摘要： A variable-speed belt drive includes at least: two shafts that can be positioned in a substantially parallel manner; two variably interspaced flange pulleys, one driving, the other driven, one carried by one, the other by the other of the shafts, the pulleys being interconnected by the belt; a speed-variation device controlled by the action of the flanges of the driving pulley being brought together or interspaced; and elements for recalling the flanges in a close position. The speed-variation device is manually controlled and the shaft of the driven pulley is provided with at least one idler member having an outer peripheral surface mounted on the shaft in a freely rotating manner, and around which the belt can wind at least partially in the interspaced position of the flanges of the driven pulley, corresponding to the position with the smallest diameter for the winding of the belt around the shaft.
