<p>A drive system 50 for rotating a wheel of an aircraft landing gear includes a motor 52 operable to rotate a drive pinion 64 via a drive path and which can be meshed with a driven gear 66 adapted to be attached to the wheel so as to be capable of rotating the wheel. The drive path comprises a first compensating gear 72 mounted on a common drive shaft 54 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 having a series of rollers arranged to form a ring, each roller being rotatable about a roller axis, and the other of the drive pinion and the driven gear comprises a sprocket. Similarly, one of the first compensating gear and the second compensating gear comprises a roller gear having a series of rollers arranged to form a ring, each roller being rotatable about a roller axis, and the other of the first compensating gear and the second compensating gear comprises a sprocket. 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.</p> |
