ABSTRACT:
A drive mechanism for a paper machine controlled deflection roll or the like having a tubular roll shell driven by a ring gear with driving pinions driving the ring gear and each of the pinions mounted on support shafts with the support shafts carrying planetary gears driven by a sun gear. The sun gear is carried on a power input shaft mounted in vertical slides. The planetary gears are horizontal of the sun gear so that the sun gear can shift and be self-positionable to equalize the load on the gear teeth as the sun gear drives the planetary gears with a thrust bearing on the shaft and helical teeth between the sun gear and the planetary gears.
