Abstract (en)
[origin: WO2015165599A1] A drive system or support system, in particular for elevators, is described, comprising a belt pulley having a diameter of at least 70 mm and a drive belt or support belt which is curved around the belt pulley, wherein the drive belt or support belt comprises a cover layer (1), which is arranged on the lower side of the belt facing toward the belt pulley, and at least one tension layer (2), which is arranged directly above the cover layer; the cover layer is made of a polymeric material having elastic properties, the tension layer contains at least one fiber bundle which is almost unidirectional and which runs in the longitudinal direction of the belt, wherein certain relationships apply between the thickness of the cover layer, the thickness of the tension layer, the diameter of the belt pulley (4) and the Shore A hardness of the cover layer.
