Title (EN) SEMI-ROTARY HYDRAULIC ACTUATOR
(FR) ACTIONNEUR HYDRAULIQUE SEMI-ROTATIF
Abstract:
(EN) An actuator (10) for rotating a shaft (11) includes a housing (12) having a first port (27), a second port (28) and a drive track (26). A first drive means (29) is coupled to the first port (27) and a second drive means (30) is coupled to the second port (28). An array of balls (33) which is spaced apart by spacers (34) define a drive train extending from one drive means (29) to the second drive means (30) via the drive track (26). A drive pin (14) which extends outwardly from the shaft (11) is connected to the drive train and the first and second drive means (29 and 30) are driven so that the drive train will rotate the drive pin (14) and hence the shaft (11).
(FR) L'invention porte sur un actionneur (10) permettant de faire tourner un arbre (11) et comprenant un corps (12) constitué d'un premier (27) et d'un second (28) port et d'une bande de transmission (26). Un premier dispositif d'entraînement (29) est couplé au premier port (27) et un second dispositif d'entraînement (30) au second port (28). Un ensemble de billes (33) espacées par des espaceurs (34) forment un mécanisme de transmission passant par la bande de transmission (26) et allant du premier (29) au second (30) dispositif d'entraînement. Un axe d'entraînement (14) faisant saillie de l'arbre (11) vers l'extérieur est raccordé au mécanisme de transmission, les premier (29) et second (30) dispositifs d'entraînement étant entraînés de sorte que le mécanisme de transmission mette en rotation l'axe d'entraînement (14) et par conséquent l'arbre (11).
