backup rollers 4 are driven uniformly.
Zur Wahrung der axialen Übereinstimmung von Brennwalze 3 und Stützwalzen 4 sind die Lager 8 und 8' durch die Pfeiler 12 und den Querbalken 13 verbunden. To maintain the axial correspondence of the focal roller 3 and the backup rollers 4, the bearings 8 and 8 'are connected by the pillars 12 and the crossbeam 13.
Die Verbindungsstelle = Kupplung der Stützwalze 4 mit Brennwalze 3 ist in Fig. 2 dargestellt. The connection point = coupling of the support roller 4 with the burning roller 3 is shown in FIG.
In die Bohrung 6 der Ofenwand 19 ragt die Stützwalze 4 mit dem Zapfen 5 in die Brennwalze 3 mit Endstück 18. Die Zapfen 5 haben die balligen Enden 17 und treiben die Brennwalze 3 an. Das Brennwalzen-Ende 18 und entsprechend das Stützwalzen-Ende 17 können verzahnt sein. In the bore 6 of the furnace wall 19, the support roller 4 protrudes with the pin 5 in the burning roller 3 with end piece 18. The pins 5 have spherical ends 17 and drive the focal roller 3. The burning roller end 18 and correspondingly the back-up roller end 17 can be interlocked.
Etwa im Bereich der inneren Ofenwand 19 und vor dem Walzenende 18 sind die Scheiben 15 und 14, zwischen denen sich die Isolier-Füllung 16 befindet.Approximately in the area of the inner furnace wall 19 and in front of the end of the roll 18 are the discs 15 and 14, between which the insulating filling 16 is located.
Die Brennwalze 3 liegt mit ihren Endstücken 18 auf den ballig geformten Enden 17 der Zapfen 5. Das Endstück 18 der Brennwalze 3 kann die zylindrische Verzahnung entsprechend der Verzahnung des balligen Zapfenendes 17 haben.The focal roller 3 lies with its end pieces 18 on the spherically shaped Ends 17 of the pin 5. The end piece 18 of the burning roller 3 can have the cylindrical toothing have corresponding to the toothing of the spherical pin end 17.
Durch die Antriebsverbindung von Kettenrädern 9 und 14 mit Ketten 10 und Welle 11 stimmen die Drehungen der Stützwalzen 4 überein und übertragen diese auf die Brennwalze 3 mit Walzenende 18, wobei diese ihre Wärmedehnung in axialer Richtung ausführen kann, weil das Längsspiel 20 entsprechend groß ist.Through the drive connection of sprockets 9 and 14 with chains 10 and shaft 11 match the rotations of the support rollers 4 and transmit them on the focal roller 3 with the roller end 18, with this its thermal expansion in axial Can run direction because the longitudinal play 20 is correspondingly large.
Durch den Einbau der Scheiben 14 und 15 mit Isoliermaterial 16 wird das Walzenende 18 in der Temperatur herabgesetzt, was zur Genauigkeit der Kupplung beiträgt.By installing the disks 14 and 15 with insulating material 16 is the roller end 18 lowered in temperature, resulting in the accuracy of the coupling contributes.
Die Lagerung der Brennwalzen 3, 18 im Bereich der Ofenwand 19 bringt einen geringeren Auflageabstand und damit das kleinere Widerstandsmoment für ihre Durchbiegung und Haltbarkeit. Die Haltbarkeit der Brennwalzen (3, 18) ist ausschlaggebend für die Wirtschaftlichkeit des Ofens.The storage of the firing rollers 3, 18 in the area of the furnace wall 19 brings about a smaller support distance and thus the smaller section modulus for your Deflection and durability. The durability of the burn rollers (3, 18) is crucial for the profitability of the furnace.
Die Übertragung der Drehung der Stützwalzen 4 auf die' Brennwalze 3, 18 ist in der geschilderten Weise mechanisch dargestellt. Die Übertragung kann in einfacherer Weise elektrisch durch Synchron-Motoren vorgenommen werden.The transmission of the rotation of the backup rollers 4 to the 'burning roller 3, 18 is shown mechanically in the manner described. The transfer can can be made in a simpler way electrically by synchronous motors.
