Abstract
Description
Die Erfindung betrifft einen windgetriebenen Ventilator, der insbesondere für Kamine oder andere abluft- und/ oder abgasführende Leitungen, Rohre, Schächte und dgl. geeignet ist.The invention relates to a wind-powered fan, who especially for Chimneys or other exhaust and / or exhaust pipes, pipes, shafts and Like. Is suitable.
Derartige windgetriebene Ventilatoren
weisen keinen motorischen Antrieb auf. Sie werden insbesondere auf
einen Kamin montiert. Ein derartiger Ventilator ist beispielsweise
in
Aufgabe der Erfindung ist es, einen windgetriebenen Ventilator zu schaffen, bei dem die Betriebssicherheit erhöht ist.The object of the invention is a to create wind-powered fan, which ensures operational safety elevated is.
Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die Merkmale des Anspruchs 1.According to the invention, the object is achieved by the features of claim 1.
Erfindungsgemäß weist der windgetriebene Ventilator eine Rotorwelle auf, die sich im Wesentlichen über die gesamte Höhe des Rotorelements erstreckt. Insbesondere erstreckt sich die Rotorwelle mindestens über die gesamte Höhe der Rotorblätter. Hierdurch ist es möglich, ein erstes bzw. unteres Lager im unteren Wellenbereich und ein zweites bzw. oberes Lager im oberen Wellenbereich anzuordnen. Die beiden Lager weisen somit einen großen Abstand auf. Dies hat zur Folge, dass die auf die einzelnen Lager wirkenden Kräfte bei hoher Windbelastung geringer sind. Da als Lager vorzugsweise Kugellager verwendet werden, gilt dies insbesondere für Kräfte, die nicht in Radialrichtung wirken und somit ein Beschädigen des Kugellagers hervorrufen können. Hierdurch ist die Betriebssicherheit des erfindungsgemäßen windgetriebenen Ventilators erheblich verbessert.According to the wind-driven fan a rotor shaft that extends essentially over the entire height of the rotor element extends. In particular, the rotor shaft extends at least over the total height of the rotor blades. hereby Is it possible, a first or lower bearing in the lower shaft area and a second or to arrange the upper bearing in the upper shaft area. The two Bearings thus have a large one Distance on. This has the consequence that the individual camp acting forces are lower in high wind loads. Because preferably as a warehouse Ball bearings are used, this applies in particular to forces that do not act in the radial direction and thus damage the Can cause ball bearings. hereby is the operational safety of the wind-driven fan according to the invention significantly improved.
Besonders bevorzugt ist es, dass die Rotorwelle im oberen Bereich insbesondere unmittelbar mit den Rotorblättern fest verbunden ist. Dies hat den Vorteil, dass das Rotorelement insgesamt steifer ausgebildet ist und die Gefahr eines Verbiegen oder Verformens des Rotorelements durch Wind verringert ist.It is particularly preferred that the rotor shaft in the upper area in particular directly with the rotor blades is firmly connected. This has the advantage that the rotor element overall is stiffer and the risk of bending or deformation of the rotor element by wind is reduced.
Die sich über die gesamte Höhe des Rotorelements erstreckende Rotorwelle ist im unteren Bereich ebenfalls mit den Rotorblättern verbunden, wobei hierbei zwischen den Rotorblättern und der Rotorwelle Stege oder Speichen vorgesehen sind. Insbesondere ist zwischen den Stegen oder Speichen und den Rotorblättern ein Ring vorgesehen. Der Ring ist vorzugsweise aus Blech hergestellt und insbesondere mit den Rotorblättern einstückig.Which extends over the entire height of the rotor element extending rotor shaft is also in the lower area with the rotor blades connected, with webs between the rotor blades and the rotor shaft or spokes are provided. In particular, is between the webs or spokes and the rotor blades a ring is provided. The ring is preferably made of sheet metal and especially with the rotor blades integrally.
In einer bevorzugten Ausführungsform ist die Rotorwelle hohl, insbesondere zylindrisch ausgebildet. Die beiden Lager sind hierbei innerhalb der Rotorwelle angeordnet. Dies hat den Vorteil, dass die Lager relativ gut vor Verschmutzung geschützt sind. Vorzugsweise ist zum Schutz des oberen Lagers die Rotorwelle am oberen Ende verschlossen. Hierdurch wird ein Eindringen von Regenwasser und Schmutz vermieden. Die Rotorwelle kann für sich genommen verschlossen sein oder durch die in diesem Bereich zusammenlaufenden Rotorblätter verschlossen werden. Vorzugsweise ist in diesem Bereich ein insbesondere kegel- oder knaufförmiger Ansatz vorgesehen, der auch als Griff genutzt werden kann. Vorzugsweise wird der Ansatz ferner zur Verbindung der Rotorblätter mit der Rotorwelle genutzt.In a preferred embodiment the rotor shaft is hollow, in particular cylindrical. The both bearings are arranged within the rotor shaft. This has the advantage that the bearings are relatively well protected against contamination. Preferably the rotor shaft is closed at the upper end to protect the upper bearing. This prevents rainwater and dirt from entering. The rotor shaft can be used for taken closed or by those converging in this area rotor blades be closed. Preferably in this area is a particular one more conical or pommel-shaped Approach provided that can also be used as a handle. Preferably the approach is also used to connect the rotor blades the rotor shaft.
Bei einer besonders bevorzugten Ausführungsform ist das untere oder erste Lager vor dem Eindringen von beispielsweise Rußpartikeln durch ein Windleitblech geschützt. Insbesondere ist hierzu ein mit der Achse verbundenes Windleitblech vorgesehen. Durch das Windleitblech werden aus dem Kamin aufsteigende Gase radial nach außen abgelenkt und gelangen somit nicht mit dem ersten bzw. unteren Lager in Kontakt.In a particularly preferred embodiment is the lower or first bearing before entering for example soot particles protected by a wind deflector. In particular, there is a wind deflector connected to the axle intended. The chimney is rising from the chimney Gases radially outwards distracted and thus do not reach the first or lower bearing in contact.
Nachfolgend wird die Erfindung anhand einer bevorzugten Ausführungsform unter Bezugnahme auf die anliegenden Zeichnungen näher erläutert.The invention is explained below a preferred embodiment with reference to the accompanying drawings.
