摘要：A method of engaging a drive system with a rotating wheel of an aircraftlanding gear. A motor is operated to rotate a pinion which is moved from a neutralposition to a contact position in which it contacts a rotating driven gear at an initial

contact time, the rotating driven gear being mounted to a rotating wheel of an aircraftlanding gear; then after the initial contact time moving the pinion further to a meshingposition where the pinion meshes with the driven gear. A centre-to-centre distancebetween the pinion and the driven gear reduces as the pinion moves to the contactposition and to the meshing position. The driven gear has N teeth or rollers, the pinionhas N teeth or rollers which mesh with the teeth or rollers of the driven gear when thepinion is at the meshing position. The pinion and driven gear are rotating at angularvelocities ω and ω respectively at the initial contact time. A sync ratio [(ω*N) / (ω*N)] atthe initial contact time is not 1, and is preferably less than 1.
