Description
Die Erfindung betrifft eine Schraubenmutter, insbesondere für auf Abscherung beanspruchte Schraubenbolzen. Die bisher bekannten Schraubenmuttern haben den Nachteil des zu hohen Gewichtes, da sie aus dem Vollen gearbeitet sind. Ein weiterer Nachteil besteht auch darin, daß. der Gewindegang quer zur Materialfaser geschnitten ist. Hierdurch wird die Festigkeit bedeutend herabgemindert.. The invention relates to a screw nut, especially for screw bolts subject to shear stress. The ones known so far Screw nuts have the disadvantage of being too heavy because they come from the Are fully worked. Another disadvantage is that. the thread is cut across the material fiber. This significantly reduces the strength.
Diese Nachteile sucht die Erfindung zu beseitigen, indem die Mutter als flache Kapselmutter ausgebildet ist, die aus zwei ineinandergreifenden Teilen 1 und 2 besteht, deren Bodenflächen je einen angepreßten Gewindegang besitzen. Die beiden ineinandergesteckten Teile 'wirken wie eine Mutter. Es ergeben sich dadurch verschiedene Vorteile: Einmal 1WJXd das Gewicht, -wie ersichtlich, be-The invention seeks to eliminate these disadvantages by designing the nut as a flat cap nut, which consists of two interlocking parts 1 and 2, the bottom surfaces of which each have a pressed-on thread. The two nested parts' act like a nut. This results in various advantages: Once the weight is 1 WJXd, as can be seen,
ao deutend herabgemindert. Die Herstellung ist eine schnellere, -wodurch sich also die Herstellungskosten verbilligen. Es wird dadurch auch die Bauhöhe herabgemindert, ohne daß die Festigkeit leidet, Ein Weiterer Vorteil besteht darin, daß ein Baustoff gewählt werden kann, dessen Verwendung bisher unverhältnismäßig große Schwierigkeiten und infolgedessen auch Kosten verursachte.ao interpreting downgraded. The production is faster, which means that the production costs are reduced cheaper. This also reduces the overall height without sacrificing strength. There is a further advantage in the fact that a building material can be selected, its use so far disproportionate caused great difficulties and consequently also costs.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing.
Abb. ι stellt die neue Schraubenmutter dar. InFig. Ι represents the new nut in this
Abb. 2 ist die neue Schraubenmutter im Schnitt nach Linie A-B der Abb. 1 gezeigt, währendFig. 2 shows the new nut in section along line AB of Fig. 1, while
Abb. 3 die beiden Teile der Schraubenmutter auseinandergezogen darstellt.Fig. 3 shows the two parts of the nut pulled apart.
Mit ι und 2 sind die beiden kapselajtig ausgeführten Teile der Mutter bezeichnet, ~die ineinandergreifen. 3 ist der angepreßte Gewindegang. Die 'einzelnen Teile können mehr oder weniger hoch, gewählt werden. Diese beiden Teile r und 2 können gemäß dem dargestellten Ausführungsbeispiel ineinandergesteckt weiden, so daß ein mehr oder weniger hoher Hohlraum entsteht, der zur Aufnahme von konsistentem Fett, ölgetränkten Filzeinlagen o. dgl. oder aber auch zur Aufnahme einer Scheibe dient. Die beiden Teile 1 und 2 können aber auch kapselartig so ineinandergesteckt werden, daß die entsprechenden Bodenflächen aneinander anliegen.With ι and 2, the two are capsule-dependent executed parts of the mother, ~ which interlock. 3 is the pressed-on thread. The 'individual parts can be chosen to be more or less high. These both parts r and 2 can be plugged into one another according to the illustrated embodiment graze, so that a more or less high cavity is created, which is used to hold consistent fat, oil-soaked felt inserts o. The like. Or is used to accommodate a disc. The two parts 1 and 2 but can also be plugged into each other like a capsule so that the corresponding bottom surfaces rest against each other.
