Beschreibung
Zusammenfassung:	A fan module for an aircraft turbine engine includes a fan with a fan shaft and variable-pitch fan blades. The fan module further includes an oil transfer device transfers oil between a stator and an actuator that controls the pitch of the fan blades the device includes a stator ring having an inner cylindrical surface and internal oil ducts, each of which opens onto the inner cylindrical surface. A shaft is engaged in the stator ring and rotates about an axis inside the ring. The shaft includes an outer cylindrical surface extending inside said inner cylindrical surface. The shaft has internal oil ducts, each of which opens onto said outer cylindrical surface A rolling bearing is mounted between the ring and the shaft, on each side of the plain bearing.
