Title
(EN) LONGITUDINALLY DRIVEN SLOTTED CYLINDER TRANSDUCER
(FR) TRANSDUCTEUR CYLINDRIQUE A FENTES LONGITUDINALES
Abstract
(EN) A longitudinally driven slotted transducer (70) has a tubular member with an axial slot (72) extending from one end to die other end. A drive assembly (73) is disposed across the inner wall (75) of the tubular member and supported by journal bearing surfaces (78) extending from opposing sides of the inner wall to locate the drive assembly in a position offset from die longitudinal central axis (L) of the tubular member. The interface between the drive assembly and tubular member comprises a layer of solid lubricant material (79) mounted on the journal bearing type surfaces.
(FR) L'invention concerne un transducteur à fentes longitudinales. Ledit transducteur comprend un élément tubulaire présentant une fente axiale qui s'étend d'une extrémité à l'autre extrémité. Un ensemble d'excitation est disposé d'un côté à l'autre de la paroi intérieure de l'élément tubulaire et supporté par des surfaces de portée des tourillons s'étendant à partir des côtés opposés de la paroi intérieure afin de placer l'ensemble d'excitation dans une position décalée par rapport à l'axe central longitudinal de l'élément tubulaire. L'interface entre l'ensemble d'excitation et l'élément tubulaire comprend une couche de matériau lubrifiant solide monté sur les surfaces de type portée des tourillons.
