Abstract
An anti-friction worm-wheel assembly wherein the anti-friction elements are ollers carried by the worm element. The rollers sequentially move through grooves in the edge surface of the wheel element to transmit drive forces from one element to the other. Aims of the invention are to achieve rolling contact of the anti-friction elements on the groove surfaces, relatively high load-handling capability, and a relatively simple low cost structure.
