Description
Zur Unschädlichmachung kritischer Drehzahlen oder zur Erzielung großer Gleich- i förmigkeit des Ganges von Kölbenmaschinen kann man bekanntlich federnd mit der Maschinenwelle oder mit einer auf der Welle sitzenden Masse verbundene Hilfsmassen anwenden. Die vorliegende Erfindung bezieht sich auf eine besondere Anordnung einer solchen Zusatzmassie, die wesentliche technischeTo render critical speeds harmless or to achieve greater equal i The shape of the gait of piston machines is known to be resilient with the machine shaft or use auxiliary masses connected to a mass sitting on the shaft. The present invention relates to a particular arrangement of such Additional mass, the essential technical
ίο Vorteile bietet. Gemäß der Erfindung wird die Hilfsmasse in dem von einer Maschinenkurbel durchlaufenen Raum angeordnet. Dies hat den Vorteil, daß zur Unterbringung der Vorrichtung keinerlei Raumaufwand zu machen und keinerlei konstruktive. Maßnahmen zu treffen sind, so daß die Vorrichtung auch nachträglich an jeder ausgeführten Maschine angebracht werden kann. Die Anordnung hat aber noch einen anderen sehr wesentlichen Vorzug:ίο offers advantages. According to the invention the auxiliary mass is arranged in the space traversed by a machine crank. this has the advantage that there is no need for space to accommodate the device and no structural requirements whatsoever. measures are to be taken so that the device can also be carried out retrospectively on each Machine can be attached. The arrangement has another very important advantage:
Solche federnde Hilfsmassen wirken nämlich in der Weise, daß sie ' infolge relativer Schwingungen zur Welle ein harmonisches Drehmoment hervorrufen, welches dem die.Such resilient auxiliary masses act in such a way that they 'as a result of relative Vibrations to the shaft cause a harmonic torque, which the.
störenden Wellenverdrehüngen verursachenden harmonischen Moment der Kurbelkräfte entgegenwirkt und es ganz oder zum größten Teil aufhebt. Infolge dieser Wirkungsweise wird die Vorrichtung am richtigsten mögliehst unmittelbar am Angriffspunkt der Kurbelkräfte angeordnet, wie es bei der vorliegenden Anordnung der Fall ist.the harmonic moment of the crank forces causing disruptive shaft rotations counteracts it and completely or for the most part cancels it. As a result of this mode of action the device is most correct as possible directly at the point of application of the crank forces arranged, as is the case with the present arrangement.
Die Anordnung ist in einem Ausführungsbeispiel in der Zeichnung dargestellt, und zwar gibt Fig. ι einen Schnitt durch die Maschinenwelle, Fig. 2 eine Ansicht in Richtung der Wellenachse. Die Zusatzmasse m ist zum Teil neben und vor dem Kurbelschenkel k angeordnet und hat um k und um den Kurbelzapfen ζ bzw. um die Schale des Pleuel-Stangenlagers genügend Spielraum für Schwingungen relativ zur Welle. Die Masse ni ist mit der Feder / verbunden, welche beispielsweise als gerade Drehfeder ausgebildet ist, die in einer Bohrung /; der Welle liegt und an ihrem anderen Ende an der Welle befestigt ist.The arrangement is shown in an exemplary embodiment in the drawing, namely FIG. 1 shows a section through the machine shaft, FIG. 2 shows a view in the direction of the shaft axis. The additional mass m is arranged in part next to and in front of the crank arm k and has enough leeway for vibrations relative to the shaft around k and around the crank pin ζ or around the shell of the connecting rod bearing. The mass ni is connected to the spring /, which is designed, for example, as a straight torsion spring which is inserted in a bore /; the shaft and is attached to the shaft at its other end.
