Description

Beschreibung Zie bfitrifft eine) coutinuierlicht während des Lgu. fesverstellbare Hüttelunwucht, insbesondere für Straßenrutt- ler zur rrelelunc einer Vor-und Rückwärtebewegung bei gleich- zeitifrVerdichtungearbeit. RUttelunwuchten mit kontinuierlicher Verstellmöglichkeit sind bereits beannt In den deutschen Patentschriften 532 828, 632 992 und 677 989 sind Ausfuhrunebeispiele beschrieben. Auch Cie 2 517 587 hat eine solche Unwucht zumeenstandt s handelt sich dabei aber atets um mechani- scheTertlllieder (Zahnräder, Zahnstangen, usw.), die einem verbb'iltniß'Rta. Uiß hohem Verschleiß unterliegen. Auch ist es wegen der meist sehr gro'en bmeasungen nicht mölich, bei- apieliae einpR gut arbeitenden Grabenverdichter mit einer Arbeitsbreite von unter 400 mm zu bauen, der kontinuierlich von einer Vorwärts-in eine Ruckwartsbewegung umgesteuert wer- den kann und umgekehrt. Der rf1ndunb liegt die Aufgabe zugrunde eine Rüttelunwuoht zu schaffen, die kontinuierlich mit hydraulischen Utteln ver- stellt weiden kann und dabei eine sehr geringe Konstruktion- breite aufseist. In der Zeichnung ist als Auefuhrungabeispiel der Erfindung ei- ne zur verwendun bei Mraßen-oder Grabenrüttlermpschinen ge- eignete inrichtun zur Erzeugung mechanischer Schwingungen durch zwei gegeneinander unlaufende, hydraulisch kontinuier- lieh zueinander in der Winkellage verstellbare Massen dargestellt. @ie besteht aus einer Antriebscheibe 1, die ebenso wie das Zahnrad 2 und die Unwuchtscheiben 3 und 4 auf der @elle 5, welche bei 6 und 7 in einem Gehäuse 8 gelagert ist befestigt ist. Auf einer bei 9 und 10 gelagerten welle 11 sind zwei weitere Unwuchtscheiben 12 und 13 befestigt. In das Zahnrad 14, das auf der @elle 11 drehbar gelagert ist, eind zwei Druckkammern 15 und 16 eingearbeitet. Ein Radialschieber 17 ist mit der Welle 11 fest verbunden. Die Druckölzuführungen 18 und 19 sind bei 20 und 21 fest ait dem Gehäuse 6 verbunden. Die rotierenden Unwuohtscheiben 3, 4, 12, 13 erzeugen je nach ihrer'inkellage zueinander Schwingungen bestimmter Art und lichtung. Je nachdes, ob Drucköl in die Druckkammer 15 oder 16 eingeführt wird, werden aber den Radialachieber 17 und die Welle 11 die Unwuchtscheiben 12 und 13 zu den Unwuchten'und 4 in ihrer Winkellage kontinuierlich verstellt und dadurch Schwingungen gewünschter Art und Richtung zur erzielung einer Vor-undRückwärtsbewegung erreichte description Zie bfits a) coutinuous light during the Lgu. adjustable bucket unbalance, especially for road slurry ler to relelunc a forward and backward movement with equal Time for compaction work. Vibration imbalances with continuous adjustment are already announced in German patents 532 828, 632 992 and 677 989 are exemplary embodiments described. Cie 2 517 587 also has such an imbalance at least it is a matter of mechanical ScheTertlllieder (gears, racks, etc.), the a verbb'iltniß'Rta. They are subject to high wear and tear. Also is because of the usually very large dimensions, it is not possible to apieliae a well-working trench compactor with a Build working widths of less than 400 mm, continuously be reversed from a forward to a backward movement can and vice versa. The rf1ndunb is based on the task of a Vüttelunwuoht that are continuously connected with hydraulic shackles is able to graze and at the same time has a very low construction width on top. In the drawing, an example of the invention is shown ne for use with ground or trench vibrator machines Suitable equipment for generating mechanical vibrations by two hydraulically continuous borrowed to each other in the angular position shown masses adjustable. It consists of a drive pulley 1 which, like the gear wheel 2 and the unbalance disks 3 and 4, is fastened to the shaft 5, which is mounted in a housing 8 at 6 and 7. On a shaft 11 supported at 9 and 10, two further unbalance disks 12 and 13 are attached. In the gear 14, which is rotatably mounted on the shaft 11, two pressure chambers 15 and 16 are incorporated. A radial slide 17 is firmly connected to the shaft 11. The pressure oil feeds 18 and 19 are firmly connected to the housing 6 at 20 and 21. The rotating Unwuohtplatten 3, 4, 12, 13 generate depending on their 'angular position to each other vibrations of a certain type and clearing. Depending on whether pressure oil in the pressure chamber 15 or 16 is introduced, but the Radialachieber 17 and the Shaft 11 continuously adjusts the unbalance disks 12 and 13 relative to the unbalances and 4 in their angular position and thereby vibrations of the desired type and direction to achieve a Back and forth movement reached
