Abstract

The wind power generator has a rotor (1) with a main transmission shaft (2) mounted on open bearing rollers (21). The rollers can have a non-cylindrical array, such as a barrel shape and the main shaft can have a correspondingly shaped race surface (22). The surfaces of the rollers can be coated in a sound reducing medium (27). The shaft can be connected to a flywheel with a gear pair (24,25).

Beschreibung der Erfindung:Description of the invention:

An der Hauptwelle (2) ist die Rotornabe (1) befestigt, deren Rotor von einem strömenden Medium (z.B. Wind) angetrieben wird. Die Hauptwelle (2) ist im Hauptlager (3) drehbar gelagert. Das Hauptlager nach 1 besteht aus zwei einzelnen Rahmen mit jeweils drei Rollen (21), von denen jeweils zwei Rollen (21) die Hauptwelle (2) von unten stützen und jeweils eine Rolle (21) oben angeordnet ist und eventuellen Kippmomenten aus der Rotornabe (1) entgegenwirkt. Aus 2 ist ersichtlich, dass die Rollen (21) des ersten Hauptlagers (3) tonnenförmig ausgebildet ist und in der entsprechende Negativform der Laufbahn (22) der Hauptwelle (2) läuft. Da die Rollen (21) des zweiten Hauptlagers zylindrisch geformt auf der Hauptwelle (2) laufen, ergibt sich die traditionell bekannte Konfiguration von Fest- und Loslager. Die Rollen (21) oder die Laufbahn (22) können mit einer Schalldämmung (27) zur Körperschallentkoppelung belegt werden (3 und 4).At the main shaft ( 2 ) is the rotor hub ( 1 ), whose rotor is driven by a flowing medium (eg wind). The main shaft ( 2 ) is in the main warehouse ( 3 ) rotatably mounted. The main camp after 1 consists of two individual frames with three rollers each ( 21 ), of which two roles ( 21 ) the main shaft ( 2 ) from below and one roll each ( 21 ) is arranged above and any tilting moments from the rotor hub ( 1 ) counteracts. Out 2 it can be seen that the roles ( 21 ) of the first main warehouse ( 3 ) is barrel-shaped and in the corresponding negative shape of the track ( 22 ) of the main shaft ( 2 ) running. Because the roles ( 21 ) of the second main bearing cylindrically shaped on the main shaft ( 2 ), results in the traditionally known configuration of fixed and floating bearings. The roles ( 21 ) or the career path ( 22 ) can with a sound insulation ( 27 ) for structure-borne noise decoupling ( 3 and 4 ).

An der Hauptwelle (2) ist als erste Übersetzungsstufe ein offenes Vorgelege (4) befestigt, dessen Triebstock (23) das Triebstockritzel (24) antreibt.At the main shaft ( 2 ) is the first translation stage an open submission ( 4 ) whose driving stick ( 23 ) the drive pinion ( 24 ) drives.

Durch das offene Vorgelege (4) und die Haupfwelle (2) ist das Leitungsrohr (26) zur Rotornabe (1) geführt.Through the open countershaft ( 4 ) and the main wave ( 2 ) is the conduit ( 26 ) to the rotor hub ( 1 ) guided.

Das Triebstockritzel (24) sitzt auf einer gemeinsamen Welle mit dem Planetenrad (25). Damit bildet diese Einheit die Funktion eines Stufenplanetengetriebes nach. Vom Planetengetriebe (5) aus wird das Drehmoment über eine Kupplung (6) auf ein Kegelradgetriebe (8) übertragen. Das Kegelradgetriebe (8) nach 1 hat eine seitlich herausgezogene Kegelritzelwelle, auf die eine Bremsscheibe (9) befestigt ist. Die erste Scheibenbremse (7) wirkt auf diese Bremsscheibe (9).The driving stick pinion ( 24 ) sits on a common shaft with the planetary gear ( 25 ). Thus, this unit simulates the function of a stepped planetary gear. From the planetary gear ( 5 ) the torque is transmitted via a clutch ( 6 ) on a bevel gear ( 8th ) transfer. The bevel gear ( 8th ) to 1 has a laterally extracted bevel pinion shaft, on which a brake disc ( 9 ) is attached. The first disc brake ( 7 ) acts on this brake disc ( 9 ).

An der nach unten herausgezogenen Kegelritzelwelle des Kegelradgetriebes (8) ist eine, in ihrer Längsachse verschiebbare, Gelenkwelle (10) befestigt, deren anderes Ende mit der Welle des Generators (11) verbunden ist.At the downwardly drawn bevel pinion shaft of the bevel gear ( 8th ) is a, in its longitudinal axis displaceable, propeller shaft ( 10 ) whose other end is connected to the shaft of the generator ( 11 ) connected is.

Hauptlager (3), Planetengetriebe (5), Scheibenbremse (7) und Kegelradgetriebe (8) sind auf einem Maschinenträger (14) montiert, der mittels Trägerlager (15) drehbar gelagert ist und vom Dämpfer (13) elastisch in seiner Betriebsposition gehalten wird. Dämpfer (13) und Trägerlager (15) sind am Drehkranz der Gondel (12) befestigt. Durch Windböen kommt es zu Nickbewegungen des Maschinenträgers (13) und der darauf befestigten Komponenten. Die Gelenkwelle (10) gleicht die Wege- und Winkeldifferenzen zwischen der variablen Position der Ausgangswelle des Kegelradgetriebes (8) und der festen Position der Eingangswelle des Generators (11) aus.Main warehouse ( 3 ), Planetary gear ( 5 ), Disc brake ( 7 ) and bevel gear ( 8th ) are on a machine carrier ( 14 ) mounted by means of a carrier bearing ( 15 ) is rotatably mounted and the damper ( 13 ) is held elastically in its operating position. Damper ( 13 ) and support bearings ( 15 ) are on the turntable of the gondola ( 12 ) attached. Wind gusts cause pitching movements of the machine carrier ( 13 ) and the components mounted thereon. The propeller shaft ( 10 ) equals the path and angle differences between the variable position of the output shaft of the bevel gear ( 8th ) and the fixed position of the input shaft of the generator ( 11 ) out.

Der Generator (11) ist über das elastische, den Körperschall entkoppelnde Generatorlager (20) senkrecht im Turm (19) befestigt. Der Azimutantrieb (18) ist ebenfalls im Turm (19) positioniert.The generator ( 11 ) is via the elastic, the structure-borne sound decoupling generator bearing ( 20 ) vertically in the tower ( 19 ) attached. The azimuth drive ( 18 ) is also in the tower ( 19 ).

Das Ritzel des Azimutantriebs (18) treibt über den Zahnkranz (17), der über Distanzblech (29) und Schraube (28) mit dem Drehkranz der Gondel (12) verbunden ist, die Gondel (12) an. Der Drehkranz der Gondel (12) ist mittels Azimutlager (16) auf dem Turm (19) gelagert. In 5 wird diese Drehverbindung während zweier Zustände dargestellt. Bei Transport und Montage sind die Distanzbleche (29) zwischen Zahnkranz (17) und Drehkranz der Gondel (12) entfernt und es erfolgt über die Schrauben (28) eine kraftschlüssige Verbindung zwischen Turm (19), Azimutlager (16) und Gondel (12). Während des Betriebes sind die Distanzbleche (29) montiert, so dass die Gondel (12) frei in den Wind gedreht werden kann.The pinion of the azimuth drive ( 18 ) drives over the sprocket ( 17 ), which via spacer plate ( 29 ) and screw ( 28 ) with the turntable of the gondola ( 12 ), the gondola ( 12 ) at. The turntable of the gondola ( 12 ) is by means of azimuth bearing ( 16 ) on the tower ( 19 ) stored. In 5 This rotary joint is shown during two states. During transport and installation, the spacer plates ( 29 ) between sprocket ( 17 ) and turntable of the gondola ( 12 ) and it is done via the screws ( 28 ) a non-positive connection between tower ( 19 ), Azimuth bearings ( 16 ) and gondola ( 12 ). During operation, the spacers ( 29 ), so that the gondola ( 12 ) can be turned freely in the wind.
