The belt conveyors are the main type of continuous machine, which are widely used in various industries. The main units and elements of the belt conveyors are: a drive station with a drive drum, a tensioning station with a tension drum, a frame and a closed belt. The drive drum is used to transmit torque to the belt and to move it. The main requirements for the drive drums are as follows: ensuring adhesion to the belt; ratio of different diameters of drums with tape; the ratio of the number of tape pads to the drum diameter.
The geometrical diameters of the drums can be either the same along the length of the drums or different. The working surfaces of the drums can be of various shapes, as well as with or without lining.
The article presents, discusses and analyzes the design of the drive drums cylindrical, cylindrical-conical, barrel-shaped, barrel-shaped with tapers, with concave surfaces of the center and side parts, with cones towards the middle, cylindrical in the middle and end sections of linear and nonlinear shape. The geometries of the drums are provided upon manufacture.
The process of manufacturing components, assembling and finishing drums of various shapes, as well as cutting curved sections are complex technological operations.
The studies carried out made it possible to identify shortcomings in terms of belt displacement on drums with uneven increased wear of the belt along its width and a significant reduction in its resource.
To ensure the centering of the belt, a new design of the drive drum of the belt conveyor of a more rational design of a cylindrical shape with lateral screw-shaped cut surfaces is proposed.
