Abstract
A self-locking non-backdrivable gear system in one embodiment includes an input spur gear mounted to a drive shaft, the input spur gear positioned in meshing engagement with a ring gear on which is mounted at least one planet locking gear which rotates with the ring gear and rotates on its own mounting. The planet locking gear meshes with a fixed spur gear and an output spur gear connected to a bi-rotational load bearing device. The fixed and output gears have different number of teeth and will lock in place with the planet gear should a rotational force be applied to the load bearing device in the absence of a rotational force at the drive shaft.
