Abstract of the Disclosure: Set out herein is a gearing mechanism wherein one gear of a smaller diameter engages in partial mesh another gear either in the form of a rack or a gear of a larger diameter. The pitch of the smaller diameter gear is made different than the pitch of the rack or the larger diameter gear thus achieving a pitch differential. To accommodate this in- equality in pitch the teeth of the smaller gears are radiused and the larger gear or rack may include rollers which engage these rounded teeth to accommodate the dif- ference in pitch by relative movement. In alternative implementations the smaller gear, rather than including teeth, may include a plurality of permanent magnets, once more distributed at a pitch different than a plurality of permanent magnets embedded in the larger gear or rack. The coercive force between the magnets can thus be used to transmit power at a gear ratio equal to the pitch differ- ential.
