ABSTRACT:
A twin-spool gas turbine engine including a high-pressure rotor and a low-pressure rotor, which rotors are mounted in bearings supported by an intermediate casing, at least one accessory gear box, and a drive device which drives radial and coaxial shafts for transmitting movement to the accessory gear box is disclosed. The drive device includes a high-pressure drive gear driving one of the radial shafts and connected to the high-pressure rotor and a low-pressure drive gear connected to the low-pressure rotor upstream of the high-pressure drive gear and driving the other of the radial shafts. The low-pressure drive gear is supported in the intermediate casing by an axial-positioning bearing.
