Abstract:
An eccentric assembly for oscillating a compacting drum of a compacting machine includes: a central disk rotatably mounted to the compacting drum to have an axis disposed in juxtaposition with an axis of the compacting drum, and configured to be rotatably driven by a motor; a pair of opposed eccentric shafts, each axis of which is disposed equidistantly from the center of the axis of the central disk, the eccentric shafts being rotatably mounted to the compacting drum such that the three axes of the central disk and the eccentric shafts are in the same plane; and yoke disposed between the central disk and the two eccentric shafts in such a manner as to be connected to the central disk and the two eccentric shafts, respectively, by means of three connecting members. One end of each of the connecting members is rotatably coupled to different positions of the yoke, and the other end thereof is fixed to a corresponding one of time central disk and the two eccentric shafts such that the two eccentric shafts rotate synchronously by the rotation of the central disk.
