Description
Unterlegscheibe für Schraubenmuttern.Washer for screw nuts.
Die Neuerung liegt auf dem Gebiet der Befestigungsmittel im allgemeinen. Sie betrifft im besonderen eine Unterlegscheibe für beliebige Arten von Schraubenmuttern.The innovation lies in the field of fasteners in general. It relates in particular to a washer for any type of nut.
Das Anziehen der Schrauben mit Drehmomentschlüsseln gewinnt in der Industrie eine zunehmende Bedeutung, weil hierdurch der Sch-raube die richtige Vorspannkraft erteilt wird.Tightening the screws with torque wrenches wins in the Industry is becoming increasingly important because it gives the screw the correct preload force is granted.
Während bei kleinen Schrauben-Nenndurchmessern bis K 14 das beim Anziehen auftretende Drehmoment noch leicht aufgenommen werden kann (max. 16 mkg), macht die Aufnahme den Reaktions-Drehmomentes bei Schrauben-Nenndurchmessern M 16 bis M 3o am Werkstück größere Schwierigkeiten, die besonders dann auftreten, wenn die Muttern mit hydraulisch betriebenen Drehmomentschlüsseln stetig angezogen werden sollen.While with small nominal screw diameters up to K 14 this is the case when tightening occurring torque can still be easily absorbed (max. 16 mkg), makes the absorption of the reaction torque for screw nominal diameters M 16 bis M 3o greater difficulties on the workpiece, which occur especially when the Nuts must be tightened steadily with hydraulically operated torque wrenches should.
Die Neuerung schlägt daher einen Weg vr, bei Verwendung von Unterlegscheiben
diese so auszubilden dann sie zur Aufnahme des Reaktionsdrehmomentes mit einem Aussen-Kupplungselement
an ihrem Rand versehen werden. Ein weiteres Merkmal der Neuerung besteht darin,
die U@terlegscheibe an ihrer werkstückseitigen Auflagefläche mit einem Flächen-Kupplungselement
zu versehen.
Fig. 2 veranschaulicht in Aufsicht eine Unterlegscheibe nach der Neuerung,
deren Umfang mit zwei verschiedenen Kupplung elementen versehen ist.
Es ist erkennbar, dass sowohl für die Aussenkupplungselemente an dem
umfänglichen Teil der Unterlegscheibe bzw, an deren Rand neben den beiden dargestellten
Formen auch andere geeignete Gestaltungen in Frage kommen, eben « wie anstelle der
zahnartigen Flächenkupplungselementen 5b auch radiale oder konzentrische Zähne bzw.
Rillen be-
