Abstract

The regulator for a wind motor has the variable blade pitch controlled by a centrifugal force governor. These have sprung flyweights which are independent of the vanes, and the regulator is mounted in the hub of the rotor. The flyweights, when actuated by centrifugal force push a slide sleeve along the rotor axis against a spring. The longitudinal movement is changed to rotory movement of the vane shaft via bell cranks. The pitch charge is stopped at a given angle by an abutment sleeve.

Description

REGULATEUR POUR HELICE RECEPTRICE A VENT A PAS VARIABLE
L'originalité de cette invention réside dans le fait que
le pas variable de l'hélice et commandé par un régulateur cen
trifuge à ressort et masselottes complètement indépendant des pa
les de l'hélice, bien que celui-ci soit logé dans le moyeu de cette
hélice, les pales étant commandées par l'intermédiaire de biellettes
montées sur des roulements à billes étanches, ainsi que toutes les artnculations. VARIABLE STEP WIND RECEIVER REGULATOR
The originality of this invention lies in the fact that
the variable propeller pitch and controlled by a cen regulator
trifuge with spring and weights completely independent of the pa
the propeller, although it is housed in the hub of this
propeller, the blades being controlled by means of rods
mounted on sealed ball bearings, as well as all joints.

Le flasque (2) qui sert de support aux piliers (4) des pa-
les (5) est solidaire de l'arbre (1) du régulateur.The flange (2) which supports the pillars (4) of the
the (5) is integral with the shaft (1) of the regulator.

Sur ce même flasque, viennent se fixer les paliers (20) de
supports de masselottes (3) reliés par l'intermédiaire de biellettes
(14) avec le coulisseau (6) maintenu en position de démarrage à
l'arrêt de l'hélice par le r@ss@t (7).On the same flange, the bearings (20) of the
weights supports (3) connected by means of links
(14) with the slide (6) held in the start position at
stopping the propeller by r @ ss @ t (7).

Sur ce coulisseau (6) est reprise une biellette (t5) dont
l'entre extrémité vient.se fixer par un axe à l'arbre de pale qui .On this slide (6) is taken up a rod (t5) whose
the between end comes to be fixed by an axis to the blade shaft which.

se termine par une manivelle (16).  ends with a crank (16).

Dès que l'hélice commence à tourner, la force centrifuge
cherche à écarter les masselottes (13) de l'arbre de régulateur (1)
ce qui a pour effet, par l'intermédiaire du support (3) et de la
biellette (14) de pousser ie coulisseau (6). et de comprimer le
ressort (?).As soon as the propeller starts to spin, the centrifugal force
seeks to separate the weights (13) from the regulator shaft (1)
which has the effect, via the support (3) and the
rod (14) to push the slide (6). and compress the
spring (?).

le coulisseau (6) tire alors sur la biellette (15) qui,
par le manivelle (16) transforme le mouvenent longitudinal en mou
vement rotatif de l'arbre (4 A) support de pale (5) changeant le
pas de la pale (5).the slide (6) then pulls on the link (15) which,
by the crank (16) transforms the longitudinal movement into slack
rotary shaft (4 A) blade support (5) changing the
not the blade (5).

Quand la vitesse nominale est atteinte, le coulisseau (6)
est alors en butée sur le coulisseau (8) réglant définitivement le
pas nominal de l'hélice.When the nominal speed is reached, the slide (6)
is then in abutment on the slide (8) definitively regulating the
nominal pitch of the propeller.

Si la vitesse augmente, les masselottes (13) du régulateur
s'écartent un peu plus, faisant glisser les coulisseaux (6) et (8)
comprimant le ressort (10), le pas devenant alors négatif, obli
8Qant l'héli@c@ à ralentir, le ressort (10) ramenant @e coulisseau
(E) à sa butee (2t) nominale et les pales (5) à leur ras nominal.If the speed increases, the governor weights (13)
move a little further apart, sliding the sliders (6) and (8)
compressing the spring (10), the pitch then becoming negative, oblivion
8As for the heli @ c @ to slow down, the spring (10) bringing back the slide
(E) at its nominal stop (2t) and the blades (5) at their nominal flush.

Ceci constitue le dispositif de ralentissement du régulatueur.  This constitutes the device for slowing down the regulator.

Par ailleurs, le coulisseau (8) est réglable en longueur par la butée de ressort (9) qui est vissée sur le coulisseau (8) ce qui permet de faire un réglage optimum rominal du pas de l'hélice et de le bloquer définitivement par le contre-écrou (19).  Furthermore, the slider (8) is adjustable in length by the spring stop (9) which is screwed onto the slider (8) which makes it possible to make an optimum Roman adjustment of the pitch of the propeller and to block it definitively by the lock nut (19).

Claims (1)

REVENDICATIONS I - Le régulateur pour hélice réceptice avare, caractérisé en ce que le pas variable de l'hélice est réglé par un régulateur à force centrifuge, à ressorts et masselottes complètement indépendants des pale de l'hélice; ce régulateur est logé dans le moyeu de cette hélice. I - The regulator for a stingy propeller, characterized in that the variable pitch of the propeller is adjusted by a centrifugal force regulator, with springs and flyweights completely independent of the propeller blades; this regulator is housed in the hub of this propeller. II - Régulateur selon les revendications I, caractérisé ence que les masselottes qui subissent la force centrifuge, repoussent le coulisseau (6) sur l'axe de l'hélice en comprimant le ressort (7). II - Regulator according to claims I, characterized in that the weights which undergo the centrifugal force, push the slide (6) on the axis of the propeller by compressing the spring (7). Le mouvement longitudinal est transformé en mouvement rotatif de l'axe de la pale par la transmission de biellette (t5) et (16). Ce mouvement amène le pas de l'hélice à la position nominale lorsque le coulisseau (6) butera sur le coulisseau (8).The longitudinal movement is transformed into rotary movement of the axis of the blade by the link transmission (t5) and (16). This movement brings the pitch of the propeller to the nominal position when the slide (6) will land on the slide (8). III - Régulateur selon l'une des revendications I et II, carac devisé par le dispositif de ralentissement suivant. Si la vitesse de rotation de l'hélice aulmente, les coulisseaux (6) et (8) vont se déplacer et comprimer le ressort (10). Ce mouvement va provoquer la rotation des pales de l'hélice, dont le pas va devenir négatif. De ce fail la vitesse diminua et ltensemble va revenir à la position nominale.  III - Regulator according to one of claims I and II, charac devised by the following deceleration device. If the speed of rotation of the propeller increases, the slides (6) and (8) will move and compress the spring (10). This movement will cause the propeller blades to rotate, the pitch of which will become negative. As a result, the speed decreased and the assembly returned to the nominal position.
