Abstract
An epicyclic gear train comprising a sun gear, an outer ring gear, and a plurality of planet gears carried by a common planet carrier. The planet carrier comprises a support and a plurality of spindles carried by the support, each spindle having a carrier segment extending away from the support to a distal end, each planet gear being arranged around a the carrier segment. Each distal end is separated from another distal end that is adjacent thereto by a distance, and the epicyclic gear train includes a holder system for maintaining the distance within a predefined range regardless of the force applied to each spindle.
