Abstract

L'invention concerne une partie tournante (1) d'une turbomachine comprenant : - un premier rotor (10) comprenant une bride aval (14) pourvue de cannelures (13), - un deuxième rotor (20) comprenant une bride amont (24) pourvue de cannelures (23), et - un manchon (30) présentant une surface interne (31) cannelée, ledit manchon (30) étant rapporté et fixé sur la bride aval (14) et la bride amont (24) de sorte que la surface interne (31) cannelée vienne en prise avec les cannelures (13, 23) de la bride aval (14) et de la bride amont (24) pour raccorder mécaniquement le premier rotor (10) et le deuxième rotor (20) et transmettre un couple entre le premier rotor (10) et le deuxième rotor (20).The invention relates to a rotating part (1) of a turbomachine comprising: - a first rotor (10) comprising a downstream flange (14) provided with splines (13), - a second rotor (20) comprising an upstream flange (24) ) provided with splines (23), and - a sleeve (30) having an internal surface (31) splined, said sleeve (30) being attached and fixed to the downstream flange (14) and the upstream flange (24) so that the splined internal surface (31) engages with the splines (13, 23) of the downstream flange (14) and of the upstream flange (24) to mechanically connect the first rotor (10) and the second rotor (20) and transmitting torque between the first rotor (10) and the second rotor (20).
