Abstract
Die Erfindung schlägt eine Anordnung zur Reduzierung der installierten Antriebsleitung bei Unwuchterregern mit kreisförmiger Schwingbewegung vor, bei der der Start der Hauptantriebsmaschine des Unwuchterregers aus der stabilen Gleichgewichtslage der resultierenden aller Unwuchten, welche sich bei freiem Pendeln derselben einstellen würde, aus einer um 180 ° versetzten Lage heraus erfolgt.The invention proposes an arrangement for reducing the installed drive line in the case of unbalance exciters with a circular oscillating movement, in which the start of the main drive machine of the unbalance exciter from the stable equilibrium position of the resulting imbalances, which would arise if they were to swing freely, from a position offset by 180 ° done out.
Description
stellt Die Arbeitsmaschine wird durch eine Hauptantriebswelle 2 von einer Hauptantriebsvorrichtung 3 angetrieben. Zusätzlich zu der Hauptantriebsvorrichtung ist eine Hilfsantriebsvorrichtung 4 vorgesehen, die beispielsweise über einen Riementrieb S auf die Hauptan- s triebswelle 2 wirkt und der lediglich die Aufgabe hat, den Schwerpunkt der Unwuchtmasse von 0° in Ruhelage in die 180° Stellung (bezüglich der Drehachse) zu verbringen, sich dann ausschaltet, wobei gleichzeitig dann die Hauptantriebsvorrichtung 3 eingeschaltet wird, die Ronmehr für den Betrieb der Arbeitsmaschine Sorge trägtThe working machine is provided by a main drive shaft 2 driven by a main drive device 3. In addition to the main propulsion device an auxiliary drive device 4 is provided, for example acts on the main drive shaft 2 via a belt drive S and which only has the task of the center of gravity of the unbalanced mass from 0 ° in the rest position to the 180 ° position (with respect to the axis of rotation) spend, then turns off, taking at the same time then the main drive device 3 is switched on, the Ron more for the operation of the working machine Cares
Bei einer solchen Einrichtung ist es beispielsweise möglich, die bisher üblicherweise installierte Leistung von 22 kw für die Hauptantriebsvorrichtung auf 11 kw zu reduzieren, während die Hilfsantriebsvorrichtung nur eine Leistung von 03 kw aufweisen muß, um die gewünschte Ausgangsstellung zu erreichen, in der dann die Hauptantriebsvorrichtung tätig wird. Mit einer solchen Anordnung wird nicht nur ein wesentlich besserer Wirkungsgrad der Hauptantriebsvorrichtung erreicht, sondern die bisher aufzuwendenden hohen Kosten für eine überdimensionierte Antriebsmaschine werden vermieden. With such a device, it is possible, for example, to use the previously installed power from 22 kw for the main propulsion device to 11 kw to reduce, while the auxiliary drive device only needs to have a power of 03 kw to the To achieve the desired starting position, in which the main drive device is then active. With such a Arrangement not only achieves a much better efficiency of the main drive device, rather, the high costs previously incurred for an oversized drive machine are avoided.
