    摘要： A vibratory compactor that generates vibrations by rotation of eccentric masses is provided, which includes an inner eccentric rod positioned inside a roller drum of the vibratory compactor and provided with a rack formed on one side of the inner eccentric rod, a pinion engaged with the rack, a variable eccentric weight engaged with the pinion so that a distance between the variable eccentric weight and a rotation axis of the inner eccentric rod is changed as the pinion is rotated, and an outer eccentric tube including a hole formed thereon to guide movement of the rack back and forth and a support fixture formed thereon to fix a shaft of the pinion so that the pinion is rotated in engagement with the rack, wherein when the inner eccentric rod moves back and forth, the pinion that is engaged with the rack is rotated as much as the movement of the rack, and as a position of the variable eccentric weight is changed, an amplitude of vibration of the roller drum is changed.

    摘要： The present disclosure presents an eccentric assembly for a compaction machine comprising: an outer eccentric member that is longitudinally elongated cylinder shaped and has a partial longitudinal opening through the length; an inner eccentric member that is longitudinally elongated cylinder shaped and has a partial longitudinal opening through the length and rotatably connected inside of said outer eccentric member so that the inner eccentric member can rotate with respect to the outer eccentric member around the same axis of rotation.
