Description

Die vorliegende Erfindung betrifft eine Verdichterwalze, insbesondere für einen Bodenverdichter mit wenigstens einer in Richtung einer Walzendrehachse geteilten Walze, umfassend einen eine Walzendrehachse umgebenden und in Richtung der Walzendrehachse langgestreckten Walzenmantel und in dem vom dem Walzenmantel umgebenen Walzeninnenraum wenigstens eine mit dem Walzenmantel an seiner Innenumfangsfläche verbundene Walzenscheibe.The present invention relates to a compactor roller, in particular for a soil compactor with at least one roller divided in the direction of a roller rotation axis, comprising a roller shell surrounding a roller rotation axis and elongated roll axis in the direction of the roller rotation axis and in the roller interior surrounded by the roll shell at least one connected to the roll shell on its inner circumferential surface rolling wheel.

Bei Bodenverdichtern mit geteilten Walzen, also Walzen, welche in Richtung einer Walzendrehachse aufeinanderfolgend wenigstens zwei um eine gemeinsame Walzendrehachse drehbare Verdichterwalzen umfassen, besteht insbesondere dann, wenn derartigen Verdichterwalzen Systeme zugeordnet sind, mit welchen der Drehbewegung dieser Verdichterwalzen um ihre Walzendrehachse eine Oszillationsbewegung, also eine periodische Hin- und Her-Bewegung bzw. - Beschleunigung in Umfangsrichtung überlagert werden kann, die Gefahr, dass das Betriebsverhalten beeinträchtigende Schwingungen der beiden Verdichterwalzen bezüglich einander, insbesondere Schwingungen um eine Längsachse bzw. eine Höhenachse eines mit derartigen Verdichterwalzen aufgebauten Bodenverdichters, erzeugt werden. Derartige Schwingungen können zu einem gegenseitigen Anstoßen der Verdichterwalzen aneinander mit entsprechender Geräuschentwicklung und auch zu Beschädigungen der Verdichterwalzen bzw. von Aufhängungsbauteilen für die Verdichterwalzen führen.In soil compactors with split rolls, ie rollers which comprise at least two rotatable about a common roll rotation axis compressor rolls in the direction of a roll rotation axis, there is in particular when such compressor rolls systems are assigned, with which the rotational movement of these compressor rolls about its roll axis of rotation an oscillatory motion, ie a Periodic reciprocating motion or - acceleration can be superimposed in the circumferential direction, the risk that the operating behavior impairing vibrations of the two compressor rolls with respect to each other, in particular vibrations about a longitudinal axis or a vertical axis of a constructed with such compactors soil compactor, are generated. Such vibrations can lead to a mutual abutment of the compressor rollers together with corresponding noise and also damage to the compressor rollers or suspension components for the compressor rollers.

Ein Bodenverdichter mit zwei derartigen in Richtung der Walzendrehachse aufeinanderfolgend angeordneten Verdichterwalzen ist aus der EP 0 945 187 A2 bekannt. Die beiden Verdichterwalzen weisen jeweils einen rohrartigen Walzenmantel auf, an dessen Innenumfangsfläche zwei in axialem Abstand zueinander angeordnete, im Wesentlichen gleich gestaltete bzw. gleich dimensionierte Walzenscheiben angebunden sind. In ihrem radial inneren Bereich sind die beiden Walzenscheiben durch ein die Walzendrehachse umgebendes bzw. dazu konzentrisch angeordnetes Nabenrohr miteinander verbunden. Alle im Inneren der beiden Verdichterwalzen vorzusehenden Baugruppen müssen in dem von den beiden Nabenrohren umgebenen Innenraum untergebracht werden.A soil compactor with two such in the direction of the roll rotation axis successively arranged compressor rolls is from the EP 0 945 187 A2 known. The two compressor rolls each have a tubular roll shell, on the inner peripheral surface of which two axial spaced-apart, essentially identically designed or identically dimensioned roll disks are connected. In their radially inner region, the two roller discs are surrounded by a roller rotation axis surrounding or Concentrically arranged hub tube connected to each other. All assemblies to be provided in the interior of the two compressor rolls must be accommodated in the interior surrounded by the two hub pipes.

Es ist die Aufgabe der vorliegenden Erfindung, eine Verdichterwalze, insbesondere für einen Bodenverdichter mit wenigstens einer in Richtung einer Walzendrehachse geteilten Walze, vorzusehen, bei welcher bei einfacher konstruktiver Ausgestaltung das Auftreten eines ungünstigen Schwingungsverhaltens vermieden wird.It is the object of the present invention to provide a compactor roller, in particular for a soil compactor with at least one roller divided in the direction of a roller rotational axis, in which the occurrence of an unfavorable vibration behavior is avoided with a simple structural design.

Erfindungsgemäß wird diese Aufgabe gelöst durch eine Verdichterwalze, insbesondere für einen Bodenverdichter mit wenigstens einer in Richtung einer Walzendrehachse geteilten Walze, umfassend einen eine Walzendrehachse umgebenden und in Richtung der Walzendrehachse langgestreckten Walzenmantel und in dem vom dem Walzenmantel umgebenen Walzeninnenraum wenigstens eine mit dem Walzenmantel an seiner Innenumfangsfläche verbundene Walzenscheibe.According to the invention, this object is achieved by a compactor roller, in particular for a soil compactor with at least one roller divided in the direction of a roller rotation axis, comprising a roller shell surrounding a roller rotation axis and elongated in the direction of the roller rotation axis and in the roll interior surrounded by the roll shell at least one with the roll shell at its Inner peripheral surface connected roll plate.

Diese Verdichterwalze zeichnet sich dadurch aus,

  • dass die Walzenscheibe eine Dicke von wenigstens 40 mm aufweist, oder/und
  • dass in Zuordnung zu der Walzenscheibe eine Versteifungsanordnung mit einem im Walzeninnenraum in axialem Abstand zu der Walzenscheibe angeordneten, mit dem Walzenmantel an seiner Innenumfangsfläche verbundenen Versteifungsring und einer mit der Walzenscheibe und dem Versteifungsring verbundenen Versteifungsbaugruppe vorgesehen ist.
This compactor roll is characterized by
  • that the roller disc has a thickness of at least 40 mm, and / or
  • that in association with the roll disk, a stiffening arrangement is provided with a stiffening ring arranged in the roll interior at an axial distance from the roll disk, connected to the roll shell on its inner peripheral surface, and a stiffening assembly connected to the roll disk and the stiffening ring.

Durch das Bereitstellen einer vergleichsweise dicken Walzenscheibe wird die Verdichterwalze in sich versteift, so dass das Entstehen von zu Schwingungen führenden Verformungen einer derartigen Verdichterwalze weitestgehend vermieden wird. Alternativ oder zusätzlich kann durch das Bereitstellen einer Versteifungsanordnung mit einem Versteifungsring und einer diesen mit der Walzenscheibe verbindenden Versteifungsbaugruppe bei einer für andere Systembereiche im Inneren der Verdichterwalze ausreichend Bauraum belassenden Ausgestaltung das Auftreten von zu Schwingungen führenden Verformungen der Verdichterwalze unterbunden werden.By providing a comparatively thick roller disk, the compressor roller is stiffened in itself, so that the formation of vibrations leading to vibrations of such a compressor roller is largely avoided. Alternatively or additionally, by providing a stiffening arrangement with a stiffening ring and a stiffening assembly connecting the latter with the roller disc, a sufficient space can be left in the interior of the compressor roller for other system areas Design the occurrence of vibrations leading to deformations of the compressor roller can be prevented.

Eine unter Berücksichtigung der Notwendigkeit, die Verdichterwalze an eine Aufhängung anbinden zu müssen, und der Notwendigkeit, im Inneren einer derartigen Verdichterwalze Bauraum für weitere Systembereiche, beispielsweise einer zur Erzeugung einer Oszillationsbewegung vorgesehenen Unwuchtmassenanordnung, zu belassen, ausreichende Steifigkeit der erfindungsgemäß aufgebauten Verdichterwalze kann dadurch erreicht werden, dass die Walzenscheibe einen ringartigen Scheibenkörper aufweist, wobei der Scheibenkörper sich in radialer Richtung über wenigstens 50%, vorzugsweise wenigstens 60%, der Radialerstreckung der Walzenscheibe erstreckt, oder/und dass der Versteifungsring einen Ringkörper aufweist, wobei der Ringkörper eine kürzere Radialerstreckung aufweist, als ein Scheibenkörper der Walzenscheibe, oder/und sich über weniger als 50%, vorzugsweise weniger als 30%, der Radialerstreckung des Versteifungsrings erstreckt.A sufficient rigidity of the compressor roller constructed according to the invention can be achieved by taking into account the necessity of having to connect the compacting roller to a suspension and the necessity of leaving space inside such a compacting roller for further system areas, for example an imbalance mass arrangement intended to produce an oscillation movement in that the roller disc has an annular disc body, wherein the disc body extends in the radial direction over at least 50%, preferably at least 60%, of the radial extent of the roller disc, and / or that the stiffening ring has an annular body, wherein the annular body has a shorter radial extent , as a disc body of the roller disc, and / or extending over less than 50%, preferably less than 30%, of the radial extent of the stiffening ring.

Zur Erhöhung der Steifigkeit kann der Ringkörper in wenigstens zwei bezüglich der Walzendrehachse einander gegenüberliegenden ersten Umfangsbereichen eine größere Radialerstreckung aufweisen, als in zwischen zwei ersten Umfangsbereichen liegenden zweiten Umfangsbereichen.In order to increase the rigidity, the annular body can have a greater radial extent in at least two first circumferential regions lying opposite one another relative to the roller rotational axis than in second circumferential regions lying between two first circumferential regions.

Die Versteifungsbaugruppe kann wenigstens eine bezüglich der Walzendrehachse exzentrisch angeordnete erste Versteifungsplatte umfassen, wobei die wenigstens eine erste Versteifungsplatte in einem ersten axialen Endbereich mit der Walzenscheibe verbunden ist und in einem zweiten axialen Endbereich mit dem Versteifungsring verbunden ist. Eine derartige erste Versteifungsplatte kann in einfacher Art und Weise in den Innenraum der Verdichterwalze integriert werden und kann aufgrund ihrer inhärenten Steifigkeit Verformungen der Verdichterwalze entgegenwirken.The stiffening assembly may comprise at least one first stiffening plate eccentrically arranged with respect to the roller rotational axis, the at least one first stiffening plate being connected to the roller disc in a first axial end region and being connected to the stiffening ring in a second axial end region. Such a first stiffening plate can be easily integrated into the interior of the compressor roller and can counteract due to their inherent stiffness deformations of the compressor roller.

Zur Verbindung einer derartigen ersten Versteifungsplatte mit dem Versteifungsring kann die wenigstens eine erste Versteifungsplatte in ihrem zweiten axialen Endbereich in ihren beiden radialen Endbereichen jeweils einen mit dem Versteifungsring verbundenen Verbindungssteg umfassen.To connect such a first stiffening plate with the stiffening ring, the at least one first stiffening plate in its second axial End region in their two radial end regions each comprise a connecting web connected to the stiffening ring.

Die Steifigkeit einer erfindungsgemäß aufgebauten Verdichterwalze kann dadurch weiter erhöht werden, dass die wenigstens eine erste Versteifungsplatte in ihren radialen Endbereichen mit dem Walzenmantel an seiner Innenumfangsfläche verbunden ist.The stiffness of a compressor roller designed according to the invention can be further increased by connecting the at least one first stiffening plate in its radial end regions to the roll shell on its inner circumferential surface.

Das Auftreten von Unwuchten im Rotationsbetrieb einer Verdichterwalze kann dadurch verhindert werden, dass die Versteifungsbaugruppe zwei erste Versteifungsplatten umfasst, wobei die ersten Versteifungsplatten beidseits der Walzendrehachse und zueinander im Wesentlichen parallel vorgesehen sind. Es wird somit bezüglich der Walzendrehachse eine im Wesentlichen symmetrische Anordnung der Komponenten der Versteifungsbaugruppe ermöglicht.The occurrence of imbalances in the rotary operation of a compressor roller can be prevented by the stiffening assembly comprising two first stiffening plates, wherein the first stiffening plates are provided on both sides of the roller rotation axis and substantially parallel to each other. It is thus possible with respect to the roller rotation axis, a substantially symmetrical arrangement of the components of the stiffening assembly.

Die Steifigkeit einer erfindungsgemäß aufgebauten Verdichterwalze kann weiter dadurch erhöht werden, dass die Versteifungsbaugruppe eine mit der Walzenscheibe verbundene zweite Versteifungsplatte umfasst, wobei die zweite Versteifungsplatte nicht mit dem Walzenmantel oder/und dem Versteifungsring verbunden ist, oder/und wobei die zweite Versteifungsplatte die Walzendrehachse schneidet. Dabei kann die zweite Versteifungsplatte zwischen den ersten Versteifungsplatten angeordnet sein.The stiffness of a compactor roller constructed in accordance with the invention can be further enhanced by the stiffener assembly comprising a second stiffener plate connected to the roller disc, the second stiffener plate not being connected to the roll shell and / or the stiffener ring, and / or the second stiffener plate intersecting the roller rotation axis , In this case, the second stiffening plate can be arranged between the first stiffening plates.

Bei einer weiteren Ausgestaltungsvariante kann die Versteifungsbaugruppe wenigstens eine mit der Walzenscheibe und dem Versteifungsring verbundene Versteifungsstrebe umfassen.In a further embodiment variant, the stiffening assembly may comprise at least one stiffening strut connected to the roller disc and the stiffening ring.

Auch bei diesem Aufbau kann das Auftreten von Unwuchten im Rotationsbetrieb einer Verdichterwalze bei weiter erhöhte Steifigkeit derselben dadurch vermieden werden, dass die Versteifungsbaugruppe eine Mehrzahl von um die Walzendrehachse mit Abstand zueinander angeordneten Versteifungsstreben umfasst.Also in this structure, the occurrence of imbalances in the rotary operation of a compressor roller with further increased rigidity thereof can be avoided by the stiffening assembly comprising a plurality of stiffening struts spaced around the roller rotation axis.

Wenigstens eine, vorzugsweise jede Versteifungsstrebe kann mit zur Walzendrehachse nicht paralleler, vorzugsweise die Walzendrehachse schneidender Strebenlängsachse angeordnet sein. Bei derartiger Positionierung der Versteifungsstrebe/n wird insbesondere in denjenigen Bereichen, in welchen ein größerer Abstand zur Walzendrehachse besteht, ausreichend Bauraum für andere Systembereiche im Inneren der Verdichterwalze bereitgestellt.At least one, preferably each stiffening strut can be arranged with the longitudinal axis of the roller not parallel, preferably the roller rotation axis intersecting strut longitudinal axis. With such positioning of the stiffening strut / s, sufficient space for other system areas in the interior of the compressor roller is provided, in particular in those areas in which there is a larger distance to the roller rotational axis.

Die vorliegende Erfindung betrifft ferner einen Bodenverdichter, umfassend wenigstens eine, vorzugsweise zwei in Richtung der Walzendrehachse aufeinanderfolgende Verdichterwalzen mit erfindungsgemäßem Aufbau.The present invention further relates to a soil compactor, comprising at least one, preferably two in the direction of the roll axis of rotation successive compressor rollers with inventive construction.

Die Fig. 1 bis 3 zeigen eine erste Ausgestaltungsart einer Vedichterwalze, die bei einem selbstfahrenden Bodenverdichter mit wenigstens einer in Richtung einer Walzendrehachse geteilten Walze eingesetzt werden kann.The Fig. 1 to 3 show a first Ausgestaltungsart a Vedichterwalze, which can be used in a self-propelled soil compactor with at least one divided in the direction of a roll rotation axis roller.

Die in den Fig. 1 bis 3 dargestellte Verdichterwalze 10 umfasst einen ring- bzw. rohrartigen Walzenmantel 12, der eine Walzendrehachse A konzentrisch umgibt und in Richtung der Walzendrehachse A langgestreckt ist. In einem von dem Walzenmantel 12 umgebenden Walzeninnenraum 14 ist nahe einem axialen Endbereich 16 des Walzenmantels 12 eine Walzenscheibe 18, allgemein auch als Ronde bezeichnet, angeordnet. Die in den Fig. 2 und 3 deutlich erkennbare Walzenscheibe 18 weist einen ringartigen Scheibenkörper 20 mit einer zentralen Öffnung 22 auf. Der Walzenkörper 20 weist ausgehend von seinem Außenumfangsbereich 24, mit welchem dieser beispielsweise durch Verschweißung an eine Innenumfangsfläche 26 des Walzenmantels 12 angebunden ist, bis zur zentralen Öffnung 22 eine Radialerstreckung auf, welche wenigstens 50%, vorzugsweise wenigstens 60% des Radius der im Allgemeinen mit kreisartiger Außenumfangskontur bereitgestellten Walzenscheibe 18 beträgt.The in the Fig. 1 to 3 shown compressor roller 10 includes a ring-like or tubular roll shell 12 which surrounds a roller rotation axis A concentric and is elongated in the direction of the roller rotation axis A. In a roll interior 14 surrounding the roll shell 12, near a axial end region 16 of the roll shell 12, a roll disk 18, also generally referred to as a blank, is arranged. The in the Fig. 2 and 3 clearly visible roller disc 18 has an annular disc body 20 with a central opening 22. The roller body 20 has, starting from its outer peripheral region 24, with which it is connected, for example by welding to an inner peripheral surface 26 of the roll shell 12, to the central opening 22 to a radial extent which at least 50%, preferably at least 60% of the radius of generally with circular outer periphery contour provided roller plate 18 is.

Um die Verdichterwalze 10 mit ausreichend hoher Steifigkeit bereitzustellen, weist die Walzenscheibe 18, welche, ebenso wie im Wesentlichen alle anderen Bauteile bzw. Baugruppen der in den Figuren dargestellten Verdichterwalze 10, vorzugsweise aus Stahlmaterial aufgebaut ist, eine Dicke von wenigstens 40 mm auf. Eine derart große Dicke der Walzenscheibe 18, über welche die Verdichterwalze 10 an einen Walzenantrieb angebunden sein kann, führt selbst dann, wenn nur in einem einem axialen Endbereich 16 des Walzenmantels 12 nahe liegenden Bereich der Verdichterwalze 10 eine derartige Walzenscheibe 18 vorgesehen ist, zu einer derart hohen Steifigkeit, dass im Drehbetrieb unter den insbesondere bei Auftreten von durch einen entsprechenden Mechanismus erzeugten Oszillationsbewegungen hervorgerufenen Kräften eine Verformung der Verdichterwalze 10 im Wesentlichen ausgeschlossen werden kann.In order to provide the compacting roll 10 with sufficiently high rigidity, the roll plate 18, which, as well as substantially all other components or assemblies of the compacting roll 10 shown in the figures, is preferably constructed of steel material has a thickness of at least 40 mm. Such a large thickness of the roller disc 18, via which the compressor roller 10 can be connected to a roller drive, even if only in one axial end region 16 of the roller shell 12 near area of the compressor roller 10 such a roller plate 18 is provided to a such a high rigidity that, in the rotary operation under the forces caused in particular by the occurrence of oscillatory movements produced by a corresponding mechanism, a deformation of the compressor roller 10 can be substantially ruled out.

Um die Verdichterwalze 10 mit ausreichend hoher Steifigkeit bereitzustellen, kann alternativ oder zusätzlich im Walzeninnenraum 14 eine allgemein mit 28 bezeichnete Versteifungsanordnung vorgesehen sein. In dem in den Fig. 1 bis 3 dargestellten Ausgestaltungsbeispiel umfasst die Versteifungsanordnung 28 einen Versteifungsring 30, der näher an einem axialen Endbereich 32 des Walzenmantels 12 angeordnet, ist als an dem axialen Endbereich 16, in dessen Nähe die Walzenscheibe 18 positioniert ist. Dies wiederum bedeutet, dass die Walzenscheibe 18 einen größeren Axialabstand zum axialen Endbereich 32 des Walzenmantels 12 aufweist, als zum axialen Endbereich 16 desselben.In order to provide the compressor roller 10 with sufficiently high rigidity, alternatively or additionally, a stiffening arrangement generally designated 28 may be provided in the roller interior 14. In the in the Fig. 1 to 3 illustrated embodiment, the stiffening assembly 28 includes a stiffening ring 30, which is located closer to an axial end portion 32 of the roll shell 12, as at the axial end portion 16, in the vicinity of the roller plate 18 is positioned. This in turn means that the roller disc 18 has a greater axial distance to the axial end portion 32 of the roll shell 12, as compared to the axial end portion 16 thereof.

Der Versteifungsring 30 umfasst einen Ringkörper 34, der an zwei bezüglich der Walzendrehachse A einander gegenüberliegenden ersten Umfangsbereichen 36, ausgehend von seinem Außenumfangsbereich 38, eine größere Radialerstreckung nach radial innen aufweist, als in zwischen den ersten Umfangsbereichen 36 liegenden zweiten Umfangsbereichen 40. Auch in diesen ersten Umfangsbereichen 36 mit größerer Radialerstreckung ist der Ringkörper 34 mit einer Radialerstreckung ausgebildet, die kleiner ist, als die Radialerstreckung des Scheibenkörpers 20 der Walzenscheibe 18, insbesondere kleiner ist als 50% des Radius des Versteifungsrings 30, vorzugsweise kleiner ist als 30% dieses Radius. Man erkennt, dass die in der Walzenscheibe 18 ausgebildete zentrale Öffnung 22, ausgehend von der Walzendrehachs A, eine deutlich kleinere Radialerstreckung aufweist, als eine im Versteifungsring 30 ausgebildete zentrale Öffnung 42.The stiffening ring 30 comprises an annular body 34 which, at two with respect to the roller rotational axis A opposite first peripheral portions 36, starting from its outer peripheral portion 38, a greater radial extent radially inward, as lying in between the first peripheral portions 36 second peripheral regions 40. In these first circumferential portions 36 with greater radial extent of the annular body 34 is formed with a radial extent which is smaller than the radial extent of the disk body 20 of the roller plate 18, in particular less than 50% of the radius of the stiffening ring 30, preferably less than 30% of this radius. It can be seen that the central opening 22 formed in the roller disc 18, starting from the roller turning axis A, has a significantly smaller radial extent than a central opening 42 formed in the stiffening ring 30.

Der Versteifungsring 30 ist mit seinem Außenumfangsbereich 40 beispielsweise durch Verschweißung an die Innenumfangsfläche 26 des Walzenmantels 12 angebunden.The stiffening ring 30 is connected with its outer peripheral region 40, for example by welding to the inner peripheral surface 26 of the roll shell 12.

Zwischen der Walzenscheibe 18 und dem Versteifungsring 30 ist eine allgemein mit 44 bezeichnete Versteifungsbaugruppe vorgesehen. Diese umfasst zwei beidseits der Walzendrehachse A angeordnete, in Richtung dieser Walzendrehachse A sich parallel zueinander erstreckende und zur Walzendrehachse A im Wesentlichen den gleichen Abstand aufweisende erste Versteifungsplatten 46. Jede der ersten Versteifungsplatten 46 ist in einem ersten axialen Endbereich 48 derselben an die Walzenscheibe 18 beispielsweise durch Verschweißung angebunden, wobei die beiden radialen Endbereiche 50, 52 der ersten Versteifungsplatten 46 im Bereich des Außenumfangsbereichs 24 der Walzenscheibe 18 liegen. Somit erstrecken sich diese radialen Endbereiche 50, 52 der ersten Versteifungsplatten 46 in Richtung der Walzendrehachse A im Wesentlichen parallel zu dieser entlang der Innenumfangsfläche 26 des Walzenmantels 12 und sind an diesen durch Verschweißung angebunden.Between the roller plate 18 and the stiffening ring 30 is a generally designated 44 stiffening assembly is provided. This comprises two on both sides of the roller rotation axis A, in the direction of this roller rotation axis A extending parallel to each other and to the roller rotation axis A substantially the same distance having first stiffening plates 46. Each of the first stiffening plates 46 is in a first axial end portion 48 thereof to the roller plate 18, for example connected by welding, wherein the two radial end portions 50, 52 of the first stiffening plates 46 in the region of the outer peripheral portion 24 of the roller plate 18 are. Thus, these radial end portions 50, 52 of the first stiffener plates 46 extend in the direction of the roll rotation axis A substantially parallel thereto along the inner circumferential surface 26 of the roll mantle 12 and are bonded thereto by welding.

In ihren an den Versteifungsring 30 anschließenden zweiten axialen Endbereichen 54 weisen die ersten Versteifungsplatten 46 in ihren beiden radialen Endbereichen 50, 52 jeweils einen Verbindungssteg 56, 58 auf. Jeder der Verbindungsstege 56, 58 weist näherungsweise eine Breite auf, die der radialen Erstreckung des Versteifungsrings 30 in seinen zweiten Umfangsbereichen 40 entspricht. Mit den beiden Verbindungsstegen 56, 58 sind die ersten Versteifungsplatten 46 an den Versteifungsring 30 durch Verschweißung angebunden. Es sei hier darauf hingewiesen, dass vorzugsweise dort, wo die ersten Versteifungsplatten 46 mit ihren axialen Endbereichen 48, 54 an der Walzenscheibe 18 bzw. dem Versteifungsring 30 anliegen, jeweils entlang des gesamten Anlagebereichs eine Schweißverbindung hergestellt ist, beispielsweise bereitgestellt durch im Wesentlichen unterbrechungsfrei durchlaufende Schweißnähte oder mit Abstand zueinander angeordnete Schweißnahtabschnitte oder Schweißpunkte. Auch dort, wo die ersten Versteifungsplatten 46 mit ihren radialen Endbereichen 50, 52 an der Innenumfangsfläche 26 des Walzenmantels 12 anliegen bzw. damit verbunden sind, ist vorzugsweise über die gesamte axiale Erstreckung der ersten Versteifungsplatten 46 eine Schweißverbindung hergestellt.In their second axial end regions 54 adjoining the stiffening ring 30, the first stiffening plates 46 each have a connecting web 56, 58 in their two radial end regions 50, 52. Each of the connecting webs 56, 58 has approximately a width which corresponds to the radial extent of the reinforcing ring 30 in its second peripheral regions 40. With the two connecting webs 56, 58, the first stiffening plates 46 are connected to the stiffening ring 30 by welding. It should be noted here that preferably, where the first stiffening plates 46 abut with their axial end portions 48, 54 on the roll plate 18 and the stiffening ring 30, respectively, a weld joint is made along the entire abutment region, for example, provided by substantially uninterrupted continuous Welds or spaced apart weld sections or welds. Also, where the first stiffening plates 46 abut with their radial end portions 50, 52 on the inner peripheral surface 26 of the roll shell 12 or are connected thereto, preferably over the entire axial extent of the first stiffening plates 46, a welded connection is made.

Zwischen den beiden ersten Versteifungsplatten 46 ist eine zweite Versteifungsplatte 60 vorgesehen. Diese weist sowohl in radialer Richtung, als auch in axialer Richtung eine deutlich kürzere Erstreckung auf, als die ersten Versteifungsplatten 46, so dass sie im Wesentlichen nur an der Walzenscheibe 18 anliegend positioniert ist und in diesem Bereich mit der Walzenscheibe 18 durch Verschweißung verbunden ist. Die zweite Versteifungsplatte 60, welche auch als Balken ausgebildet sein könnte, berührt somit weder den Versteifungsring 30, noch den Walzenmantel 12 und ist vorzugsweise derart angeordnet, dass sie zur Herbeiführung einer optimalen Versteifung der Walzenscheibe 18 die Drehachse A schneidet.Between the two first stiffening plates 46, a second stiffening plate 60 is provided. This has both in the radial direction, as well as in the axial direction a significantly shorter extent than the first stiffening plates 46, so that it is positioned substantially only adjacent to the roll plate 18 and is connected in this area with the roll plate 18 by welding. The second stiffening plate 60, which could also be designed as a beam, thus touches neither the stiffening ring 30, nor the roll shell 12 and is preferably arranged such that it intersects the rotation axis A to bring about optimal stiffening of the roller disc 18.

Durch das Bereitstellen der beiden ersten Versteifungsplatten 46 sowie der zweiten Versteifungsplatten 60 und des Versteifungsrings 30 im Walzeninnenraum 26 wird bei einer substantiellen Versteifung der Verdichterwalze 10 ausreichend Bauraum belassen für Systembereiche, die im Walzeninnenraum 26 anzuordnen sind. Derartige Systembereiche können sowohl Komponenten umfassen, die dem Drehantrieb der Verdichterwalze 10 dienen, als auch Komponenten, die zur Erzeugung einer Oszillationsbewegung oder einer Vibrationsbewegung der Verdichterwalze 10 eingesetzt werden können.By providing the two first stiffening plates 46 and the second stiffening plates 60 and the stiffening ring 30 in the roller interior 26, a substantial stiffening of the compressor roller 10 leaves sufficient space for system areas which are to be arranged in the roller interior 26. Such system areas may include both components that serve to rotationally drive the compressor roller 10 and components that may be used to produce an oscillatory motion or a vibratory motion of the compressor roller 10.

Eine alternative Ausgestaltungsart der Verdichterwalze 10 ist in den Fig. 4 bis 6 gezeigt. Komponenten, welche vorangehend beschriebenen Komponenten hinsichtlich Aufbau bzw. Funktion entsprechen, sind mit dem gleichen Bezugszeichen bezeichnet.An alternative embodiment of the compressor roller 10 is in the 4 to 6 shown. Components which correspond to components described above in terms of construction or function are denoted by the same reference numeral.

Auch bei der in den Fig. 4 bis 6 dargestellten Verdichterwalze 10 kann die Walzenscheibe 18 derselben mit einer Dicke von mehr als 40 mm aufgebaut sein, um bereits dadurch eine substantielle Versteifung der Verdichterwalze 10 zu erzeugen. Die für eine weitere Versteifung vorgesehene Versteifungsanordnung 28 umfasst wieder den näher am axialen Endbereich 32 des Walzenmantels 12 angeordneten Versteifungsring 30. Die den Versteifungsring 30 mit der Walzenscheibe 18 verbindende Versteifungsbaugruppe 44 umfasst eine Mehrzahl von in Umfangsrichtung um die Walzendrehachse A mit vorzugsweise im Wesentlichen gleichem Abstand zueinander angeordneten Versteifungsstreben 62. Jede dieser Versteifungsstreben 62 kann beispielsweise als Rohr ausgebildet sein. Mit einem jeweiligen ersten Endbereich 64 sind die Versteifungsstreben 62 an die Walzenscheibe 18 beispielsweise durch Verschweißung angebunden. Mit einem zweiten Endbereich 66 sind die Versteifungsstreben 62 an den Versteifungsring 30, optional auch an die Innenumfangsfläche 26 des Walzenmantels 12, durch Verschweißung angebunden. Dabei ist in Fig. 6 zu erkennen, dass die Anbindung an die Walzenscheibe 18 nahe einem Innenumfangsbereich 68 derselben erfolgt, so dass die Versteifungsstreben 62 sich ausgehend von der Walzenscheibe 18 in Richtung auf den Versteifungsring 30 zu axial und nach radial außen erstrecken. Die Versteifungsstreben 62 weisen somit zur Walzendrehachse A nicht parallele, diese vorzugsweise jedoch schneidende Strebenlängsachsen S auf. Auch bei der in den Fig. 4 bis 6 dargestellten Ausgestaltungsform wird somit bei einer in sich sehr steif ausgebildeten Verdichterwalze 10 im Walzeninnenraum 14 ausreichend Bauraum für dort anzuordnende Baugruppen belassen.Also in the in the 4 to 6 Compressor roller 10 shown, the roller plate 18 thereof may be constructed with a thickness of more than 40 mm, to thereby already produce a substantial stiffening of the compressor roller 10. The stiffening arrangement 28 provided for a further stiffening again comprises the stiffening ring 30 arranged closer to the axial end region 32 of the roll mantle 12. The stiffening assembly 44 connecting the stiffening ring 30 to the roll disk 18 comprises a plurality of circumferentially around the roll axis of rotation A, preferably substantially the same distance Each of these stiffening struts 62 may be formed, for example, as a tube. With a respective first end portion 64, the stiffening struts 62 are connected to the roller plate 18, for example by welding. With a second end region 66, the stiffening struts 62 are connected to the stiffening ring 30, optionally also to the inner circumferential surface 26 of the roll mantle 12, by welding. It is in Fig. 6 to recognize that the connection to the roll plate 18 is close to an inner peripheral region 68 thereof, so that the stiffening struts 62 extending from the roll plate 18 in the direction of the stiffening ring 30 to axially and radially outwardly. The stiffening struts 62 thus have non-parallel to the roller rotational axis A, but these preferably intersecting strut longitudinal axes S. Also in the in the 4 to 6 illustrated embodiment is thus left at a very stiff trained in itself compressor roller 10 in the roll interior 14 sufficient space for assemblies to be arranged there.

Eine an einem Bodenverdichter vorzusehende geteilte Walze kann zwei derartige in den Fig. 1 bis 6 dargestellte, vorzugsweise zueinander jeweils baugleiche Verdichterwalzen 10 in Richtung einer gemeinsamen Walzendrehachse A aufeinander folgend und mit geringem gegenseitigem Abstand angeordnet umfassen. Im Walzeninnenraum 14 dieser beiden Verdichter 10 können Teile des diesen beiden Verdichterwalzen 10 zugeordneten Walzenantriebs sich befinden, wobei dieser für jede der beiden Verdichterwalzen 10 einen eigenständig betreibbaren Walzenantriebsbereich umfassen kann, so dass jede der beiden Verdichterwalzen 10 vorzugsweise unabhängig von der anderen Verdichterwalze zur Drehung antreibbar ist und dass weiterhin vorzugsweise jede der beiden Verdichterwalzen unabhängig von der jeweils anderen Verdichterwalze in eine Oszillationsbewegung oder/und eine Vibrationsbewegung versetzbar ist. Aufgrund der in sich sehr steifen Bauweise der erfindungsgemäß aufgebauten Verdichterwalzen 10 besteht dabei im Wesentlichen keine Gefahr einer übermäßigen Verformung der Verdichterwalzen.A to be provided on a soil compactor split roller can two such in the Fig. 1 to 6 illustrated, preferably each to each other identical compressor rollers 10 in the direction of a common roller rotation axis A sequentially and arranged arranged at a small mutual distance. Parts of the roller drive associated with these two compressor rollers 10 can be located in the roller interior 14 of these two compressors 10, which can comprise an independently operable roller drive section for each of the two compressor rollers 10 so that each of the two compressor rollers 10 can be driven to rotate independently of the other compressor roller is and that further preferably each of the two compressor rolls is independently of the other compressor roller in an oscillatory movement and / or a vibratory movement displaceable. Due to the inherently very rigid construction of the compressor rollers 10 constructed according to the invention, there is substantially no risk of excessive deformation of the compressor rollers.
