Rotor zum Umwandeln der Energie des natürlichen Windes in nutzbare mechanische EnergieRotor for converting the energy of the natural wind into usable mechanical energy
Die Erfindung betrifft einen Rotor zum Umwandeln der Energie des natürlichen Windes in nutzbare mechanische Energie, bestehend aus wenigstens zwei langgestreckten, gekrümmten Windflügeln, die vorzugsweise gegenüberliegend auf der Drehachse des Rotors angeordnet sind.The invention relates to a rotor for converting the energy of the natural wind into usable mechanical ones Energy, consisting of at least two elongated, curved wind blades, which are preferably arranged opposite one another on the axis of rotation of the rotor.
Rotoren dieser Art sind seit langem unter dem Namen "Savonius-Rotor" bekannt. Bei diesen Rotoren sind die einzelnen Windflügel parallel zur Drehachse verlaufend angeordnet. Bei diesen Rotoren wird bei Stellung der Windflügel quer zur Windrichtung die volle Windkraft und bei Stellung der Windflügel in Windrichtung (besonders bei zweiflügeligen Rotoren) theoretisch keine Windkraft übertragen. Dieses ständige Alternieren der beiden extremen Windkraftübertragungswerte beim Rotieren dieser Rotoren führt zu einem stoßweisen, unruhigen Lauf, wodurch Vibrationen auf den Turm, an welchem die Rotoren gelagert sind, übertragen werden. Diese Vibrationen können bei größeren Windstärken so erheblich sein, daß eine besondere Auslegung des TurmesRotors of this type have long been known under the name "Savonius rotor". With these rotors they are individual wind blades arranged parallel to the axis of rotation. With these rotors, the position of the Wind blades across the wind direction the full wind power and when the wind blades are positioned in the wind direction (especially in the case of double-bladed rotors) theoretically no wind power is transmitted. This constant alternation of the two extreme wind power transmission values when rotating these rotors leads to an intermittent, uneven running, whereby vibrations are transmitted to the tower on which the rotors are mounted. These vibrations can be so significant at higher wind speeds that a special design of the tower

- 3 erforderlich ist.- 3 is required.
Besonders nachteilig hat sich dieser Umstand ausgewirkt bei Windkraftwerken, wo zwei solche Rotoren zusammen auf einem drehbar an dem Turm gelagerten Lagerbock angeordnet sind. Diese drehbare Anordnung ist bei mehreren zusammenwirkenden Rotoren erforderlich, damit sich die Anlage stets von selbst in die optimale Richtung zum Wind stellt. Windboen und schnelle Windrichtungsänderungen führen hier durch die wechselweise volle Beaufschlagung der Windflügel zusätzlich zu einem Hin- und Herpendeln des gesamten Lagerbockes. Bei größeren Windstärken tritt ein so starkes Aufschaukeln dieser Pendelbewegungen ein, daß solche Anlagen wirtschaftlich nicht mehr betrieben werden können.This fact has had a particularly disadvantageous effect in wind power plants, where two such rotors come together are arranged on a bearing block rotatably mounted on the tower. This rotatable arrangement is with several interacting rotors required so that the system always automatically moves in the optimal direction to the wind. Wind gusts and rapid wind direction changes lead through the alternately full application of the wind blades in addition to a back and forth oscillation of the entire bearing block. In the case of greater wind strengths, these pendulum movements build up so strongly that such systems can no longer be operated economically.
Aufgabe der Erfindung war es daher, Rotoren zu schaffen, die einerseits gleichmäßiger laufen und andererseits ein Aufschaukeln der Pendelbewegungen beim Zwillingsbetrieb von Rotoren auf einem drehbaren Lagerbock verhindern. The object of the invention was therefore to create rotors, which, on the one hand, run more evenly and, on the other hand, prevent the pendulum movements from rocking when the rotors are in twin operation on a rotatable bearing block.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die einzelnen Windflügel des Rotors wendelförmig um die Drehachse verdreht angeordnet sind. Hierbei stehen die Windflügel nie senkrecht zur Windrichtung, sondernThis object is achieved according to the invention in that the individual blades of the rotor are arranged helically rotated around the axis of rotation. Stand here the wind blades never perpendicular to the wind direction, but

immer etwas schräg, so daß ein Teil des Windstromes wirkungslos abgelenkt wird. Die Windflügel werden nicht mit der vollen Wucht der augenblicklichen Windkraft getroffen. Darüberhinaus ist bei der erfindungsgemäßen Anordnung ein neuer Windflügel bereits teilweise im Wind, wenn der andere aus dem Wind heraustritt. Und zwar tritt bei optimaler Gestaltung der Windflügel in dem Wirkungsmaß aus dem Wind heraus, wie der andere Windflügel in den Wind hineintritt. Dadurch ist ein ruhiger Rotorlauf gewährleistet, und gleichzeitig das Pendeln des Lagerbockes bei Zwillingsbetrieb dieser Rotoren vermieden. always a bit inclined, so that part of the wind current is deflected ineffectively. The wind blades will be not hit with the full force of the current wind force. In addition, is in the invention Arrangement of a new wind blade already partly in the wind when the other one emerges from the wind. In fact, if the design of the wind blade is optimal, it emerges from the wind to the extent that it is how the other wing of the wind enters the wind. This ensures that the rotor runs smoothly, and at the same time the swinging of the bearing block with twin operation of these rotors is avoided.
In v/eiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die an der Drehachse des Rotors angeordneten Windflügel als ein Formteil hergestellt.In a further embodiment of the invention it is proposed that the wind blades arranged on the axis of rotation of the rotor be manufactured as a molded part.
Um die Leistung des Windkraftwerkes dem jeweiligen Bedarf anpassen zu können, wird in einer Weiterbildung der Erfindung vorgeschlagen, daß die Formteile so ausgebildet sind, daß sie aufeinandersetzbar sind. Das erleichtert außerdem den Transport, besonders bei größeren Rotoren, zum Bestimmungsort. Die Formteile werden einzeln zum Bestimmungsort transportiert und erst dort zur ausgelegten Größe zusammengesetzt.In order to be able to adapt the output of the wind power plant to the respective requirements, a further training course The invention proposed that the molded parts are designed so that they can be placed one on top of the other. This also makes transport easier, especially with larger rotors, to the destination. The molded parts are transported individually to the destination and only then assembled to the designed size.

Zweckmäßigerweise werden die Formteile aus Kunststoff hergestellt.The molded parts are expediently made from plastic.
Die Erfindung wird anhand des gezeichneten Ausführungsbeispiels erläutert. The invention is explained with reference to the illustrated embodiment.
In der Zeichnung sind zwei der erfindungsgemäßen Rotoren 1, im Zwillingsbetrieb arbeitend, auf einem schwenkbar um den Turm 2 gelagerten Lagerbock 3 angeordnet. Jeder Rotor 1 besteht aus einer Drehachse 4 mit den an dieser angeordneten beiden Windflügeln 5 und 6. Die beiden Windflügel 5 und 6 sind aus einem Formteil 7 hergestellt. Durch die Anzahl der Formteile 7, die sich aufeinandersetzen lassen, läßt sich die Größe der Rotoren, und damit die Leistung des Windkraftwerkes bestimmen. Um einen Synchronlauf bei Verwendung der Rotoren 1 im Zwillingsbetrieb zu gewährleisten, sind diese über ein mechanisches Getriebe 8 miteinander gekuppelt.In the drawing, two of the rotors 1 according to the invention, working in twin operation, are arranged on a bearing block 3 pivotably mounted about the tower 2. Each rotor 1 consists of an axis of rotation 4 with the two wind blades 5 and 6 arranged thereon. The two wind blades 5 and 6 are made from a molded part 7. The size of the rotors, and thus the performance of the wind power station, can be determined by the number of molded parts 7 that can be placed one on top of the other. In order to ensure synchronous operation when the rotors 1 are used in twin operation, they are coupled to one another via a mechanical gear 8.
Die Windflügel 5 und 6 der Rotoren 1 sind um die Drehachse 4 wendelförmig verdreht. Um die gewünschte Verwendelung der Windflügel 5 und 6 zu erreichen, wird in Abhängigkeit von der Anzahl der aufeinander zu setzenden Formteile 7, bereits jedes Formteil 7 entsprechend verwendet .The wind blades 5 and 6 of the rotors 1 are twisted in a helical manner about the axis of rotation 4. In order to achieve the desired use of the wind blades 5 and 6, depending on the number of molded parts 7 to be placed on top of one another, each molded part 7 is already used accordingly.

Bei einem Rotor 1, bestehend aus vier Formteilen 7 und einer Gesamtverwendelung von 9o z.B. beträgt die Verwendelung eines Formteils 7 22,5 . In the case of a rotor 1 consisting of four molded parts 7 and a total usage of 90, for example, the usage of a molded part 7 is 22.5.
Durch die Verv/endelung wird in jeder Stellung des Rotors 1 nur ein Teil der einzelnen Windflügel 5 und vom Wind beaufschlagt. Durch diese kontinuierliche Aufnahme der Windkraft durch Teile der Windflügel 5 und 6 während der Rotordrehung wird das ruckweise Laufen der Rotoren 1 durch das bei den bekannten Rotoren übliche Wechselspiel der vollen Windkraftaufnahme zu einer minimalen Aufnahme vermieden.Due to the Verv / Endelung in each position of the rotor 1 only a part of the individual wind blades 5 and acted on by the wind. As a result of this continuous absorption of the wind power by parts of the wind blades 5 and 6 during the rotor rotation, the jerky running of the rotors 1 is caused by that in the known rotors the usual interplay between full wind power absorption and minimal absorption is avoided.
