Abstract
Abstract An irrigation tower structure is provided including support and drive wheels for supporting and driving the tower from and over ground to be irrigated. The tower has a driven shaft journalled therefrom and wheel driving shafts journalled therefrom. A plurality of numerically high ratio sets of meshed gears drivingly connect the driven shaft to the wheel driving shafts and each set of meshed gears includes a first gear mounted on a support shaft therefor and having a plurality of rollers generally paralleling, supported from and spaced equally about and radially outwardly from the support shaft and a second gear mounted on a support shaft therefor including an outer peripheral portion defining a plurality of outwardly opening notches formed in and spaced about the outer peripheral portion, the first gear of each set being meshed with the second gear of the corresponding set with the rollers of each first gear successively engageable in the notches spaced about the outer peripheral portion of the corresponding second gear.
