Title (EN) FLEXIBLE COUPLING SHAFT FOR TURBINE ENGINE
(FR) ARBRE D'ACCOUPLEMENT FLEXIBLE POUR TURBOMACHINE
Abstract:
(EN) The present disclosure is directed to a shaft assembly (95) for a turbine engine (10), wherein the turbine engine includes a fan or propeller assembly (14) and an engine core (20), and further wherein the fan or propeller assembly includes a gearbox (45), and wherein the engine core includes one or more rotors (32). The shaft assembly (95) includes a fiexible shaft (100) defining a first end (101) and a second end (102) along the axial direction, wherein the first end is connected to the engine core (20) and the second end is connected to the gearbox (45), and wherein a plurality of splines (110) is defined at the second end (102) and coupled to a spline interface (46) at the gearbox (45); and a coupling (120) extended at least partially in the radial direction and coupled to the engine core and the flexible shaft.
(FR) La présente invention concerne un ensemble formant un arbre (95) pour un turbomachine (10), la turbomachine comprenant un ensemble formant un ventilateur ou une hélice (14) et un noyau de moteur (20), et en outre l'ensemble formant un ventilateur ou une hélice comprenant une boîte de vitesses (45), et le noyau de moteur comprenant un ou plusieurs rotors (32). L'ensemble formant un arbre (95) comprend un arbre flexible (100) définissant une première extrémité (101) et une seconde extrémité (102) le long de la direction axiale, la première extrémité étant reliée au noyau de moteur (20) et la seconde extrémité étant reliée à la boîte de vitesses (45), et une pluralité de cannelures (110) étant définie au niveau de la seconde extrémité (102) et couplée à une interface de cannelure (46) au niveau de la boîte de vitesses (45) ; et un couplage (120) s'étendant au moins partiellement dans la direction radiale et étant couplé au noyau de moteur et à l'arbre flexible.
