Abstract
The article examines the screw modules of technological machines that feed materials under pressure and move loads in the vertical direction to various working bodies. The main disadvantage of these screw modules is low productivity due to the spiral movement of the material, with a significant deviation from the longitudinal axis of the screw module. The paper considers the possibility of increasing the operational performance of screw modules of technological machines by reducing the rotational component of the material movement. This goal is achieved by installing ribs on the inner surface of the module. The angle of ribs installation is determined by the kinematic and geometric parameters of the conveyor auger shaft and the properties of the supplied and moved loads. The results of theoretical studies show that correctly selected geometrical parameters of the ribs can increase the screw module productivity by 18 – 20%.
