ABSTRACT:
A drive belt for a linear motion drive system in which a plurality of drive belts are helically disposed and rotated about a driven element to axially advance the element along its axis. The belts include a pair of spaced legs which resiliently abut legs of adjacent belts to equally space the belts about the periphery of the driven element. The legs also are adapted to accommodate changes in diameter of the driven element.
