The purpose of research is to determine the optimal design parameters of the hinged connection of the sectional screw working body, as well as to determine the impact of these parameters on the performance of this mechanism The object of research is the processes of transportation of bulk materials along curvilinear routes by flexible articulated screw conveyors. The subject of the research is hinged-section screw working bodies and their parameters. The method of calculation of hinged connection of screw sectional working body is offered in the work. Calculations and analysis of changes in the efficiency of the hinge mechanism depending on its basic design parameters, such as the ratio of the radii of the ball and the cylindrical sleeve at the point of contact, the angle of deviation of the hinge axes, the angle of the conical surface of the hole. Graphic dependences are constructed on the basis of theoretical researches. Results: The optimal design parameters of this structure are established, and the influence of these parameters on operational characteristics is determined.
