Description
Die Erfindung bezieht sich auf die Ausgestaltung von Federn, insbesondere Spiral- oder Schraubenfedern. Nach dem Patent 802 363 wird eine Einsparung des Raumes bei gleicher Leistung dadurch bewirkt, daß der Bandfeder ein gekrümmter Querschnitt gegeben wird. Die Krümmung kann außerdem auf die Länge des Bandes unterschiedliche Stärke haben.The invention relates to the design of springs, in particular spiral or helical springs. According to the patent 802 363, space is saved with the same performance by giving the ribbon spring a curved cross-section. The curvature can also have different strengths along the length of the band.
Die Kanten der Bandfedern und insbesondere derjenigen mit gekrümmtem Querschnitt werden besonders stark beansprucht und reißen leicht ein. Außerdem berühren sich bei einer Spiralfeder im aufgewickelten Zustand die ganzen Flächen der einzelnen Windungen und bewirken durch die größere Reibung eine Beeinträchtigung der Federleistung: Gemäß der Erfindung werden diese Nachteile durch eine Verstärkung der Federkanten behoben. Unter Berücksichtigung der Randverstärkungen tritt durch eine zweckmäßige Ausgestaltung des Querschnittes bei gekrümmten Federn außerdem eine Schwerpunktsverlagerung auf, die sich vorteilhaft gerade auf die besonders beanspruchten Kanten der Feder und damit ihre Leistungsfähigkeit auswirkt. Dies ist beispielsweise der Fall, wenn der Querschnitt der Feder so geformt ist, daß sein Schwerpunkt möglichst in Richtung nach dem Krümmungsmittelpunkt hin verlagert wird.The edges of the ribbon springs and especially those with curved ones Cross-sections are particularly stressed and tear easily. Also touch In the case of a spiral spring, the entire surfaces of the individual are in the coiled state Windings and cause an impairment of the spring performance due to the greater friction: According to the invention, these disadvantages are alleviated by a reinforcement of the spring edges Fixed. Taking into account the edge reinforcements occurs through an expedient Design of the cross-section in the case of curved springs also includes a shift in the center of gravity on, which is advantageous especially on the particularly stressed edges of the spring and thus affects their performance. This is the case, for example, when the cross section of the spring is shaped so that its center of gravity is as possible in the direction is shifted towards the center of curvature.
In der Zeichnung sind zwei; erfindungsgemäße Beispiele dargestellt, und zwar zeigt Fig. i eine Bandfeder mit -gestrecktem Querschnitt, Fig.2 eine Bandfeder mit kreisbogenförmigem Querschnitt, Fg. 3 eine Spiralfeder nach Fig. i -im aufgezogenen Zustand.In the drawing are two; Examples according to the invention shown, namely, FIG. 1 shows a band spring with an elongated cross section, FIG. 2 shows a band spring with a circular arc-shaped cross-section, FIG. 3 shows a spiral spring according to FIG State.
Bei der Bandfeder reit gekrümmtem Querschnitt und Randverstärkung V (Fig. 2) ist der Schwerpunkt S im Vergleich zu einer Feder ohne Randverstärkung in Richtung der Kanten verschoben. Dadurch ist zwar die Beanspruchung in der Mitte M der Bandfeder etwas größer, die der weitaus höher beanspruchten Kanten jedoch kleiner geworden.The band spring has a curved cross-section and edge reinforcement V (Fig. 2) is the center of gravity S compared to a spring without edge reinforcement shifted towards the edges. As a result, the stress is in the middle M of the band spring is somewhat larger, but that of the edges that are subject to much higher stress got smaller.
In Fig. 3 ist gezeigt, wie sich die einzelnen Windungen im aufgezogenen Zustand der Feder nur in zwei Linien L1; L2 berühren.In Fig. 3 it is shown how the individual turns in the open Condition of the spring only in two lines L1; Touch L2.
