Abstract

A wind generator has a first propeller (3) for the rotor of a generator whose stator is also rotated, this being done by a second propeller (4) on the opposite side of the generator. It spins the stator in the reverse direction to that of the rotor. A hydro-generator has the same principle of operation, except that there is a contra-rotating stator turbine wheel on the same side as the rotor turbine wheel as well as a stator turbine wheel on the far side. The rotor and stator shaft ends are joined to their respective turbine wheels inside housings. The rotor runs in stator bearings at its non-turbine wheel end and the stator runs in rotor bearings at the other end.

Description

Die Erfindung bezieht sich auf einen Windgenerator gemäß Oberbegriff des Anspruchs 1.The invention relates to a wind generator according to Preamble of claim 1.

Bei bekannten Windgeneratoren dieser Art ist der Stator gera­ tefest. Ein zweiter Propeller ist nicht vorhanden.In known wind generators of this type, the stator is straight tefest. There is no second propeller.

Der Erfindung liegt die Aufgabe zugrunde, einen solchen Gene­ rator derart auszubilden, daß er mehr Energie als die bekann­ ten liefert.The invention has for its object such a gene rator so that he got more energy than that ten supplies.

Diese Aufgabe wird, wie im Kennzeichen des Anspruchs 1 ange­ geben ist, gelöst.This task is as in the characterizing part of claim 1 giving is solved.

Auf diese Weise wird erreicht, daß sich Stator und Rotor mit größerer Relativgeschwindigkeit (bei Normalausführung mit doppelter Relativgeschwindigkeit), verglichen mit den bekann­ ten Fällen, zueinander drehen, was eine entsprechende Vergrö­ ßerung der Energieausbeute mit sich bringt.In this way it is achieved that the stator and the rotor higher relative speed (with normal version with double relative speed) compared to the known ten cases, rotate towards each other, which is a corresponding magnification increase in energy yield.

Die Erfindung bezieht sich ferner auf einen Turbinengenerator gemäß Oberbegriff des Anspruchs 2. Für diesen gilt praktisch das gleiche wie für den Windgenerator. Der Turbinengenerator unterscheidet sich jedoch vom Windgenerator dadurch, daß ein­ erseits das zweite Turbinenrad auf derselben Seite des Gene­ rators wie das erste Turbinenrad und andererseits auf der dem ersten Turbinenrad gegenüberliegenden Seite des Generators angeordnet sein kann (beim Windgenerator gäbe die Lösung: zweiter Propeller auf derselben Seite des Generators angeord­ net wie der erste Propeller, keinen Sinn, weil zwei dicht nebeneinander angeordnete, entgegengesetzt zueinander laufende Propeller sich gegenseitig negativ beeinflussen würden).The invention further relates to a turbine generator according to the preamble of claim 2. For this applies practically  the same as for the wind generator. The turbine generator differs from the wind generator in that a the second turbine wheel on the same side of the gene rators like the first turbine wheel and on the other hand on the first turbine wheel opposite side of the generator can be arranged (with the wind generator the solution would be: second propeller arranged on the same side of the generator net like the first propeller, no sense, because two tight juxtaposed, opposed to each other Propellers would negatively affect each other).

Es ist zweckmäßig, wenn der vordere Propeller mit dem Teil (Rotor oder Stator) des Generators, das die größere Masse hat, insbesondere mit dem drahtbewickelten Rotor verbunden ist. (Wegen der Turbulenzen, denen der hintere Propeller aus­ gesetzt ist, setzt dieser weniger Energie um als der vordere.)It is useful if the front propeller with the part (Rotor or stator) of the generator, which is the larger mass has, in particular connected to the wire-wound rotor is. (Because of the turbulence that the rear propeller is from is set, it uses less energy than the front.)

Fig. 5 einen Schnitt nach der Linie V-V der Fig. 3. Fig. 5 shows a section according to the line VV of FIG. 3.

Der in Fig. 1 veranschaulichte Windgenerator besteht aus ei­ nem Ständer 1, einem an dessen oberen Ende angeordneten Stromgenerator 2 und zwei entgegengesetzt zueinander rotie­ renden Propellern 3 und 4. Der die Propeller antreibende Wind kommt von rechts, siehe die Pfeile 5. The wind generator illustrated in FIG. 1 consists of a stand 1 , a current generator 2 arranged at its upper end and two propellers 3 and 4 rotating in opposite directions to one another. The wind driving the propellers comes from the right, see arrows 5 .

Fig. 2 zeigt den zwischen den beiden Propellern angeordneten Generator 2. Dieser besteht aus einem Gehäuse 6. In diesem ist über Lager 7 eine Welle 8 gelagert, auf der ein Rotor 9 fest sitzt. Die Welle 8 bildet ein erstes Wellenende 10, das mit dem ersten Propeller 3 verbunden ist. Ein zweites Wellen­ ende 11 ist über ein Lager 12 in dem Gehäuse 6 gelagert und mit dem zweiten Propeller 4 verbunden. Am Ende dieses zweiten Wellenendes 11 sitzt fest mit diesem verbunden ein Stator 13. Auf der dem Wellenende 11 abgewandten Seite des Stators ist dieser über ein Lager 14 auf der Welle 8 gelagert. Letztere ist ihrerseits auf der rechten Seite der Fig. 2 über ein La­ ger 15 an dem Stator 13 gelagert. Die Relativbewegungen zwi­ schen Stator und Rotor, die zur Stromerzeugung führen, spie­ len sich diesseits und jenseits des Spaltes 16 ab. Fig. 2 shows the disposed between the two propellers generator 2. This consists of a housing 6 . In this, a shaft 8 is mounted on the bearing 7 , on which a rotor 9 is seated. The shaft 8 forms a first shaft end 10 , which is connected to the first propeller 3 . A second shaft end 11 is supported by a bearing 12 in the housing 6 and connected to the second propeller 4 . At the end of this second shaft end 11 , a stator 13 is firmly connected to it. On the side of the stator facing away from the shaft end 11, the stator is supported on the shaft 8 via a bearing 14 . The latter in turn is mounted on the right side of FIG. 2 via a bearing 15 on the stator 13 . The relative movements between the stator and the rotor, which lead to the generation of electricity, play on both sides of the gap 16 .

Der Generator 2 weist einen Hilfsrotor 17 und einen Hilfssta­ tor 18 auf, die ebenfalls der Stromerzeugung dienen, wobei in diesem Falle der Rotor 17 gehäusefest ist, so daß die Rela­ tivgeschwindigkeit zwischen den Teilen 17 und 18 halb so groß ist wie zwischen den Teilen 13 und 9.The generator 2 has an auxiliary rotor 17 and an auxiliary gate 18 , which also serve to generate electricity, in which case the rotor 17 is fixed to the housing, so that the relative speed between the parts 17 and 18 is half as large as between the parts 13 and 9 .

Die Fig. 3 bis 5 zeigen einen Turbinengenerator der erfin­ dungsgemäßen Art. Mit 102 ist der Generator bezeichnet, der im Prinzip genauso ausgebildet ist wie der Generator 2. Auf der linken Seite des Generators 102 befindet sich ein Turbi­ nenrad 103, auf der rechten Seite des Generators 102 befindet sich ein Turbinenrad 104. Beide Räder laufen entgegengesetzt zueinander, was sich durch die Ausbildungen der Schächte, durch die das Wasser läuft, problemlos durchführen läßt (siehe die Fig. 4 und 5). Die beiden Turbinenräder 103 und 104 sitzen auf Wellenenden, die mit dem Rotor bzw. Stator des Generators 102 verbunden sind. FIGS. 3 to 5 show a turbine generator of the kind OF INVENTION to the invention. With the generator 102 is referred to, which is designed in principle the same as the generator 2. On the left side of the generator 102 there is a turbine wheel 103 , on the right side of the generator 102 there is a turbine wheel 104 . Both wheels run counter to each other, which can be easily carried out by the formation of the shafts through which the water runs (see FIGS. 4 and 5). The two turbine wheels 103 and 104 sit on shaft ends, which are connected to the rotor or stator of the generator 102 .
