Description
Um ein Lösen von Befestigungsschrauben zu vermeiden, sind unter anderem Sicherungsscheiben bekannt geworden, sogenannte Zahnscheiben, bei denen verdrehte Zähne am Umfang angeordnet sind, so daß der Druck gleichmäßig auf die Preßfläche verteilt wird. Diese Anordnung hat aber den Nachteil, daß durch Verstärkung des Preßdruckes, also Anziehen der Schrauben, die Zähne;, da sie durchTo avoid loosening of the fastening screws, locking washers are among other things become known, so-called tooth lock washers, in which twisted teeth on the circumference are arranged so that the pressure is evenly distributed over the pressing surface. However, this arrangement has the disadvantage that by increasing the pressure, so tightening of screws, teeth; as they go through
to die Verdrehung nicht genügend federn können, in das Material eingedrückt werden und dieses für erneute Verwendung unbrauchbar machen. Dies tritt besonders dann ein, wenn es sich um Metalle geringer Härte, wie Messing, Kupfer usw., handelt. Die vorliegende Erfindung beseitigt diese Nachteile- dadurch, daß die Unterlegscheibe gegenläufige, nach beiden Seiten herausgedrückte, tangential verlaufende Zungen erhält, die sich einerseits gegen die Befestigungsmutter, anderseits gegen die Unterlage legen und durch ihre Federung ein zu tiefes Eingraben in die Maschinenteile verhindern. Diese in tangentialer Richtung verlaufenden Lappen können beliebig gestaltet sein, und es ist durch djie Formgebung möglich, die erforderliche Federung der Sicherungsscheibe ?u ändern.to not be able to bend the twist sufficiently, to be pressed into the material and make it unusable for reuse. This occurs especially when the metals are of low hardness, such as brass, copper, etc. The present Invention eliminates these disadvantages, in that the washer rotates in opposite directions both sides pressed out, tangentially extending tongues received, on the one hand against the fastening nut, on the other hand against the base and through its suspension Prevent digging too deep into the machine parts. This in the tangential direction extending flaps can be designed arbitrarily, and it is due to the shaping possible, the required suspension of the lock washer ? u change.
Einige der möglichen Ausführungsformen zeigt die Zeichnung. Gemäß Abb.i sind am inneren Rand der Sicherungsscheibe rechtwinkelige Lappen gegenläufig nach beiden Drehrichtungen herausgedrückt, nach Abb. 2 befinden sich runde Lappen in gegenläufiger Anordnung in der Mitte der Sicherungsscheibe. Eine weitere Ausführungsform zeigt Abb. 3, wonach die gegenläufigen Lappen am Umfang der Sicherungsscheibe angebracht sind.Some of the possible embodiments are shown in the drawing. According to Fig.i, am inner edge of the lock washer right-angled tabs in opposite directions to both Direction of rotation pressed out, according to Fig. 2 there are round lobes in opposite directions Arrangement in the middle of the lock washer. Another embodiment is shown in Fig. 3, after which the opposing tabs are attached to the circumference of the locking washer.
