  • Linear electro-mechanical actuator
    Patent number: 9774227
    Abstract: A linear electro-mechanical actuator includes a containment structure (2), a nut (5) positioned in the containment structure (2), a screw shaft (6) inserted in the nut (5) and interconnected with the nut (5) via a helical recirculating ball coupling, and an anti-rotation mechanism (9) positioned inside the screw shaft (6) to prevent the screw shaft (6) from rotating about the axis (X). The anti-rotation mechanism (9) includes a guide unit (10) fixed cantilever-style to the containment structure (2) and connected to the screw shaft by a non-rotational coupling.
    Type: Grant
    Filed: November 12, 2013
    Date of Patent: September 26, 2017
    Assignee: UMBRA CUSCINETTI S.P.A.

  • Linear electro-mechanical actuator with built-in anti-rotation
    Patent number: 9371895
    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).
