The methodology of testing rotational resistances of the rollers under the operation load

One of the components that affects the energy consumption of belt conveyors is the rotational resistance of the rollers. In real conditions, the roller is subjected to loads not only radial but also axial, resulting from its cooperation with the belt and the way of installation on the conveyor. Knowledge of these resistances is important not only in the design of conveyors, but also in the improvement and search for new structural solutions of the rollers. The article presents an innovative stand dedicated to the study of rotational resistance of the rollers under operating load, its research capabilities and the results of preliminary tests.
