Description

DEUTSCHESGERMAN

Es sind Gerüste für Undversalwalzwerke, ζ Β. Rohr-Reduzierwalzwerke mit Zwei- oder Mehrwalzkalibern bekannt, bei denen sämtliche Walzen von einem einzigen Eintrieb aus über Kegelrader angetrieben werden. Die Walzen sind dabei auf doppelseitig gelagerten Steckwellen gegen einen Wellenabsatz verspannt. Der Ausbau dieser Walzen ist hier sehr umständlich. Er kann praktisch auch nur dadurch bewerkstelligt werden, daß mit den Walzen zusammen auch die sie antreibenden Kegelräder ausgebaut werden.They are stands for universal rolling mills, ζ Β. Tube reducing mills with two or more rolls known, in which all rolls of a single input driven by bevel gears will. The rollers are on double-sided stub shafts against a shaft shoulder tense. The removal of these rollers is very cumbersome here. He can practically only by doing this be accomplished that expanded the bevel gears driving them together with the rollers will.

Der Ausbau der Walzen solcher Gerüste soll eine wesentliche Vereinfachung1 dadurch erfahren, daß die Walzen erfindungsgemäß mit den auf den Steckwellen aufgesetzten Kegelrädern verspannt sind, wobei die an den Walzen anliegenden Naben der Kegelräder in den Lagern der Steckwellen laufen. Weil die Kegelräder mit den Walzen.und Steckwellen eine Einheit bilden, ergibt sich eine außerordentliche Vereinfachung im Aufbau der Kaliber, deren Walzen ausgewechselt werden können, ohne daß die Kegelräder ihren Sitz in dem Lager der Steckwellen verlassen.The expansion of the rolls of such stands is to experience a significant simplification 1 in that the rolls are braced according to the invention with the bevel gears placed on the stub shafts, the hubs of the bevel gears resting on the rolls running in the bearings of the stub shafts. Because the bevel gears form a unit with the rollers and stub shafts, there is an extraordinary simplification in the structure of the calibres, the rollers of which can be exchanged without the bevel gears leaving their seat in the bearing of the stub shafts.

In Fig. 1 ist dieser Walzeneinbau schematisch dargestellt, und zwar für den Walzenantrieb von einer Antriebswelle aus:In Fig. 1, this roller installation is shown schematically, for the roller drive of one Drive shaft from:

Vom nicht dargestellten Getriebe des Walzwerkes her wird die oberhalb oder unterhalb der Kalibermitte gelegene, bei 2 und 3 gelagerte Walzenachse 1 und damit auch die auf dieser Achse 1 befestigte Walze 4 angetrieben. Der Antrieb der Walzen 5 und 6 erfolgt durch die Kegelradpaare 7, 8 bzw. 9, 10 über die bei 11 und 12 gelagerte Walzenachse 13 bzw. die bei 14, 15 gelagerte Walzenachse 16. Die Walzen 4, 5 und 6 sind um ein bestimmtes Maß schräg gestellt.From the gearbox of the rolling mill, not shown, the above or below the caliber center located at 2 and 3 mounted roller axis 1 and thus also attached to this axis 1 Roller 4 driven. The rollers 5 and 6 are driven by the bevel gear pairs 7, 8 and 9, 10 respectively the roller axle 13 mounted at 11 and 12 and the roller axle 16 mounted at 14, 15. The rollers 4, 5 and 6 are inclined by a certain amount.

Fig. 2 zeigt Einzelheiten für die Lagerung und den Antrieb einer Wake, deren Walzenachse als Steckwelle ausgebildet ist:Fig. 2 shows details for the storage and the drive of a wake, the roller axis as a stub shaft is trained:

Das Auswechseln der Walze 5 ohne Ausbau der Lagerungen 11, 12 und des Antriebes 8 geschieht durch Lösen der Schraube 17, die in einiger Entfernung von ihrem Gewindeende 18 einen Bund 19 aufweist. Im antriebsseitigen Ende der Walzenachse 13 ist ein Ringstück 20 mit einer Schulter 21 eingeschraubt. Durch die Schrauben 17, 18 wird die Walzenachse 13 fest mit dem Deckel 22 verbunden und durch eine weitere Maßnahme, nämlich durch Anbringung eines Bundes 18' an der Steckwelle 13, erreicht, daß der Deckel 22 kraftschlüssig mit dem Auf Steckwellen aufgesetzte WalzenThe exchange of the roller 5 takes place without removing the bearings 11, 12 and the drive 8 by loosening the screw 17, which has a collar 19 at some distance from its threaded end 18. A ring piece 20 with a shoulder 21 is screwed into the drive-side end of the roller axle 13. The roller axle 13 is firmly connected to the cover 22 by the screws 17, 18 and by another measure, namely by attaching a collar 18 'to the stub shaft 13, achieves that the cover 22 frictionally with the rollers placed on stub shafts
