KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Schraubensicherung durch ein kegeliges, die Drehbewegung hinderndes Sperrglied, welches in einer kegeligen Ausnehmung an der Unterseite der Schraubenmutter angeordnet und mit Innengewinde versehen ist. Bei einer bekannten Einrichtung dieser Art werden durch das kegelige Sperrglied in der Mutter und im Sperrglied selbst achsial und radial wirkende Druckkräfte erzeugt, welche das Sperrglied auf seiner ganzen Länge fest gegen den Schraubenbolzen drücken. Diese Wirkung wird erfindungsgemäß noch dadurch beträchtlich erhöht, daß das kegelige, mit Innengewinde versehene Sperrglied die Form einer Spiralfeder mit gewindelosen Enden hat.The invention relates to a screw locking device by means of a conical, rotational movement obstructive locking member, which is in a conical recess on the underside of the Screw nut is arranged and provided with an internal thread. With a well-known This type of device is provided by the conical locking member in the nut and in the locking member even axially and radially acting pressure forces generated, which the locking member on its Press firmly against the screw bolt over the entire length. This effect becomes according to the invention still significantly increased by the fact that the conical, internally threaded locking member is in the form of a spiral spring with unthreaded ends.
Die Erfindung ist auf der Zeichnung dargestellt, und zwar ist Fig. 1 eine Ansicht der Sicherung vor dem Zusammenschrauben, Fig. 2 ein vertikaler Schnitt; Fig. 3 ist eine Ansicht des Sperrgliedes und Fig. 4 ein Schnitt durch die Schraubenmutter.The invention is illustrated in the drawing, namely FIG. 1 is a view of FIG Securing before screwing together, Figure 2 is a vertical section; Fig. 3 is a view of the locking member and Fig. 4 is a section through the nut.
Das Sperrglied 1 ist innen zylindrisch und mit Schraubengewinde 2 versehen, außen kegelig gehalten und spiralförmig aufgeschnitten. Seine Enden 3 und 4 sind auf einen etwas weiteren Durchmesser ausgebohrt als der äußere Durchmesser des Bolzens beträgt.The locking member 1 is cylindrical on the inside and provided with a screw thread 2 and is conical on the outside held and cut open in a spiral. Its ends 3 and 4 are on a something Drilled out wider diameter than the outer diameter of the bolt.
Der obere kegelige Teil des Sperrgliedes tritt in eine entsprechend kegelige Ausnehmung 6 der Schraubenmutter 7 ein.The upper conical part of the locking element enters a correspondingly conical recess 6 the nut 7.
Wenn die Teile sich in der Sicherungslage befinden, stemmen die Enden 8 und 9 des Sperrgliedes 1 sich gegen den Boden 10 der Mutterausnehmung 6 und gegen die Auflage 11, hierbei nähern die äußeren Spiralwindungen sich einander, wodurch auch die kegeligen Oberflächen von Mutter und Sperrglied in Berührung kommen, die Schraubenwindungen des mittleren Teiles 2 des Sperrgliedes gegen diejenigen des Bolzens gepreßt werden und außerdem achsial wirkende Druckkräfte entstehen.When the parts are in the secured position, pry ends 8 and 9 of the Locking member 1 against the bottom 10 of the nut recess 6 and against the support 11, here the outer spiral windings approach each other, which also causes the conical ones Surfaces of the nut and locking member come into contact, the screw turns of the middle part 2 of the locking member are pressed against those of the bolt and also axially acting compressive forces arise.
