Carrying and tractive belts loading of a multi-drive conveyor in case of accidental sliding deviations of electric motor drives

Abstract

The paper contains the results of theoretical studies of loading parameters of carrying and tractive belts of a multidrive belt conveyor in case of accidental sliding deviations of electric motor drives. The direct effect of a random combination of sliding deviations on the working life value of the carrying belt is shown. The justification for taking into account the actual parameters of belt loading cycles when calculating their working life during the process of designing multidrive belt conveyor within each combination of sliding deviations is given. The paper demonstrates inconsistency of the approach regulating the determination of the skewness ratio of loading cycles as a value inverse to the drives traction factor.
