Abstract
An example turbomachine shroud assembly includes an annular shroud configured to receive a rotating component. A radially outer surface of the annular shroud establishes positioning slots and relief slots. The positioning slots are configured to receive a support finger that limits radial movement of the annular shroud. The relief slots are different than the positioning slots.
Claims18
A turbomachine shroud assembly, comprising:
- an annular shroud configured to receive a rotatable component, a radially outer surface of the annular shroud establishing a plurality of positioning slots and a plurality of relief slots that are different than the positioning slots, the plurality of positioning slots each configured to receive a support finger that limits radial movement of the annular shroud, the plurality of positioning slots each extending across an entire axial length of the annular shroud.
A turbomachine assembly, including:
- a component configured to rotate about an axis;
- a shroud configured to receive the component;
- a clamp ring including fingers that extend axially and are received within positioning slots established within the shroud such to limit radial movement of the shroud relative to the clamp ring, wherein the shroud establishes at least one relief slot;
- and
- including a mica gasket positioned axially between the clamp ring and the shroud.
