Abstract

1363151 Epicyclic gearing ROLLS-ROYCE (1971) Ltd 27 April 1972 [27 April 1971] 11725/71 Heading F2Q In epicyclic gearing comprising a sun gear 10, a plurality of planet pinions 11, and an annular gear 18, the annular gear 18 is relatively flexible and is surrounded by a relatively stiff backing- ring 43 with radial clearance therebetween in which a hydro-dynamic squeeze film of oil is formed. The oil is supplied to the clearance from a tube 46. The oil film opposes deformation of the annular gear 18 and damps vibration. Preferably the stiffness of the backing ring 43 is substantially seven times the stiffness of the annular gear 18.
