Abstract: This invention relates to an apparatus for dynamically and constantly balancing rotating objects while they are in motion. Such an apparatus can be applied to balancing wheels of automobiles or trucks or can be applied to balancing the shafts of rotating machinery. The basic concept is to attach a fixture that supports a system of weights to the rotating object. Said weights are free to move relative to the rotating object in an orbit concentric to the axis of rotation of said rotating object. Under the influence of the forces generated by rotation of the rotating object above its critical speed, the system of weights take a configuration that opposes and partially cancels the imbalance of the rotating object. This invention also relates to a method of making the inventive apparatus by concentrically placing the annular hoop on the mounting fixture and fixing the hoop in place by use of counter-rotating, high-speed rotary press.
