Abstract
A curvilinear gear system and method for transferring force and speed through a wide range of angles is disclosed. The system can optionally incorporate curvilinear U joints to increase effective range of angles to tailor the system to specific applications. The system includes complimentary gear heads, one of which is a curvilinear gear such as a hemispherical gear. A method of using the gear systems in a transmission apparatus is also disclosed.

A curvilinear gear system comprising:
- a first gear having a curvilinear hemispherical surface and a flat surface opposite the hemispherical surface;
- a first shaft attached to the flat surface at an axis of rotation for the first gear;
- a second gear having a second curvilinear hemispherical surface and a second flat surface opposite the second hemispherical surface;
- a second shaft attached to the second flat surface at an axis of rotation for the second gear wherein the hemispherical surfaces of the gears interact to transmit torque and speed.
