Description

Feder. Die Erfindung betrifft eine Verbesserung der Feder nach dem Patent 358328. Gegenstand des Patentes 358328 ist eine Feder, bei welcher sich durch den Achsialdruck ein kegelförmig abgedrehter Innenring in einen hohlkegelförmig ausgedrehten Außenring preßt, wodurch tangentiale Zug- und Druckspannungen erzeugt werden, welche eine Radialdehnung bzw. -verkürzung und hierdurch eine Achsialfederung der Dinge .hervorrufen.Feather. The invention relates to an improvement in the spring after Patent 358328. The subject of patent 358328 is a spring in which the axial pressure a conically turned inner ring into a hollow cone The machined outer ring presses, creating tangential tensile and compressive stresses which are a radial expansion or shortening and thereby an axial suspension of things.

Die vorliegende Zusatzerfindung entspricht in der Wirkung und im Prinzip zwar deni Gegenstand des Hauptpatentes, jedoch ist die bauliche Anordnung insofern abweichend, als die äußeren bzw. inneren Ringe des Hauptpatentes durch je eine Schraubenfeder ersetzt sind, derer. Profil dein der Ringe entspricht. Bei aclisialem Druck auf die ineinanderge@lreliten Schraubenfedern werden deren Keilflächen gegeneinandergepreßt, so daß die äußere Feder eine Dehnung nach außen und die innere eine Stauchuag nach innen erfährt. Würden die Enden der Schraubenfedern frei arbeiten können, so würden durch diese Formveränderungen Biegungsbeanspr uchungen in den Windungsquerschnitten auftreten. Uin an deren Stelle reine Zug- und Druckbeanspruchungen auszulösen, sind die Enden jeder Schraubenfeder derart miteinander in Verbindung, daß sie sich wohl achsial, nicht aber tangential oder radial gegeneinander bewegen können. Wie die "Zeichnung erkennen läßt, ist das eine Ende e der Feder a mit einem Rohr c fest verbunden (z. B. verschweißt), während das andere Ende f der Feder genutet ist und sich g=gen einen fest mit dem Rohr verbundenen Keil'- achsial führt. Ebenso ist das eine Ende h, der inneren Schraubenfeder h mit dein Rohr d fest verbunden, während das andere Ende i sich mittels des Keiles 1,° achsial iin Rolir _h führt.The present additional invention corresponds in effect and in principle Although the subject of the main patent, the structural arrangement is insofar different than the outer or inner rings of the main patent, each with a coil spring are replaced by those. Your profile corresponds to the rings. With aclisial pressure on the interlocking coil springs are pressed against each other by their wedge surfaces, so that the outer spring is stretched outwards and the inner spring is stretched outwards experiences inside. If the ends of the coil springs were able to work freely, so would Due to these changes in shape, bending stresses in the winding cross-sections appear. Uin instead of which pure tensile and compressive loads are to be triggered the ends of each coil spring in connection with one another in such a way that they are comfortable can move axially, but not tangentially or radially against each other. As the "Drawing shows that one end e of the spring a is fixed to a tube c connected (e.g. welded), while the other end f of the spring is grooved and g = leads axially towards a wedge that is firmly connected to the pipe. Likewise is the one end h, the inner helical spring h firmly connected to your tube d while the other end i leads axially iin Rolir _h by means of the wedge 1, °.

Erfnht ein achsialer Druck auf das System, so könnet. die Formveränderungen keine Verinehrung oder Verminderung der W indungen erzeugen, und die Folge hiervon ist eine Verli:ngerting bzw. Verkürzung der Drahtlänge. wodurch reine Zug- und Druckbeanspruchungen entstehen. Biegungsbeanspruchtingen werden nur in verschwindend geringem 'Maße auftreten, da die Durchmesserveränderung der Feder sehr gering ist. Die Rohre «-erlen entbehrlich, wenn auf jeder Federseite glas I1nde der einen Schraubenfeder mit dein der anderen derart miteinander verbunden wird, (lad sich die Tangentialspannungen aufheben.If there is axial pressure on the system, then you can. the shape changes do not produce any weakening or diminution of the coils, and the consequence thereof is a lengthening or shortening of the wire length. whereby pure tensile and compressive loads develop. Bending loads will only occur to a negligible extent, because the change in diameter of the spring is very small. The pipes "alder are dispensable, if on each spring side there is a glass of one coil spring with the other are connected to each other in such a way (let the tangential stresses cancel each other out.
