초록

Disclosed is a symmetrical traction drive that utilizes multi-diameter rollers having traction surfaces for transferring rotational mechanical energy between the shaft and a transfer gear. Multi-diameter rollers are mounted in carriers disposed between two substantially symmetrical ring gears. Sloped traction surfaces of the ring gears mate with inner traction surfaces on both sides of the multi-diameter rollers. Since force is applied to the inner traction surfaces on both sides of the multi-diameter rollers, forces are substantially equalized on each s...
