Abstract
A gearbox decoupling apparatus and method for powering an accessory system. The gearbox decoupling apparatus employs a worm gear mechanism having an input worm pinion engaged with a worm gear wheel. A threaded rod is engaged with the worm gear wheel. A decoupling adapter is connected to the threaded rod. Rotation of the input worm pinion imparts movement of the decoupling adapter between a first position and a second position. When the decoupling adapter is in the first position, the decoupling adapter is mechanically engaged with a power take-off gear and a power take-off adapter. When the decoupling adapter is in the second position, the decoupling adapter is mechanically engaged with the power take-off gear and disengaged from the power take-off adapter thus allowing an accessory system to be powered by an alternate power source other than a main power source that is permanently connected to the power take adapter.
