  • ECCENTRIC WEIGHT SYSTEM WITH REDUCED ROTATIONAL INERTIA FOR VIBRATORY COMPACTOR
    Publication number: 20200087870
    Abstract: An eccentric weight system for a vibratory mechanism is provided. The eccentric weight system includes a first shaft rotatably supported at a first end by a first shaft support and rotatably supported at a second end by a second shaft support. The first and second shaft supports define a first axis of rotation of the shaft. An eccentric weight is supported by the first shaft and has a center of mass that is offset from the first axis of rotation. The eccentric weight is supported so as to be rotatable about a second axis of rotation relative to the first shaft with the second axis of rotation being offset from the first axis of rotation.
