MOTOR-DRIVEN ACTUATOR AND DISPLACEABLE BARRIER PROVIDED WITH SUCH ACTUATOR
The motorized drive (5) according to the invention is configured to open and/or close a wing (3) of a barrier such as a door, main door, gate or swing shutter, a wall or sliding partition or other sliding wing. The motorized drive (5) comprises a motor (7) and a first reduction unit (9) through which the motor (7) can open or close the wing (3). The reduction unit (9) comprises a first (11) and a second toothed profile (13) engaging together, thus realizing a gear with a variable transmission ratio depending on the angular and/or linear position of at least one of the two toothed profiles. At least one of the first (11) and of the second toothed profile (13) forms at least one toothed section having a pitch profile which is substantially non-circular or not formed by a simple arc of a circle or a straight line.
