Визначення перехідного процесу бокового сходження стрічки з барабана конвеєра з незначною криволінійністю

A belt conveyor has been investigated in this work. The effect of the angle of the belt axis relative to the drum axis on the lateral runout of the belt was considered. The influence of the belt speed, the load at the point of contact of the belt with the generator drum, the curvature of the generator drum, and the linear mass of the belt on the lateral runout of the belt were also examined. The friction coefficient of the belt sliding on the rollers in the running section of the belt on the drum, the belt tension at the point of running on the drum were investigated. It was established that lateral runout always occurs in the absence of perpendicularity of the belt axis relative to the drum axis. The belt speed during lateral runout is maximum at the beginning of the transition process and decreases as the displacement increases. During lateral runout of the belt in the zone of its contact with the generator drum, tangential and normal loads occur. The stationary state is achieved when the belt axis becomes perpendicular to the drum axis. Tangential loads in the absence of slippage do not depend on normal loads and are caused by the non-perpendicular location of the belt axis relative to the drum axis. Tangential load is proportional to the lateral displacement of the belt. The transient process of belt slippage on a drum with a slight curvature of the generator is described by an equation corresponding to an aperiodic link of the first order. This study make it possible to determine optimal parameters when designing a system for automatic belt centering on a drum with a curved generatrix. Thus, in the development of the end station of a belt conveyor (Patent of Ukraine No. 98378), a hydraulic pump NSH-10E was used. The magnitude of the drum curvature is limited by the resulting unevenness of belt tension across the width, as well as the possibility of belt slippage, and significantly depends on the stiffness of the belt
