Description
DEUTSCHESGERMAN
Bisher wird zum Schutz für Verschraubungen gegen mechanischen Verschleiß, Korrosionen, Schmutz od. dgl. vorgeschlagen, die Mutter oder sonstige Maschinenteile mit einer luftdicht aufsitzenden elastischen Haube aus elastischen Werkstoffen mit hohen mechanischen Festigkeitseigenschaften zu versehen. Als solche Werkstoffe kommen vorzugsweise Kunststoffe zur Anwendung, die nach dem Prinzip der Polyaddition aufgebaut sind, beispielsweise Kondensate aus Isocyanaten mit Polyestern od. dgl. Die praktischen Erfahrungen haben gezeigt, daß der Haubenschutz aus solchen Werkstoffen auch gegen mechanische Beanspruchungen insbesondere auf Abrieb, wirksame Erfolge hat. Nach Patent 1 000 641 wird vorgeschlagen, daß die feuchtigkeitsdicht aufsitzenden Mittel mit einer die Schraube oder das Gewinde abdichtenden Haube mit der Schraubenmutter aus einem Stück Kunststoff bestehen.So far, it has been used to protect screw connections against mechanical wear, corrosion, and dirt Od. Like. Proposed, the mother or other machine parts with an airtight elastic seated To provide hood made of elastic materials with high mechanical strength properties. Such materials are preferably plastics that are based on the principle of polyaddition are built up, for example condensates of isocyanates with polyesters or the like. The practical Experience has shown that the hood protection made of such materials also protects against mechanical Stresses, especially on abrasion, has effective results. According to patent 1 000 641 suggested that the moisture-tight sitting means with a screw or thread sealing The hood with the screw nut is made from a single piece of plastic.
Die Erfindung sieht eine weitere Ausbildung vor, um auf einfachste Weise einen Schutz für Verschraubungen zu verwirklichen. Zu diesem Zweck wird das Neue insbesondere darin gesehen, daß die Mutter von einem beidendig offenen Rohrstück gebildet wird und dieses Rohrstück von einem einendig offenen Hohlkörper ausgefüllt ist, der die Gewindebohrung des Schraubenbolzens besitzt und aus dem elastischen Haubenwerkstoff besteht.The invention provides a further embodiment in order to provide protection for screw connections in the simplest possible way to realize. To this end, the new is seen in particular in the fact that the mother of a pipe section open at both ends is formed and this pipe section is formed by a hollow body open at one end is filled, which has the threaded hole of the screw bolt and from the elastic Hood material consists.
Der Erfindungsgegenstand ist in der Zeichnung in einer beispielsweisen Ausführungsfocm schematisch dargestellt, und zwar zeigtThe subject matter of the invention is shown schematically in the drawing in an exemplary embodiment shown, namely shows
Abb. 1 den Schutz für Verschraubungen im Längsschnitt, Fig. 1 the protection for screw connections in longitudinal section,
Abb. 2 den Gegenstand der Abb. 1 in Draufsicht.
Wie aus der Zeichnung ersichtlich, wird die Mutter von einem metallischen Rohrstück 1 gebildet, das an
seinen beiden Enden offen ist. Das Rohrstück 1 wird durch einen einendig offenen Hohlkörper 2 aus einem
elastischen Haubenwerkstoff ausgefüllt. Das Rohrstück weist auf dem geschlossenen Ende des Hohlkörpers
2 anliegenden Seite einen nach innen eingebördelten Rand 3 auf. Auf seinem Umfang ist das
Rohrstück mit einer Sicke 4 versehen. Der innere elastische Hohlkörper 2 überragt das Rohrstück 1 an
seinem offenen Ende um ein geringes Maß 5. Beim Aufschrauben einer solchen Mutter entsteht ein Einpressen
des elastischen Hohlkörpers 2 in seiner Hülse 1, so daß das Gewinde des Schraubenbolzens 6
fest verspannt ist. Der Schutz gegen Verdrehung der Mutter gegenüber dem Schraubenbolzen 6 wird dadurch
vergrößert, daß der Gewindegang des Schraubenbolzens 6 und derjenige der erfindungsgemäßen
Mutter eine geringfügige Abweichung besitzen.Fig. 2 the subject of Fig. 1 in plan view.
As can be seen from the drawing, the nut is formed by a metallic pipe section 1 which is open at both ends. The pipe section 1 is filled by a hollow body 2, open at one end, made of an elastic hood material. The pipe section has an inwardly crimped edge 3 on the side adjacent to the closed end of the hollow body 2. The pipe section is provided with a bead 4 on its circumference. The inner elastic hollow body 2 projects beyond the pipe section 1 at its open end by a small amount 5. When such a nut is screwed on, the elastic hollow body 2 is pressed into its sleeve 1, so that the thread of the screw bolt 6 is tightly clamped. The protection against rotation of the nut with respect to the screw bolt 6 is increased in that the thread of the screw bolt 6 and that of the nut according to the invention have a slight difference.
