摘要： A method relates to the manufacture of a drum for a spring brake for an electromechanical actuator, the drum including a housing configured to house at least one helical spring, an input member and an output member. The housing has an internal friction surface configured to cooperate with at least one coil of the helical spring. The method includes at least one step of mechanical surface treatment of the inner surface of the housing of the drum, the mechanical surface treatment of the inner surface of the housing of the drum being a step of creating grooves on the inner surface of the housing.

摘要： Disclosed is an electromechanical actuator including a spring brake including a helical spring, a drum, an input member and an output member. The drum includes a friction surface configured to cooperate with at least one turn of the spring. The output member includes at least one lug. The lug includes a recess provided with at least a first bearing surface configured to cooperate with one of the first and second legs of the spring. The first bearing surface of the recess is inclined with respect to an axis of rotation of the brake at an angle of inclination of non-zero value.
