Abstract
An 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.

An eccentric weight system for a vibratory mechanism, the eccentric weight system comprising:
- 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 defining a first axis of rotation of the shaft;
- and
- an eccentric weight supported by the first shaft and having a center of mass that is offset from the first axis of rotation, the eccentric weight being 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.
A vibratory compactor comprising:
- a compacting mechanism having a first vertical support member and a second vertical support member;
- a first shaft rotatably supported at a first end by a first shaft support on the first vertical support member and rotatably supported at a second end by a second shaft support on the second vertical support member, the first and second shaft supports defining a first axis of rotation of the shaft;
- and
- an eccentric weight supported by the first shaft and having a center of mass that is offset from the first axis of rotation, the eccentric weight being 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.
A method for producing vibration in a vibratory mechanism comprising:
- supporting rotatably a first end of a first shaft with a first shaft support on a first vertical support member;
- supporting rotatably a second end of the first shaft with a second shaft support on a second vertical support member, the first and second shaft supports defining a first axis of rotation of the shaft;
- supporting an eccentric weight with the first shaft, the eccentric weight having a center of mass that is offset from the first axis of rotation and wherein 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;
- and
- rotating the first shaft about the first axis of rotation.
