Title
(EN) TORSIONAL VIBRATION DRIVE
(FR) ENTRAINEMENT A OSCILLATION DE ROTATION
Abstract
(EN)
A torsional vibration drive for a laser gyro comprises a hub, spokes and an outer rim, with piezoceramics arranged on the spokes. Bending elements provided at the junction of the spokes and rim ensure high flexibility for rotations of the rim around the axis of rotation of the drive.
(FR)
Entraînement à oscillation de rotation pour laser gyroscopique comportant un moyeu, des rayons et une jante extérieure, avec des piézocéramiques disposées sur les rayons. A la jonction des rayons et de la jante sont disposés des éléments de flexion qui assurent une grande flexibilité dans les rotations de la jante autour de l'axe de l'entraînement.
