This week’s episode explores the critical process of balancing rotating machinery to reduce unwanted vibrations and forces that can cause premature component failure. It begins by discussing static unbalance, which can be observed when a rotor consistently rests at a particular position, and explains how it can be corrected by adding or removing mass. The episode then addresses dynamic unbalance, occurring when a statically balanced rotor still wobbles due to uneven mass distribution, requiring corrections in multiple planes. Various techniques for analyzing and correcting unbalance are covered, including graphical, vector, and numerical methods. The episode also introduces different dynamic balancing machines—such as pivoted-cradle, nodal-point, and mechanical-compensation types—each designed to measure and correct unbalance in rotating systems.
