Gegenstand der Erfindung ist eine Schraubenverbindung, die durch, die Paarung eines Gewindes mit verstärkter Spitze und eines Normalgewindes gekennzeichnet ist. Die verstärkte Spitze kann sowohl am Bolzen- wie am Muttergewinde vorhanden sein. Es können auch Bolzen- und Muttergewinde an der Spitze verstärkt sein.The subject of the invention is a screw connection, which by, the pairing of a thread with a reinforced tip and a Normal thread is marked. The reinforced tip can be used on both the bolt and be present on the nut thread. There can also be bolt and nut threads on the Be reinforced tip.
Zweck der Erfindung ist, das Lösen der Schraubenverbindung zu erschweren, so daß eine zufällige Lösung ausgeschlossen wird.The purpose of the invention is to make it difficult to loosen the screw connection, so that a random solution is excluded.
Die Gewindeform ist so gewählt, daß sie möglichst wenig von normalen Gewinden abweicht und leicht herstellbar ist.The thread form is chosen so that it deviates as little as possible from normal threads and is easy to manufacture.
Beim Einschrauben der verstärkten Gewindespitzen in das Normalgewinde werdenWhen screwing the reinforced thread tips into the normal thread
