ABSTRACT:
A passive balance system for counterbalancing vibrations of a machine is taught. The passive balance system includes a support member adapted to be fixedly carried by the machine and a flexure assembly carried by the support member. The flexure assembly is in the form of at least one flat spring including connections along a central portion. The central portion is fixedly mounted to the support member, and an outer peripheral portion of the flat spring provides at least in part a movable counterbalance mass. The flexure assembly presents the counterbalance mass for movement in substantial alignment with a desired rectilinear component of vibration of the machine to counterbalance vibrations emanating therefrom. A vibration balanced machine having the passive balance system is also disclosed.
