Abstract:

A re-settable mechanical disconnect includes a fixed flange and a retracting flange, each including a plurality of ramped teeth that mate together. The incline of the ramp of each tooth may allow power to be transmitted from the engine to the generator at required speeds and may aid disengagement of the retracting flange form the fixed flange. The mechanical disconnect may be activated in the case of a generator failure and may be re-set and reused once the cause for activation is cleared. An actuator assembly may provide an external force in axial direction that may initiate disengagement and re-engagement of the retracting flange and the fixed flange. The mechanical disconnect may be suitable for, but not limited to, applications in the aircraft and aerospace industries, for example, for disengaging a variable frequency generator from an engine in the case of generator failure thus preventing damage to the gearbox.
