Abstract: The invention concerns a rotary assembly for a turbomachine, comprising a disk of which the outer periphery is formed from an alternation of cavities and teeth (12), and blades extending radially from the disk and of which the roots (16) are engaged axially and held radially in the cavities of the disk. According to the invention, the teeth of the disk and the blade roots comprise, at the upstream and/or downstream axial ends of same, axial shoulders (74, 76) disposed circumferentially end-to-end in alternation and together forming a cylindrical surface (78) facing radially towards the inside of the disk.

Abstract: The invention concerns a rotary assembly for a turbomachine, comprising: a disc (16) having an external periphery having an alternation of slots (22) and teeth (20), blades (14) extending radially from the disc (16), and the roots (24) of which are engaged axially and held radially in the slots (22) of the disc, platforms (30) extending circumferentially from the blades (14) and which are arranged circumferentially end to end, opposite each other, axial sealing means upstream and/or downstream of an annular zone extending radially from the platforms (30) as far as the disc (16). According to the invention, the sealing means comprise radially an internal annular part (64) and an external annular part (66) structurally separate from each other, and the facing radial ends of which are adapted for a relative radial movements by sliding sealingly, only an absorption of the centrifugal forces of the external part (66) being provided rotationally by the platforms (30).

Abstract: A rotary assembly for a turbine engine is provided. The assembly includes a rotor with two consecutive rotor stages equipped with a plurality of movable vanes, and an annular rotor shroud connecting the two consecutive rotor stages; and a stator including a stator stage, provided with a plurality of fixed vanes and disposed between the two rotor stages, and an annular stator ring mounted on the fixed vanes. Either the rotor shroud or the stator ring bears at least one wiper designed to cooperate with an abradable track on the other of the rotor shroud and stator ring, such that the rotor shroud includes at at least one of its upstream or downstream ends an inclined contact portion resting on an inclined bearing surface of the corresponding rotor stage, the bearing surface being the outer surface of a projection extending from a base portion of the corresponding rotor stage.
