IMPROVED GEARED MOTOR FOR ROLLING SHUTTERS
A geared motor (100) for rolling shutters, comprises: an electrical motor (1) provided with a drive shaft (1a) that slides axially; a reducer (2) coupled to the drive shaft (1a) and to the winding shaft of a rolling shutter, uncoupling means (7) of the electrical motor (1) from the reducer (2); a non-return device (D) connected to the drive shaft (1a) to make the transmission of motion from the electrical motor (1) to the reducer irreversible, an emergency device (E) to uncouple the drive shaft (1a) from the reducer (2) when the uncoupling means (7) are operated; the emergency device (E) comprises: a toothed cover (4) slidingly integral with the drive shaft (1a) and rotationally integral with the non-return device (D) and with the reducer (2); and a helical compression spring (5) to push the toothed cover (4) in engagement with the reducer (2).
