Abstract
An improved gear ring for epicyclic gear trains is formed from a plurality of concentric ring elements shrink fitted to each other, whereby increased flexibility is achieved without increasing stress levels in the ring. The ring elements may be separated by a layer of elastomeric material having a low modulus of elasticity. A method of making such a gear ring is disclosed.
