Abstract

Purpose. In the study is necessary: 1) to justify aligning drums of a new design of belt conveyors; 2) to develop a method for calculating and determining the rational design parameters of drums depending on the technical parameters of the conveyor belt (the length of the conveyor, belt width, the performance of the conveyor, the diameter of the drive and tension drums, etc.); 3) to carry out pilot studies of efficiency conveyor belt in a production environment in order to determine the magnitude of dynamic loads and a comparative evaluation of the effectiveness of the centering ability of conventional and new designs of drums. Methodology. To substantiate the effectiveness of the centering ability of the drums of a new design by the authors developed a mathematical model of interaction of the tape with the drum. Mathematical simulation of tape reels with new design comes to drawing up a differential equation of the belt based on the dynamic component and restoring force. This model allowed us to estimate the movement of the tape in the transverse direction based on the calculated additional dynamic loads and forces on the investigated centering a conveyor belt with given specifications. For the first time the technique of calculating and determining the rational parameters of the drums, which allows determining the design parameters of the centering portions, depending on the mechanical properties and geometric parameters of the tape. Findings. With the help of mathematical modeling the scientifically substantiated effect of centering the ability of the new design of the drum, which ensures stable tape running along the longitudinal axis of the conveyor. The authors made the following conclusions: 1) the mathematical model of interaction with the new belt design of the drum, which allowed to describe the belt in the transverse direction in view of additional dynamic loads and renewable power was developed; 2) the method of calculation and determination of parameters of rational design of new barrels, which allows to determine the design parameters of centering areas was proposed ; 3) the experimental studies of conveyor belt with given technical parameters in a production environment, which allowed to determine the dynamic loads during the acceleration conveyor, as well as optimize the start time to reflect these pressures was conducted. Thus, stationary conveyors with increasing acceleration of time from 10-15 to 24 with dynamic loads can be reduced from the level of 20-35% to 9-10% of the nominal. Comparative evaluation of experimental and calculated values of the magnitude of dynamic loads makes the difference to 4%. Originality. For the first time offered the theoretical tools that justify the effective performance of a new design of the drums of belt conveyors, as well as allow us to determine their rational design parameters. Practical value. New designs of drums, their method of calculation and constructive parameters can be used in the design of new and modernization of existing belt conveyors that will minimize unplanned downtime and improve the durability of the belt.
