Abstract
Drive mechanism for roller shutters, which is essentially characterized by two hollow concentric drums, one fitted inside the other, one of which is fixed and the other rotating, both being mounted on a common rotating shaft which, in turn, it constitutes the winding drum of the shutter, the rotating drum having its internal face integral with a gear wheel on which engages a planetary pinion, mounted rotating loco around an axis fixed to an arm that is integral with the rotating shaft indicated, and whose planetary pinion engages at the same time with a toothing provided on the internal periphery of the fixed drum, on which it moves during its translational movement.
