Description

Die Walzgerüste von kontinuierlichen Walzwerken, von denen die Erfindung ausgeht, weisen einen Eintrieb in das Walzgerüst und Kegelradantriebe auf, bei denen sich die Kegelräder, die auf den in zwei Lagerstegen des Gerüstgehäuses abgestützten Walzenwellen angeordnet sind, paarweise in geschlossenen Gehäusen befinden. Diese Gehäuse sind durch Stegwände, die sie auf der Walzenseite abschließen und die all der Durchdringungsstelle der Walzenwellen besondere- Dichtmittel aufweisen, gegen Eindringen von Zunder und `'Nasser geschützt. Die Dichtmittel schützen gleichzeitig auch die Lager gegen Zunder und Wasser.The rolling stands of continuous rolling mills, of which the invention goes out, have an input into the roll stand and bevel gear drives, in which the bevel gears, which are supported on the two bearing bars of the scaffold housing Roller shafts are arranged, located in pairs in closed housings. These Housings are through web walls that close them on the roller side and which all the penetration point of the roller shafts have special sealants against Penetration of scale and '' wet protected. The sealants protect at the same time also the bearings against tinder and water.

Bei einer Ausführungsart von derartigen Walzgerüsten sitzen die Stegwände unmittelbar beidseits der Walzen; die Kegelräder sind auf den Walzenwellen fliegend am Wellenende angeordnet. Dadurch ist es möglich, sie schmutzsicher in den ölgefüllten Gehäusen unterzubringen. Bei einer anderen Ausführungsart, die gedrängter baut, sitzen die Kegelräder neben den Walzen, und die Walzenwellen sind an ihren Enden in den Stegwänden abgestützt. Hierdurch sind die Stegwände von den Walzen weit abgerückt und sitzen hinter den Kegelrädern. Die Abdichtung, die bei der erstgenannten Ausführungsart durch die Stegwände gegeben ist, besteht bei dieser zweitgenannten Ausführungsart nicht. Die Kegelräder sitzen dort vielmehr unmittelbar neben den Walzen und sind. dem Angriff von Zunder und Wasser ausgesetzt.In one embodiment of such roll stands, the web walls are seated immediately on both sides of the rollers; the bevel gears are overhung on the roller shafts arranged at the shaft end. This makes it possible to keep them dirt-proof in the oil-filled To accommodate housings. In another type of construction that is more compact, the bevel gears sit next to the rollers, and the roller shafts are at their ends supported in the web walls. As a result, the web walls are far removed from the rollers and sit behind the bevel gears. The seal that is used in the first-mentioned embodiment is given by the web walls, exists in this second embodiment not. Rather, the bevel gears sit there directly next to the rollers and are. exposed to the attack of scale and water.

Um auch bei der zweitgenannten Ausführungsart eine schmutzsichere Unterbringung der Kegelräder in einem Gehäuse zu erreichen, sind nach der Lehre der Erfindung die Walzenwellen in bekannter Weise an ihren. Enden abgestützt, ferner die walzenseitigen Stegwände als reine Dichtungsstege ausgebildet und die Gehäuse nunmehr gemeinsam von den Lagerstegen und von, den Dichtungsstegen gebildet.In order to also have a dirt-proof in the second-mentioned embodiment Accomodation of the bevel gears in a housing are to be achieved according to the teaching of the invention, the roller shafts in a known manner on their. Ends supported, furthermore the roll-side web walls are designed as pure sealing webs and the housing now formed jointly by the bearing bars and by the sealing bars.

Der Gegenstand der Erfindung ist in den Abb. i und 2 im Querschnitt und im Schnitt nach der Linie A-A der Abb. i dargestellt.The object of the invention is shown in Figs. I and 2 in cross section and shown in section along the line A-A of Fig. i.

Die Eintriebswelle i, auf der die Kegelräder 2 und 3 und die Walze 4 sitzen, ist im Walzgerüstgehäuse 5 mit Hilfe der Lager 6 und 7 gelagert. Die Kegelräder 2 und 3 treiben die Kegelräder 8 und 9 an, die mit Hilfe von Naben io und ii mit den Walzen i2 und 13 fest verbunden sind. Die Kegelräder 8 und 9 mit den Naben io und i i und die Walzen 12 und 13 sind mit Hilfe der Lager 14 und 15 auf den Walzenachsen 16 und 17 gelagert, die wiederum undrehbar und unverschieblich im Walzgerüstgehäuse 5 gelagert sind. Die Walzenachsen 16 und 17 haben schräge Kanten 18 und i9, um die Lagerungen 6 und 7 in geeigneter Weise ausführen zu können. Zwischen den Walzen 4, 12, 13 und den Kegeltrieben 2, 3, 8, 9 sind Labyrinthdichtungen 2o in den Stegen 21 angeordnet, die verhindern, daß der beim Walzen abfallende Zunder in die Kegelgetriebe gerät, und die ungefähr parallel zu den Lagerstegen 22 verlaufen.The input shaft i, on which the bevel gears 2 and 3 and the roller 4 is seated in the roll stand housing 5 with the help of bearings 6 and 7. The bevel gears 2 and 3 drive the bevel gears 8 and 9, which with the help of hubs io and ii the rollers i2 and 13 are firmly connected. The bevel gears 8 and 9 with the hubs io and i i and the rollers 12 and 13 are with the help of the bearings 14 and 15 on the roller axles 16 and 17 mounted, which in turn cannot be rotated and cannot be displaced in the roll stand housing 5 are stored. The roller axles 16 and 17 have inclined edges 18 and i9 to the To be able to carry out bearings 6 and 7 in a suitable manner. Between the rollers 4, 12, 13 and the bevel drives 2, 3, 8, 9 are labyrinth seals 2o in the webs 21 arranged, which prevent the falling scale during rolling into the bevel gears device, and which run approximately parallel to the bearing webs 22.
