Description
Die Erfindung betrifft einen als Bolzen, Gittersta#b; ' Achse; Welle -bzw. Wellenzapfen, Torsionsstab u.:dgl. geeigneten, im wesentlichen zylindrischen, in sich .elastischen Konstruktionsteil.The invention relates to a bolt, lattice rod; 'Axis; wave -respectively. Shaft journal, torsion bar, etc. suitable, essentially cylindrical, in itself .elastic construction part.
Im Gegensatz zu: der herkömmlichen- starren bzw. massiven Ausführung solcher Maschinen- oder Konstruktionselemente ist der neue Konstruktionsteil durch die konzentrische Verbindung eines federnden, der Länge nach schraubenförmig oder sonst irgendwie geschlitzten und eines gleichfalls federnden, ungeschlitzten Hohlzylinders gekennzeichnet.In contrast to: the conventional rigid or solid design of such machine or construction elements, the new construction part is through the concentric connection of a resilient, lengthwise helical or otherwise somehow slotted and an equally resilient, unslotted hollow cylinder marked.
Hierdurch ergeben sich gegenüber als einfacTe Hohlzylinder oder als massive Zylinder ausgebildeten Wellen, Bolzen, Zapfen usw, sehr beachtliche Vorteile hinsichtlich Abscherkraft, Torsionsfestigkeit und Festigkeit bei Dauerwechselbeanspruchung. Eine mäßige Ersparnis an Gewicht verdient ebenfalls erwähnt zu werden. Besonders zu beobachten ist jedoch, :daß bei hoher Beanspruchung nur der äußere, an Wandstärke um .die Hälfte schwächere Hohlzylinder aus legiertem, beispielsweise etwa r °/o Chrom enthaltendem Stahl hergestellt wird, während für den inneren in der Regel Mangan-Silicium-Stahl in Frage kommt. Zur axialen-Sicherung ,eines im Sinri der Erfindung ausgebildeten Bolzens od. @dgl. dienen Splinte od. dgl., welche von außen oder von innen durch die einfache Wandung des 'verlängerten Endes eines .der Zylinder, vorzugsweise des ungeschlitzten äußeren Zylinders, getrieben wenden.This results in a simple hollow cylinder or as a massive cylinder formed shafts, bolts, journals, etc., very considerable advantages with regard to shear force, torsional strength and strength under cyclical stress. A moderate weight saving also deserves mention. Particularly What can be observed, however, is that: in the case of high stress only the outer wall thickness Hollow cylinders made of alloyed alloy, for example about r ° / o, are half weaker Chromium-containing steel is made, while for the interior usually Manganese-silicon steel comes into question. For axial security, one in the Sinri der Invention trained bolt od. @ The like. Serve cotter pins or the like, which from the outside or from the inside through the simple wall of the 'extended end of one of the cylinders, preferably of the unslotted outer cylinder, driven.
In der Zeichnung ist- ein Ausführungsbeispiel der Erfindung im Aufriß, Grund@riß und Schnitt dargestelit. Ein schraubenförmig geschlitzter, federn-.der Hohlzylinder i ist mit Vorspannung in einen ungeschlitzten, ebenfalls federnden Hohlzylinder z angeordnet, dessen Wandstärke etwa halb so groß ist wie die des geschlitzten Zylinders.In the drawing is an embodiment of the invention in elevation, Basic crack and section shown. A helically slotted, spring-loaded .der Hollow cylinder i is preloaded into an unslotted, also resilient one Hollow cylinder z arranged, the wall thickness of which is about half as large as that of the slotted Cylinder.
Der Rahmen der Erfindung wird offenbar auch nicht verlassen, wenn statt :der Kombination eines geschlitzten und eines ungeschlitzten Zylinders lediglich Kombinationen von geschlitzten oder ungeschlitzten Zylindern in Betracht gezogen wer-.den. Die übliche Verwendung sogenannter Verbundspannstifte oder -hülsen wird hiervon natürlich nicht berührt.The scope of the invention is evidently not left if instead of: the combination of a slotted and an unslotted cylinder only Combinations of slotted or unslotted cylinders are contemplated will. The usual use of so-called composite dowel pins or sleeves is of course not affected by this.
