An actuator includes a threaded spindle and an internally threaded component screwed onto the threaded spindle. The component includes a plastic element having a first axial end and a second axial end and an interior having a width and a radially inwardly projecting flange at the first axial end, and the flange has an inner diameter less than the width of the interior. A metal element, such as a nut, is fixedly mounted in the interior of the plastic element, and the internal thread of the nut has a maximum diameter greater than the inner diameter of the flange.

Actuator including a threaded spindle and plastic element

The electromechanical actuator cylinder provides a casing, an actuation rod mounted to be movable longitudinally relative to the casing, an electric motor provided with a stator and with a rotating rotor shaft, and a mechanism for converting a rotational movement of the rotor shaft into a linear movement in translation of the actuation rod. The actuator cylinder includes at least one roller bearing for guiding the rotor shaft in rotation relative to the casing and providing at least one row of rolling elements. An inner raceway for the row of rolling elements of the bearing is formed directly on the rotor shaft.

Electromechanical actuator cylinder

An actuator includes a screw mechanism () having a threaded nut () rotatable by an electric motor () about a longitudinal axis (x) and a screw () translatable along the axis between an axially extended position and an axially retracted position. The screw () is connectable to a wire (W) of a Bowden cable (C) having an outer sheath (S). The actuator has a casing () with a first, fixed transversal surface (). A cup () is mounted axially slidably on the casing () and has a second transversal surface () adapted for resting against an end of the sheath (S). A spring () is compressed between the first, fixed transversal surface () and the sliding cup (). The cup () is capable of reaching an axially extended position, corresponding to a released brake condition, and an axially retracted position towards the first fixed transversal surface (), against the bias of the spring (), corresponding to a brake actuated condition.
