Description
Die vorliegende Erfindung betrifft eine Bodenverichtungsvorrichtung mit Vibrationsantrieb, wobei der Vibrationsantrieb zur Erzeugung einer gerichteten Schwingungsbewegung wenigstens zwei auf gegensinnig synchron rotierenden Unwuchterregerwellen angeordnete Unwuchten aufweist. Derartige Bodenverdichtungsvorrichtungen bestehen insbesondere aus Straßenwalzen; dasselbe Prinzip läßt sich aber auch bei Plattenrüttlern anwenden.The present invention relates to a Bodenverichtungsvorrichtung with vibration drive, wherein the vibration drive for generating a directional vibration movement has at least two arranged in opposite directions synchronously rotating unbalance exciter waves imbalances. Such soil compaction devices consist in particular of road rollers; The same principle can also be applied to plate vibrators.
Bekannte Bodenverdichtungsvorrichtungen weisen beispielsweise zwei horizontal nebeneinander angeordnete Unwuchterregerwellen auf, die durch Änderung ihrer Phasenlage das Erzeugen verschiedener Verdichtungs- und Antriebsrichtungen ermöglichen. Da die beiden Erregerwellen jedoch unterschiedliche Drehrichtungen aufweisen, müssen sie in ausreichendem Abstand voneinander angeordnet werden, um eine Kollision der Unwuchten zu verhindern. Dies führt zu einem entsprechend großen Platzbedarf.Known ground compaction devices have, for example, two imbalance exciter shafts arranged horizontally next to one another which, by changing their phase position, make it possible to generate different compaction and drive directions. However, since the two excitation shafts have different directions of rotation, they must be arranged at a sufficient distance from each other to prevent a collision of the imbalances. This leads to a correspondingly large space requirement.
Daneben sind Bodenverdichtungsvorrichtungen bekannt, die drei Unwuchterregerwellen aufweisen, welche nicht nebeneinander, sondern fluchtend hintereinander angeordnet sind, wobei die beiden äußeren Unwuchterregerwellen gleichsinnig drehen und sie durch die mittlere Unwuchterregerwelle, die als Hohlwelle ausgeführt ist, miteinander verbunden sind. Damit allerdings die mittlere Unwuchterregerwelle die erforderliche gegensinnige Drehrichtung erhält, muß sie zur Drehrichtungsumkehr über eine separate Getriebeanordnung an eine der beiden äußeren Unwuchterregerwellen angekoppelt sein. Auch dies macht einen hieran angepaßten vergrößerten Bauraum erforderlich.In addition, soil compacting devices are known which have three unbalance exciter shafts, which are not arranged side by side, but in alignment one behind the other, wherein the two outer unbalance exciter shafts rotate in the same direction and they are interconnected by the middle unbalance exciter shaft, which is designed as a hollow shaft. However, so that the average unbalance exciter shaft receives the required opposite direction of rotation, it must be reversed by a separate gear arrangement to one of the two be coupled outer unbalance exciter shafts. This also makes an adapted enlarged space required.
Bekannte Vibrationsantriebe finden sich in
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die bekannten Bodenverdichtungsvorrichtungen hinsichtlich der Anordnung ihrer Unwuchterregerwellen derart zu verbessern, daß sie sich durch optimierte Einbauverhältnisse auszeichnen.The present invention has for its object to improve the known soil compacting devices in terms of the arrangement of their unbalance exciter shafts so that they are characterized by optimized installation conditions.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß beide Unwuchten zweigeteilt sind und deren Unwuchtteile jeweils zwei separaten gleichsinnig zueinander rotierenden Erregerwellen zugeordnet sind derart, daß die beiden Unwuchtteile der ersten Unwucht auf axial miteinander fluchtenden Erregerwellen angeordnet sind, daß zwischen den beiden Erregerwellen die zweite Unwucht vorgesehen ist, und daß die beiden Unwuchtteile der zweiten Unwucht auf zueinander parallelen und sich versetzt zu den Erregerwellen der ersten Unwucht erstreckenden Erregerwellen angeordnet sind.This object is achieved in that the two imbalances are divided into two and their unbalance parts are assigned to each separate two mutually in the same direction exciter shafts such that the two imbalance parts of the first imbalance are arranged on axially aligned excitation shafts that provided the second imbalance between the two exciter shafts is, and that the two unbalance parts of the second imbalance on mutually parallel and offset from the exciter waves of the first unbalance extending exciter waves are arranged.
Zunächst einmal ergibt sich hierdurch der Vorteil, daß die Gesamtfliehkraft der Unwuchten auf vier Wellen verteilt wird, und somit die einzelnen Unwuchterregerwellen über entsprechend kleinere Lager gelagert werden können. Diese kleineren Lager führen vor allem dazu, daß höhere Grenzdrehzahlen bis hin zu 70 Hz realisierbar sind, was ein verbessertes Arbeitsverhalten der Bodenverdichtungsvorrichtung ergibt. Durch die Vergrößerung der Lageranzahl wird es außerdem möglich, größere Unwuchten zu installieren, wodurch sich die Verdichtungsarbeit ebenfalls entsprechend verbessern läßt.First of all, this results in the advantage that the total centrifugal force of the unbalance is distributed to four waves, and thus the individual unbalance exciter waves can be stored on correspondingly smaller bearings. Above all, these smaller bearings mean that higher limit speeds of up to 70 Hz can be achieved, which results in improved working behavior of the soil compaction device. By increasing the number of bearings, it is also possible to install larger imbalances, whereby the compression work can also be improved accordingly.
Eine Verbesserung der Einbauverhältnisse ergibt sich dadurch, daß auch die parallelen Erregerwellen der zweiten Unwucht, die gleichsinnig umlaufen, anders als beim Stand der Technik platzsparend und kollisionsfrei nebeneinander angeordnet werden können. Vor allem ermöglicht die erfindungsgemäße Bodenverdichtungsvorrichtung aber eine Bauraumoptimierung, indem alle vier Erregerwellen, also selbst die gegensinnig umlaufenden Erregerwellen so aneinander angekoppelt werden können, daß auf ein separates Getriebe zur Drehrichtungsumkehr verzichtet werden kann. Hierzu ist es erforderlich, daß die Erregerwelle eines der beiden Unwuchtteile der ersten Unwucht direkt an die Erregerwelle zumindest eines Unwuchtteils der zweiten Unwucht angekoppelt ist, daß die Erregerwellen beider Unwuchtteile der zweiten Unwucht direkt an die Erregerwelle eines Unwuchtteils der ersten Unwucht angekoppelt sind, und daß die Antriebswelle des Vibrationsantriebes die einem Unwuchtteil der ersten Unwuchtteil der ersten Unwucht zugeordnete Erregerwelle antreibt, diese Erregerwelle, die den beiden Unwuchtteilen der zweiten Unwucht zugeordneten Erregerwellen antreibt, und eine der beiden Erregerwellen der zweiten Unwucht die dem anderen Unwuchtteil der ersten Unwucht zugeordnete Erregerwelle antreibt. Somit kann auch auf eine separate Lagerung der zugehörigen Getriebezahnräder verzichtet werden kann. Schließlich ermöglicht die direkte Kopplung der vier Unwuchterregerwellen aber auch die Verwendung vieler Gleichteile pro Unwucht, indem beispielsweise jeweils die Unwuchterregerwellen, die zugehörigen Zahnräder zur Rotationsübertragung und die Unwuchtgewichte der ersten Unwucht gleich ausgeführt sein können; gleiches gilt auch für die zweite Unwucht. Dies führt zu einer Reduzierung der Einzelteilkosten und des zugehörigen Lagerhaltungs- und Wartungsaufwandes.An improvement in the installation conditions results from the fact that the parallel exciter waves of the second imbalance, which rotate in the same direction, unlike the prior art space-saving and collision-free can be arranged side by side. Above all, the ground compaction device according to the invention, however, allows a space optimization by coupling all four excitation shafts, that is to say even the oppositely circulating exciter shafts, to one another can be that can be dispensed with a separate gear to reverse the direction of rotation. For this purpose, it is necessary that the exciter shaft of one of the two imbalance parts of the first imbalance is coupled directly to the exciter shaft at least one imbalance part of the second imbalance, that the excitation shafts of both imbalance parts of the second imbalance are coupled directly to the exciter shaft of an imbalance part of the first imbalance, and that the drive shaft of the vibration drive which drives an unbalance part of the first unbalance part of the first unbalance associated exciter shaft, this exciter shaft which drives the two unbalanced parts of the second unbalance associated exciter, and drives one of the two exciter waves of the second unbalance the other unbalance part of the first unbalance associated exciter shaft. Thus, can be dispensed with a separate storage of the associated gear wheels. Finally, the direct coupling of the four unbalance excitation shafts but also allows the use of many common parts per imbalance, for example, by each of the unbalance exciter, the associated gears for rotation transmission and the imbalance weights of the first imbalance can be made equal; The same applies to the second imbalance. This leads to a reduction of the item costs and the associated storage and maintenance costs.
Um die Fliehkräfte hinsichtlich ihrer Größe und Richtung ändern zu können, empfiehlt es sich, wenn die Erregerwellen beider Unwuchten in einem gemeinsamen Gestell gelagert sind, das um eine zu ihnen parallele Achse verschwenkbar und in der gewünschten Schwenkposition arretierbar ist, wobei es ausgehend von einer Bezugsposition mit vertikal übereinander angeordneten Erregerwellen der zweiten Unwucht beidseitig, insbesondere bis etwa 90° verstellbar sein sollte.In order to change the centrifugal forces in terms of their size and direction, it is recommended that the exciter waves of both unbalances are mounted in a common frame which is pivotable about an axis parallel to them and lockable in the desired pivot position, starting from a reference position with vertically superposed exciter waves of the second imbalance on both sides, in particular should be adjustable to about 90 °.
Hierbei ist es zweckmäßig, wenn die Einstellung der Position der Erregerwellen in Abhängigkeit von der Fahrtrichtung vorgenommen wird. Dadurch unterstützt ein Anteil der in der Bodenverdichtungsvorrichtung erzeugten Schwingungskraft den Fahrantrieb der Bodenverdichtungsvorrichtung, anstatt ihm entgegenzuwirken.It is expedient if the adjustment of the position of the exciter shafts in dependence on the direction of travel is made. As a result, a portion of the vibration force generated in the soil compaction device supports the traction drive of the soil compacting device, instead of counteracting it.

In Figur 1 ist der Aufbau eines Schwingungserregers einer Bodenverdichtungsvorrichtung dargestellt, wobei insbesondere vier Unwuchterregerwellen 1, 2, 3, 4 erkennbar sind, die über eine Antriebswelle 5 mit einem Vibrationsantrieb 6 verbunden sind. Jede Unwuchterregerwelle 1 bis 4 weist ein zugehöriges Unwuchtgewicht 11, 12, 13, 14 auf, wobei die Unwuchtgewichte 11 und 14 der Unwuchterregerwellen 1 und 4 einerseits und die Unwuchtgewichte 12 und 13 der Unwuchterregerwellen 2 und 3 andererseits jeweils in gleicher Ausrichtung zueinander angeordnet sind, um hierduch eine Addition zu einer ersten Unwucht A bzw. zweiten Unwucht B zu ermöglichen, wobei beide Gesamtunwuchten jeweils gleich große Fliehkräfte erzeugen.1 shows the structure of a vibration exciter of a soil compaction device, wherein in particular four unbalance exciter
Die Unwuchterregerwelle 1, die im Gegenuhrzeigersinn umläuft, weist stirnseitig ein Zahnrad 21 auf, das mit einem Zahnrad 22 der Unwuchterregerwelle 2 und einem Zahnrad 23 der Unwuchterregerwelle 3 in Eingriff befindlich ist und beide Unwuchterregerwellen hierdurch in entgegengesetzter Drehrichtung, also im Uhrzeigersinn antreibt. Die Unwuchterregerwelle 3 weist an der dem Zahnrad 23 gegenüberliegenden Stirnseite ein weiteres Zahnrad 23a auf, das mit einem Zahnrad 24 der Unwuchterregerwelle 4 kämmt und die Erregerwelle 4 in wiederum entgegengesetzter, also in gleicher Drehrichtung wie die Erregerwelle 1 antreibt.The unbalance exciter shaft 1, which rotates in the counterclockwise direction, has a
Hieraus resultiert folglich eine direkte Kopplung aller vier Erregerwellen, ohne daß ein zusätzlicher Getriebezug erforderlich ist, und ohne daß außerdem die mittlere Erregerwelle als Hohlwelle ausgeführt sein muß. Hierdurch ergibt sich der bereits erwähnte Vorteil, daß viele Gleichteile verwendet werden können, wie unschwer aus Figur 1 erkennbar ist. Der Schwingungserreger der Bodenverdichtungsvorrichtung, also die vier Erregerwellen mitsamt ihren Unwuchten sind zur Richtungs- und Größenänderung der Fliehkräfte in einem Gestell 7 gelagert, das über einen Schwenkmotor 8 mitsamt den darin gelagerten Erregerwellen verschwenkt werden kann. Das Gestell 7 ist wiederum im Beispiel aus Figur 1 in einer Walzenbandage 9 einer Straßenwalze derart angeordnet, daß das Gestell unabhängig von der Fahrbewegung der Bandage in der jeweiligen Schwenkposition verbleibt.Consequently, this results in a direct coupling of all four exciter waves, without an additional gear train is required, and without also the middle exciter shaft must be designed as a hollow shaft. This results in the already mentioned advantage that many identical parts can be used, as can be readily recognized from FIG. The vibration exciter of the soil compacting device, so the four exciter waves including their imbalances are stored for direction and size change of the centrifugal forces in a
In Figur 2 ist die Bezugsposition für das Verschwenken des Gestells dargestellt, bei der das Gestell nicht gegenüber der Walzenbandage verschwenkt ist und die beiden Erregerwellen 2 und 3 der zweiten Unwucht vertikal übereinander angeordnet sind. Demgegenüber ist in Figur 3 eine Position des Gestells 7 dargestellt, bei der diese um 45° gegenüber der Bezugsposition verschwenkt ist.In Figure 2, the reference position for the pivoting of the frame is shown, in which the frame is not pivoted relative to the roll drum and the two
In den Figuren 2 und 3 sind jeweils zwei die Funktion der Unwuchten verdeutlichende Phasen dargestellt, nämlich eine erste Phase, bei der sich die Fliehkräfte der Unwuchten - in Horizontalrichtung bei Figur 2 und um 45° nach links unten bei Figur 3 - gerade aufheben und bei der die Unwuchten einerseits und die den Fliehkräften entsprechenden Pfeile andererseits mit durchgezogenen Linien dargestellt sind; in der zweiten Erregerphase, die mit gestrichtelten Linien angedeutet ist, addieren sich die Fliehkräfte, so daß eine Gesamtfliehkraft F entsteht, die in Figur 2 vertikal nach unten und in Figur 3 um 45° nach rechts unten gerichtet ist.FIGS. 2 and 3 each show two phases which illustrate the function of the imbalances, namely a first phase in which the centrifugal forces of the imbalances-in the horizontal direction in FIG. 2 and by 45 ° in the lower left in FIG the unbalances on the one hand and the arrows corresponding to the centrifugal forces on the other hand are shown by solid lines; in the second excitation phase, which is indicated by dashed lines, the centrifugal forces add up, so that a total centrifugal force F arises, which is directed vertically downwards in FIG. 2 and 45 ° downwards in FIG.
Zusammenfassend bietet die vorliegenden Erfindung somit den Vorteil, daß die Gesamtunwucht auf insgesamt vier Erregerwellen verteilt werden kann, wodurch sich zum einen die Grenzdrehzahlen erhöhen und zum anderen die Fliehkraft durch Verwendung schwererer Unwuchtgewichte vergrößern läßt. Schließlich zeichnet sich die erfindungsgemäße Bodenverdichtungsvorrichtung durch optimierte Einbauverhältnisse der zugehörigen Erregerwellen aus.In summary, the present invention thus has the advantage that the total imbalance can be distributed to a total of four exciter waves, which on the one hand increase the limit speeds and on the other hand can increase the centrifugal force by using heavier imbalance weights. Finally, the soil compacting device according to the invention is distinguished by optimized installation conditions of the associated exciter shafts.
