A drive system 50 for rotating a wheel 16 of an aircraft landing gear includes a motor 52 operable to rotate a drive pinion 60,64 via a drive path and a driven gear 20,66 adapted to be attached to the wheel so as to be capable of rotating the wheel. The drive system has a drive configuration in which the drive pinion is capable of meshing with the driven gear to permit the motor to drive the driven gear via the drive path. The drive path comprises a first compensating gear 74 and a second compensating gear 72 which is meshed with the first compensating gear. One of the drive pinion and the driven gear comprises a roller gear and the other of the dive pinion and the driven gear comprises a sprocket. Vibrations caused by fluctuations in the transfer of torque between the drive pinion and the driven gear can be isolated within the common drive shaft, and prevented from being transmitted through the drive train to the landing gear by compensating torque fluctuations between the first and second compensating gears. The teeth of the first and second compensating gears may be arranged to form respective first and second non-circular shapes. |
