ABSTRACT:
In a traction roller transmission wherein a traction ring surrounds a sun roller with planetary traction rollers arranged in the space between, and in engagement with, the sun roller and the traction ring, a tapered ball screw structure is so associated with at least one of the sun roller and traction ring that a torque transmitted through the transmission causes the tapered ball screw structure to expand radially for forcing the planetary traction rollers into engagement with the traction ring and the sun roller.
