MOTOR-DRIVEN ACTUATOR AND DISPLACEABLE BARRIER PROVIDED WITH SUCH ACTUATOR, PARTICULARLY SUITABLE FOR AUXILIARY OR EMERGENCY DRIVES
The motorized drive (5) according to the invention is particularly suitable for auxiliary or emergency drives and is configured to open or close a wing (3) of a barrier such as a door. The motorized drive (5) comprises a motor (7) and a reduction unit (9) through which the motor (7) can open or close the wing (3), an auxiliary motor (7') comprising a helical spring (19) which is able to absorb mechanical energy during the opening of the wing (3) and release it during the closing of the same, a reduction unit (9') connecting the auxiliary motor (7') to the wing (3). A first (11,11') and a second toothed profile (13,13') realize a gear with a variable transmission ratio. The first (11,11') and/or the second toothed profile (13,13') form at least one toothing having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.
