Prerequisites for the Creation of Energy-Conserving Constructions of Tubular Belt Conveyors

A description of different constructions of tubular belt conveyors with spherically shaped rollers is given. Through use of the functional relationships between the tribotechnical assemblies of the conveyors, the energy losses caused by friction and wear of the service elements are determined, their contribution to rolling and sliding friction established, and the significance of each technical and economic criterion of the relative competitive advantage of alternative variants of tubular belt conveyors determined.
