Abstract.

From the design theory, it is known that the more is inclination of the side roller the higher is a conveyor output and the more is resistance of the belt motion on the carrying rollers. Thus, a task is to determine optimal parameters for the conveyor belt troughs ensuring maximal linear load.

In this article, basing on the established dependence between resistance force of the belt motion in the conveyor with deep belt fluting and tray parameters and weight properties a problem of optimal design of the conveyor line with three- and five-roller supports is set and solved.

Maximal linear load was assumed as an efficiency criterion, and a coefficient of  resistance of the belt motion on the carrying rollers induced by the weight deformation was assumed as restriction factor. Such parameters as angle of the side rollers inclination and width of the tray bottom were assumed as variables.

The problem was solved by probing the variables. For each variable parameter a maximal linear load and, correspondingly, a coefficient of  resistance of the belt motion on the carrying rollers induced by the weight deformation were determined and registered in a table. Further, a maximal value of the linear load and, correspondingly, a minimal coefficient of resistance of the belt motion induced by the weight deformation  were chosen from this table.

The findings shows that optimal inclination of the side rollers in the conveyors with the deep fluting which ensures maximal output for the conveyor is: 40⁰ for the three- and 24°, 40° for the five-roller supports.

Besides, optimal inclination of the side rollers in the conveyors with the deep fluting and three- and five-roller supports is as much as twice of the optimal inclination of the side rollers in the conventional conveyors.
