Description
Sicherung für Schraubenverbindung Die Erfindung bezieht sich auf Schraubensicherungen nach Patent 635 553 in Form von U.nterlegscheiben mit am Rande befindlichen Bremsteilen in Form von verdrehten Zähnen, Zinken, Zacken oder Blättern, die nebeneinander fächer- oder irisblendenaxtig angeordnet sind. Die Wirkung derartiger Sicherungen beruht darauf, daß beim Anziehen der Schraubenverbindun:g die verdrehten Teile in Richtung Ausgangsstellung zurückgebogen und in federnder Stellung festgehalten werden. Um die Federwirkung sicherzustellen, daxf man von einer bestimmten Blechstärke nicht abgehen. Daher ist die Bremskraft bei den bisher bekannten Sicherungsscheiben gerade bei den kleineren Durchrnesswrn unverhältnismäßig groß.Securing for screw connections The invention relates to screw securing according to patent 635 553 in the form of U. washers with braking parts located on the edge in the form of twisted teeth, prongs, prongs or leaves, which are arranged next to each other in a fan or iris aperture ax. The effect of such safeguards is based on the fact that when the screw connections are tightened, the twisted parts are bent back towards the starting position and held in a resilient position. In order to ensure the spring action, one must not deviate from a certain sheet metal thickness. Therefore, the braking force in the previously known locking washers is disproportionately large, especially with the smaller diametres.
Zweck der Erfindung ist es daher, die Bremsteile der Scheiben nicht gleichwitig,, sondern nach und nach anzuspannen und die volle Belastung der Mutter ioder des Schraubenkopfes allmählich durchzuführen. Die Wirkung wird also steigerungsfähig. Sie kann den jeweiligen Erfordiernissen, die z. B. bei Stahl, Messing, Bronze und Leichtmetall verschieden sind, so angepaßt werden, daß sie sich während des Anziehens der Schraubenverbindung erst voll entwickelt.The purpose of the invention is therefore not the brake parts of the discs indifferent, but gradually tightening and putting the full burden on the mother ior the screw head gradually. The effect can therefore be increased. You can meet the respective requirements that z. B. in steel, brass, bronze and Light metal are different, so adjusted that they move during tightening the screw connection is only fully developed.
Die Abb. z und z zeigen in der Mitte jede einen Zahn, der im Vergleich zu dem rechts und links davon schärfer verdreht ist.Figs. Z and z each show a tooth in the middle, which is compared to which it is more sharply twisted to the right and left of it.
