Description

Schraubensicherung Es sind Schraubensicherungen bekannt, die aus zwei an einem Randteil verbundenen gelochten Scheiben bestehen und mit ihren mit Schraubengewinde versehenen Löchern auf das Bolzengewinde aufgeschraubt werden können. Hierbei ist durch rechtwinklige Aufbördelung der einen Scheibenseite eine Führungszunge geschaffen, die beim Zusammendrücken der beiden Scheiben einen Schrägdruck auf die obere Scheibe ausübt. Im Betriebe werden solche Sperrscheiben oft von ungelernten Arbeitern benutzt, die unnötige Kraft anwenden und die Scheiben so fest schrauben, bis beide Teile ganz gegeneinandergedrückt werden, so daß das Material eine dauernde Formveränderung erfährt und beim Abschrauben der Scheibe das Gewinde des Bolzens beschädigt wird.Screw locking There are known screw locking, which consists of two Perforated washers connected to an edge part exist and with their screw thread provided holes can be screwed onto the bolt thread. Here is A guide tongue is created by flanging one side of the pane at right angles, when the two discs are pressed together, an oblique pressure is exerted on the upper disc exercises. Such locking disks are often used in the company by unskilled workers, use the unnecessary force and screw the washers tight until both parts are completely pressed against each other, so that the material undergoes a permanent change in shape and the thread of the bolt is damaged when the washer is unscrewed.

Gemäß der Erfindung wird dieser Nachteil dadurch 'vermieden, daß von der schräg hochgebogenen Zunge, die das Widerlager zur seitlichen Verschiebung der Lochränder der Scheibe mit Bezug auf das Bolzengewinde bildet, ein durch Einschnitte hergestellter verkürzter Mittelteil nach innen an der Wurzel der Zunge eingebogen ist, so daß die Durchbiegung der an ihrem Rande geführten Scheibe zwangsläufig begrenzt wird.According to the invention, this disadvantage is avoided in that of the obliquely upturned tongue, which is the abutment for the lateral displacement of the Forms hole edges of the disc with respect to the bolt thread, one by incisions produced shortened middle part inwardly inflected at the root of the tongue is, so that the deflection of the disk guided on its edge is inevitably limited will.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Abb. z zeigt die Ausführungsform in perspektivischer Darstellung, Abb. a in Draufsicht, Abb. 3 in Seitenansicht. Die Scheibe hat an dem einen Teil a eine nach oben gebogene Zunge c, die den benachbarten Rand des andern Teils b erfaßt. Der Mittelteil d der Zunge c hat eine verkürzte Länge und ist durch Einschnitte abgetrennt und nach innen gebogen, so daß er einen die Annäherung der Teile a und b begrenzenden Anschlag bildet. Der normale Abstand des freien Endes dieses Anschlages d von der benachbarten Fläche des Teils b ist vorzugsweise so groß, daß, wenn die Scheibe so dicht aufgeschraubt wird, daß der Anschlag in Wirkung tritt, das Metall der Scheibe, und besonders an der Verbindungsstelle zwischen den beiden Teilen, nicht über die Elastizitätsgrenze beansprucht wird.An exemplary embodiment is shown in the drawing. Fig.z shows the embodiment in perspective, Fig. a in plan view, Fig. 3 in side view. The disk has a bent upward on one part a Tongue c, which grips the adjacent edge of the other part b. The middle part d the Tongue c has a shortened length and is separated by incisions and inward bent so that it has a limit stop of the approach of parts a and b forms. The normal distance between the free end of this stop d and the neighboring one Area of part b is preferably so large that when the disc is screwed on so tightly that the stop comes into effect, the metal of the disc, and especially on the junction between the two parts, not beyond the elastic limit is claimed.

Der Anschlag d kann bei dem gewöhnlichen Stanzprozeß ausgeschnitten und bei der Biegungsarbeitsstufe gebogen werden, so daß dadurch die Herstellungskosten der Scheibe nicht erhöht werden.The stopper d can be cut out in the ordinary punching process and are bent at the bending work stage, thereby reducing the manufacturing cost the disc cannot be increased.
