Description

Feder aus sich mittels Kegelflächen berührenden Ringen Bei den bekannten, aus in sich geschlossenen, sich mittels Kegelflächen berührenden Ringen gebildeten Federn werden bei Belastung der Feder die Außenringe auf Zug und die -InnenAnge auf Druck beansprucht; hierbei. erfahren jedoch die Außenringe bei gleichem Querscluätt wie die Innenxjnge ,erheblich größere Maximalspannungen. Die Spannungen in den Außenringen verteilen sich jedoch nicht gleichmäßig über den Querschnitt, sondern nehmen von den Berührungsflächen der Ringe aus nach der äußeren Umfläche der Außenringe hin starl: ab. Dies hat zur Folge, daß Federn dieser Art für sehr staxke Belastungen bisher ,nicht hergestellt werden konnten, da die in der Nähe der Berührungsflächen der Ringe auftretenden Spannungen die Bruchfestigkeit cbes Baustoffes übersehreitenwürden. Dieser Nacliteil tritt auch bei solchen Ringfedern auf, deren Außenringe aus einem in sich geschlossenen Ring und sich lose gegen diesen stützenden Eingsektoiren bestehen. Die Erfindung zeigt einen Weg, wie dieser Nachteil vermieden werden kann.Spring made of rings touching by means of conical surfaces. formed from self-contained rings touching one another by means of conical surfaces When the spring is loaded, springs are subjected to tension and the inner rings are subjected to tension stressed under pressure; here. however, experience the outer rings with the same Querscluätt like the inner axis, considerably higher maximum stresses. The tensions in the outer rings However, they are not distributed evenly over the cross-section, but take from the contact surfaces of the rings towards the outer circumferential surface of the outer rings starl: off. As a result, springs of this type for very high loads so far, could not be made because the close to the contact surfaces The stresses occurring in the rings would exceed the breaking strength of the building material. This nacliteil also occurs in those ring springs whose outer rings consist of a self-contained ring and loosely against these supporting insectoirs. The invention shows a way in which this disadvantage can be avoided.

Auf der Zeichnung zeigt Abb. i :ein Auisführungsheispiel des Gegenstandes der Erfindung in axialem Schnitt und Abb. leine der Abb. i entsprechende Darstellung eines zweiten Ausführungsb:eIspieles. Bei dem Ausführungsbeispiel nach Abb. i bestehen die Auß-enrünge der Feder aus je zwei. sich mit Zylinderflächien berührenden Ring en a1 und a2, vorn denen die inneren, a2, die Kegelflächen für die entsprechenden Kegelflächen der Inneminge B- der Feder tragen. Die Ringe aal und a2 jedes Federelements sind aufeinander aufgeschrumpft, so daß die Ringe a1 bereits im unie@ästeteüi Zustande der Feder auf Zug und die Ringea2 auf Druck beansprucht sind. Bei Belastung der Feder gehen die Dxucksp@annungen der Ringea' allmählich in Zugspannungen über, während die Zugspannungen ,der Ringe a1 weiter anwachsen. Hierdurch wird erreicht, daß :sich auch bei sehr hohen Belastungen die Spannungen annähernd gleichmäßig übler den ganzen Querschnitt der Außenringe verteilen, so, daß die Feder für beliebig hohe Belastungen hergestellt werden kann.In the drawing, Fig. I shows an embodiment of the object the invention in axial section and Fig. Leine of Fig. i corresponding representation of a second embodiment. In the embodiment according to Fig. I exist the outside of the spring consists of two each. ring touching cylinder surfaces en a1 and a2, in front of which the inner, a2, the conical surfaces for the corresponding Wear conical surfaces of the inner rings B- of the spring. The rings aal and a2 of each spring element are shrunk onto one another, so that the rings a1 are already in their unified state the spring is in tension and the ringsea2 are in compression. When the During the spring, the compressions of the rings gradually change into tensile stresses the tensile stresses of the rings a1 continue to increase. This achieves that: yourself even with very high loads the tensions almost uniformly worse the whole Distribute the cross-section of the outer rings so that the spring can withstand any high loads can be produced.

Bei dem Ausführungsbeispiel nach Abb.2 berühren sich je zwei einen Außenring b'gdende Ringe cl und c2 längs einer Kegelfl.äche c3, so daß :der Ring cl durch Pressen kalt auf den Ring c2 aufgezogen wenden kann. Die Anordnung ist im übrigen die gleiche wie die des ersten Ausführungsbeispieles.In the embodiment according to Fig.2, two each touch one another Outer ring b'gdende rings cl and c2 along a conical surface c3, so that: the ring cl can be turned on the ring c2 by pressing cold. The arrangement is otherwise the same as that of the first embodiment.
