Abstract.

The authors set and solve one of the important tasks concerning the conveyer transport systems: to  evaluate an average service life for the belt conveyor roller depending on different types of the roller carriage and, consequently, to estimate the conveyor line reliability.

As opposite to other studies, the author present calculations of the service life for the belt conveyor roller with taking into account loads on the roller bearing caused by dynamic efforts and the  weight motions on the conveyor line, and belt snaking. 

As a result of the study, a diagram was constructed showing dependence between the average conveyor roller service life and belt speed for different designs of the belt conveyors.

Analysis of the results permits to state that the roller service life depends on the linear load, conveyor parameters, granular composition of the transported weights, and roller carriage type and parameters, and the higher is the belt speed of the considered roller carriage types the shorter is average service life of the rollers. At the belt speed changed up to certain values, the roller service life is slightly longer for the suspended roller carriages than for the stiff roller carriages, and the roller service life is longer for the suspended roller carriages than for the cushioned roller carriages. At the same time, service life is essentially longer for the suspended cushioned roller carriages and cushioned roller carriages than for the suspended roller carriages and stiff roller carriages. In addition, at values of the belt speed higher than certain values for all considered roller carriage types the roller service life can be dramatically reduced by resonances caused by vibrations of the belt due to the motion of the lumps.

The findings can be applied in the mining, metallurgical and building industries.
