Abstract

Pour monter un ensemble mécanique (10) comportant deux sous-ensembles mécaniques (12, 14) entre lesquels est préservé, dans un état opérationnel de l’ensemble mécanique (10), un logement annulaire (50) pour loger des corps roulants (52), l’un des deux sous-ensembles mécaniques (12, 14) étant pourvu d’un canal d’accès (64) reliant le logement annulaire (50) à l’extérieur, on positionne les sous-ensembles mécaniques (12, 14) dans une position de montage, de façon à ce que soit formé un volume annulaire de montage (78) supérieur au volume du logement annulaire (50), puis on insère chacun des corps roulants dans un espace interdentaire (74) d’un peigne (70) que l’on a au préalable placé en regard du canal d’accès (64) et l’on insère des entretoises individuelles (54), par le canal d’accès (64), chacune entre deux corps roulant (52), après avoir positionné le peigne d’indexation (70) en positionnant une dent (72) en regard du canal d’accès (64).
