Description

Die Erfindung betrifft eine Schraubenmuttersicherung, bei welcher die Sicherung durch eine auf den Bolzen unterhalb der Mutter gesteckte Evolutenfeder erreicht wird. Von den bekannten Sicherungen dieser Art unterscheidet sie sich dadurch, daß der Querschnitt der äußeren Windung der Evolutenfeder eine größere Höhe hat als der Querschnitt der inneren Windungen. Damit wirdThe invention relates to a screw nut lock, in which the lock is achieved by an evolute spring placed on the bolt below the nut. It differs from the known fuses of this type in that the cross-section of the outer coil of the evolute spring has a greater height than the cross-section of the inner coils. So that will

ίο eine gleichmäßige Federwirkung erzielt, und as werden Federüberspannungen vermieden, weil die inneren Federwindungen freies Spiel haben.ίο a uniform spring effect is achieved, and As spring overstresses are avoided, because the inner spring coils have free play to have.

Die Feder verjüngt sich bai der gewöhnliehen Ausführung am Anfang und am Ende, ist also ungleich stark. Die Erfindung schafft demgegenüber gleiche Dicke in radialer Richtung dadurch, daß die Federwindungen in dieser Richtung mit einer Kröpfung derart versehen sind, daß die Feder innen wie außen zylindrische Form erhält.The spring tapers in the usual way at the beginning and at the end, is therefore unequally strong. In contrast, the invention creates the same thickness in the radial direction in that the spring windings are provided with a crank in this direction in such a way that the spring inside and outside cylindrical shape.

Auf der Zeichnung ist ein Ausführungsbeispiel das Erfindungsgegenstandes dargestellt. Es zeigen:An exemplary embodiment of the subject matter of the invention is shown in the drawing. Show it:

Abb. ι die Sicherung mit den angrenzenden Teilen in gebrauchsfertigem Zustand in Ansicht, Fig. Ι the fuse with the adjacent parts in a ready-to-use state in view,

Abb. 2 einen Querschnitt durch die Sicherung selbst,Fig. 2 shows a cross section through the fuse itself,

Abb. 3 einen Grundriß zu Abb. 1 mit der Feder in der einen Ausführungsform,Fig. 3 is a plan of Fig. 1 with the Spring in one embodiment,

Abb. 4 einen Grundriß mit der Feder in der anderen Ausführungsform.Fig. 4 is a plan view with the spring in the other embodiment.

α ist die Evolutenfeder, die auf den Schraubenbolzen unterhalb der Mutter c aufgesteckt wird, d, e und f sind von innen her aufeinanderfolgende Federwindungen. Gemäß der Erfindung hat die äußere Windung f eine größere Höhe als die Windungen d und e. α is the evolute spring, which is attached to the screw bolt below the nut c , d, e and f are successive spring coils from the inside. According to the invention, the outer turn f has a greater height than the turns d and e.

Nach Abb. 3 verjüngt sich entsprechend der bisher üblichen Ausführungsform die Feder am Anfang und am Ende. Wie Abb. 4 zeigt, ist dies gemäß der Erfindung dadurch vermieden, daß in radialer Richtung jede Windung der Feder eine Kröpfung besitzt. Diese Kröpfungen legen sich so aneinander, daß die Federwindungen an sich ringsum gleiche Stärke besitzen.According to Fig. 3 tapers according to the previously usual embodiment Feather at the beginning and at the end. As Fig. 4 shows, this is in accordance with the invention avoided that each turn of the spring has a crank in the radial direction. These cranks lie against each other in such a way that the spring coils are all around have the same strength.
