Abstract
The present invention is directed to a self-locking non-backdrivable gear system. The gear system may comprise a primary motor input and gear box. The primary motor input is for rotation of the gearbox about the axis of a drive shaft. The gearbox may comprise an input ring gear, one or more locking gears, fixed gear, and output gear. In operation, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the locking gear which causes rotation of the output gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, a rotational force applied to the output gear causes the gear teeth on the fixed and output gears to lock the gear in place.
