ABSTRACT:
A fixed ratio mechanical drive employing the tractive affect of rollers under pressure to transmit torque between co-axial members, including a means of obtaining the improved tractive engagement between rolling surfaces. The drive includes a first shaft in rolling contact with a number of equally spaced apart rollers on offset pins hinged in a second shaft, the improved traction being obtained by causing the rollers to rotate within a helicoidal component housed in a segmental locating ring having opposed conical shoulders co-operating with an adjacent ring and sleeve maintained under axial spring pressure resulting in tractive engagement between the helicoidal component, rollers and the first shaft.
