ABSTRACT:
The present invention provides for outer diameter piloting of a nut that secures stacked components to a tie-shaft or other threaded components used to axially secure one or more rotating components. Unlike conventional inner diameter piloting methods, machining a precise inner diameter of the nut is not needed. The nut face of the present invention has superior perpendicularity with the tie-shaft and the radial pilot is not lost when the nut is loaded. Outer diameter nut piloting may be conducted by using a nut alone or a nut in combination with a nut spacer, a pocket in the rotor, a nut spacer seat, or a nut piloting insert.
