BALANCING OF TECHNOLOGICAL MACHINE ROTORS Podgornyj Yu. I. , D.Sc.

Marksa, Novosibirsk, 630073, Russian Federation Abstract Lengthy rotors of production machines need balancing. The paper presents a method of balancing a production machine rotor on the example of a two-shaft continuous mixer. A design model as a rotor space system is described. An imbalance plan reduced to two flat systems as well as values of corrective imbalances is presented. Conditions for full rotor balancing are revealed. The highest and lowest deviations of correcting imbalance values from the nominal values (in percentage) for various precision degrees of the manufacture of working shaft components are also found. It is revealed that with a reduction in the manufacture precision of working shaft components an expected value of the correcting imbalance deviation increases and can reach 75%.
