Abstract
A drive system for a multi-roll leveler. The drive system is coupled to a set of upper work rolls of the leveler. Preferably, the lower, and not the upper set of work rolls provide the bending necessary to flatten the strip of material. The drive system employs a gearbox housing one or more gear trains adapted to rotationally drive the upper set of work rolls. A drive means is coupled to the gear train(s). When more than one gear train is used, the gear trains may drive an equal or unequal number of upper work rolls. The upper work rolls may be splined to better engage the gear train. Output shafts may be provided on the gear box to connect the gear train(s) to the work rolls. The drive system does not require the use of universal joints to drive the work rolls. When the upper and lower sets of work rolls are contacted with the strip of material, the driven rotation of the upper work rolls causes the strip of material to move through the leveler.
