A drive system 100 for an aircraft landing gear comprising a pinion gear 110, a drive shaft 120 arranged to rotate the pinion gear about a drive axis and a driven gear 130 arranged to mesh with the pinion gear and to be rotatable by the pinion gear. The driven gear is connectable to a wheel 200 of the landing gear to be capable of rotating the wheel about a wheel axis. A flexible interface is provided by a coupling member 300 that comprises a crowned spline joint and is located between the drive shaft 120 and the pinion gear 110. The crowned spline joint is arranged to permit tilting of the pinion gear relative to the drive axis. The drive system may include a first spline joint between the drive shaft and the pinion gear that is arranged to permit tilting of the pinion gear relative to the drive axis and include a second spline joint that is arranged to permit translation of the pinion gear along the drive axis relative to the drive shaft. |
