Abstract:
A reduction gear with epicyclic gear train including an annulus gear, and at least one planet gear rolling on the annulus gear and able to rotate about a planet spindle borne by a planet carrier is provided. The planet spindle is mounted such that it can itself rotate about its axis relative to the planet carrier. The reduction gear is suitable for mounting in a high bypass ratio jet engine for driving the fan thereof.
