Tubular electromechanical actuator, home automation equipment comprising such an actuator and method for connecting such an actuator

A method for assembling a tubular electromechanical actuator for a closure or sun protection home automation installation,

• the electromechanical actuator comprising at least:
• an electric motor,
• a casing, the casing being hollow and configured to house at least the electric motor, the casing comprising a first end and a second end, the second end being opposite the first end,
• a closure element, the closure element closing off the second end of the casing, the closure element comprising protrusions configured to cooperate with recesses of the casing, the recesses being arranged at the second end of the casing, and
• a ring, the ring being positioned outside of an outermost circumference of the casing and at the second end of the casing, the ring being a monobloc part, the ring being rotatable with respect to the closure element and forming a bearing for a winding tube,
• the method comprising at least the following steps:
• assembling the ring relative to the closure element, and
• assembling the casing relative to the closure element and the ring,
• wherein the method also comprises at least:
• during the step for assembling the ring relative to the closure element, a step for positioning clearances of the ring relative to the protrusions of the closure element, a first step for moving the ring relative to the closure element by a translational movement of the clearances of the ring relative to the protrusions of the closure element, then a second step for moving the ring relative to the closure element by a rotational movement, so as to block a translation of the ring with respect to the closure element by causing a stop of the ring to bear against the protrusions of the closure element, and
• during the step for assembly of the casing relative to the closure element and the ring, a step for insertion of the casing between the closure element and the ring, then a step for introduction of the protrusions of the closure element inside recesses arranged at the second end of the casing.
