Description
Die Erfindung betrifft eine Vorrichtung zum Schütze von Achsen einer Antriebsvorrichtung, die in angreifenden Behandlungsbädern liegen, insbesondere bei Viskosefilmgießmaschinen. Sie besteht darin, daß auf der Walzenstirnfläche und an der Gefäßwand oder einem an dieser befestigten Gußkörper senkrecht zur Walzenachse Ringscheiben aus Glas oder anderem den in Frage kommenden Flüssigkeiten widerstehendem Material angeordnet sind, die fest gegeneinander gepreßt werden. The invention relates to a device for protecting axles of a drive device, which lie in attacking treatment baths, especially in the case of viscose film casting machines. It consists in that on the roller face and on the vessel wall or a cast body attached to this, perpendicular to the roller axis, ring disks made of glass or other material resistant to the liquids in question that are pressed tightly against each other.
Auf der Zeichnung ist die Vorrichtung im Querschnitt dargestellt.In the drawing, the device is shown in cross section.
Die Antriebswelle 1 einer Filmgießwalze durchdringt die Seitenwände 2 des Gießtroges, dessen Innenwände, wie überhaupt alle diejenigen Teile, die nicht in gleitender Reibung aufeinander arbeiten, in der üblichen Weise, z. B. durch Gummiüberzug, vor dem Angriff der in Anwendung kommenden Flüssigkeiten hinreichend geschützt werden.The drive shaft 1 of a film casting roll penetrates the side walls 2 of the casting trough, its inner walls, like all those parts in general, which do not work on one another in sliding friction, in the usual way Way, e.g. B. by rubber coating, before the attack of the liquids in use be adequately protected.
Auf einer der seitlichen Stirnflächen 3 der Gießwalze ist ein Ring 4 angegossen, in den «5 eine ringförmige Scheibe S eingepaßt wird, die aus Glas oder keramischem Material besteht. On one of the lateral end faces 3 of the casting roll, a ring 4 is cast into which «5 an annular disc S is fitted, which consists of glass or ceramic material.
Die Abdichtung nach außen erfolgt durch den Gußkörper 6, der an die Gefäßwand 2, die an dieser Stelle, etwa durch einen aufgelegten Ring 7, verstärkt ist, angeschraubt wird. Auf der Außenseite ist dieser Gußkörper zu der üblichen Stopfbüchse ausgestaltet, welche aus dem Topf 8 und der mit Hilfe der Schrauben 9 nachstellbaren Brille 10 besteht.The seal to the outside is made by the cast body 6, which is attached to the vessel wall 2, which is reinforced at this point, for example by an applied ring 7, screwed on will. On the outside, this cast body is designed to form the usual stuffing box, which consists of the pot 8 and the glasses 10, which can be adjusted with the aid of the screws 9.
Auf der Innenseite hingegen bildet der Körper 6 durch den Ringwulst 11 eine Vertiefung, in welche eine ringförmige Platte 12 aus Glas oder keramischem Material paßt. Diese wird durch Vermittelung des dahinter liegenden Gummiringes 13 in elastischer WeiseOn the inside, however, the body 6 forms a recess through the annular bead 11, in which an annular plate 12 made of glass or ceramic material fits. This is made by means of the rubber ring 13 located behind it in an elastic manner
fest gegen die Platte 5 angedrückt. Die Stifte 14 verhindern hierbei ein Mitdrehen der beiden Scheiben 5 und 12.pressed firmly against the plate 5. The pencils 14 prevent the two disks 5 and 12 from rotating at the same time.
Bei der Vorrichtung ist also die eigentliche Trenn- und Abdichtungsfläche zwischen Gießwalze und Gefäßwand in die senkrecht zur Achse stehende Ebene a-b verlegt. An Stelle des sonst als Abdichtungsfläche üblichen Zylindermantels (Stopfbüchse) wird hier durch das Gegeneinanderpressen der beiden ringförmigen Scheiben 5 und 12 (z. B. mattgeschUffene Glasplatten) ein absolut dichter Abschluß erreicht, ohne daß auch nur das geringste Stück der Welle 1 mit der Badflüssigkeit in Berührung kommt.In the apparatus therefore, the actual cutting and sealing surface between the casting roll and the vessel wall in the plane perpendicular to the axis is moved from. Instead of the cylinder jacket (stuffing box) which is otherwise used as a sealing surface, an absolutely tight seal is achieved here by pressing the two ring-shaped disks 5 and 12 against each other (e.g. frosted glass plates) without even the slightest piece of shaft 1 containing the bath liquid comes into contact.
In dem zwischen den Scheiben 5 und 12 und der Welle 1 vorhandenen Ringkanal wird eine mit Öl durchtränkte Textilpackung 15 eingelegt. Durch eine Bohrung, etwa durch den Kanal 16, steht dieser Raum mit einem öler 17 in Verbindung. Dieser führt das Schmiermittel mit einem Druck zu, der etwas größer ist als der Druck, den das Fällbad im Gießtrog ausübt. Auf diese Weise gelangt das Schmiermittel auch zwischen die Reibflächen 5 und 12, so daß der angreifende Inhalt des Gießtroges dort nicht eindringen kann.In the ring channel present between the disks 5 and 12 and the shaft 1 is a textile packing 15 impregnated with oil is inserted. Through a hole, for example the channel 16, this space is connected to an oiler 17. This one does that Lubricant with a pressure that is slightly greater than the pressure in the precipitation bath Watering trough exercises. In this way, the lubricant also gets between the friction surfaces 5 and 12, so that the aggressive contents of the pouring trough do not penetrate there can.
