Description

Verschiedene Mittel zum Massenausgleich von Kolbenkraftmaschinen mit hin und her gehenden Massen durch zusätzlich angebrachte schwingende oder rotierende Massen sind bekannt.Various means for balancing the masses of reciprocating engines with back and forth moving masses by additionally attached oscillating or rotating masses are known.

Die Praxis bedingt, daß Massenausgleichsvorrichtungen erst eingebaut werden, wenn sich Störungen durch Übertragung von Erschütterungen zeigen. Denn diese Störungen sind abhängig von der Beschaffenheit des Baugrundes und Zufälligkeiten, die vorher schwer oder gar nicht zu ermitteln sind. Daher ordnet man diese Ausgleichsvorrichtungen in besonderen Ausgleichsapparaten an, die gewöhnlich aus zwei gegenläufig rotierenden Gewichten, deren senkrechte Wellen in einem gemeinschaftlichen Gehäuse angeordnet sind, bestehen. Da die freien Massenkräfte am Rahmen angreifen, hat man bisher auch den Ausgleichsapparat mit dem Rahmen verbunden.Practice requires that mass balancing devices are only installed when there are disturbances due to the transmission of vibrations. Because these disturbances are dependent on the nature of the subsoil and randomnesses that occurred beforehand difficult or impossible to determine. Therefore, one arranges these balancing devices in special compensating devices, which usually consist of two counter-rotating Weights, the vertical shafts of which are arranged in a common housing are exist. Since the free inertial forces act on the frame, you have previously also had the compensation apparatus with the frame tied together.

Besonders bei Maschinen mit Bajonettrahmen bietet die Verbindung von Maschine und Ausgleichsapparat konstruktiv große Schwierigkeiten, häufig ist sie sogar unmöglich. Diese Schwierigkeit wird durdh die vorliegende Erfindung beseitigt.The connection between machine and Compensating apparatus constructively has great difficulties, often it is even impossible. This difficulty is eliminated by the present invention.

Der Ausgleichsapparat α wird auf der der Kurbelwelle abgewandten Seite der Maschine aufgestellt und nicht mit dem Rahmen, sondern mit dem hinteren Zylinderflansch b verschraubt. Die Schrauben c erhalten dadurch keine zusätzliche Beanspruchung, der sie nicht gewachsen wären; denn die Eigenart der Kräftewirkung innerhalb der Maschine bedingt, daß die Schrauben, die den Zylinderdeckel halten, durch die im Ausgleichsapparat erzeugten Kräfte entlastet werden, wenn sie durch den Dampfdruck beansprucht werden und nur durch ;den Massenausgleich belastet werden, wenn der Dampfdruck sie nicht beansprucht.The compensation apparatus α is set up on the side of the machine facing away from the crankshaft and is screwed not to the frame but to the rear cylinder flange b. As a result, the screws c do not receive any additional stress which they would not be able to cope with; Because the peculiarity of the force effect within the machine means that the screws that hold the cylinder cover are relieved by the forces generated in the equalizing apparatus when they are stressed by the steam pressure and only by the mass balance when the steam pressure does not stress them .

Auf diese Weise ist es möglich, die Kräfte des Ausgleichsapparates mit ' denselben Schrauben aufzunehmen, die den Zylinderdeckel halten.In this way it is possible to use the same forces in the balancing apparatus Include screws that hold the cylinder cover.
