A landing gear hinge shaft is installed on an aircraft structure using at least two ball joints (22), at least one of which is adjustable. The differences between the theoretical and real positions of the centers of the balls are measured, and the adjustments that have to be made to bring the centers of the balls back to their theoretical positions is deduced. This is done by making a first adjustment in the axial direction using a shim (30) and a second adjustment in the radial direction by adjusting the rotation of an inner cage (34) and an outer cage (36) of the ball joint. The inner and outer cages have eccentric axes that facilitate the adjustment.
Un arbre d'articulation de train d'atterrissage est monté sur la structure d'un avion à l'aide d'au moins deux joints à rotule (22) dont au moins un est réglable. Les différences entre les positions théoriques et réelles des centres des rotules sont mesurées et les valeurs des réglages qui doivent être faits pour ramener les centres des rotules à leurs positions théoriques sont soustraites. Il s'agit d'abord de faire un premier réglage dans la direction axiale à l'aide d'une cale (30), puis un deuxième réglage dans la direction radiale par réglage de la rotation d'une cage intérieure (34) et d'une cage extérieure (36) du joint à rotule. Les cages intérieures et extérieures possèdent des axes excentriques qui facilitent le réglage.
