Description

  

  Sicherungsmutter.    Den Gegenstand vorliegender Erfindung  bildet eine     Sielierungsmutter.    An Hand der  beiliegenden Zeichnung wird ein     Ausfüli-          rungsbeispiel    des     Erfindungsgegenstandes          besehrieben.     



  Die Zeichnung zeigt: a Mutter in Ansieht,  <B>b</B> Mutter mit Rille<B>B</B> im Schnitt,     undefor-          miert,        c    Mutter mit Rille<B>B</B> im Schnitt, de  formiert,<B>d</B> Mutter im     Grundriss,    e Mutter  im Schnitt durch Rille     R,     <I>Form.</I>  Die     Sieherungsmutter    bestellt aus nur  einem Stück. An ihrem entlasteten Ende ist  durch eine Rille<B>B</B> ein Teil des Gewindes ab  getrennt.

   Dadurch entsteht ein     *kreisringför-          Miger    Lappen L, welcher nachdem Hauptteil  des Gewindes zu eingestaucht wird     (Fig.        c).     Das Mass der     Einstauellung    beträgt auf dem  Gewindedurchmesser gemessen weniger a s  die halbe Steigung des Gewindes. Die Dick  des Lappens. variiert     jee    nach Gewindes     igung,          Güwindeduro,hmesser    und Material der r.  



  <I>Wirkungsweise.</I>  Beim Einschrauben des Schraubenbolzens  wird der     deforinierte    kreisringförmige Lap-         pen    L wieder in die ursprüngliche     undefor-          mierfe    Lage gedrückt. Dadurch entstehen  innere Kräfte, welche bewirken,     dass    das       Bolzengewinde    zwischen Lappen- und Trag  gewinde eingeklemmt wird. Der tragende  Teil der Mutter liegt stets auf derselben     Ge-          windeflankenseite    auf, ob die Mutter be  lastet ist oder nicht.

   Die Bewegung des kreis  ringförmigen Lappens L zwischen gelöstem  und eingeschraubtem Zustand ruft Spannun  gen hervor, welche, wie Versuche gezeigt  haben, unterhalb der     El#astizi%tsgrenze    liegen.



  Lock nut. The subject of the present invention is a sieling nut. An exemplary embodiment of the subject matter of the invention is described on the basis of the accompanying drawing.



  The drawing shows: a nut in view, <B> b </B> nut with groove <B> B </B> in section, undeformed, c nut with groove <B> B </B> in section, de formed, <B> d </B> nut in plan, e nut in section through groove R, <I> shape. </I> The lock nut ordered from just one piece. At its relieved end, part of the thread is separated by a groove <B> B </B>.

   This creates a circular flap L, which is inserted after the main part of the thread (Fig. C). The extent of the damming measured on the thread diameter is less than half the pitch of the thread. The thick of the rag. varies depending on the thread pitch, Güwindeduro, diameter and material of the r.



  <I> How it works. </I> When the screw bolt is screwed in, the deforinated circular flap L is pressed back into the original undeformed position. This creates internal forces which cause the bolt thread to be pinched between the flap thread and the support thread. The load-bearing part of the nut always rests on the same thread flank side, whether the nut is loaded or not.

   The movement of the circular ring-shaped flap L between the loosened and screwed-in state causes stresses which, as tests have shown, are below the elastic limit.

 

Claims (1)

PATENTANSPRUCH: Sicherungsmutter, gekennzeichnet da durch, dass an ihrem einen Ende ein Teil des Gewindes durch eine Rille abgetrennt ist, wodurch ein kreisringförmiger Lappen gebil- d#et ist, welcher, über einen hohlzylindrischen Steg mit dem Ilauptteil der Mutter verbun den, in Richtung des Hauptgewindeteils de formiert und dazu bestimmt ist, das einge schraubte Bolzengewinde festzuklemmen. PATENT CLAIM: Lock nut, characterized in that at one end part of the thread is separated by a groove, whereby an annular tab is formed which, via a hollow cylindrical web, is connected to the main part of the nut in the direction of the main thread part is deformed and intended to clamp the screwed-in bolt thread.
