Epicyclic gear system having torsional fuse, torsional fuse in drivetrain system, and method of operating drivetrain system

Abstract:

A torsional fuse in a drivetrain system, an epicyclic gear system, and a method of operating a drivetrain system are provided. The epicyclic gear system includes a housing, a shaft configured to rotate relative to the housing, a sun gear being disposed concentric to the shaft, a plurality of planet gears disposed around the sun gear, a ring gear disposed around the plurality of planet gears, a carrier connecting the plurality of planet gears, and a torsional fuse defined by an interface between a first torsional fuse portion and a second torsional fuse portion, the torsional fuse being configured to allow rotation between the first torsional fuse portion and the second torsional fuse portion upon application of a threshold torque at the torsional fuse.
