Abstract:
A method of balancing a body of revolution in a balancing machine, the balancing machine including an adjustment unit for resetting the position of compensation masses, the method comprising:(a) placing the compensation masses in respective zero positions, wherein imbalance vectors produced by the compensation masses cancel each other out;(b) measuring a system imbalance vector V1 in terms of its magnitude and direction, the system being defined as comprising the balancing machine and the body of revolution;(c) resetting at least one of the compensation masses by shifting said at least one compensation mass through a desired angle or by changing a distance between said at least one compensation mass and an axis about which said at least one compensation mass turns, thereby producing an additional imbalance having a calibration imbalance vector V2;(d) measuring said angle or the change in said distance;(e) measuring an overall imbalance vector V3 in terms of its magnitude and direction;(f) calculating said calibration imbalance vector V2 by subtracting said system imbalance vector V1 from said overall imbalance vector V3, as follows:V2=V3-V1; and(g) moving the compensation masses out of said respective zero positions such that the system imbalance vector V1 is compensated for.
