Abstract: An epicyclic gearing has a plurality of planet gears arranged about a transmission axis so as to form two arrays symmetrical with respect to a plane orthogonal to the transmission axis; the gearing has a body which, on one side, is adapted to be connected to a rotating member and, on the other side, is coupled to a ring; the ring has a plurality of relatively thin plate sectors and a plurality of pins, which extend in cantilever fashion and in opposite directions from the plate sectors and each support a respective planet gear; coupling between the aforesaid body and the ring defines at least one degree of freedom in rotation about a radial axis to allow a relative movement under load between the two components.
