Claims4
In combination with a gas turbine engine having a rotating blade and mounting ring assembly adapted for rotation about a first axis, the assembly including a plurality of blades, each of said blades being rotatably mounted on said ring for rotation about a second axis, said assembly further including a plurality of bearing assemblies each associated with one of said blades and disposed around the periphery of said rotating ring, the improvement comprising:
- a substantially continuous seating surface on said ring, said seating surface adapted to engage and seat said plurality of bearing assemblies.
In a gas turbine engine including a blade and mounting ring assembly adapted to be rotatable about a first axis, said assembly including a plurality of blades rotatably secured to said ring, the improvement comprising:
- an annular ring extending circumferentially about, axially along and radially from said first axis, said ring having a plurality of circumferentially spaced apertures extending radially through said ring and a radially inwardly facing substantially continuous axially and circumferentially extending seating surface;
- a plurality of radially extending blades, each blade having at its radially innermost end a shank portion partially disposed within one of said apertures;
- means for cooperating with said shanks for retaining said shank portions disposed within said apertures;
- and
- a plurality of circumferentially spaced bearing assemblies each disposed adjacent one of said shanks and each including an outer race having a radially outwardly facing surface, said radially outwardly facing surface of at least two of said bearing assemblies engaging said seating surface.
