ABSTRACT:
An eccentric planetary traction drive transmission which includes at least two planetary rollers, sun roller member, and a carrier member. One of the planetary rollers is flexible and is positioned between and in contact with an outer ring member and the sun roller member. Rotation of either the outer ring member or the sun roller member wedges the flexible planetary roller within a convergent wedge gap which squeezes the flexible planetary roller between the outer ring member and the sun roll member. Friction between the flexible planetary roller, the sun roller member, and the outer ring member transmits rotational motion and torque between the outer ring member and the sun roller member. The other at least one supporting planetary roller is a supporting roller which supports the sun roller member and the carrier member. A plurality of bearings supports the sun roller member within the outer ring member and the at least one supporting planetary roller.
