Description

Elastische Lagerung für schnellrotierende Wellen, insbesondere Zentrifugenwellen Gemäß der Hauptpatentanmeldung erfolgt die elastische Lagerung von schnellrotierenden Wellen, insbesondere Zentrifugenwellen, mit Hilfe eines die Welle des rotierenden Teils schlauchförmig umgebenden Lagerelementes, dessen aus eigengedämpftem, elastischem Material bestehender elastischer Teil Aussparungen und an seinen Enden je einen festhaftenden Metallring aufweist. Die Aussparungen können nach der Hauptpatentanmeldung den elastischen Teil des Lagerelementes in seiner ganzen Stärke durchsetzen, so daß offene Fenster entstehen, es kann aber auch über den Aussparungen eine dünne, die Federungseigenschaften praktisch nicht beeinflussende Haut elastischen Materials stehen bleiben.Elastic mounting for fast rotating shafts, especially centrifuge shafts According to the main patent application, the elastic storage of rapidly rotating Shafts, especially centrifuge shafts, with the help of the shaft of the rotating Partly tubular surrounding bearing element, its from self-damped, elastic Material of existing elastic part recesses and one at each of its ends Has firmly adhering metal ring. The recesses can after the main patent application enforce the elastic part of the bearing element in all its strength, so that open windows arise, but there can also be a thin, the elastic material skin, which has practically no effect on the suspension properties stop.

Wie sich gezeigt hat, ist es zweckmäßig, den zwischen den Aussparungen verbleibenden, die Federung übernehmenden Teilen eine bestimmte Form zu geben. Der Erfindung liegt die Aufgabe zugrunde, das Lagerelement nach der Hauptpatentanmeldung in dieser Richtung zu verbessern. Die Verbesserung besteht darin, daß das zwischen zwei Aussparungen im elastischen Teil des Lagerelementes verbleibende Material einen annähernd kreisförmigen Querschnitt aufweist.As has been shown, it is useful between the recesses to give the remaining parts that take over the suspension a certain shape. Of the The invention is based on the object, the bearing element according to the main patent application to improve in this direction. The improvement is that the between two recesses in the elastic part of the bearing element remaining material one has approximately circular cross-section.

Versuche haben bestätigt, daß eine solche Ausbildung günstige Schwingungseigenschaften, insbesondere in der Querrichtung hat. Es wird damit ein in allen Querrichtungen gleiches Federfeld für die Wellenaufhängung erreicht.Tests have confirmed that such a design has favorable vibration properties, especially in the transverse direction. It becomes one in all transverse directions the same spring field for the shaft suspension is achieved.

Weitere Merkmale der Erfindung und die sich daraus ergebenden Vorteile können der nachstehenden Erläuterung des in der Zeichnung dargestellten Ausführungsbeispiels entnommen werden. Als Ausführungsbeispiel ist ein elastisches Lagerelement dargestellt, bei dem die Aussparungen von einer dünnen Haut elastischen Materials überzogen sind.Further features of the invention and the advantages resulting therefrom can the following explanation of the embodiment shown in the drawing can be removed. An elastic bearing element is shown as an exemplary embodiment, in which the recesses are covered by a thin skin of elastic material.

Fig. 1 zeigt einen Längsschnitt und Fig.2 einen Querschnitt durch einen Lagerkörper gemäß der Erfindung.Fig. 1 shows a longitudinal section and Fig. 2 a cross section through a bearing body according to the invention.

Das Lagerelement besteht aus dem schlauchförmigen elastischen Teil 1 und den an seinen beiden Enden festhaftend angeordneten starren Teilen 2 und 3. Die starren Teile sind als Metallringe ausgebildet und dienen der Befestigung einerseits am rotierenden Teil und andererseits am Maschinengehäuse. Der elastische Teil l des Lagerelementes zeigt fünf die Federung übernehmende Teile 4, zwischen denen die Aussparungen 5 vorgesehen sind. Diese sind, um eine Dichtheit des Lagerkörpers zu erzielen, von einer dünnen Gummihaut 6 überdeckt. Die der Federung dienenden Teile 4 weisen einen runden Querschnitt auf. Sie sind etwa säulenartig ausgebildet, weil der runde oder ein ihm angenäherter vieleckiger Querschnitt gute Schwingungseigenschaften aufweist, da er wechselfester ist als eine aus Ringsegmenten bestehende Lagerung.The bearing element consists of the tubular elastic part 1 and the rigid parts 2 and 3 which are firmly adhered at both ends. The rigid parts are designed as metal rings and are used for fastening on the one hand on the rotating part and on the other hand on the machine housing. The elastic part l of the bearing element shows five parts 4 taking over the suspension, between which the recesses 5 are provided. These are to ensure a tightness of the bearing body to achieve, covered by a thin rubber skin 6. The ones used for suspension Parts 4 have a round cross-section. They are roughly columnar, because the round or a polygonal cross-section approximated to it has good vibration properties has, since it is more changeable than a bearing consisting of ring segments.
