Description
- Schraubensicherung- screw locking
Gegenstand der "Erfindung ist eine Schraubensicherung, die ein Anziehen und auch'
ein Nachziehen der Mutter, aber kein Lösen der Mutter mehr gestattet. Das kennzeichnende
Merkmal der Erfindung besteht darin, daß in dem Sechskantteil der Mutter eine mit
Gewinde versehene Muffe drehbar angeordnet ist, die mit dem Sechskantteil durch einen
Freilauf in Verbindung steht. Der Freilauf ίο ist derart angeordnet, daß. beim Anziehen
der Mutter die Muffe von dem Sechskantteil mitgenommen wird, daß aber bei einem Versuche,
die Mutter zu lösen, der Sechskantteil sich frei um die Mutter dreht.
Ein weiteres kennzeichnendes Merkmal der Erfindung besteht darin, daß die Gewindemuffe
an ihrem oberen Ende einen Flansch aufweist, der in dem Sechskantteil versenkt liegt, so daß beim Niederschrauben der Gewindemuffe
der Flansch von oben auf den Sechskantteil drückt und dadurch den Sechskantteil beim Anziehen der Mutter mit feststellt.
The subject of the "invention is a screw locking device which allows tightening and retightening of the nut, but no loosening of the nut. The characteristic feature of the invention is that a threaded sleeve is rotatably arranged in the hexagonal part of the nut, which is connected to the hexagonal part by a freewheel. The freewheel ίο is arranged in such a way that when the nut is tightened, the socket is carried along by the hexagonal part, but that when an attempt is made to loosen the nut, the hexagonal part is free around the nut turns.
Another characteristic feature of the invention is that the threaded sleeve has a flange at its upper end which is sunk in the hexagonal part, so that when the threaded sleeve is screwed down, the flange presses on the hexagonal part from above and thereby the hexagonal part with the tightening of the nut notices.
Die Zeichnung zeigt die Erfindung in einem Ausführungsbeispiel, und zwar in
Abb. ι in einem Längsschnitt und in
Abb. 2 in einem Schnitt nach der Linie x-x der Abb. 1.The drawing shows the invention in one embodiment, namely in
Fig. Ι in a longitudinal section and in
Fig. 2 in a section along the line xx in Fig. 1.
In dem Sechskantteil 1 ist die mit dem Gewinde versehene Muffe 2 drehbar angeordnet, die die Sperrnasen 3 aufweist, welche sich beim Anziehen der Mutter in die Rasten 4 des Sechskantteiles 1 einlegen, beim Lösen dagegen die Rasten 4 verlassen und in die Aussparungen 5 der Gewindemuffe 2 zurückfedern. Die Gewindemuffe 2 weist an ihrem oberen Ende einen Flansch 6 auf, der in dem Sechskantteil 1 versenkt liegt und sich beim Aufschrauben der Mutter auf den Bolzen 7 gegen eine Schulter 8 des Sechskantteiles legt.In the hexagonal part 1, the threaded sleeve 2 is rotatably arranged, which has the locking lugs 3, which when the nut is tightened into the notches 4 of the hexagon part 1 insert, when loosening, however, leave the notches 4 and into the Spring back the recesses 5 of the threaded socket 2. The threaded sleeve 2 has on her the upper end of a flange 6, which is sunk in the hexagonal part 1 and when screwing the nut onto the bolt 7 against a shoulder 8 of the hexagonal part lays.
Diese Vorrichtung gestattet nur ein An- und ein Nachziehen der Mutter, ein Lösen ist dagegen nicht möglich, da beim Rückwärtsdrehen des .Sechskantes 1 die Muffe 2 nicht mitgenommen wird.This device only allows tightening and retightening of the nut, loosening is on the other hand not possible, because when turning the hexagon 1 backwards, the socket 2 does not is taken.
