Abstract[English]
An SMA actuator assembly (1) comprising: a support structure (10), a rotating part (40) arranged to rotate about a rotation axis (R); a movable part (20) arranged to move in a plane perpendicular to the rotation axis and along a boundary (45) of the rotating part, wherein one of the rotating part and the movable part surrounds the other of the rotating part and the movable part in the plane perpendicular to the rotation axis; and three or more SMA wires (30) arranged, on contraction, to move the movable part along the boundary of the rotating part, such that contact between the movable part and the rotating part drives continuous rotation of the rotating part about the rotation axis, wherein the arrangement of the three or more SMA wires is capable of applying a torque to the movable part.[French]
L'invention concerne un ensemble actionneur SMA (1) comprenant : une structure de support (10), une partie rotative (40) agencée pour tourner autour d'un axe de rotation (R) ; une partie mobile (20) agencée pour se déplacer dans un plan perpendiculaire à l'axe de rotation et le long d'une limite (45) de la partie rotative, l'une de la partie rotative et de la partie mobile entourant l'autre de la partie rotative et de la partie mobile dans le plan perpendiculaire à l'axe de rotation ; et au moins trois fils en alliage à mémoire de forme (SMA) (30) disposés, lors de la contraction, pour déplacer la partie mobile le long de la limite de la partie rotative, de telle sorte qu'un contact entre la partie mobile et la partie rotative entraîne une rotation continue de la partie rotative autour de l'axe de rotation, l'agencement des trois fils SMA ou plus étant capable d'appliquer un couple à la partie mobile.
