ABSTRACT:
An eccentric shaft assembly for a vibratory roller utilizes a cylindrical tubular shaft that considerably reduces the weight of the assembly, decreases substantially oscillatory shaft deflection during rotation and thereby improves bearing and seal life. The eccentric weights are mounted on the interior of the tubular shaft, thereby simplifying manufacture and providing a smoother operation.
