Description

Gedämpfte Schraubenfeder Die Erfindung betrifft eine gedämpfte Schraubenfeder zur Lagerung von Maschinen u. dgl., bei der koaxial zur Feder ein elastischer Körper angeordnet ist, der die Federwindungen berührt und beim Einfedern zwischen die Windungen gedrückt wird.Damped coil spring The invention relates to a damped coil spring For mounting machines and the like, in which an elastic body is coaxial with the spring is arranged, which touches the spring coils and during compression between the coils is pressed.

Bei derartig federnd gelagerten Maschinen treten infolge Wirkung der in der Maschine frei werdenden Kräfte Bewegungen auf, die häufig unzulässig groß sind, und es besteht die Notwendigkeit, diese Bewegungen auf das zulässige Maß zu verringern.In such resilient machines occur as a result of the effect of Forces released in the machine cause movements that are often inadmissibly large are, and there is a need to keep these movements to the permitted extent to decrease.

Hierfür ist die Flüssigkeitsdämpfung (Viskositätsdämpfung) bekannt. Ferner sind Federn bekannt, die mit einem anderen elastischen Material in Berührung stehen, das, je nach Größe der Bewegungen, durch Reibung oder Materialverformung dämpfend wirkt oder bei großen Bewegungen einzelne Windungen der Feder blockiert.Liquid damping (viscosity damping) is known for this. Furthermore, springs are known which come into contact with another elastic material stand, depending on the size of the movements, by friction or material deformation has a damping effect or blocks individual turns of the spring in the event of large movements.

Da in den meisten Fällen die Unwuchten, die die Ursache der Bewegungen sind, ihrer Größe nach nicht bekannt sind und diese sich auch im Betriebe ändern können, erweist es sich als notwendig, die Dämpfung möglichst während des Betriebes ändern .zu können.Because in most cases the imbalances that are the cause of the movements are not known according to their size and these also change in the company it turns out to be necessary to reduce the damping during operation if possible to be able to change.

Nach der Erfindung wird diese Aufgabe dadurch gelöst, daß die Vorspannung des elastischen Körpers einstellbar ist. Dadurch kann sie jederzeit den gegebenen Erfordernissen angepaßt werden.According to the invention, this object is achieved in that the bias of the elastic body is adjustable. As a result, she can always take the given Needs to be adapted.

Der elastische Körper kann in an sich bekannter Weise im Inneren der Federkörper angeordnet und durch eine Schraube zusammendrückbar sein. Die Schraube ist dabei zweckmäßig die Halterungsschraube des oberen Federtellers.The elastic body can in a manner known per se inside the Spring body arranged and be compressible by a screw. The screw the retaining screw of the upper spring plate is useful.

Ferner empfiehlt es sich, den elastischen Körper in ebenfalls an sich bekannter Weise als geschlitzte Hülse auszubilden, die auf einem im unteren Federteller angeordneten konischen Dorn sitzt.It is also advisable to use the elastic body in itself known way to form as a slotted sleeve on a lower spring plate arranged conical mandrel sits.

In der Zeichnung ist der Gegenstand der Erfindung dargestellt. Es zeigt Fig.1 einen Längsschnitt durch die an einen Maschinenfuß angebaute Schraubenfeder, Fig.2 einen Querschnitt durch den elastischen Körper.In the drawing, the subject matter of the invention is shown. It Fig. 1 shows a longitudinal section through the helical spring attached to a machine base, 2 shows a cross section through the elastic body.

Die Schraubenfeder a sitzt in einer mit der Maschine verbundenen Glocke b und stützt sich auf dem mit dem Fundament verbundenen Fußteil e ab.The coil spring a sits in a bell connected to the machine b and is supported on the foot part e, which is connected to the foundation.

Durch eine Schraube d, die gleichzeitig als Befestigungsschraube für die Maschine dient, kann über eine Druckplatte e ein elastischer Körper f, der zweckmäßig aus Kunststoff oder Gummi besteht, über einen konischen Dorn g geschoben werden.By a screw d, which doubles as a fastening screw for the machine is used, an elastic body f, which is appropriate via a pressure plate e made of plastic or rubber, can be pushed over a conical mandrel g.

Der Körper f ist mit einem Schlitz versehen. Dadurch wird er beim überschieben auf den konischen Dorn aufgespreizt und legt sich innen an die Schraubenfeder.The body f is provided with a slot. This makes him at the slide it over the conical mandrel and lay down on the inside of the helical spring.

Bei geringem Druck wird dadurch eine Reibung erzeugt, die den störenden Bewegungen entgegenwirkt. Wird der Druck verstärkt, dann wird der Körper von den Federgängen mitgenommen und wirkt durch Materialdämpfung ebenfalls bewegungshemmend. Bei noch stärkerem Anziehen der Schraube kann der Druck auf die Federwindungen so verstärkt werden, daß diese im Bereich, in dem der Körper anliegt, blockiert werden. Auf diese Weise wird die Anzahl der federnden Windungen verringert, und die Feder wird härter, was weiterhin zur gewünschten Bewegungsbegrenzung beiträgt.If the pressure is low, friction is generated which reduces the disturbance Counteracts movements. If the pressure is increased, then the body is relieved of the The spring action is carried along and also has a movement-inhibiting effect due to the material damping. If the screw is tightened even more, the pressure on the spring coils can be so be strengthened so that they are blocked in the area where the body rests. In this way, the number of resilient coils is reduced, and the spring becomes harder, which further contributes to the desired limitation of movement.

An Stelle der geschlitzten Hülse, wie in der Zeichnung angedeutet, können auch alle Körper dienen, die durch Druck ihren Durchmesser vergrößern, so z. B. auch kugelförmige oder konische Körper.Instead of the slotted sleeve, as indicated in the drawing, can also serve all bodies that enlarge their diameter through pressure, so z. B. also spherical or conical bodies.
