Patent ID: 7552591

Claim:
A twin spool turbine engine comprising: a high-pressure rotor, a low-pressure rotor, at least one accessory gearbox, drive means for driving coaxial transmission shafts that transmit movement to the accessory gearbox, wherein the drive means comprises a high-pressure drive pinion secured to the high-pressure rotor near its upstream end, a low-pressure drive pinion secured to the low-pressure rotor upstream of the high-pressure rotor, and a power take-off module in direct mesh with the drive pinions, driving the transmission shafts, wherein said power take-off module comprises a cylindrical portion secured to said coaxial transmission shafts and a frustroconical portion extending internally from said cylindrical portion, said power take-off module further comprising a high pressure take-off pinion secured to said frustroconical portion and in direct mesh with said high-pressure drive pinion, and a low pressure take-off pinion secured to said frustroconical portion and in direct mesh with said low-pressure drive pinion.
