Method for mounting an axle in a bogie, and associated installation

A method for mounting an axle (12) in a bore (14) of a bogie (16) mounted on a landing gear (18) of an aircraft, the landing gear (18) being in a gear-down position, the bore (14) extending in a substantially horizontal direction referred to as the axle installation direction, between a first open end (14a) and a second open end (14b), the method comprising:

• a) supplying a mobile bearing structure (30) comprising means for moving the axle (12) which are able to move along a direction substantially parallel to the axle installation direction,
• b) installing the axle (12) on the means for moving the axle,
• c) aligning the axis (C) of the axle (12) with the axis (B) of the bore (14), this step comprising:
• positioning a reference mark (110) on the mobile bearing structure (30) and in such a manner that the axis (B) of the bore (14) intercepts said reference mark (110), and
• positioning the axle (12) so that the axis (C) is aligned with said reference mark (110) along the installation direction,
• d) inserting the axle (12) into said bore (14) of the bogie (16) by moving the means for moving the axle (12) along the direction substantially parallel to the axle installation direction.
