A rotating arrangement 1 comprising a rotating assembly is mounted on an associated bearing 2 defining a geometric axis of rotation A for the rotating assembly. The rotating assembly comprising first part 4 mounted on the bearing 2 for rotation relative to the bearing about the geometric axis A; a second part 5 engaged with the first part 4 for independent relative angular adjustment about a second axis B, eccentric to the geometric axis A; and a third part 6 engaged with the second part 5 for independent relative angular adjustment about a third axis C, eccentric to the second axis B. Relative angular adjustment about one or both of the second and third axes B,C can be used to adjust the position of the centre of mass of the rotating assembly to be substantially co-incident with the geometric axis of rotation A. |
