coinciding with the angle of the heavy spot relative to the zero mark on the rotor. Since the rotor 2 receives an oscillatory motion in

axial direction, it interacts with both tools 3 and 4 alternately during each rotation of its rotation, which leads to the removal of metal from the ends in two planes

correction from diametrically opposite sides, i.e. provides elimination of the moment component of the imbalance. After its removal, tool 4 from position 1 is relocated

In position 11, and on the vibration exciter 6, the control excitation is supplied with the parameters of the static component of the dysbapance. In this case, the rotor 2 interacts with tools 3 and 4 alternately during each revolution and metal is removed from the ends in two planes of correction on one side of the rotor, i.e. eliminates the static component

rotor imbalance

2. The alternate elimination of moment and static components is continued until reaching

One of the tools installed at the rotor ends, in the balancing process, is rearranged in the diametrically opposite direction relative to the rotor axis.
