Description
Schraubensicherung Die Erfindupg bezieht sich auf solche Schraubensicherungen, bei ,denen in einer Nut der Mutter quer zur Bolzenachse ein Zahnkeil angeordnet ist, der beim Anziehen der Mutter lose an dem Gewinde des Bolzens; vorbeigleitet, bei einer Lösungsbewegung der Mutter sich aber zwischen die Rückwand der Nut und das Bolzengewinde hineinzieht und .so, eine Bewegung zwischen Bolzen und Mutter verhindert. Bei diesen. Sicherungen hat sich der Nachteil gezeigt, daß der Zahnkeil nicht immer einwandfrei in Sperrstellung gezogen wurde, wenn er nicht dauernd in Berührung sowohl mit dem Gewinde als der Rückwand der Nut in der Mutter ,gehalten wird. Gemäß der Erfindung wird der Keil durch eine an der Mutter befestigte Feder in die Sperrstellung gedrückt, derart, daß bei Lösungsversuchen der Mutter das Hineinziehen ,des Keiles in die Klemmstellun,gunterstützt wird.Screw locking The invention relates to such screw locking, in which a toothed wedge is arranged in a groove of the nut transversely to the bolt axis is that when tightening the nut loosely on the thread of the bolt; glides past, with a solution movement of the mother but between the back wall of the groove and the bolt thread pulls in and .so, a movement between the bolt and nut prevented. With these. Fuses have shown the disadvantage that the tooth wedge has not always been properly pulled into the locked position if it is not permanently in Contact with both the thread and the back wall of the groove in the nut will. According to the invention, the wedge is secured by a spring attached to the nut pressed into the locked position, so that when trying to solve the mother pulling it in , the wedge in the clamping position is supported.
Die Erfindung ist in der Zeichnung dargestellt.The invention is shown in the drawing.
Abb. i zeigt die Sicherung in Ansicht, Ab-b. 2 in Aufsicht, Abb. 3 zeigt die Feder in Aufsicht und Ansicht und Abb. q. den Zahnkeil.Fig. I shows the fuse in view, Ab-b. 2 in top view, Fig. 3 shows the spring in plan and elevation and Fig. q. the tooth wedge.
In einer Ringnut der Mutter ist eine Federe so angeordnet, daß sie mit ihrem einen Ende den in einer Nut der Mutter b angeordneten ZahnkeiLd zwischen die Rückwand dieser Nut und das Gewinde des Bolzens u drückt.In an annular groove of the nut a spring is arranged so that it with one end of the toothed key arranged in a groove of the nut b between the back wall of this groove and the thread of the bolt press u.
Hierdurch wird !erreicht, daß der Keil dauernd in inniger Berührung mit den. beiden zu sperrenden Teilen ,gehalten und ein Ver-,sagen der. Sicherung mit Sicherheit vermieden wird.This ensures that the wedge is constantly in intimate contact with the. both parts to be blocked, held and a failure, say the. Fuse will certainly be avoided.
