Abstract
A method for manufacturing a mechanical reducer for an aircraft turbomachine including a central pinion, an outer crown, N planet pinions, where N≥3, each planet pinion including a first stage meshing with the central pinion, and a second stage meshing with the outer crown, the method including the assembly marking, wherein N teeth of the central pinion are marked, and N pairs of teeth of the first stage of each planet pinion are marked, the N planet pinions each being marked identically, and the assembly of the mechanical reducer, so that the teeth of the pairs of marked teeth of the first stage of each planet pinion are disposed on either side of a marked tooth of the central pinion.

A method for manufacturing a mechanical reducer for an aircraft turbomachine comprising a central pinion and an outer crown coaxial with each other around a main axis of rotation, and N planet pinions where N≥3, each being movable about a secondary axis of rotation parallel to the main axis of rotation and each comprising a first stage meshing with the central pinion, and a second stage with a diameter smaller than the diameter of the first stage meshing with the outer crown, the method comprising:
- assembly marking, wherein N teeth of the central pinion and/or of the second stage of each planet pinion are marked, and N pairs of teeth of the first stage of each planet pinion and/or of the outer crown are marked, the N planet pinions each being marked identically,
- assembling the mechanical reducer, so that the teeth of the pairs of marked teeth of the first stage of each planet pinion are disposed on either side of a marked tooth of the central pinion and/or so that the teeth of the pairs of marked teeth of the outer crown are disposed on either side of a marked tooth of the second stage of each planet pinion.
