Abstract
Abstract A gas turbine regenerator assembly and assembly method are described. The regenerator assembly comprises a cylindrical regenerator core, an annular drive member surrounding the cylindrical surface of the regenerator core and separated from it to define an annular space, and a resilient material positioned in the annular space between the drive member and regenerator core. A mounting ring is also located in the annular space. The mounting ring has a discontinuity in it which permits its diameter to be varied to compress the resilient material during assembly. The assembly method of the invention includes the steps of surrounding the cylindrical surface of the regenerator core with the resilient material, placing the annular mounting ring around the resilient material and regenerator core, applying forces to the mounting ring to reduce its diameter, positioning the drive member around the mounting ring, and reducing the previously applied forces to permit the mounting ring diameter to increase.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
A gas turbine regenerator assembly, which comprises: a cylindrical regenerator core, said regenerator core being porous to gases flowing substantially parallel to its axis; an annular drive member surrounding the cylindrical surface of said regenerator core, said annular drive member having an inner diameter greater than the diameter of said regenerator core, an annular space thereby being formed between the inner surface of said annular drive member and the cylindrical surface of said regenerator core; a resilient material positioned in said annular space between said drive member and said regenerator core; and an annular mounting ring, said mounting ring having a discontinuity therein to permit its diameter to be varied, said mounting ring substantially surrounding said resilient material and said regenerator core, said mounting ring being positioned in said annular space and between said resilient material and the inner surface of said annular drive member, and means preventing circumferential movement of said drive member relative to said ring.
Claim 2
Dependent Claim
158 words
A gas turbine regenerator assembly, which comprises: a cylindrical regenerator core, said regenerator core being porous to gases flowing substantially parallel to its axis; an annular drive member surrounding the cylindrical surface of said regenerator core, said annular drive member having an inner diameter greater than the diameter of said regenerator core, an annular space thereby being formed between the inner surface of said annular drive member and the cylindrical surface of said regenerator core; a resilient material positioned in said annular space between said drive member and said regenerator core; and an annular mounting ring, said mounting ring having a discontinuity therein to permit its diameter to be varied, said mounting ring substantially surrounding said resilient material and said regenerator core, said mounting ring being positioned in said annular space and between said resilient material and the inner surface of said annular drive member, and means preventing circumferential movement of said drive member relative to said ring.
Claim 3
Dependent Claim
71 words
A regenerator in accordance with claim 1, wherein said annular mounting ring further includes at least one tab extending radially outward from its annular portion and wherein said circumferential movement prevention means comprises a protrusion on said annular drive member extending in an axial direction, said protrusion being positioned to engage said tab on said mounting ring, thereby, to prevent rotational movement of said mounting ring relative to said drive member.
Claim 4
Dependent Claim
39 words
A regenerator assembly in accordance with claim 1, wherein said annular mounting ring further includes a plurality of tabs extending radially outward from its annular portion for preventing axial movement of said mounting ring relative to said drive member.
Claim 5
Dependent Claim
39 words
A regenerator assembly in accordance with claim 1, wherein said annular mounting ring further includes a plurality of tabs extending radially inward from its annular portion for preventing axial movement of said resilient material relative to said mounting ring.
Claim 6
Dependent Claim
39 words
A regenerator assembly in accordance with claim 3, wherein said annular mouNting ring further includes a plurality of tabs extending radially inward from its annular portion for preventing axial movement of said resilient material relative to said mounting ring.
Claim 7
Dependent Claim
51 words
A regenerator assembly in accordance with claim 5, wherein said assembly further comprises a protrusion on said annular drive member, said protrusion being positioned to engage one of said radially outwardly extending tabs on said mounting ring, thereby, to prevent rotational movement of said mounting ring relative to said drive member.
