ABSTRACT:
A dynamic rotational counterbalance structure includes a discoid balance body having a groove or race formed in an outer circumferential surface of the body. A plurality of movable weights such as spherical weights are positoined in the groove along with a lubricating and noise damping fluid. The groove is closed by an outer circumferential band. At least two of the balance structures are affixed coaxially on a rotatably member to be balanced. During rotation of the member so balanced, the weights shift circumferentially to offset unbalancing forces which influence the rotating member.
