Title
(EN) ELECTROMECHANICAL ACTUATOR FOR USE UNDER WATER
(FR) ACTIONNEUR ÉLECTROMÉCANIQUE POUR UNE UTILISATION SOUS L'EAU
Abstract
(EN) Electromechanical actuator (1 ) with a through-going centre passage (8) for use under water, wherein the motor (18) and transmission elements (28, 32, 36 and 38) are arranged in parallel with and are via dog elements (40) mechanically coupled to the axially displaceable elements (14, 44) through a sealing partition (16). A hydraulic axially displaceable piston ring (56) facilitates secondary release of locking segments (10) in a coupling device.
(FR) L'invention concerne un actionneur électromécanique (1) ayant un passage central traversant (8) pour une utilisation sous l'eau, le moteur (18) et des éléments de transmission (28, 32, 36 et 38) étant agencés en parallèle à et le sont via des éléments à crabots (40) mécaniquement couplés aux éléments aptes à être axialement déplacés (14, 44) par l'intermédiaire d'une cloison d'étanchéité (16). Un anneau de piston hydraulique apte à être axialement déplacé (56) facilite la libération secondaire de segments de verrouillage (10) dans un dispositif de couplage.
