Abstract
A rotor assembly and a method of assembling the rotor assembly typically for a turbine engine. The rotor assembly has a rotational axis, at least one rotor, a shaft having an axially extending bore, a tension stud extending axially through the rotor and into the bore for applying an axial load across the rotor and/or shaft. The rotor assembly further has a sleeve located at least partly within the bore and connected to the shaft by a first attachment and to the tension stud by a second attachment, the first attachment is located between the rotor and the second attachment.
Claims15
A rotor assembly for a turbine engine, the rotor assembly comprising:
- a rotational axis,
- at least one rotor,
- a shaft having an axially extending bore,
- a tension stud extending axially through the rotor and into the bore adapted to apply a compressive axial load across the rotor and shaft,
- a sleeve located at least partly within the bore and connected to the shaft by a first attachment and to the tension stud by a second attachment such that the sleeve incurs a compressive axial load,
- the first attachment located between the rotor and the second attachment.
