Abstract
Description
Die Erfindung betrifft eine kraftschlüssige Sicherung gegen selb ständiges Lösen von Gewindeverbindungen, die durch Klemmung er zeugt wird.The invention relates to a positive locking against the same constant loosening of threaded connections by clamping it is fathered.
Um Gewindeverbindungen gegen Lösen abzusichern, gibt es vielfäl tige Möglichkeiten. Ihre Nachteile u. a.: Abnutzung, einmaliger Ge brauch, Beschädigung der Gewinde oder der Werkstückoberflächen und schlechte Lösbarkeit.There are many ways to secure threaded connections against loosening opportunities. Your disadvantages u. a .: Wear, one-off Ge need, damage to the threads or the workpiece surfaces and poor solubility.
Um diese Nachteile auszuschließen, wurde eine kraftschlüssige, klem mende und leicht lösbare Sicherung entwickelt. Dabei wird eine Ge windemutter Fig. 1, Teil 11, vom Innengewinde her so eingeschnitten, daß eine federnde Zunge entsteht, die an ihrer Innenseite das Ge winde beibehält. Von einer der Schlüsselflächen bzw. dem äußersten Umfang her wirkt radial durch eine kleinere Gewindebohrung eine Druckschraube, Fig. 1, Teil 12, die auf das lose Ende der Zunge drückt. Diese drückt wiederum ihr Innengewinde in das Bolzengewin de. Durch den Andruck und die einkeilende Wirkung in die gegensei tigen Gewindeflanken entsteht eine äußerst feste und materialschon ende Verbindung zwischen den Maschinenelementen, Fig. 1, Teile 10 und 11. Daß diese Sicherung nicht nur an reinen Verschraubungen, sondern auch an Maschinenteilen angewendet werden kann, zeigt Fig. 2 eine verstellbare Keilriemenscheibe. Teil 21 ist die Welle mit fester Scheibe. Teil 22 ist der verstellbare Scheibenteller mit der federnden Zunge und Teil 12 die Druckschraube.To eliminate these disadvantages, a force-locking, clamping and easily releasable fuse was developed. Here, a Ge thread nut Fig. 1, part 11 , is cut from the internal thread so that a resilient tongue is created which retains the thread on its inside. From one of the key surfaces or the outermost circumference, a pressure screw, FIG. 1, part 12 acts radially through a smaller threaded bore, which presses on the loose end of the tongue. This in turn presses its internal thread into the bolt thread. The pressure and the wedging effect in the opposing thread flanks creates an extremely strong and material-saving connection between the machine elements, Fig. 1, parts 10 and 11th That this assurance can be applied not only to pure fittings, but also on machine parts, Fig. 2 shows an adjustable V-belt pulley. Part 21 is the shaft with a fixed disc. Part 22 is the adjustable disc plate with the resilient tongue and part 12 is the pressure screw.
Fig. 3 zeigt ein Druckstück. Es kann innerhalb der Schlitzung un ter gebracht werden und minimiert, auch bei hohen Gewindepressungen, etwaige Materialverformungen. Eine Anwendung zeigt Fig. 4. Es ist ein Doppelexzenter. Er ermöglicht nicht nur eine exzentrische Ein stellung, sondern erlaubt auch eine Phasenverschiebung zwischen Welle und Außenexzenter. Fig. 5 stellt ein Maschinenelement dar, dessen Innenteil Teil 53 (Welle) mit dem Innenring aus Isolier- Material Teil 51 mit der kraftschlüssig klemmenden Sicherung ver bunden ist, um eine elektrische Leitfähigkeit zu unterbinden. Der Innenring ist formschlüssig mit Teil 52 verbunden. Fig. 3 shows a pressure piece. It can be accommodated within the slot and minimized, even with high thread pressures, any material deformation. An application is shown in Fig. 4. It is a double eccentric. It not only enables an eccentric adjustment, but also allows a phase shift between the shaft and the external eccentric. Fig. 5 shows a machine element, the inner part 53 (shaft) with the inner ring made of insulating material part 51 with the non-positive locking fuse is connected to prevent electrical conductivity. The inner ring is positively connected to part 52 .
Zu bemerken wäre noch, daß durch die neuen Techniken (Wasserstrahl- und Laserbrennschneiden) die oben genannte Erfindung auch an Klein teilen angewendet werden kann. It should also be noted that the new techniques (water jet and laser flame cutting) the above-mentioned invention also on Klein sharing can be applied.
