Abstract:
A linear electro-mechanical actuator, includes a containment structure (2), one or two pushers facing each other (7), a nut (5) rotatable about an axis (X) driven by a driving force, a screw shaft (6) inserted in the nut (5), connected to the pushers and interconnected with the nut (5) via a helical recirculating ball coupling (5a, 6a), and an anti-rotation mechanism (8) acting on the screw shaft (6) to prevent the screw shaft (6) from rotating about the axis (X). The anti-rotation mechanism (8) includes a pair of fixed guide bars (9), coupled in a sliding fashion with the screw shaft (6) and extending along a direction parallel to the axis (X) and spaced from the axis (X).
