Description
Die bekannten Schraubensicherungen sind häufig ]licht geeignet, das ungewollte Lösen von Schrauben bzrv. deren Nfuttern zu verhindern. Als Beispiel unter vielen sei auf die Gestängeverschraubungen bei Schüttelrutschen im Bergbaubetriebe hingewiesen, bei denen immer wieder sich Muttern oder Schrauben lösen,, trotz Anwendung bester Sicherungen. Außer starren Sicherungen, wie Gegenmuttern, sind auch solche bekannt, welche elastische Mittel, z. B. Federringe, als Unterlegscheibe vorsehen, die auch als Torsionsfedern ausgebildet sein können.The known screw locks are often] light suitable that unintentional loosening of screws or to prevent their feed. As an an example among many is the bolted linkage on shaking chutes in mining operations pointed out, in which nuts or screws loosen again and again, despite use best fuses. In addition to rigid locks such as lock nuts, there are also lock nuts known which elastic means, e.g. B. Provide spring washers as a washer, which can also be designed as torsion springs.
Die unter schwersten Bedingungen bei Schüttelrutschen erprobte Sicherung gegen Lösen von Schrauben oder Muttern nach der vorliegenden l#.rficidurtg ist dadurch gekennzeichnet, <laß sie aus einer Hülse aus starkwandigem elastischem Stoff, insbesondere Gummi, besteht, d>ie auf einen Zapfen hinter der zu sichernden Mutter aufgeschraubt oder aufgeklemtnt ist.The safety device that has been tried and tested under the most difficult conditions on jolting slides against loosening of screws or nuts according to the present l # .rficidurtg is thereby marked, <let them out of a sleeve made of thick-walled elastic material, in particular rubber, there is, d> ie on a pin behind the nut to be secured is screwed on or clipped on.
Eine solche Hülse löst sich nie infolge eines axialen oder Torsionsdruckes einer Mutter, gegen welche sie sich abstützt. Ein Stauchen der Hülse bei sich lösender Mutter löst solch große elastische Gegendrücke aus, (lad die Mutter, sicher wieder bei den sich folgenden Erschütterungen in ihre alte Lage zurückgeführt wird.Such a sleeve will never come loose as a result of axial or torsional pressure a mother against whom she supports herself. A compression of the sleeve when it comes loose Mother triggers such great elastic counter-pressures, (load mother, safe again is returned to its old position in the subsequent tremors.
Auf der Zeichnung ist der Erfindungsgegenstand in zwei beispielsweisen Ausführungsformen dargestellt.The subject of the invention is shown in two examples in the drawing Embodiments shown.
Abb. t zeigt das Ende einer Stange a reit aufgeschraubter Mutter b. Die Stange a ist um einen Zapfen c verlängert, der steiles, stark auftragendes Gewinde d, z. B. Kordelgewinde, hat. Auf den "Zapfen ist mit großer Spannung eine im Längsschnitt dargestellte Hülse e aus starkwandigem Gutntni aufgeschraubt, die sich gegen die zu sichernde Mutter abstützt.Fig. T shows the end of a rod a with a screwed nut b. The rod a is extended by a pin c, the steep, heavily bulky thread d, z. B. cord thread has. A sleeve e, shown in longitudinal section, made of thick-walled material and supported against the nut to be secured, is screwed onto the "pin" with great tension.
Bei der Ausführungsform nach Abb.2 und 3 dient ein gewindeloser, aber mit Kehlung f versehener Zapfen g als Halter für die Gumrnihülse, die durch eine Kausche h in der Kehlung umgriffen und in diese eingepreßt wird. Auch in Abb. 2 ist die Hülse e im Längsschnitt und in Abb. 3 itn Querschnitt nach Linie .1-l3 der Abb. 2 dargestellt.In the embodiment according to Fig.2 and 3, a threadless, but with groove f provided pin g as a holder for the rubber sleeve, which is through a Thimble h is grasped in the groove and pressed into it. Also in Fig. 2 is the sleeve e in longitudinal section and in Fig. 3 itn cross-section along line .1-l3 of the Fig. 2 shown.
Es dürfte klar sein, daß auch andere Mittel, z. B. Schellen, zum Befestigen der Gummihülsen dienen können, wie überhaupt je nach Art der Maschinenteile oder Bauelemente, bei denen die Schraubensicherung Anwendung finden soll, sich diese entsprechend gestalten muß.It should be clear that other means, e.g. B. clamps for fastening the rubber sleeves can serve as at all depending on the type of machine parts or Components in which the screw locking is to be used, these must design accordingly.
