ABSTRACT:
A biaxial idler comprising a flexible and resilient toroid and a frame. The frame has the capability of allowing the toroid to rotate independently both about the toroid's annular axis and about a straight axis substantially orthogonal to that annular axis. The toroid's outer perimeter can thus roll in a direction parallel to the toroid's straight axis. This biaxial idler is useful in continuously variable transmissions, because it provides a simple and rugged method of transmitting torque continuously across a wide range of varying transmission ratios while suffering minimal frictive losses and wear.
