Description
Den Gegenstand der Erfindung bildet eine Schraubenmuttersicherung. Das Wesen der Erfindung besteht darin, daß die Sicherung durch eine Unterlegscheibe geschieht, die mit aufgeibörteltem Rand versehen und mit einer Stahlscheibe verbunden ist, die in ihrer Bohrung zwei sich diametral gegenüberliegende Zapfen besitzt.The subject of the invention is a nut lock. The essence of Invention is that the backup is done by a washer with provided with a flared edge and with a Steel disc is connected, the two diametrically opposed in their bore Possesses cones.
Auf der Zeichnung ist ein Ausfübrungsbeispiel der Erfindung dargestellt, und zwar zeigt:In the drawing, an exemplary embodiment of the invention is shown, namely shows:

Es bezeichnet α die Unterlegscheibe aus Eisen mit aufgebörteltem glatten Rand b. It designated α, the washer made of iron with b aufgebörteltem smooth edge.
Die Scheibe« ist mit einer harten Stahl-■scheibe c verbunden, die in ihrer Bohrung zwei sich diametral gegenüberliegende Zapfen d besitzt. The disk is connected to a hard steel disk c which has two diametrically opposed pins d in its bore.
Die Wirkungsweise ist folgende: Die Unterlegscheibe a, deren Durchmesser gerade nur so groß ist, daß die Mutter g sich darin drehen läßt, wird mit den zwei Zapfen d, die passend zu den Gewindegängen gestaltet sind, auf den Schraubenbolzen f aufgeschraubt. Dabei sitzt die Unterlegscheibe a, c der Steigung des Gewindes entsprechend schräg auf dem Schraubenbolzen/ (Abb. 2). Beim Festziehen der Mutter g wird die schrägstehende Unterlegscheibe a, c gerade gedrückt (Abb. 4). Dabei schneiden sich die Zapfen d in den darunterliegenden Gewinidegang ein und verhindern das Drehen der Unterlegscheibe auf dem ■Schraubenbolzen /. Um nun auch die Mutter g vor dem ungewollten Losdrehen zu schützen, wind der Rand h der Unterlegscheibe α an die Seitenwände der Mutter g angerichtet (Abb. 3 und 4).The mode of operation is as follows: The washer a, the diameter of which is just so large that the nut g can be turned in it, is screwed onto the screw bolt f with the two pins d, which are designed to match the threads. The washer a, c sits at an angle on the screw bolt / (Fig. 2), depending on the pitch of the thread. When tightening the nut g , the inclined washer a, c is pressed straight (Fig. 4). The pins d cut into the thread below and prevent the washer from turning on the ■ screw bolt /. In order to protect the nut g from unintentional loosening, the edge h of the washer α is arranged against the side walls of the nut g (Figs. 3 and 4).
Die Schraubensicherung zeichnet sich durchThe screw lock is characterized by
ihre einfache Bauart aus. Der Schraubenbolzen wird nicht geschwächt. Die Sicherung kann auch da angebracht werden, wo durch Rippen, Wandungen oder sonstige Hindernisse wenig Platz für das Drehen der Mutter gegeben ist. Der glatte Rand der Unterlegscheibe kann in jeder Stellung der Mutter angerichtet werden, was bei eingeschnittenem· oder mit Vor Sprüngen versehenem Rand nicht ίο der Fall ist. Auch kann der glatte Rand zurückgebogen werden, wenn ein Nachziehen oder Lösen der Mutter nötig ist.their simple design. The screw bolt is not weakened. The backup can also be attached where there are ribs, walls or other obstacles there is little space for turning the nut. The smooth edge of the washer can be arranged in any position of the nut, which is not possible with a cut edge or with a cracked edge ίο is the case. The smooth edge can also be bent back when tightening or loosening the nut is necessary.
