Abstract

A high ratio traction drive transmission includes a sun roller, a traction ring, a plurality of traction planets in contact with the sun roller and the traction ring, at least one reaction roller in contact with at least one of the traction planets, and a carrier assembly coupled to at least one of the traction planets and the at least one reaction roller. The sun roller has a first longitudinal axis and the traction ring is aligned coaxially with a second longitudinal axis, wherein the first longitudinal axis is radially offset from the second longitudinal axis.
