Abstract: A rotation transfer device comprising a first rotating element, a second rotating element, and a rotation coupling mechanism wherein the rotation transfer device transfers the rotational force from the first rotation element to the second rotation element and also allows free and independent rotational precession of the second rotating element with respect to the first rotating element. Thus, the device allows for bi-directional transfer of rotational power from the power gear to the driven gear, and allows free and independent rotational precession of the driven gear with respect to the power gear. Therefore, the device can be utilized in a variety of applications, most notably, the device can be used to provide a differential function to vehicles. The device can also be used for non-vehicular applications where uni-directional or bi-directional rotation transfer and slip or freewheeling are required.
