Abstract
A wobble plate drive system may include a stator having a central axis, an upper surface perpendicular to the central axis, and a plurality of stator teeth disposed on the upper surface. The system may further include a wobble plate having a wobble axis disposed at a non-zero angle relative to the central axis, a lower wobble surface perpendicular to the wobble axis, and an upper wobble surface perpendicular to the wobble axis. A plurality of lower wobble teeth may be disposed on the lower wobble surface and a plurality of upper wobble teeth may be disposed on the upper wobble surface. The system may include an output gear having an output axis substantially aligned with the central axis and a lower surface perpendicular to the output axis. A plurality of output teeth may be disposed on the lower surface. The wobble plate may be configured to rotate as it nutates around the stator.
