Abstract

Dispositif de connexion (1) d'une partie fixe de turbomachine (2) et d'un pied (31) de distributeur (3) d'une turbine de turbomachine, la turbomachine comprenant un axe de turbomachine, le dispositif comprenant un flasque (8) annulaire, le flasque (8) étant adapté pour être connecté de manière solidaire à la partie fixe de turbomachine (2) et pour être connecté au pied (31) du distributeur, le dispositif étant caractérisé en ce que le flasque comprend une première portion (81) disposée en amont d'une deuxième portion (82) lorsque le dispositif est connecté à la partie fixe de turbomachine (2) et au pied du distributeur (31), la première portion (81) étant plus éloignée de l'axe de la turbomachine que la deuxième portion (82) afin de conférer une souplesse axiale au dispositif.Connecting device (1) of a fixed turbine engine part (2) and a distributor foot (31) (3) of a turbomachine turbine, the turbomachine comprising a turbomachine axis, the device comprising a flange ( 8), the flange (8) being adapted to be integrally connected to the fixed part of the turbomachine (2) and to be connected to the foot (31) of the distributor, the device being characterized in that the flange comprises a first portion (81) disposed upstream of a second portion (82) when the device is connected to the fixed portion of the turbomachine (2) and the foot of the distributor (31), the first portion (81) being further away from the axis of the turbomachine than the second portion (82) to impart axial flexibility to the device.
