Abstract
A linear electro-mechanical actuator includes a containment structure (), a nut () positioned in the containment structure (), a screw shaft () inserted in the nut () and interconnected with the nut () via a helical recirculating ball coupling, and an anti-rotation mechanism () positioned inside the screw shaft () to prevent the screw shaft () from rotating about the axis (X). The anti-rotation mechanism () includes a guide unit () fixed cantilever-style to the containment structure () and connected to the screw shaft by a non-rotational coupling.
