Description

Rüttler für Beton- ünd Massenverdichtung Es ist bekannt, einen Bauteil von Schwingungen dadurch zu befreien, daß an ihm Gegenschwingungen erzeugt werden, deren Frequenz gleich, aber entgegengesetzt der Erregerschwingungen ist. Es wird dann ein Zustand erreicht, daß keine Schwingungen mehr in dem ganzen Gerät vorhanden sind.Vibrators for concrete and mass compaction It is known to have a component to free from vibrations by generating counter-vibrations on it, whose frequency is the same but opposite to the excitation vibrations. It will then a state is reached that no more vibrations are present in the entire device are.

Im Gegensatz dazu müssen bei Rüttlern für Beton- und 'Massenverdichtung an ein und derselben Maschine an der Rüttelflasche starke Nutzschwingungen, und zwar senkrecht zur Längsrichtung des Gerätes, auftreten, die ja die Verdichtungsarbeit leisten sollen, während solche Schwingungen an dem Antriebsmotor und den Bedienungshandgriffen äußerst schädlich sind und unangenehm- empfunden werden. Es ergibt sich also die Aufgabe, daß an einem Gerät ein Teil starke Schwingungen ausüben soll, der mit einem anderen Teil verbunden ist, der keine Schwingungen haben soll. Beide Teile müssen jedoch so verbunden sein, daß der schwingende Teil durch den ruhenden bewegt und gelenkt werden kann. Diese Aufgabe wird dadurch gelöst, daß an dem umlaufenden Teil zur Beruhigung der in Griffnähe befindlichen Stelleneine oder mehrere Unwuchtmassen entsprechend angebracht werden. Nach der Erfindung ist die Rüttelflasche i, welche durch die exzentrisch gelagerte Masse 2 in starke Schwingungen versetzt wird, mit dem Antriebsmotor 3 und dem Bedienungsgriff 6 durch ein biegungselastisches Rohr 5 verbunden. In diesem Rohr läuft die Antriebswelle zwischen Motor 3 und Unwuchtmasse 2. Durch die Zusatzmasse q. in Abb. i können Transversalschwingungen oder bei mehreren Zusatzmassen 9 nach Abb. 2, die an der Motorwelle gegenüber, aber nicht in einer zur Rüttlerwelle senkrechten Ebene liegen, Kippschwingungen erzeugt werden .oder eine Mischung von beiden Schwingungsarten, welche die von der Rüttelflasche i über das elastische Rohr 5 auf den Motor 3 und Handgriff 6 übertragenen Schwingungen aufheben.In contrast, vibrators for concrete and 'mass compaction Strong useful vibrations on one and the same machine on the shaker bottle, and Although it is perpendicular to the longitudinal direction of the device, it does the compression work should perform, while such vibrations on the drive motor and the operating handles are extremely harmful and are perceived as unpleasant. So it results Task that a part should exert strong vibrations on a device with a other part is connected, which should not have any vibrations. Both parts must however, be connected in such a way that the vibrating part moves through the resting part and can be steered. This object is achieved in that on the rotating part one or more unbalanced masses to calm the areas within reach be attached accordingly. According to the invention is the vibrating bottle i, which is set in strong vibrations by the eccentrically mounted mass 2, with the drive motor 3 and the operating handle 6 by a flexible tube 5 connected. The drive shaft runs in this tube between the motor 3 and the unbalanced mass 2. The additional mass q. in Fig. i can be transverse oscillations or with several Additional masses 9 according to Fig. 2, which are on the opposite side of the motor shaft, but not in one be perpendicular to the vibrator shaft, tilting vibrations are generated. or a mixture of both types of vibration, which the vibrating bottle i over the elastic tube 5 on the motor 3 and handle 6 transmitted vibrations lift.
