Friction Influence on the Accuracy of the Rotors Automatic Balance

Abstract:

In the given paper the influence of friction forces in the bearing on the accuracy of automatic balancing unbalanced rotors by pendular automatic balance devices is considered. Magnitude of residual offset of a rotor–pendulums system depending on the friction forces is received, that allows defining residual vibration of the mechanism.
