  • Vibratory compaction system
    Patent number: 4350460
    Abstract: A vibratory compactor vehicle includes a roller drum provided with internal concentrically mounted eccentric weights which are rotated for imparting vibration to the drum. The weights are mounted upon concentric shafts of helical polygonal shape having mating, helically ribbed and grooved surfaces, whereby longitudinal movement of one of the shafts with respect to the other brings about relative rotation of the weights, thereby changing the amplitude of the resulting vibration.
