Description

Die Erfindung betrifft eine Vorrichtung zum Antrieb eines Paares von Vertikalwalzen oder deren Tragwellen, die in gegeneinander anstellverschiebbaren Lagereinbaustücken gelagert sind, bei der die Zapfen der Vertikalwalzen oder der Tragwellen mit Antriebsgetriebewellen kuppelbar sind, die jeweils in einem mit dem Einbaustück verbundenen und mit diesem verschiebbaren Getriebegehäuse lagern.The invention relates to a device for driving a pair of vertical rollers or their support shafts, which are mounted in mutually displaceable bearing chocks, in which the pins of the vertical rollers or the support shafts are coupled with drive gear shafts, each in a connected to the chock and this sliding transmission housing to store.

Vorrichtungen dieser Art sind insb. für die Verwendung in Drahtwalzstraßen in unterschiedlichen Ausbildungsformen bekanntgeworden und sollen in diesen bei hohen Drahtgeschwindigkeiten eine präzise Anstellung der Vertikalwalzen und deren leichten Austausch ermöglichen.Devices of this type have esp. For use in wire rolling mills in various forms of training have become known and to allow in these at high wire speeds precise employment of the vertical rollers and their easy replacement.

Nach der US-PS 3,670,587 sind die beiden Vertikalwalzen von oben her in die, in einem Führungsrahmen horizontal verfahr- und gegeneinander anstellbar angeordneten Lagereinbaustücke einsetzbar. Auf ihre nach oben aufstehenden Antriebszapfen sind dabei Kuppelmuffen aufschiebbar, die über an diese angelenkte Gelenkspindeln und eine, diesen gemeinsame Getriebeanordnung, drehantreibbar sind. Bei einer weiteren, aus der EP 139 199 A1 bekannten Vorrichtung sind die Vertikalwalzen jeweils in einem horizontal verschiebbaren Traggehäuse gelagert und mit ihren nach unten gerichteten Antriebszapfen mit einem Getriebe gekuppelt, dessen Gehäuse mit dem Traggehäuse der Vertikalwalzen verbunden und verschiebbar ist. Die beiden Traggehäuse-Gehäusekombinationen sind gegeneinander anstellverschiebbar und ihre Vertikalwalzen werden über eine Verschiebekupplungsanordnung von je einem Antriebsaggregat angetrieben, das seitlich unterhalb der jeweiligen Kombination angeordnet ist.According to US-PS 3,670,587, the two vertical rollers from above into the, in a guide frame horizontally movable and against each other arranged adjustable bearing chocks are used. In this case, coupling sleeves can be slid onto their upwardly projecting drive pins, which are rotatably driven via articulated spindles articulated on them and one, this common transmission arrangement. In a further known from EP 139 199 A1 device, the vertical rollers are each mounted in a horizontally displaceable support housing and coupled with their downwardly directed drive pin with a gearbox, whose housing is connected to the support housing of the vertical rollers and slidable. The two support housing-housing combinations are against each other and anstellverschiebbar their vertical rollers are driven by a sliding coupling arrangement of a respective drive unit, which is arranged laterally below the respective combination.

Eine weitere, aus JP 57190703 bekannte Vorrichtung zeigt ein Paar von Horizontalwalzen, von denen jede auf eine Walzentragwelle aufgesetzt ist, die in einem Lagergehäuse lagert, das seinerseits fest mit einem Getriebegehäuse mit angeflanschtem Antriebsmotor verbunden ist. Beide Gehäuse-Motor-Kombinationen sind miteinander schwenkverbunden. Die Anstellung der Walzen wird durch Schwenken dieser Gehäuse-Motor-Kombination bewirkt. Für die Anwendung in Drahtwalzstraßen kann diese Kombination mit Hilfe entsprechender Tragrahmen in unterschiedliche Winkellagen gebracht werden, wobei die Walzentragwellen eine entsprechende Winkelposition zur Walzlinie einnehmen.Another known from JP 57190703 device shows a pair of horizontal rollers, each of which is mounted on a roller follower shaft which supports in a bearing housing, which in turn is fixedly connected to a gear housing with flanged drive motor. Both housing-motor combinations are pivotally connected to each other. The employment of the rollers is effected by pivoting this housing-motor combination. For use in wire rod mills, this combination can be brought by means of corresponding support frame in different angular positions, wherein the roll center shafts take a corresponding angular position to the rolling line.

Das Dokument DE-A-2 247 622 zeigt eine Vorrichtung zum Antrieb eines Paares von in gegeneinander anstellverschiebbaren Lagereinbaustücken gelagerten Vertikalwalzen oder deren Tragwellen, bei der die Zapfen der Vertikalwalzen oder der Tragwellen mit Antriebsgetriebewellen kuppelbar sind, die in je einem, mit den Lagereinbaustücken verbundenen und mit diesen verschiebbaren Getriebegehäuse lagern, wobei die Antriebsgetriebewellen als vertikal gelagerte, einseitige Kegelradwellen ausgebildet sind, deren Kegelräder mit Kegelrädern von horizontal koaxial in dem jeweiligen Getriebegehäuse gelagerten Kegelradwellen in der Form von einseitigen Kegelradhohlwellen kämmen.The document DE-A-2 247 622 shows an apparatus for driving a pair of vertical rollers or their support shafts supported in mutually displaceable bearing chocks, in which the pins of the vertical rollers or the support shafts can be coupled to drive gear shafts which are each connected to the bearing chocks and store with these sliding gear housing, wherein the drive gear shafts are formed as vertically mounted, one-sided bevel gear, the bevel gears mesh with bevel gears of horizontally coaxially mounted in the respective gear housing bevel gear shafts in the form of single-sided bevel gear hollow shafts.

Alle diese bekannten Ausbildungsformen bauen sehr aufwendig, benötigen zum Teil zwei Antriebsaggregate und erschweren wegen der zu bewegenden großen Massen die für die Endgerüste von Drahtwalzstraßen notwendige präzise und schnelle Anstellung der Vertikalwalzen.All these known forms of training build very expensive, sometimes require two drive units and complicate the necessary because of the large masses to be moved to the end frames of wire rolling mills precise and fast employment of vertical rolls.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäßen Vorrichtungen so zu verbessern, dass neben einem erheblich geringeren Bauaufwand und mit nur einem Antriebsaggregat für die Vorrichtung eine schnelle und präzise Walzenanstellung möglich gemacht wird.The invention has for its object to improve the generic devices so that in addition to a significantly lower construction costs and with only one drive unit for the device a fast and accurate roller adjustment is made possible.

Diese Aufgabe wird dadurch gelöst, dass die Antriebsgetriebewellen als vertikal gelagerte einseitige Kegelradwellen ausgebildet sind, deren Kegelräder mit Kegelrädern von horizontal, koaxial in den jeweiligen Getriebetraggehäuse gelagerten, ebenfalls einseitigen Kegelradwellen in der Form von Kegelradhohlwellen kämmen, die über ein, ein innenseitiges Zahnwellenprofil mit dem außenseitigen Zahnwellenprofil einer, zwischen beiden Hohlwellen angeordneten schwimmenden Zwischenwelle verbunden, mit dem Antriebsaggregat kuppelbar sind.This object is achieved in that the drive gear shafts are designed as vertically mounted one-sided bevel gear shafts whose bevel gears mesh with bevel gears of horizontal, coaxially mounted in the respective Getriebetraggehäuse, also one-sided bevel gear shafts in the form of bevel hollow shafts, the one, an inside splined shaft profile connected to the outside spline shaft profile of a, arranged between two hollow shafts floating intermediate shaft, are coupled to the drive unit.

Dabei können die vertikal gelagerten Kegelradwellen an ihren den Kegelrädern abgewandten Enden als Treffer für die Zapfen der Vertikalwalzen ausgebildet sein.The vertically mounted bevel gear shafts may be formed at their ends remote from the bevel gears as a hit for the pins of the vertical rolls.

Die Erfindung wird anhand des, in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:

Fig. 1
die Ansicht der Vorrichtung, in Walzrichtung gesehen, teilweise geschnitten und
Fig. 2
eine Teildarstellung der Ansicht nach Fig. 1, ebenfalls teilweise geschnitten, im vergrößerten Maßstab.
The invention will be explained in more detail with reference to the embodiment shown in the drawing. In the drawing show:
Fig. 1
the view of the device, as seen in the rolling direction, partially cut and
Fig. 2
a partial view of the view of FIG. 1, also partially cut, on an enlarged scale.

Die beiden Vertikalwalzringe VWR1 und VWR2 nach Fig. 1 sind auf Walzentragwellen WTW1 und WTW2 aufgeschoben, die jeweils in einem der beiden, auf nicht dargestellte Weise horizontal gegeneinander und voneinander weg verschiebbaren Lagereinbaustücke LES1 und LES2 lagern. Unter diesen sind zwei Getriebegehäuse GG1 und GG2 angeordnet und mit dem jeweiligen Lagereinbaustück LES1 bzw. LES2 formschlüssig verbunden. In diesem lagert vertikal je eine Kegelradwelle KW1 bzw. KW2 mit nach unten gerichteten Kegelrädern KR1 bzw. KR2. Diese kämmen (vergl. Fig. 2) mit Kegelrädern KR3 bzw. KR4 von horizontal und koaxial zueinander in den Getriebegehäusen GG1 bzw. GG2 gelagerten Kegelradhohlwellen KHW3 bzw. KHW4. Die eine der Kegelradhohlwellen KHW3 ist mit einer Antriebsspindel ASP axial verschiebbar gekuppelt. Beide Kegelradhohlwellen KHW3 und KHW4 weisen innenseitig jeweils eine Zahnwellenprofilierung ZPI3 bzw. ZPI4 auf. In diesen Zahnwellenprofilierungen ist eine Zwischenwelle axial schwimmend verschiebbar, deren Endabschnitte ZWA3 und ZWA4 mit außenseitigen Zahnwellenprofilierungen ZPA3 bzw. ZPA4 in die innenseitigen Zahnwellenprofilierungen ZPI3 bzw. ZPI4 der Kegelradhohlwellen KHW 3 bzw. KHW4 eingreifen und in diesen axial verschiebbar sind.The two vertical rolling rings VWR1 and VWR2 according to FIG. 1 are pushed onto roller support shafts WTW1 and WTW2, which respectively support the bearing chocks LES1 and LES2, which are horizontally displaceable relative to each other and away from each other, in a manner not shown. Among these, two gearboxes GG1 and GG2 are arranged and positively connected to the respective bearing chock LES1 or LES2. In this vertically stored each bevel gear shaft KW1 or KW2 with downwardly directed bevel gears KR1 and KR2. These mesh (see Fig. 2) with bevel gears KR3 and KR4 of horizontal and coaxial with each other in the gear housings GG1 and GG2 stored Kegelradhohlwellen KHW3 and KHW4. One of the bevel hollow shafts KHW3 is axially slidably coupled to a drive spindle ASP. Both bevel hollow shafts KHW3 and KHW4 each have on the inside a spline profiling ZPI3 or ZPI4. In these toothed shaft profiling an intermediate shaft is axially floating displaced, the end portions ZWA3 and ZWA4 with outside Radial shaft profiling ZPA3 or ZPA4 engage in the inside of the toothed shaft profiling ZPI3 or ZPI4 the Kegelradhohlwellen KHW 3 or KHW4 and are axially displaceable in this.

Wie ersichtlich, können die in den beiden Getriebegehäuse GG1, GG2 lagernden Kegelradwellen KW1 bzw. KW2 den horizontalen, bei Anstellung der Vertikalwalzringe VWR1, VWR2 bewirkten Verschiebebewegungen der Lagereinbaustücke LES1 bzw. LES2 und der Getriebegehäuse GG1 GG2 folgen, weil die Kegelradhohlwellen KHW3 und KHW4 über ihre Zahnwellenprofilkupplung mit der Zwischenwelle ZW ständig antriebsverbunden bleiben.As can be seen, the bevel gear shafts KW1 and KW2 stored in the two gearbox housings GG1, GG2 can follow the horizontal displacement motions of the bearing chocks LES1 and LES2 and the gearbox housings GG1 GG2 caused by the vertical rolling rings VWR1, VWR2, because the bevel helical shafts KHW3 and KHW4 over their toothed shaft profile coupling with the intermediate shaft ZW remain permanently connected drive.

Wie weiter aus der Zeichnung ersichtlich, sind die vertikalen Kegelradwellen KW1 und KW2 an ihren, den Kegelrädern KR1 bzw. KR2 abgewandten und den Walzentragwellen WTW1 bzw. WTW2 zugewandten Enden als Treffer TR1 bzw. TR2 zur Aufnahme der Zapfen ZA1 bzw. ZA2 der Walzentragwellen WTW1 bzw. WTW2 ausgebildet.As further apparent from the drawing, the vertical bevel gear shafts KW1 and KW2 are facing away from the bevel gears KR1 and KR2 and the Walzingagwellen WTW1 and WTW2 facing ends as a hit TR1 or TR2 for receiving the pin ZA1 and ZA2 of the roll support shafts WTW1 or WTW2 formed.
