Description
Fliehkrafterregeraggregat für Schwingmaschinen, vorzugsweise Vibrationsrammen Die Erfindung betrifft ein Fliehkrafterreger- aggregat für Schwingmaschinen, vorzugsweise Vibra- tionsrammen, bei dem gegensinnig synchron um laufende Schwungmassen miteinander linear gerich tete Wechselkräfte erzeugen.
Fliehkrafterreger dieser Art sind für Schwing maschinen, insbesondere Vibrationsrammen, bereits mehrfach vorgeschlagen worden. Allgemein hat man die Schwungmassen der bekannten Erreger in einem Gehäuse gelagert, das mit der Schwingmaschine zu einer konstruktiven Einheit zusammengefasst ist. Bei dieser Bauweise können die Schwungmassenerreger bezüglich ihrer maximal möglichen Kraftentfaltung kaum erweitert werden, weil sich die Schwungmassen wegen des begrenzten Gehäuseinnenraumes nur un wesentlich vergrössern lassen.
Durch die Erfindung soll ein in seiner Schwing leistung veränderbares Fliehkrafterregeraggregat ge schaffen werden. Das erfindungsgemässe Aggregat ist gekennzeichnet durch mehrere Erregereinheiten, die in solcher Lage lösbar miteinander verbunden sind, dass ihre Kraftvektoren in gemeinsamer Wirkungs linie verlaufen.
Vorteilhaft ist der Antriebsmotor des Aggregates an einer endständigen Erregereinheit befestigt.
Eine zweckmässige Ausführung besteht darin, dass eine der endständigen Erregereinheiten mit Mitteln zum Anschluss des Aggregates an eine durch Kraft impulse zu betreibende Schwingmaschine oder eine Aufnahmevorrichtung zum Einspannen der einzu treibenden bzw. herauszuziehenden Raumkörper ver sehen ist.
Das erfindungsgemässe Erregeraggregat ist wegen seiner schmalen Bauform als Antriebsmittel, insbeson dere für Vibrationsrammen, geeignet.
Die Erfindung wird anhand eines in einer Vor deransicht veranschaulichten, schematisch dargestell ten Ausführungsbeispieles näher beschrieben. Die Erregereinheiten 1, 2, 3 mit den Schwung- massenpaaren la, 1b, 2a, <I>2b, 3a,</I> 3b sind mit Hilfe der Schrauben 4 zu dem erfindungsgemässen Erreger aggregat zusammengefügt. Zu diesem Erregeraggre gat gehört der Antriebsmotor 5, der mittels der Schrauben 6 auf der endständig oberen Erreger einheit befestigt ist.
Die Schwungmassenpaare stehen mittels der Zahnräder 1c, 1d, <I>2c, 2d, 3c, 3d</I> und der Ketten 7', 7" miteinander und mittels der Kette 7 mit dem Antriebsmotor in Verbindung. Ihre Dreh richtung ist durch Pfeile angedeutet. An der end- ständigen unteren Erregereinheit ist beispielsweise eine Aufspannvorrichtung 8 für einen Rammkörper 9 mit Hilfe der Schrauben 10 befestigt.
Centrifugal exciter unit for vibrating machines, preferably vibration rammers The invention relates to a centrifugal force exciter unit for vibrating machines, preferably vibrating rams, in which opposing synchronous rotating masses generate linearly directed alternating forces with one another.
Centrifugal exciters of this type have been proposed several times for vibrating machines, especially vibration rammers. In general, the centrifugal masses of the known exciters are stored in a housing that is combined with the oscillating machine to form a structural unit. With this design, the centrifugal mass exciter can hardly be expanded in terms of their maximum possible force development, because the centrifugal masses can only be increased significantly due to the limited interior space of the housing.
The invention is intended to create a variable centrifugal force exciter unit in its vibration performance. The unit according to the invention is characterized by several excitation units which are releasably connected to one another in such a position that their force vectors run in a common line of action.
The drive motor of the unit is advantageously attached to a terminal exciter unit.
An expedient embodiment is that one of the terminal excitation units is provided with means for connecting the unit to a vibrating machine to be operated by force pulses or a receiving device for clamping the space bodies to be driven or extracted.
The exciter unit according to the invention is suitable because of its narrow design as a drive means, in particular for vibration ramming.
The invention is described in more detail with reference to an illustrated in a front view, schematically dargestell th embodiment. The exciter units 1, 2, 3 with the centrifugal mass pairs la, 1b, 2a, <I> 2b, 3a, </I> 3b are assembled with the aid of the screws 4 to form the exciter unit according to the invention. To this Erregeraggre gat includes the drive motor 5, which is attached by means of the screws 6 on the terminal upper exciter unit.
The centrifugal mass pairs are connected to one another by means of the gears 1c, 1d, <I> 2c, 2d, 3c, 3d </I> and the chains 7 ', 7 "and to the drive motor by means of the chain 7. Their direction of rotation is indicated by arrows A clamping device 8 for a ram body 9, for example, is attached to the terminal lower exciter unit with the aid of the screws 10.
