Abstract
The V-belt drive has a V-belt (R), revolving endlessly around a drive pulley (A) and at least one driven pulley (C) and a back chucking roller (D) is associated with the V-belt on the slack side (R1). The back chucking roller (D) is preceded in the belt travel direction (RL) by a profiled idler pulley (E), and both rollers (D, E) form a clamping unit (SE) that is subjected to clamping force action and acts near the driven pulley (C). In every position of the clamping unit (SE) the entry and exit point (G1 and G2, respectively) of the V-belt (R) at the profiled idler pulley (E) are located before, in the belt travel direction (RL), or at best coincide with the entry point (K1 and K2, respectively) of the back chucking roller (D).
