In modern technology, long inter-bearing rotors are widely used. These are augers with stiffer suspension - the propellers of rotor-screw machines. Screw augers - the working bodies of snowplows. The static and momentary imbalance of the support rotor in this case leads to a serious imbalance in the operation of all mechanisms. There is a need for vibration and noise reduction when operating machines equipped with long screw rotors. The basic rule in the design and calculation of long screw rotors is to ensure their balanced operation. The tasks of the presented surveys are the derivation of the equations of dynamics of long inter-bearing rotors in order to reduce vibration loads on their supports.
