Abstract
Description
Die vorliegende Erfindung betrifft eine Siebmaschine zum Entwässern und/oder Klassieren von körnigen Stoffen wie Kies, Kohle oder Erz, mit einem Siebrahmen, der an einem Maschinengestell gehalten ist, und mit einem elliptischen Schwingungsantrieb mit zwei Exzenterwellen, die unterschiedliche Unwuchten aufweisen und die synchron und gegenläufig mittels des Antriebs angetrieben werden. Eine derartige Siebmaschine ist aus US 3 226 989 bekannt.The present invention relates to a screening machine for dewatering and / or classifying granular Materials such as gravel, coal or ore, with one Screen frame held on a machine frame is, and with an elliptical vibration drive with two eccentric shafts, the different imbalances and synchronously and in opposite ways be driven by the drive. Such a screening machine is known from US 3,226,989.
Eine Siebmaschine mit diesen Merkmalen ist aus der Druckschrift "Siebmaschinen mit elliptischer Schwingung und dynamischem Antrieb", Aufbereitungs-Technik Nr. 7/1982, Seiten 367 bis 372, bekannt, die einen Linearantrieb zum Entwässern und Klassieren von Kies, Sand und dergleichen aufweist. Bei dieser Maschine sitzen an zwei Wellen die Unwucht erzeugenden Massen. Diese Exzenterwellen sind in einem Winkel von 40° bis 50° zur Hauptschwingungsrichtung angeordnet und über Zahnradgetriebe synchronisiert. Dabei läßt sich die Hauptschwingweite bei gleichen oder ungleichen Massen in ihrer linearen oder elliptischen Form und Größe verändern. Der wesentlichste Nachteil dieser bekannten Ausführungsform besteht darin, daß beim Synchronlauf sehr hohe Zahnflankenkräfte in positiver und negativer Richtung einhämmern, wodurch die Laufruhe beeinträchtigt ist und auch eine erhöhte Temperatur im Getriebe auftritt. Ein weiterer wesentlicher Nachteil besteht darin, daß ein teures Sondergetriebe gebraucht wird, dessen Störanfälligkeit und Ausfallquote sehr hoch ist. Beim Verändern des Exzenterwellenabstandes ist darüber hinaus ein anderes Getriebe notwendig.A screening machine with these features is out the publication "screening machines with elliptical Vibration and dynamic drive ", treatment technology No. 7/1982, pages 367 to 372, which is a linear actuator for draining and classifying of gravel, sand and the like. At this Machine sit on two waves causing imbalance Masses. These eccentric shafts are at an angle from 40 ° to 50 ° to the main vibration direction arranged and synchronized via gear transmission. Here, the main swing can be the same or unequal masses in their linear or elliptical Change shape and size. The most essential Disadvantage of this known embodiment is in that during synchronous running very high tooth flank forces hammering in positive and negative direction, whereby the smoothness is impaired and also a increased temperature in the transmission occurs. Another major disadvantage is that an expensive Special gear is needed, its susceptibility and default rate is very high. When changing the Eccentric shaft spacing is also another Transmission necessary.
Aus der DE-26 30 458 A1 oder der DE-78 11 967 U1 ist weiterhin ein antreibbares Vibrationsgetriebe bekannt, bei dem ein Getriebekasten oberhalb des Siebkastens auf die Seitenwände und eine Traverse aufgeschraubt ist. Über eine mittlere Welle werden zwei seitliche Unwuchtgetriebe angetrieben, die in der Lage verbleiben, in der sie im Getriebe angeordnet sind. Der wesentliche Nachteil dieser bekannten Ausführungsform besteht darin, daß der Antrieb extrem außerhalb des Schwerpunktes des Siebkastens angebracht wird und sich dadurch sehr hohe Bauhöhen der Maschine ergeben. In beiden bekannten Siebmaschinen befinden sich die Unwuchten, bezogen auf die radiale Verbindungslinie der Exzenterwellen, nicht einander gegenüber, sondern zueinander um einen Winkel von weniger als 180° versetzt.From DE-26 30 458 A1 or DE-78 11 967 U1 is still a drivable vibration gear known in which a gear box above the Sieve box on the side walls and a crossbar is screwed on. About a middle wave become two lateral unbalance driven, capable of remain in which they are arranged in the transmission. Of the significant disadvantage of this known embodiment is that the drive is extremely outside the center of gravity of the sieve box is attached and thereby very high construction heights of the machine result. Located in both known screening machines the unbalance, based on the radial connecting line the eccentric shafts, not opposite each other, but to one another at an angle of less offset by 180 °.
Aus der DE-23 56 542 B2 ist eine Siebmaschine mit einem Drei-Wellen-Antrieb bekannt, bei der die Hauptschwingrichtung durch die Achse der dritten, mittig angeordneten Welle verläuft.From DE-23 56 542 B2 is a screening machine with a three-shaft drive known in which the main swing direction through the axis of the third, centered arranged wave runs.
Der Erfindung liegt die Aufgabe zugrunde, einen Schwingungsantrieb der eingangs genannten Art so auszubilden, daß unter Einhaltung einer geringen Bauhöhe der Maschine verschiedene Schwingungsbilder eingestellt und die Schwingrichtung verändert werden kann, wobei insbesondere auch Betriebsgeräusche und Temperaturen vermindert werden.The invention is based on the object, a Vibration drive of the type mentioned so form that while maintaining a low height the machine different vibration patterns set and the swing direction to be changed can, in particular also operating noise and Temperatures are reduced.
Diese Aufgabe wird erfindungsgemäß durch eine Siebmaschine mit den Merkmalen des Anspruchs 1 gelöst. Die Resultierende der Massenkräfte der Unwuchten greift so nahe am Massenschwerpunkt der Siebmaschine an, daß das durch die Abweichung hervorgerufene Wippen der Siebmaschine deren Eigendämpfung nicht übersteigt.This object is achieved by a Sieving machine with the features of claim 1 solved. The resultant of the mass forces of the Imbalance reaches so close to the center of gravity of the screening machine that caused by the deviation Rockers of the screening machine Self-damping does not exceed.
Eine vorteilhafte Ausführungsform besteht darin, daß die Massenkräfte der Unwuchten einstellbar sind.An advantageous embodiment is that the inertial forces of the imbalances are adjustable.
Es wird weiterhin vorgeschlagen, däß die Keii-oder Zahnriemen an einer Motorkonsole stationär zwischen den Motoren angebracht sind.It is further suggested that the Keii or Timing belt on a motor console stationary between the motors are attached.
Eine vorteilhafte Ausführungsform sieht vor, daß die Exzenterwellen über Vorgelege angetrieben sind, wobei die Riemen zwischen den Vorgelegewellen angebracht sind.An advantageous embodiment provides that the eccentric shafts are driven via countershaft, the straps being mounted between the countershafts are.
Weiterhin wird vorgeschlagen, daß die Schwingrichtung und Form der Unwuchtmasse in Größe und Winkellage zur Hauptschwingrichtung durch manuelle oder elektrische Verstellung von einer oder beiden Exzenterwellen veränderbar ist.Furthermore, it is proposed that the oscillation direction and shape of imbalance mass in size and Angular position to main swing direction by manual or electrical adjustment of one or both Eccentric waves is changeable.
Schließlich ist es vorteilhaft, daß an der Motorkonsole eine oder zwei Synchronwellen gelagert sind, über. die die Gelenkwellen der Motoren mittels der Riemen verbunden sind.Finally, it is advantageous that on the engine console one or two synchronous shafts are stored, about. Drive shafts of engines by means of belts are connected.
Die Erfindung bringt insbesondere den Vorteil, daß die Synchronisationskräfte auf die Riemen nahe Null sind, so daß ein Flattern des Antriebes entfällt. Ein weiterer wesentlicher Vorteil besteht darin, daß nach dem Anfahren der kleinere Motor ausgeschaltet werden kann und die Restkräfte der kleineren Unwuchtmassen vom großen Motor übernommen werden, woraus sich eine Energieeinsparung ergibt. Eine solche Energieeinsparung ergibt sich auch durch die verminderten Temperaturen und Laufgeräusche. Bei einer Achsabstandsänderung der Exzenterwellen sind keine neuen Antriebsteile (z.B. Getriebe) erforderlich, wobei auch der Antrieb insgesamt vereinfacht ist, indem keine zusätzlichen Antriebsaggregate oder eine Turbokupplung erforderlich sind. Die verwendeten Riemen bewirken durch ihre Federwirkung eine Dämpfung. Umweltverschmutzungen, wie beispielsweise durch Ölaustritt lassen sich vermeiden.The invention brings in particular the advantage that the synchronization forces on the belts are close to zero, so that a flutter of the Drive is eliminated. Another significant advantage is that after starting the smaller Engine can be turned off and the residual forces the smaller imbalance masses taken over by the big engine which results in energy savings results. Such an energy saving also results due to the reduced temperatures and running noise. With a change in the axle distance of the eccentric shafts are no new drive parts (eg gearbox) required, whereby the drive is simplified as a whole is by adding no additional drive units or a turbo coupling are required. The used Belts cause by their spring action a Damping. Pollution, such as Oil leakage can be avoided.

zwei Unwuchten 7, 8, die über Unwuchtwellen oder
Exzenterwellen 14, 15 am Siebkasten 1 gelagert sind.
Der Antrieb dieser Exzenterwellen 14, 15 erfolgt über
Gelenkwellen 5, 6, die von Motoren 9, 10 angetrieben
werden, die an einer stationären Motorkonsole gehaltert
sind. Die Gelenkwellen 5, 6 und damit auch die
Exzenterwellen 14, 15 werden synchronisiert, und zwar
über Synchronwellen 11, die über Riemen 12, 13 mit
den Motorantrieben 9, 10 verbunden sind. Die Motorkonsole
20 ist auf einem Motorständer 4 angeordnet.

Für die Erfindung ist es wesentlich, daß die Exzenterwellen
14, 15 möglichst nahe dem Massenschwerpunkt
16 der Siebmaschine angeordnet sind. Weiterhin
drehen sich die Unwuchten 7 bzw. 8 entgegengesetzt
und es ergibt sich hierbei aufgrund des Kräftediagramms
eine Schwingbewegung des Siebkastens
gemäß der dargestellten Ellipse (Fig. 1 und 5), wobei
die Hauptschwingrichtung 18 mit der Längsachse 19
der Ellipse 21 zusammenfällt. Die Verbindungslinie
durch die Mitte der Exzenterwellen 14, 15 ist die Nullinie
17, wo darüber hinaus die Resultierende der Massenschwingkräfte
am geringsten ist. Der Winkel α zwischen
dieser Linie 17 und der Linie 18 beträgt vorzugsweise
90°, wobei noch zufriedenstellende Ergebnisse im
Bereich bis 60° erzielt werden. In der "Nullstellung" liegen
die Unwuchten 7, 8 auf der Nullinie 17, d.h. der Verbindungslinie
der Achsen der Exzenterwellen 14, 15,
einander gegenüber, d.h. um 180° gegeneinander verdreht,

Dementsprechend ergibt sich dann eine Ellipse 21 bzw.
eine Ellipse 21' bei der größeren Unwucht 7'. Anhand
des Kräfteparallelogramms läßt sich die Resultierende
erzeugen, deren Ortskurve die Ellipse 21 ist. Einige
Punkte der Unwuchtstellungen sind eingezeichnet, und

ist ohne weiteres zu entnehmen, daß der Winkel
zwischen der großen Ellipsenachse 19 und der Nullinie
