摘要： 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 externally threaded opposite ends. A forward end of each stud is threaded into a non-rotatable windage nut. The aft end of each stud is secured by a primary nut having a plurality of facets, a jam nut locked against the primary nut and an anti-rotation cover between the jam nut and primary nut. The anti-rotation cover includes wings engaged against a next-adjacent wheel, preventing rotation of the cover relative to the rotor. Internal surfaces of the cover have facets greater in number than the number of facets on the primary nut whereby fine clock orientation of the cover relative to the adjacent wheel is obtained. The cover and primary nut are thus locked against rotation, thereby locking the stud/nut assembly against rotation relative to the rotor.
