Abstract
A disengagement/disconnect assembly for disengaging a generator from a gear box includes an inner ball screw having an angled threading on an outer surface thereof and surrounding and operatively engaged to a rotating generator drive shaft to cause rotation of the inner ball screw, the inner ball screw having axial dog teeth engaged to corresponding teeth of the gear box drive shaft, an outer ball screw surrounding and normally rotating with the inner ball screw and having a spherical ball and an angled ball track between the inner and outer ball screws, a lock, and a brake for slowing or stopping rotation of the outer ball screw so that the inner ball screw rotates relative to the outer ball screw along the ball track and slides axially toward the lock thereby disengaging the generator from the gear box drive shaft.
