Abstract

A belt drive is provided which includes a circulating belt (8) which is driven by at least one drive element (9) and which drives at least one driven element (10). At least one first tensioning device (20) acts upon the belt (8) in the slack strand and at least one second tensioning device acts in the tightened strand. To prevent or reduce jumps and/or transverse oscillations of the belt (8), the second device (21) guides the belt (8) and at least one third device (22) which is arranged radially inside the belt drive, which is suitable, optionally, limits deviations of the belt (8). The second device (30, 40, 50, 60, 70, 80, 90, 100) also tensions the belt (8) in such a manner that it is subjected to a force (F1) which is smaller than the force (F2) which is oriented counter thereto during the operation of the belt (8) on the second tensioning device (30, 40, 50, 60, 70, 80, 90, 100).
