A static balance (sometimes called a force balance ) occurs when the inertial axis of a rotating mass is displaced from and parallel to the axis of rotation. Static unbalances can occur more frequently in disk-shaped rotors because the thin geometric profile of the disk allows for an uneven distribution of mass with an inertial axis that is nearly parallel to the axis of rotation. Only one plane receives balance correction. WebBefore attempting to field balance a rotor, follow these basic steps: Perform a vibration analysis on the machine.
