METHODS FOR MANUFACTURING A DRUM AND A SPRING BRAKE FOR AN ELECTROMECHANICAL ACTUATOR, ASSOCIATED ELECTROMECHANICAL ACTUATOR AND HOME AUTOMATION INSTALLATION

摘要

A method relates to the manufacture of a drum (23) for a spring brake for an electromechanical actuator, the drum (23) comprising a housing (26) configured to house at least one helical spring, an input member and an output member. The housing (26) has an internal friction surface (27) configured to cooperate with at least one coil of the helical spring. The method comprises at least one step of mechanical surface treatment of the inner surface (27) of the housing (26) of the drum (23), the mechanical surface treatment of the inner surface (27) of the housing (26) of the drum (23) being a step of creating grooves (50a, 50b) on the inner surface (27) of the housing (26).
