Development of mathematical model of excitation of high-frequency axial vibrations of the case of combined with the swinging unit gear

In the article the reasons increased axial vibroloads the combined pump including pumping up screwcentrifugal and basic gear a step are researched. The developed mathematical model is presented. It is carried out calculation of axial forces with the purpose of research of influence of axial forces on bearing unit of the pump, operating in gear step.
