Abstract

The nut comprises an upper and a lower part, and out of the upper part counter hooks (4) are bent downwards, which for drawing the nut tightly wedge into the threads of the screw due to the action of a cone (2) in the lower part of the nut. The cone (2) has guides for the counter hooks (4). The bending edges of the counter hooks (4) are adjusted by an angle of 10 - 30 deg. against the axes of the self-securing nut in the rotary direction of the screw. USE/ADVANTAGE - A self-securing nut which is effective in vibration situations and even with large temp. variations.

Description

Es ist bekannt, daß, vor allem bei Blechschraubenmuttern, bei stark vibrierenden Teilen, die mit unterschiedlichen Materialien zusammengefügt sind (Stahl/PVC), bei großen Temperatur­ schwankungen die derzeitige Sicherungswirkung nicht ausreicht. Die Schraube muß vom Schraubenkopf meist mit einer Spezialanfertigung gesichert werden.It is known that, especially with sheet metal nuts strong vibrating parts made with different materials are joined (steel / PVC), at high temperature fluctuations, the current hedging effect is insufficient. The screw must usually with a screw head Custom order can be secured.

Aufgabe der Erfindung ist es, eine selbstsichernde Mutter zu schaffen, mit deren Hilfe auf eine Sicherung des Schraubenkopfes verzichtet werden kann, so daß handelsübliche Schrauben und Unterlegescheiben verwendet werden können.The object of the invention is a self-locking mother to create, with the help of a backup of the Screw head can be dispensed with, so that commercially available Screws and washers are used can.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is characterized by the characteristics of the Claim 1 solved.

die distanzhaltende Mutter eignet sich aufgrund ihrer Eigenschaft, daß sie sich im angezogenen Zustand mit der Schraube dreht, zur Abstandsmontage verschiedener Abstände, ohne Distanzen zu unterlegen.the distance-keeping mother is suitable due to its property, that they are tightened with the screw rotates, for spaced installation of different distances, without To cover distances.

Die Plombenmutter eignete sich zum Verplomben eines ange­ schweißten Stehbolzens, sie hinterläßt beim Öffnen Spuren auf dem Gewinde.The seal nut was suitable for sealing one welded stud, it leaves traces when opened the thread.

Die Mutter besteht aus einem oberen und einem unteren Teil. Sie wird von einem Blechstreifen durch spanloses Formen her­ gestellt. Im oberen Teil befinden sich Widerhaken (4), die sich beim Festziehen der Mutter durch den Konus (2) im unteren Teil im Gewinde der Schraube verkeilen und somit eine selbstsichernde Wirkung der Mutter erzielt wird. Das untere Teil (3) kann mit verschiedenen Gewindearten versehen werden. Die Biegekanten (5) der Widerhaken (4) sind gegenüber den Achsen a, b der selbstsichernden Mutter in Drehrichtung der Schraube um einen Winkel α von 10°-30° gestellt. Die Größe desWinkels α hängt ab von der Gewindeart, dem Gewindedurchmesser und der gewünschten Sicherungswirkung. Bei der distanzhaltenden Mutter wird im oberen Teil eine Sicke (1) angebracht zur Stabilisierung und zum leichteren Links-Rechts-Drehen.The mother consists of an upper and a lower part. It is made from a sheet metal strip by non-cutting shaping. In the upper part there are barbs ( 4 ) which wedge in the thread of the screw when the nut is tightened by the cone ( 2 ) in the lower part, thus achieving a self-locking effect of the nut. The lower part ( 3 ) can be provided with different thread types. The bending edges ( 5 ) of the barbs ( 4 ) are set at an angle α of 10 ° -30 ° relative to the axes a, b of the self-locking nut in the direction of rotation of the screw. The size of the angle α depends on the type of thread, the thread diameter and the desired securing effect. For the spacing nut, a bead ( 1 ) is attached in the upper part for stabilization and for easier left-right turning.
