DRIVING DRUM, DEFLECTING DRUM, AND TENSIONING DRUM FOR BELT CONVEYORS

摘要

The invention relates to the design of driving, deflecting, and tensioning drums for conveyor belts, comprising a one-piece drum jacket or a drum jacket (1) comprising a center drum body (10) and two bearing pieces (11, 12) attached to both sides of the center drum body. All three components of the drum jacket (1) are provided with flanges on the sides facing each other and screwed together at said flanges. Each of the two bearing pieces (11, 12) has an annular bearing seat for rolling-element bearings on the outside. Each of the two rolling-element bearings is accommodated on the outside by a bearing shield (3, 4), wherein the one bearing is a fixed bearing and the other bearing is a floating bearing. In a first embodiment, a direct drive (2), the rotor of which directly drives the drum jacket (1), is provided as a drive. The important advantage provided by the design of the drums according to the invention is that high stability is achieved due to the large diameters of the drum jackets (1) and the large bearings used together with the bearing shields (3, 4).
