Abstract
A drive system for rotating one or more wheels of an aircraft landing gear for ground taxiing and/or spin-up prior to landing has a motor operable to rotate a first drive pinion via a first drive path, and a driven gear adapted to be fixed to the wheel. The drive system has a first configuration in which the first drive pinion meshes with the driven gear to permit the motor to drive the driven gear via the first drive path. One of the first drive pinion and the driven gear comprises a first sprocket and the other comprises a series of rollers arranged in two or more rows, each row of rollers being arranged to form a ring. The rollers are rotatable about pins fixed to an annular support member, and adjacent rows may be out of phase by a fraction of roller pitch.
