The new method for balancing an assembly of rotating elements with variable dynamics

The study presents an analysis of both passive and active balancing systems, with active balancing systems considered more effective, especially for devices with variable rotational speeds and imbalance dynamics. The focus was placed on the balancing mechanism of a centrifuge used for mineral particle sedimentation studies. The analysis of available solutions revealed that ready-made electronic and mechanical systems were not suitable for direct adaptation, necessitating the development of a new solution. An innovative active balancing mechanism was designed, based on two cooperating discs, one of which can move relative to the other along two axes. The mechanism works by detecting centrifugal force and automatically adjusting the relative position of the discs, bringing the rotating system to a balanced position. The built prototype confirmed the effectiveness of the solution up to 800 rpm. The developed design has been submitted for patent protection.
