More Information
Summary:A shaft assembly for a gas turbine engine that includes a shaft with a threaded shaft segment, an annular rotor disposed on the shaft, and annular stack nut. The stack nut includes a base nut segment and a clamping nut segment. The base nut segment includes a threaded nut bore that is mated with the threaded shaft segment. The clamping nut segment axially extends from the base nut segment to a load bearing surface. The clamping nut segment includes a radial thickness that decreases as the clamping nut segment extends from the load bearing surface towards the base nut segment. The load bearing surface exerts a force against the rotor securing the rotor to the shaft.
