In order to facilitate the disassembly of a transmission shaft in a turbomachine, an arm for turbomachine casing comprises a body provided with a recess housing a removable part which delimits a shaft housing and is capable of being inserted through a first opening of the recess by means of sliding movement of the removable part parallel to the direction of a central axis of the shaft housing, the first opening of the recess being configured for being arranged opposite an orifice within a casing outer shell ring of the turbomachine.

Arm for turbomachine casing comprising a body and a removable part

The invention relates to an assembly on an engine, which comprises a first and a second piece mounted so as to rotate relative to one another. A connecting device is provided between such pieces. It comprises a first annular part defining a flange fixed to the first piece a second annular part extending substantially parallel with the axis of rotation of the engine and studs connecting the first and second annular parts together. An interface for the rotational sliding about said axis is positioned between the second annular part and the second piece. The second annular part is sectorized.
