Anlage 1 zu Gebrauchsmusteranmeldung "Ganzmetall-SicherheitSBchraube" v. 12. 4.1973Appendix 1 to utility model registration "All-metal security screw" v. 12/4/1973
A. Beschreibung der Ganzmetall-Sicherheitsschraube ■A. Description of all-metal security screw ■
Die Neuerung bezieht sich auf eine Sicherheitsschraube bzw. auf ein Sicherheits-Bolzengewinde bei welchem das Sicherungsmoment bzw. die Klemmkraft durch eine, an einer oder mehreren Stellen des Gewindeumfangs punkt- oder/und linienförmig in gleicher oder gegenläufiger Richtung angebrachte Verformung der Gewindesteigung bewirkt wird.The innovation relates to a safety screw or a safety bolt thread in which the locking torque or the clamping force by one, at one or more points on the thread circumference point or / and linear in the same or opposite direction attached deformation of the thread pitch is caused.
Anzahl, Sichtung und Volumen der Gewindesteigungsverformung bzw. der Verformungszonen wird in Abhängigkeit von Gewinde-Durchmeaser, Gewinde-Steigung und geforderter Klemmkraft bzw. gefordertem Sicherungsmoment festgelegt.Number, classification and volume of the thread pitch deformation or the deformation zones are determined depending on the thread diameter, Thread pitch and required clamping force or required securing torque are specified.
Die Neuerung ist für Schrauben bzw. Bolzengewinde aus allen metallischen Werkstoffen anwendbar.The innovation is for screws or bolt threads made of all metallic ones Materials applicable.
Es gibt zwar schon Sicherheiteschrauben, bei welchen die Klemmkraft bzw. das Sicherungsmoment durch Einsetzen von Kunststoff-Pfropfen oder -Leisten oder durch Aufbringen von Kunststoff-Schichten bewirkt wird. Diese Sicherheitsschrauben haben den großen Nachteil, daß Kunststoff nur beschränkt temperaturbeständig ist und somit die Temperaturbeständigkeit des Schrauben·»· Werkstoffes nicht genutzt werden kann und beim Einsetzen von Kunststoff-Pfropfen oder -Leisten der Querschnitt des Schraubenbolzens geschwächt wird. Des weiteren wird die in den einschlägigen Deutschen Normen geforderte Erhaltung des Sicherungsmoments bei Wiederhol-Verschraubungen nur bedingt gewährleistet. D.h., das Sicherungsmoment fällt bei wiederholter Verwendung der Sicherheitsschraube teilweise unzulässig ab.There are already safety screws with which the clamping force or the securing torque by inserting plastic plugs or strips or by applying layers of plastic is effected. These safety screws have the major disadvantage that plastic has only limited temperature resistance and thus the temperature resistance of the screw · »· Material cannot be used and when inserting plastic plugs or strips, the cross-section of the screw bolt is weakened. Furthermore, the maintenance of the locking torque required in the relevant German standards only guaranteed to a limited extent for repeated screw connections. This means that the locking torque drops when the safety screw is used repeatedly partly inadmissible from.
Die Neuerung dient dem Zweck, die vorstehenden Mangel bei gleichzeitiger Senkung der Fertigungskosten zu beseitigen.The innovation serves the purpose of eliminating the foregoing deficiency at the same time Eliminate lowering manufacturing costs.
Die durch Formstempel erzeugte Veränderung des Gewindeoteigungsverlaufs gestattet die Nutzung der Temperaturbeständigkeit des Schraubenwerkstoffes und gewährleistet Klemmkräfte bzw. Sicherungsmomente und Wiederhol-Verschraubung gemäß DIN 267, Blatt 15. The change in the thread pitch produced by the form punches allows the use of the temperature resistance of the screw material and guarantees clamping forces or locking torques and repeated screwing in accordance with DIN 267, sheet 15.
D:ie Neuerung wird beispielsweise dargestellt durch Abbildung 1, 2 und 3.The innovation is illustrated, for example, by Figure 1, 2 and 3.
