Description
sicherungamutter. Gegenstand vorliegender Erfindung ist eine Sicherungsmutter, welche insbesondere für Schraubenverbindungen an Maschinen teilen bestimmt ist, die Erschütterungen aus gesetzt sind. Erfindungsgemäss besitzt die Sicherungsmutter einen Ansatz, welcher min destens einen Schlitz aufweist. Der äussere Gewindedurchmesser der Mutter verkleinert sich allmählich auf der Länge des Ansatzes, während der innere Gewindedurchmesser auf der ganzen Länge der Mutter konstant bleibt.
In der beiliegenden Zeichnung ist ein Aus führungsbeispiel der Erfindung im Schnitt dargestellt. Die dargestellte Mutter 1 besitzt einen konischen Ansatz 2 (honuswinkel etwa 250), welcher mindestens einen Schlitz 3 auf weist. Der innere Gewindedurchmesser d ist auf der ganzen Länge der Mutter konstant, der äussere Gewindedurchmesser dl dagegen bleibt zuerst konstant und nachher verklei nert er sich allmählich auf der Länge des An satzes, gleich dem Durchmesser einer koni- sehen Fläche, mit einem Winkel von etwa<B>22</B> bis 60.
Wird nun eine Schraube, deren Durch messer demjenigen des untern Teils der Mut ter entspricht, eingeschraubt, so wird, sobald das Schraubenende in den obern Teil der Mut ter kommt., der Ansatz 2 auseinandergedrückt, was durch den Schlitz 3 ermöglicht wird. Durch die elastische Wirkung des Ansatzes 2 entsteht auf der Länge dieses Ansatzes eine erhöhte Reibung, was das selbsttätige Lösen der Schraubenverbindung verhindert. Die Stärke der Reibung kann je nach Verwen dungszweck der Sicherungsmutter gewählt werden.
backup mother. The present invention is a lock nut, which is intended to share in particular for screw connections on machines that are set from vibrations. According to the invention, the lock nut has an approach which has at least one slot. The outer thread diameter of the nut gradually decreases along the length of the attachment, while the inner thread diameter remains constant along the entire length of the nut.
In the accompanying drawing, an exemplary embodiment from the invention is shown in section. The nut 1 shown has a conical extension 2 (honing angle about 250), which has at least one slot 3. The inner thread diameter d is constant over the entire length of the nut, while the outer thread diameter dl remains constant at first and then gradually decreases along the length of the attachment, equal to the diameter of a conical surface, with an angle of about < B> 22 </B> to 60.
If a screw, the diameter of which corresponds to that of the lower part of the mother, is screwed in, as soon as the screw end comes into the upper part of the mother, the shoulder 2 is pushed apart, which is made possible by the slot 3. Due to the elastic effect of the attachment 2, there is increased friction along the length of this attachment, which prevents the screw connection from loosening automatically. The strength of the friction can be selected depending on the purpose of the lock nut.
