Abstract

Stacked wheels of the rotor of a rotary machine are axially coupled to one another by tie bolt assemblies. Each tie bolt assembly includes a stud having forward and aft ends. The aft end of the stud includes a self-locking nut to thereby lock the stud/nut assembly against rotation relative to the rotor.
