Description
Vorrichtung zum Befestigen von Flugzeugmotoren auf ihrem Fundament unter Verwendung elastischer Puffer Es ist schon vorgeschlagenworden, Flugzeugmotoren mittels Gummipuffer auf dem Motorfundament zu lagern, um die vom Motor herrührenden Erschütterungen vom Fundament und Rumpf fernzuhalten. Von der Verwendung derartiger Puffer hat man bisher Abstand genommen, weil eine einwandfreie und betriebstechnisch durchaus zuverlässige Verbindung zwischen Motor undFundament über solche elastischen Zwischenlager nicht möglich war. So stand zu befürchten, riaß eine derartige Verbindung Formveränderungen unterliegt, die die Sicherheit des Flugzeugs gefährden.Device for fastening aircraft engines on their foundations using elastic buffers, aircraft engines have been proposed to be stored on the engine foundation by means of rubber buffers in order to avoid the Keep the foundation and hull away from vibrations. From the use of such So far, buffers have been refrained from because they are flawless and operationally absolutely reliable connection between the motor and the foundation via such elastic ones Interim storage was not possible. It was to be feared that such a connection would break Is subject to changes in shape that endanger the safety of the aircraft.
Die Erfindung löst dieses Problem in der Weise, daß an Stelle der üblichen Motorbefestigungsbolzen in sich geschlossene Elemente verwendet werden, an denen die Erschütterungsarbeit durch elastische Einlagen aufgezehrt wird.The invention solves this problem in such a way that instead of the common engine mounting bolts self-contained elements are used, where the vibration work is consumed by elastic inserts.
In diesen Elementen wird sowohl durch normale als auch durch in bezug auf die Motorachse tangentiale Erschütterungskräfte hervorgerufene Arbeit aufgezehrt.In these elements is referred to both by normal and by the work caused by tangential vibration forces on the motor axis is consumed.
Eine beispielsweise Ausführung eines solchen Elements ist in Abb. i dargestellt. Der zylindrische Hohlkörper z bildet ein Drehstück mit dem Bolzen 2, mit welchem der Hohlkörper fest mit der Fundament bzw. der Motorseite verbunden wird. In diesem Hohlkörper befindet sich eine elastische Einlage 3, die so bemessen ist, daß ein pilzförmiges Drehteil eingesetzt werden kann. Dieses Drehteil besteht aus einem Flansch 4 mit angedrehtem Schaft 5. Der Flansch wird auf seiner Rückseite durch eine in dem Hohlkörper eingesetzte elastische Einlage 6 abgedeckt. Durch eine überwurfmutter 7 wird der Flansch 4 samt den elastischen, Einlagen an den Hohlkörper i elastisch angepreßt. Der Schaft 5 dient zur festen Verbindung mit dem Motor bzw. dem Motorfundament.An example of such an element is shown in Fig. i shown. The cylindrical hollow body z forms a rotating piece with the bolt 2, with which the hollow body is firmly connected to the foundation or the engine side will. In this hollow body there is an elastic insert 3, which is so dimensioned is that a mushroom-shaped rotating part can be used. This rotating part consists from a flange 4 with turned shaft 5. The flange is on its back covered by an elastic insert 6 inserted in the hollow body. By a Union nut 7 is the flange 4 together with the elastic, inserts on the hollow body i pressed elastically. The shaft 5 is used for a fixed connection to the motor or the engine foundation.
Eine andere Ausführung ist in Abb. 2 dargestellt. Sie besteht darin, daß sowohl der motorseitige Bolzen 2 als auch der fundamentseitige Bolzen 5 je einen Flansch 4 besitzen. Zwischen diesen beiden Flanschen befindet sich eine elastische Einlage B. Die Rückseiten der Flanschen werden durch elastische Einlagen 6 abgedeckt. Die so entstehenden Dämpfungselemente werden durch zwei ineinander verschraubte Hohlkörper und 7 zusammengepreßt.Another design is shown in Fig. 2. It consists in that both the engine-side bolt 2 and the foundation-side bolt 5 each have one Have flange 4. Between these two flanges there is an elastic one Insert B. The back of the flanges are covered by elastic inserts 6. The resulting damping elements are screwed into each other by two Hollow body and 7 pressed together.
