Claim 0:
1. A self-locking non-backdrivable gear system, comprising:
a. a self-lubricating gearbox, a primary motor input and a drive shaft, said primary motor input adapted to cause rotation of said self-lubricating gearbox about the axis of said drive shaft, said primary motor input;
b. said self-lubricating gearbox comprising:
i. an input gear mounted around said drive shaft and positioned in rotational engagement with said primary motor input;
ii. a plate and seal configuration mounted to said input gear and configured for sealing components within said input gear to allow the internal self-lubrication of said gearbox through a volume of lubricant;
iii. a locking gear rotatably mounted relative to the input gear, whereby said locking gear rotates with said input gear and also rotates about its own mounting axis;
iv. an output gear rotatably mounted relative to the input gear and further including an output shaft adapted for mounting to said drive shaft, said output gear has a first predetermined number of gear teeth in meshing engagement with said planet locking gear;
v. a fixed gear fixedly mounted around said output shaft and positioned adjacent to said output gear, said fixed gear has a second predetermined number of gear teeth in meshing engagement with said locking gear wherein said first predetermined number and said second predetermined number are different; and
vi. wherein said fixed and output gears comprise respective diameters configured to enable said fixed and output gear teeth to meshingly engaging with said locking gear,
vii. whereby rotation of said primary motor input causes rotation of said input gear which causes rotation of said locking gear which causes rotation of said output gear which causes rotation of said drive shaft, and whereby in the absence of rotation of said input gear a rotational force applied to said output gear forces the aligned said fixed and output gear teeth to lock said locking gear in place.
