Description

Selbstsichericle Schraubenmutter Es sind Schraubenmuttern bekanntgeworden, die durch Kreisscheibenschnitte gebildete und zusammengedrückte Klemmbacken aufweisen., die zu einer nachgiebigen Verengung kies Muttergewindes dienen sollen. Die Nachteile der bekannten Ausführungen liegen darin, daß bei schwach gehaltenen Klemmbacken die Klemmwirkung auf den Schraubbolzen nicht ausreichend ist, während bei stärkeren Klemmbacken die i-l.as,tizität verlar:engeht, die erforderlich ist, um dem Schraubbolzen wiederholt eine stramme Aufnahme geben zu können.Self-locking screw nuts Screw nuts have become known which have clamping jaws formed by circular disk cuts and compressed., which are intended to serve as a resilient narrowing of the gravel nut thread. The disadvantages the known designs are that with weakly held jaws the clamping effect on the screw bolt is insufficient, while with stronger ones Clamping jaws the i-l.as, tität verlar: close, which is required to the screw bolt to be able to repeatedly give a tight shot.

Die Erfindung bezweckt nun, eine Schraubenmutter der eingangs geschilderten Art zu schaffen, deren Klemmbacken bei starker Klemmwirkung eine ausreichende Elastizität aufweisen., so daß sich der Gewindedurchgang stets wieder verengt, sobald.der Schraubbolzen a,us der Mutter herausgenommenwird. Dieses Ziel wird .erfindungsgemäß dadurch erreicht, daß die Mutterkrone nach außen verflachende Ringschlitze aufweist, so da13 vermehrfachte, sich gegeneinanderabstützendc und sich nach außen verkürzende Klemmbacken gebildet werden. .The invention now aims to provide a nut of the type described above Art to create the jaws of which have sufficient elasticity with a strong clamping effect have., so that the thread passage narrows again as soon as the screw bolt a, from which the mother is taken out. According to the invention, this goal is achieved by that the nut crown has ring slits that flatten outwards, so that against each other and formed clamping jaws that shorten outwards will. .

Die Zeichnung veranschaulicht ein Ausführungsbeispi.el des Gegenstandes der Erfinctung und zeigt in Fit-. i die Mutter im Längsschnitt und in Fig.2 in einer Draufsicht. Die Mutter i weist in ihrer Krone 2 zwei verschiedene Schlitzarten auf, und nvar Ringschlitze 3 und radiale Schlitze 4.. Die Anzahl der Ringschlitze 3 richtet sich nach der Wandungsstärke der Mutter t; die Tiefe der Ringschlitze 3 nimmt in Richtung des Mutterumfanges ab. Die radialen Schlitze .i, dic in üblicher Teilung geschnitten werden können, sind an ihrer Bodenseite bogenförmig ausgeführt, so, daß sle gleichfalls nach dem Mutterumfang zu an Tiefe verlieren. Diese Schnittart kann in einfachster Weise mit einer gegen die Mutterkrone 2 geführten kleinen. Kreissäge erzielt werden. Die geschnittene Krone 2 wird in üblicher Wei_=e zusammengedrückt, so daß sich alle oberen Schnittkanten der Ringschlitze 3 als auch der radialen Schlitze .4 berühren.The drawing illustrates an exemplary embodiment of the object the invention and shows in fit. i the nut in longitudinal section and in Fig.2 in a Top view. The nut i has two different types of slots in its crown 2, and nvar ring slots 3 and radial slots 4 .. The number of ring slots 3 aligns according to the wall thickness of the nut t; the depth of the ring slots 3 increases in Direction of the nut circumference. The radial slots .i, dic in the usual pitch can be cut, are curved on their bottom side, so, that they likewise lose depth according to the circumference of the mother. This type of cut can be carried out in the simplest way with a small one against the mother crown 2. circular saw be achieved. The cut crown 2 is pressed together in the usual Wei_ = e, so that all the upper cut edges of the ring slots 3 and the radial slots .4 touch.

Die Wirkungsweise der Klemmbacken 3 kommt der der g,eblockten., aus verschiedencii Längen bestehenden Blattfeder nahe, deren gute Elastizität und große Widerstandskraft an sich bekannt ist.The mode of action of the clamping jaws 3 comes from that of the g, eblockten different lengths existing leaf spring close, their good elasticity and large Resilience is known per se.
