TAPERED COLLET CONNECTION OF ROTOR COMPONENTS

摘要

A connection between an annular sleeve (52) on a gas turbine engine first rotor component (34) includes an annular tapered conical slot (53) extending axially inwardly into the sleeve from an annular opening and tapers axially into the sleeve from the opening. An annular rim (64) of a second rotor component (12) is received within the conical slot and includes a rim inner conical surface (70) mating with and contacting a sleeve inner conical surface (56) in part bounding the conical slot. A sleeve cylindrical outer surface (60) in part bounds the conical slot in the sleeve and a rim outer cylindrical surface (72) on the annular rim contacts the sleeve cylindrical outer surface. An annular lip (80) may extend radially inwardly from the sleeve and sleeve inner conical surface a the annular opening to the conical slot. The connection may be used between a first stage disk and an interstage seal (12).
