Description
MOTEUR EOLIEN, EN PARTICULIER A GRANDE VITESSE.
L'invention concerne un moteur éolien, en particulier à grande vitesse. Lors du fonctionnement de ces moteurs,il est apparu
<EMI ID=1.1>
particulier lors des rafales., la roue éolienne cherche à se placer dans la nouvelle direction du vent par à-coups. Il en résulte des moments de torsion, qui mettent l'ensemble de l'installation en danger.
' Ces moments de torsion résultent du produit du moment d'inertie de la roue éolienne, de la vitesse angulaire de la roue
elle-même,, et de la vitesse angulaire à laquelle la roue éolienne se place dans le ,vent. Du fait de ces moments de torsion, qui
sont très considérables, l'arbre de la roue éolienne est, suivant
le sens du moment de torsion, soumis à une pression vers le haut
ou vers le bas et, de ce fait, à des efforts de flexion se produisant brusquement, dangereux et alternant constamment, qui peuvent facilement en produire la rupture. Mais le pylône est, lui
aussi, soumis de ce fait à de dangereux efforts.alternants.
Ce grave inconvénient est évité selon l'invention du fait
que l'on prévoit un dispositif destiné à l'amortissement des
déviations ou écarts latéraux de la roue éolienne lors de son
orientation suivant une nouvelle direction. du vent lors de rafales survenant brusquement et qui ne frappent pas la roue éolienne perpendiculairement, dispositif dans lequel l'amortissement
croît proportionnellement au carré de la vitesse angulaire du
changement de direction. La vitesse angulaire lors de l'orienta-

Cet amortissement est assuré par deux ou plusieurs pompes à huiles mues par la roue éolienne lors de ses changements de direction, et qui n'opposent pas de résistance à la roue éolienne lors d'un changement de di-

tement les pompes à huile. Les pompes sont raccordées de telle sorte qu'aussi bien les conduites de refoulement de toutes les pompes que les conduites d'aspiration de toutes les pompes sont reliées entre elles. Une conduite présentant un étranglement relie les conduites d'aspiration aux conduites de refoulement.
Un exemple de réalisation de l'invention est représenté sur les dessins ci-annexés.
La figure 1 est une vue de côté de la roue éolienne d'un moteur éolien à grande vitesse avec la partie supérieure du pyl8ne. La figure 2 est une coupe verticale axiale à travers le dispositif amortisseur, à plus grande échelle. La figure 3 est une représentation schématique de la disposition et du raccordement des différentes pompes.

Pour empêcher que de grands moments de torsion soient engendrés lors de l'orientation de.la roue dentée dans une nouvelle direction de vent, on amortit, suivant l'invention, la déviation de la roue éolienne, résultant des changements de direction.

mité inférieure de celui-ci, une grande roue dentée 7 qui, dans l'exemple de réalisation représenté, est en prise.:avec trois pignons 8, 9, 10. Ces pignons actionnent des pompes à huile à engrenage 11, 12 et 13. Chacune des pompes à huile à engrenage consiste en une roue dentée centrale 14, qui est entraînée par l'intermédiaire de l'un des pignons situé sur le même arbre et en deux roues dentées montées latéralement 15 et 16. Les pompes à huile sont à double effet. Les cotés d'aspiration et de refoulement des pompes dépendent du sens dans lequel le vent cherche à déplacer la roue éolienne.
Si la roue éolienne �est déviée dans le sens des aiguilles d'une montre, lorsqu'on regarde le moteur éolien d'au-dessus, les roues dentées 8, 9, 10 et par suite les roues de pompes 14'tournent aussi dans le sens des aiguilles d'une montre par rapport à la figure 3. De ce fait,les conduites 17, 18 deviennent des conduites d'aspiration,et les conduites 19, soldes
WIND MOTOR, ESPECIALLY AT HIGH SPEED.
The invention relates to a wind motor, in particular at high speed. During the operation of these engines, it appeared
<EMI ID = 1.1>
particularly during gusts., the wind wheel tries to position itself in the new direction of the wind in spurts. This results in torsional moments, which endanger the entire installation.
'These torsional moments result from the product of the moment of inertia of the wind wheel, the angular speed of the wheel
itself ,, and of the angular speed at which the wind wheel moves into the wind. Due to these torsional moments, which
are very considerable, the shaft of the wind wheel is, following
the direction of the torque when subjected to upward pressure
or downwards and, therefore, to sudden, dangerous and constantly alternating bending forces which can easily cause it to break. But the pylon is
also, subjected by this fact to dangerous alternating efforts.
This serious drawback is avoided according to the invention because
that a device is provided for the amortization of
deviations or lateral deviations of the wind wheel during its
orientation in a new direction. wind in sudden gusts which do not strike the wind wheel perpendicularly, device in which the damping
increases in proportion to the square of the angular speed of the
change of direction. The angular velocity during orienta-
<EMI ID = 2.1>
___________________.___.________._ cloud and torsional moments that still occur are reduced to a low amplitude, no longer endangering the wind motor. This damping is provided by two or more oil pumps driven by the wind wheel during its changes of direction, and which do not oppose resistance to the wind wheel during a change of direction.
<EMI ID = 3.1>
the oil pumps. The pumps are connected in such a way that both the pressure lines of all pumps and the suction lines of all pumps are interconnected. A pipe with a constriction connects the suction pipes to the discharge pipes.
An exemplary embodiment of the invention is shown in the accompanying drawings.
Figure 1 is a side view of the wind wheel of a high speed wind motor with the upper part of the pyl8ne. Figure 2 is an axial vertical section through the damper device, on a larger scale. FIG. 3 is a schematic representation of the arrangement and connection of the various pumps.
The horizontal working shaft is connected to the wind wheel
<EMI ID = 4.1>
wind wheel has the vertical pivot 3, which is journaled
<EMI ID = 5.1>
at the top of the pylon 6.
In order to prevent large torsional moments from being generated when orienting the toothed wheel in a new wind direction, the deviation of the wind wheel resulting from the changes in direction is damped according to the invention.
<EMI ID = 6.1>
lower end thereof, a large toothed wheel 7 which, in the illustrated embodiment, is engaged: with three pinions 8, 9, 10. These pinions actuate geared oil pumps 11, 12 and 13 Each of the gear oil pumps consists of a central toothed wheel 14, which is driven through one of the pinions on the same shaft and two side mounted toothed wheels 15 and 16. The oil pumps are double acting. The suction and discharge sides of the pumps depend on the direction in which the wind seeks to move the wind wheel.
If the wind wheel is deflected clockwise, when looking at the wind motor from above, the gear wheels 8, 9, 10 and hence the pump wheels 14 ' also rotate clockwise with respect to figure 3. As a result, the pipes 17, 18 become suction pipes, and the pipes 19, balances
