In between the discs are rollers, which differ the ratio and transfer electricity from 1 facet to the opposite. In the event the rollers' axes are perpendicular towards the axis from the discs, the helpful diameter is identical for the input discs and the output discs, leading to a 1:1 generate ratio. For other ratios, the rollers are rotated alongside the surfaces in the discs so that they are in contact with the discs at factors with distinctive diameters, leading to a push ratio of a little something besides one:one.[fifteen]
