Abstract: The invention relates to an assembly comprising: a turbomachine exhaust case (110) that includes an external sleeve and an internal sleeve inside the former, both sleeves extending concentrically about a turbomachine axis, and also includes a plurality of arms extending radially between the sleeves; and an annular part (130) that is centered about the axis, is mounted on one sleeve of the exhaust case, and is located downstream of the exhaust case in the direction in which the air flows inside the turbomachine; the assembly is characterized in that the annular part and the sleeve of the exhaust case on which the annular part is mounted each have a circumferential thread (131, 115), said threads cooperating with each other in order to allow the annular part to be screwed onto the sleeve of the exhaust case.

Abstract: An exhaust casing of a turbine engine for an aircraft which extends along an axis and includes: a central hub, an annular outer shroud and arms which connect the central hub to the outer shroud, at least one yoke for attaching the exhaust casing to the turbine engine being located on the outer shroud and forming at least one lug extending in a plane perpendicular to the axis and protruding toward the exterior of the outer shroud. The outer shroud includes ribs which form a constant excess of the outer shroud, which are located on either side of the at least one lug of the at least one yoke, and which are aligned with the at least one lug.
