 Abstract
This paper presents a calculus method for balancing optimization of rod pumping units with reverse scheme. The method establishes the constructive shape of the crank by imposing conditions that lead to a minimal motor moment, minimal reactions in the crank joints and minimum run time in a generator regime.

 Rezumat
Este prezentată o metodă de calcul pentru optimizarea echilibrării uniătaţilor de pompare cu schemă inversă. Metoda stabileşte forma constructivă a manivelei impunand condiţii care sa conducă la un moment motor minim, reacţiuni minime in articulaţia manivelei şi un timp de funcţionare minim in regim de generator.
