Abstract: The disconnect arrangement for high speed aircraft generators includes disconnectable rigid, torque transmitting spring loaded curvic gears coupled between the driving and driven shafts. A plurality of flexibly supported sear members mounted on the driven shaft engage the movable member of the curvic gears. The sears have tapered faces which engage correspondingly tapered shoulders on the movable curvic gear member. The sears are latched to hold the curvic gear members in contact by the armature of an electromagnet. The armature normally rides over the top of the gears maintaining them in contact with the tapered shoulder of the curvic gear member. When the electromagnetic armature is actuated to disengage the driving and driven shafts, the armature moves axially. This removes the retaining force from the tapered sears, allowing them to flex outwardly.
