Tubular electromechanical actuator, home-automation installation comprising such an actuator, and method for assembling such an actuator

A tubular electromechanical actuator for a closure or sun protection home automation installation, the electromechanical actuator comprising at least:

• an assembly, the assembly comprising:
• an electronic control unit,
• an electric motor,
• a reduction gear, and
• an output shaft;
• a casing, the casing being hollow and configured to house the assembly, the casing comprising a first end and a second end, the second end being opposite the first end, the output shaft protruding past the casing at the first end of the casing, in an assembled configuration of the electromechanical actuator;
• and
• a closure element of the second end of the casing, the closure element protruding past the casing at the second end of the casing, in the assembled configuration of the electromechanical actuator, wherein,
• the electromechanical actuator also comprises an interface element, the interface element being arranged between the closure element and the electronic control unit with an axial play spacing being provided between the closure element and the interface element, and
• the interface element comprises a first accommodation, with an inhibiting element positioned within the first accommodation, the inhibiting element inhibiting an axial length of the axial play spacing between the closure element and the interface element along an axial direction of the electromechanical actuator along a major length of the electromechanical actuator which goes along a rotation axis of the casing extending from the second end of the casing toward the first end of the casing, wherein,
• the axial play spacing being adjustable by adjustment of the inhibiting element,
• the first accommodation of the interface element is a bore, and
• the inhibiting element is a screw located in the bore, the screw being adjustable to vary the axial play spacing by adjusting a position of the bore relative to the closure element through an unscrewing or a screwing operation of the screw.

A method for assembling a tubular electromechanical actuator for a closure or sun protection home automation installation, the electromechanical actuator comprising at least:
