The analysis results of longitudinal and cross bends of screws of rotational pumps is carried out. Check of the offered model of cross-bending of the screw both taking into account, and without thread is executed. The interrelation of bend of the screw and decrease in the moment of inertia of its cross-section is revealed and the model of calculation of the screw on stability in pitch considering these parameters is received.
