The invention relates to a turbine engine (1) comprising: a rotor (3) supporting a blade (5) and guided by means of bearings (6, 7); a control system for controlling the blade (5), which is solidly connected to the rotor (3) and which comprises an actuator (9) driven by energy, said control system (8) being disposed axially upstream of the bearings (6, 7); and a device (10) for transferring said energy, disposed axially between the bearings (6, 7) and comprising a stationary member (11) and a moving member (12). The rotor (3) comprises a support ring (14) supporting the blade (5) and a shaft (15) having a frustoconical portion (16) and a cylindrical portion (17) on which the bearings (6, 7) and the moving member (12) are mounted, said frustoconical portion (16) extending about the cylindrical portion (17).
Turbomachine (1) comprenant : un rotor (3) portant une pale (5) et guidé via des paliers (6, 7); un système de commande de ladite pale (5) solidaire dudit rotor (3) et comprenant un actionneur (9) mis en mouvement par une énergie, ledit système de commande (8) étant disposé axialement en amont desdits paliers (6, 7); un dispositif de transfert de ladite énergie (10) disposé axialement entre les paliers (6, 7), et comprenant un organe fixe (11) et un organe mobile (12); 15 le rotor (3) comprenant un anneau de support (14) de ladite pale (5) et un arbre (15) présentant une portion tronconique (16) et une portion cylindrique (17) sur laquelle sont rapportés lesdits paliers (6, 7) et ledit organe mobile (12), la portion tronconique (16) s'étendant autour de la portion cylindrique (17).
