ABSTRACT:
A traction transmission mechanism comprising toric shaped inner and outer race elements, a series of pairs of transmission rollers arranged between the race elements, and drive shaft and driven shaft or other structure constructively cooperating with the mechanism, to furnish an output force, with the transmission incorporating various load equalization structure to furnish substantially floating characteristics to one of the supported race elements, to provide radial and tangential shifting to the roller elements as arranged between the race elements, and to adjust one of the race elements, or more specifically one of its pair of races, towards or away from each other, to change the traction force generated within the transmission mechanism during its functioning.
