| 摘要 |
The invention relates to a belt conveyor comprising a revolving conveyor bel t (1, 1'), carrying rollers (2, 2') which are positioned between the upper strand (3) and the lower strand (4, 4') of the conveyor belt (1), a drive device and a power- transmitting unit (5, 5') for moving the conveyor belt (1). Damage to the surface of the conveyor belt of the belt conveyor by the power-transmitting device is largely excluded by th e fact that for power transmission a pair of elements (6, 6', 7) is provided for which cooperate in a positive-fit and in that the one element (6, 6') is assigned to the power- transmitting device (5, 5') and the other element (7) to the conveyor belt (1).
