Patent ID: 7946403

Claim:
A disengagement assembly for disengaging a generator from an engine comprising: a rotatable inner ball screw having an angled threading on an outer surface thereof, the inner ball screw fixedly connected to an axially displaceable engagement member; an outer ball screw surrounding the inner ball screw; an angled ball track between the inner ball screw and the outer ball screw; a ball bearing traveling on the angled ball track; and a brake capable of 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 thereby disengaging an engaged generator from an engine; the engagement member having a plurality of circumferentially disposed teeth; the teeth having a distal circumferential width at their distal ends and a proximal circumferential width at their proximal ends; wherein the distal circumferential width is greater than the proximal circumferential width.
