Patent

CA 2249740

The invention concerns a swivelling device comprising: a base member; a swivel shaft (6) which, in operation, can rotate about a swivel axis; a drive; and gearing. The swivelling device operates particularly reliably when the drive comprises at least one actuator (4, 5) operated by pressurized fluid. The invention provides a low-maintenance drive which has high torque and retaining forces, of the type required for satellite antennae, for example.

L'invention concerne un dispositif pivotant comprenant un corps de base, un arbre pivotant (6) pouvant tourner autour d'un pivot lorsque le dispositif est en marche, ainsi qu'un système d'entraînement et une transmission. Ce dispositif assure un fonctionnement particulièrement fiable lorsque le système d'entraînement comprend au moins un élément de réglage actionné par un fluide pressurisé. Cette invention permet d'obtenir des systèmes d'entraînement nécessitant un entretien minimal, avec des couples et des forces de retenue élevés, du type de ceux qui sont requis pour des antennes de satellite.
