Fan module having variable-pitch blades

A fan module having variable pitch blades for a propulsion assembly having a longitudinal axis (X), the module comprising:

• a rotary casing which rotates about the longitudinal axis (X) and carries the blades,
• a system configured to change the pitch of the blades, the system comprising a control device and a connection mechanism, the control device comprising an annular actuator centered on the longitudinal axis (X) having a stationary body fitted to the rotary casing and a body movable in translation relative to the stationary body along the longitudinal axis (X), the movable body being coupled to a synchronizing ring gear of the connection mechanism, said synchronizing ring gear being connected to the blades and configured to be driven in translation along the longitudinal axis (X) by the movable body so as to change the pitch of the blades;
• and
• a feathering device configured to feather the blades, said feathering device comprising an annular row of fly-weights carried by the rotary casing,
• wherein the annular row of fly-weights is coupled to the synchronizing ring gear, each of the fly-weights being connected to the synchronizing ring gear by a connecting rod, a first and a second end of which comprise ball-and-socket joints, and the fly-weights being capable, under the centrifugal effect, of being displaced into a position in which the synchronizing ring gear imposes a feathered position on the blades, and wherein the system configured to change the pitch of the blades is devoid of a load transfer bearing.
