Abstract
A support assembly and method for supporting an internal assembly in a casing of a turbomachine are provided. The support assembly may include a support member that may be slidably disposed in a recess formed in the internal assembly and configured to engage an inner surface of the casing. A biasing member may be disposed in a pocket extending radially inward from the recess. The biasing member may at least partially extend into the recess and may be configured to apply a biasing force to the support member disposed therein.
Claims6
A turbomachine, comprising:
- a casing having an inner surface;
- an internal assembly disposed within the casing and comprising a plurality of recesses formed in an outer surface of the internal assembly, each recess comprising a plurality of pockets extending radially inward from the respective recess;
- and
- a plurality of support assemblies, each support assembly disposed at least partially within a respective recess of the plurality of recesses and comprising:
- a support member slidably disposed in the respective recess and configured to engage the inner surface of the casing, and
- a plurality of biasing members, each biasing member disposed within a respective pocket of the plurality of pockets of the respective recess and at least partially extending into the respective recess, and configured to apply a biasing force to the support member,
- wherein each support member comprises a contact member and a backing member, the contact member being configured to engage the inner surface of the casing and the backing member being configured to be engaged by a respective plurality of biasing members, and further wherein the contact member of each support member has a protuberance configured to mate with a groove formed in a respective backing member.
