The invention proposes a drive system (50) for rotating a wheel (16) of an aircraft landing gear (10), the drive system including: a motor (52) operable to rotate a drive pinion (60) via a drive path; and a driven gear (20) 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 (72) mounted on a common drive shaft with the drive pinion so as to be capable of rotating in tandem with the drive pinion, and a second compensating gear (74) which is meshed with the first compensating gear. One of the drive pinion and the driven gear comprises a roller gear (34) having a series of rollers (36a, 36b) arranged to form a ring, each roller being rotatable about a roller axis, and the other of the dive pinion and the driven gear comprises a sprocket. T he teeth of the first and second compensating gears are arranged to form respective first and second non-circular shapes. In this way, 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.
