Roll stand with rolls adjustable towards one another and mounted in overhung manner, the roll shafts (5, 5) of which are mounted in eccentric bushes (6, 6) rotatably arragned in a housing (1) and are connected for drive through gear wheels (7, 8) at their ends opposite to the rolls with intermediate shafts (9, 9) likewise mounted in the housing (1), in which the eccentric bushes (6, 6) together with the rolls, the roll shafts, the roll shaft bearings and the gear wheels are easily disengageably inserted into the housing from its end, and in which the diameters of the gear wheels (7, 8) and of the eccentric bushes (6, 6) are made smaller than the roll end of the housing (1), characterized in that in the case of a rotary drive for the eccentric bushes (6, 6) through toothed rims (19, 19) arranged on these their diameters too are made smaller than the roll end of the housing (1) and each eccentric bush (6) with pertiment roll, roll shaft mounting, gar wheel (7) and toothed rim (19) can be installed and removed individually, in each case through an end opening of the housing, provided in the stand (1) and dimensioned in accordance with the eccentric bush, the gear wheel and the toothed rim.

Description

Die Erfindung bezieht sich auf ein Walzgerüst mit fliegend gelagerten, gegeneinander anstellbaren Walzen, deren Walzwellen in in einem Gehäuse drehbar angeordneten Exzenterbuchsen gelagert und über Zahnräder an ihren den Walzen gegenüberliegenden Enden mit ebenfalls im Gehäuse gelagerten Zwischenwellen antriebsverbunden sind.The invention relates to a roll stand with overhung, mutually adjustable rollers, the roller shafts of which are mounted in a housing rotatably arranged eccentric bushings and are drive-connected via gear wheels on their ends opposite the rollers with intermediate shafts also mounted in the housing.

Derartige Walzgerüste sollen eine soweit wie möglich ununterbrochene Betriebsweise erlauben. Deshalb muß das Auswechseln von Verschleißteilen in kürzester Zeit durchgeführt werden können. Andererseits sollen die Auswechseleinheiten möglichst klein sein, d. h. sich auf die Verschleißteile beschränken, um die Betriebs- und Wartungskosten sowie den Aufwand für die Ersatzteillagerung niedrig zu halten. Für diesen Zweck sind bereits verschiedene Konstruktionen bekannt geworden ( DPS 742 990, DOS 2304268,US-PS3336781), die eine leicht lösbare Verbindung zwischen einzelnen Teilen eines solchen Walzgerüstes vorsehen und das schnelle Auswechseln dieser Teile ermöglichen. Hierbei werden jedoch immer noch verhältnismäßig umfangreiche Gehäuseteile unter Einschluß von Funktionsteilen, die nur geringem Verschleiß unterliegen, ausgewechselt. Das erfordert dann anschließend aufwendige Montage-, Abdicht- und Ausrichtarbeiten. Es ist Aufgabe der vorliegenden Erfindung, eine Anordnung zu schaffen, die diese Nachteile vermeidet und bei weitgehendem Ausschluß von Gehäuseteilen vom Wechselvorgang diesen praktisch auf die maßgebenden Verschleißteile beschränkt.Roll stands of this type are intended to permit uninterrupted operation as far as possible. Therefore, the replacement of wear parts must be carried out in the shortest possible time. On the other hand, the replacement units should be as small as possible, ie limited to the wear parts, in order to keep the operating and maintenance costs as well as the effort for the spare parts storage low. Various constructions have already become known for this purpose (DPS 742 990, DOS 2304268, US-PS3336781), which provide an easily detachable connection between individual parts of such a rolling stand and enable these parts to be replaced quickly. In this case, however, relatively large housing parts, including functional parts that are subject to only slight wear, are still replaced. This then requires complex assembly, sealing and alignment work. It is an object of the present invention to provide an arrangement which avoids these disadvantages and, in the case of largely excluding housing parts from the changing process, practically limits them to the decisive wear parts.

Danach wird für ein Walzgerüst der eingangs genannten Art vorgeschlagen, daß die Exzenterbuchsen mitsamt den Walzen, den Walzwellen, den Walzwellenlagern und den Zahnrädern einzeln leicht lösbar in das Gehäuse von dessen Stirnseite her durch eine entsprechend bemessene öffnung in dieser eingesetzt sind. Dadurch wird eine Trennung von Gehäuseteilen vermieden. Alle mit dem Gehäuse verbundenen Versorgungsleitungen, Walzarmaturen und Walzführungen können beibehalten werden und bleiben beim Wechselvorgang unverändert. Die Lagerung und Beschaffung der Wechselteile sowie der Wechsel selbst sind erheblich kostengünstiger. Da nur ein einteiliges ortsfestes Gehäuse erforderlich ist, wird auch die Herstellung eines solchen Walzgerüstes billiger.Then it is proposed for a roll stand of the type mentioned that the eccentric bushings together with the rolls, the roll shafts, the roll shaft bearings and the gears are individually easily detachably inserted into the housing from its end face through a correspondingly dimensioned opening in it. This prevents separation of housing parts. All utility lines connected to the housing, W alzarmaturen and roller guides can be maintained and remain with the changing process unchanged. The storage and procurement of the change parts as well as the change itself are considerably cheaper. Since only a one-piece stationary housing is required, the manufacture of such a rolling stand is also cheaper.

Bei einer besonders zweckmäßigen Ausführungsform des vorgeschlagenen Walzgerüstes sind die Durchmesser der Zahnräder und auf den Exzenterbuchsen angeordneter Zahnkränze für die Exzenterverstellung kleiner als die Durchmesser der gehäusestirnseitigen Lager der Exzenter- buchsen ausgeführt. Damit wird erreicht, daß die Öffnung in der Stirnseite des Gehäuses, durch welche die Wechseleinheiten ausgewechselt werden, nicht größer zu sein braucht als der betriebstechnisch vorgegebene Durchmesser der Exzenterbuchsenlager. Trotzdem lassen sich jede der beiden je einer der Walzen zugeordneten Wechseleinheiten für sich oder beide zusammen leicht austauschen.In a particularly expedient embodiment of the proposed rolling stand, the diameters of the gear wheels and toothed rings arranged on the eccentric bushings for the eccentric adjustment are made smaller than the diameters of the bearings of the eccentric bushings on the housing side. This ensures that the opening in the end face of the housing, through which the exchange units are exchanged, need not be larger than the diameter of the eccentric bush bearing specified in terms of operation. Nevertheless, each of the two interchangeable units assigned to one of the rollers can be easily replaced individually or both.

In weiterer Ausgestaltung der Erfindung sind die Exzenterbuchsen auf ihrem Umfang mit einer Nut versehen, in die ein für die Exzenterbuchsen gemeinsamer, im Gehäuse gelagerter Keil mittels einer Spindel einschiebbar ist, der die Exzenterbuchsen axial festlegt und herausgezogen den Ausbau der Exzenterbuchsen erlaubt. Diese Ausführung ergibt eine sehr einfache und betriebssichere Verbindung der Auswechseleinheiten mit dem Gehäuse, gewährleistet aber gleichzeitig ein Lösen dieser Verbindung mit dem geringstmöglichen Aufwand.In a further embodiment of the invention, the eccentric bushings are provided on their circumference with a groove into which a wedge, which is common to the eccentric bushings and is mounted in the housing, can be inserted by means of a spindle, which axially fixes the eccentric bushings and, when pulled out, allows the eccentric bushings to be removed. This design results in a very simple and reliable connection of the exchange units to the housing, but at the same time ensures that this connection is released with the least possible effort.

Ein Gehäuse 1 mit ölbohrungen 2 ist an seinem walzenseitigen Ende mit einer Stirnplatte 3 verschlossen. Zwei mit ihren für die Aufnahme von Walzscheiben bestimmten Enden 4 durch die Stirnplatte 3 hindurchtretende Walzwellen 5 sind in Exzenterbuchsen 6 gelagert, die ihrerseits im Gehäuse 1 drehbar gelagert sind. Die Walzwellen 5 tragen an ihrem anderen Ende Zahnräder 7, deren Außenverzahnungen mit der Innenverzahnung von im Gehäuse 1 konzentrisch zu den Exzenterbuchsen 6 gelagerten Rädern 8 in Eingriff steht, unabhängig von der Stellung der Exzenterbuchsen 6. Die Räder 8 sitzen auf im Gehäuse 1 gelagerten Zwischenwellen 9, die über Stirnräder 10 miteinander antriebsverbunden sind. Eine der beiden Zwischenwellen 9 ist mit dem Walzenantrieb verbunden.A housing 1 with oil bores 2 is closed at its roller-side end with an end plate 3. Two roller shafts 5 with their ends 4 intended for receiving roller disks 4 passing through the end plate 3 are mounted in eccentric bushings 6, which in turn are rotatably mounted in the housing 1. The roller shafts 5 carry at their other end gear wheels 7, the external toothing of which engages with the inner toothing of wheels 8 mounted in the housing 1 concentrically with the eccentric bushes 6, regardless of the position of the eccentric bushings 6. The wheels 8 are seated on intermediate shafts mounted in the housing 1 9 that over Spur gears 10 are drive-connected to one another. One of the two intermediate shafts 9 is connected to the roller drive.

Die Walzenanstellung erfolgt symmetrisch durch gegenläufiges Drehen der Exzenterbuchsen 6 über eine Anstellspindel 11 mit zwei Schneckenverzahnungen 12 und zwei Stellräder 13.The roll adjustment is carried out symmetrically by rotating the eccentric bushes 6 in opposite directions via an adjusting spindle 11 with two worm gears 12 and two adjusting wheels 13.

Jede der beiden Exzenterbuchsen 6 ist mit einer umlaufenden Nut 14 versehen,' in die ein gemeinsamer Keil 15 eingreift, der über Langlöcher 16 und Stifte 17 im Gehäuse 1 verschieblich gelagert ist. Die Exzenterbuchsen 6 sind durch den Keil 15 im Gehäuse 1 in axialer Richtung festgelegt. Der Keil 15 kann mittels einer Spindel 18 aus den Nuten 15 herausgezogen werden. Er gibt dann die Exzenterbuchsen 6 frei, so daß sie einzeln oder gemeinsam stirnseitig aus dem Gehäuse 1 herausgezogen und gewechselt werden können, und zwar jeweils zusammen mit den Walzwellenlagern, den Walzwellen 5 und den Zahnrädern 7.Each of the two eccentric bushes 6 is provided with a circumferential groove 14 'into which a common wedge 15 engages, which is slidably mounted in the housing 1 via elongated holes 16 and pins 17. The eccentric bushes 6 are fixed in the axial direction by the wedge 15 in the housing 1. The wedge 15 can be pulled out of the grooves 15 by means of a spindle 18. He then releases the eccentric bushes 6 so that they can be individually and collectively pulled out and exchanged on the front side from the housing 1, in each case together with the roller shaft bearings, the roller shafts 5 and the gear wheels 7.

Die Öffnung in der Stirnplatte 3 braucht nur so groß wie der vordere Lagerdurchmesser D der Exzenterbuchsen 6 zu sein, da die übrigen Teile der Wechseleinheiten, also die Exzenterbuchsen 6 selbst, der Zahnkranz 19, mit dem die Stellräder 13 kämmen, und auch die Zahnräder 7 so bemessen sind, daß sie keinen größeren Durchmesser bzw. keine größere Ausladung haben.The opening in the end plate 3 need only be as large as the front bearing diameter D of the eccentric bushes 6, since the remaining parts of the exchange units, i.e. the eccentric bushes 6 themselves, the ring gear 19 with which the adjusting wheels 13 mesh, and also the toothed wheels 7 are dimensioned so that they have no larger diameter or larger projection.
