Adjustable mass eccentric for multi-amplitude vibratory mechanism for compactor and system and method thereof

A method comprising:

• providing a rotatable shaft of a vibratory mechanism of a vibratory roller;
• and
• providing an adjustable mass eccentric along the rotatable shaft of the vibratory mechanism of the vibratory roller,
• wherein the adjustable mass eccentric includes:
• a body,
• an internal cavity defined by the body such that the body surrounds the internal cavity, and
• a filler material provided in the internal cavity,
• wherein the internal cavity has a first section, a second section, and a third section between the first section and the second section,
• wherein the first section defines a first area in a cross-sectional view of the body, the second section defines a second area in the cross-sectional view of the body, and the third section defines a third area in the cross-sectional view of the body, the first and second areas being greater than the third area, and
• wherein the vibratory mechanism is configured to vibrate the vibratory roller at three or more individual vibration amplitudes based on rotational control of the rotatable shaft and selective placement of the filler material in the first section or in the second section of the internal cavity.

An adjustable mass eccentric for a compactor comprising:

• a body;
• an eccentric lobe extending from a side of the body;
• and
• an internal cavity defined by the body such that the body completely surrounds the internal cavity,
• wherein the internal cavity includes:
• a first section,
• a second section, and
• a third section between the first section and the second section, the third section defining a volume less than respective volumes of the first section and the second section,
• wherein the first section and the second section taper toward the third section, and
• wherein the eccentric lobe is arranged closer to the second section than the first section and the third section.
