Description
Schraubensicherung. Die Erfindung betrifft eine Schraubensicherung, bei der die Mutter vor dem Gebrauch nur auf einem Teil ihrer Höhe mit Gewinde versehen ist, während das Gewinde auf dem übrigen Teil durch den Bolzen selbst beim Eindrehen geschnitten wird. Derartige bisher bekannte :Muttern besitzen den Nachteil, daß sie nach einmaliger Benutzung weggeworfen werden müssen und auch die Anfertigung Schwierigkeiten mit sich bringt.Screw locking. The invention relates to a screw locking device, in which the nut is only threaded at part of its height before use is, while the thread on the rest of the part through the bolt itself when screwing is cut. Such previously known: nuts have the disadvantage that they have to be thrown away after a single use and also the production Brings difficulties.
Gemäß der Erfindung besteht der Teil der Mutter, worin vor der Benutzung kein Gewinde eingeschnitten ist, aus einer Einlage von einem Metall oder einer Legierung, die weicher ist als der übrige Teil der Mutter und derart hierin angebracht ist, daß dieser mit dem übrigen Teil der Mutter ein Ganzes bildet.According to the invention, the part of the mother consists in which before use no thread is cut from an insert of a metal or an alloy, which is softer than the rest of the nut and is attached in such a way that that this forms a whole with the rest of the mother.
In der Zeichnung, worin ein Ausführungsbeispiel dargestellt ist, zeigt Abb. i einen senkrechten Schnitt ohne und Abb. 2 einen senkrechten Schnitt mit eingeschraubtem Bolzen.In the drawing, in which an embodiment is shown, shows Fig. I a vertical section without and Fig. 2 a vertical section with a screwed in Bolt.
In der Mutter i ist eine Aussparung 2 vorgesehen, welche mit einem weichen Metall oder einer Legierung, z. B. Blei und Zinn oder Babbit, ausgefüllt wird. Dieser Teil ist an seiner Innenseite glatt und sein Innendurchmesser -gleich dem Kerndurchmesser des Gewindes.In the mother i a recess 2 is provided which with a soft metal or alloy, e.g. B. lead and tin or Babbit filled will. This part is smooth on the inside and the same inside diameter the core diameter of the thread.
In die Wand der Mutter i sind Löcher 3 gebohrt, worin beim Guß auch Metall fließt und wodurch verhindert wird, .daß die Einlage sich mit dem Bolzen mitdreht. Statt Löcher können auch Längsnuten o. dgl. angebracht werden. Beim Einschrauben des Bolzens schneidet dieser sich in das weiche Metall ein und wird derart festgehalten, daß er jeder Erschütterung widersteht, ohne sich zu lösen. Diese Muttern sind besonders dort anzuwenden, wo die Maschinenteile sich durch starke Erschütterungen leicht lösen und jeden Augenblick angezogen werden müssen.In the wall of the nut i holes 3 are drilled, in which also during the casting Metal flows and this prevents .that the insert is attached to the bolt turns. Instead of holes, longitudinal grooves or the like can also be made. When screwing in of the bolt, it cuts into the soft metal and is held in place in such a way that it that it withstands every shock without loosening. These nuts are special To be used where the machine parts can easily be moved by strong vibrations and must be tightened every moment.
Wenn die Mutter gelöst ist, kann auf einfache Weise durch Erwärmung die Einlage entfernt und eine neue Einlage angebracht oder die alte Einlage in den ursprünglichen Zustand zurückgebracht werden.When the nut is loosened, it can be easily done by heating the inlay removed and a new inlay attached or the old inlay in the be returned to original condition.
