    摘要： A turbine stage for a turbomachine, the stage comprising a rotor wheel mounted inside a sectorized ring carried by an outer casing, and a sectorized nozzle fastened to the casing downstream from the wheel, each ring sector having a downstream end that is held bearing radially outwards against a cylindrical rail of the casing by means of the nozzle, the casing rail including an annular row of through radial notches reducing the areas for heat exchange by conduction both between the casing and the ring sectors and between the casing and the nozzle.

    摘要： The connection assembly of an arm (10) to a sleeve (11) is carried out substantially by parts of axes (21) crossing the arm and the spacers (26) between the parts of axes and the sleeve and the assembly bolts (32). The assembly and the disassembly are easy, even with highly reduced encumbrance, the connection is light and devoid of high internal efforts and a good position precision is obtained.Application to the stators with an exterior sleeve and, an interior hub and radial link arms, which are encountered in certain turbomachines as in aeronautics.
