摘要：: The invention relates to a radial control shaft (48) for a device for controlling the pitch of fan blades of a turbine engine having an unducted fan, the shaft comprising an external portion (52) that is designed to be mounted in the control device from its outside and to be coupled to at least one fan blade (26) in order to adjust its pitch, and an internal portion (50), independent of the external portion, that is designed to be mounted from the inside of the control device, to be connected to a load transfer bearing (40) in order to pivot the shaft about a radial axis (Z-Z), and to close an oil enclosure in which said bearing is housed, the external and internal portions of the shaft being coupled to each other. The invention also relates to a method of mounting such a shaft and to a control device including such a shaft.
