Description

Spiral- oder schraubenförmig gewundene Federn für große elastische Kraftaufnahme werden gemäß dem Stande der Technik meist derart in Metall ausgeführt, daß durch Wikkein von Stabmaterial oder aber auch Ausarbeiten aus dem Vollmaterial die Feder mit dem der Beanspruchung entsprechenden Windungsquerschnitt gebildet wird. Erfordert nun die Beanspruchung einen sehr großen Windungsquerschnitt, so ergeben sich erhebliche Herstellungsschwierigkeiten bei einem sehr nachteiligen außerordentlich hohen Gewicht solcher Federn.Spiral or helically wound springs for large elastic force absorption are usually carried out in metal according to the prior art in such a way that Wikkein of rod material or also elaboration from the solid material, the spring with the winding cross-section corresponding to the stress is formed. If the stress now requires a very large winding cross-section, the result is considerable Manufacturing difficulties with a very disadvantageous extremely high weight such feathers.

Diese Nachteile sollen erfindungsgemäß dadurch vermieden werden, daß die Federn aus einer entsprechend großen Anzahl von dünnen Holzplatten bestehen, welche mit ihrer Faserrichtung hauptsächlich annähernd senkrecht zum Windungsquerschnitt ver-These disadvantages are to be avoided according to the invention in that the springs consist of a correspondingly large number of thin wooden panels, which with their fiber direction mainly approximately perpendicular to the winding cross-section.

ao laufend miteinander verleimt sind. Derartige Federn haben eine große Elastizität und Festigkeit und sind hinsichtlich Belastbarkeit und Federungsarbeit einer Feder aus Stahl bei gleichem Gewicht überlegen.ao are continuously glued together. Such springs have great elasticity and Strength and are made of a spring in terms of resilience and suspension work Superior to steel for the same weight.

Bisher zur Kraftübertragung benutzte a5 elastische hölzerne Maschinenteile besaßen zumeist Stab- oder Plattenform. A 5 elastic wooden machine parts that were previously used for power transmission were mostly in the form of rods or plates.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. Durch'Verleimen dünner Holzplatten a, b, c, d,' e, deren Faserrichtung annähernd senkrecht zu dem rechteckigen Windungsquerschnitt f verläuft, ist eine spiralförmig gewundene Feder gebildet.An exemplary embodiment of the subject matter of the invention is shown in the drawing. By gluing thin wooden panels a, b, c, d, 'e, the fiber direction of which is approximately perpendicular to the rectangular winding cross-section f , a helically wound spring is formed.

Die Herstellung selbst kann in bekannter Weise durch Aufwickeln der dünnen Holzplatten auf eine wieder zu entfernende gewundene Metallschablone oder biegsame Wickelbeilage und durch gegenseitiges Verleimen erfolgen.The production itself can be done in a known manner by winding up the thin wooden panels on a twisted metal template to be removed or flexible wrapping insert and by gluing them together take place.

Die derartig erzeugten Holzfedern weisen außer den bekannten Festigkeitsvorzügen desThe wood springs produced in this way have the well-known strength advantages of the

Schichtholzaufbaues auch den Vorteil auf, daß sie nur eine geringe Formveränderung unter dem Einfluß von Feuchtigkeit erfahren, da ein Quellen, Werfen und Schwinden nur noch in geringen, die Brauchbarkeit nicht mehr beeinträchtigendem Maße stattfinden kann. Die konservierende Wirkung neuzeitlicher Leime vermindert wesentlich und ausreichend die Fäülnisgefahr des Holzes, so daß derartige Holzfedern, welche größte Säure- und Rostbeständigkeit besitzen, bei ihrem geringen spezifischen Gewicht in vielen Fällen, als Maschinenelement Metallfedern ersetzen und oft denselben bedeutend überlegen sind, zumal sich durch die Behandlung mit entsprechenden' Schutzstoffen auch die Feuersgefahr ganz wesentlich vermindern läßt.Laminated wood structure also has the advantage that there is only a slight change in shape under the influence of moisture, there is only swelling, throwing and shrinking still take place to a small extent that no longer adversely affects the usability can. The preserving effect of modern glues significantly and sufficiently reduces the risk of decay of the wood, see above that such wooden springs, which have the greatest acid and rust resistance, at Due to their low specific weight, metal springs are used as machine elements in many cases replace and are often significantly superior to the same, especially as the treatment with appropriate 'protective materials also reduce the risk of fire very significantly leaves.
