Abstract Assembly method for a gas turbine regenerator assembly 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 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.
A method for assembling a gas turbine regenerator assembly, said assembly comprising a cylindrical regenerator core, an annular drive member, and a resilient material positioned between said drive member and said regenerator core, said method including the steps of: surrounding the cylindrical surface of said regenerator core with said resilient material; placing an annular mounting ring, said mounting ring having a discontinuity to permit its diameter to be varied, around said resilient material and regenerator core; applying forces to said mounting ring to reduce its diameter and simultaneously to compress said resilient material; positioning said drive member around said mounting ring; and reducing the forces previously applied to said mounting ring, thereby, to permit its diameter to increase.
