Abstract
A drive, preferably a gate drive with a belt transmission encompassing a drive pulley and an output pulley. According to the invention the drive pulley consists of at least one cylinder with inwardly tapering flanges at its ends. A round belt, rope or similar serves as a drive agent, which is wound a number of times around the cylinder. The return strand of the round belt, rope or similar can be held continuously under tension.

A gate drive with a belt transmission comprising a drive pulley and an output pulley, the drive pulley including at least one cylinder which has inwardly tapering flanges at its ends, a round belt wound around the cylinder a number of times as a drive element, a return strand of the round belt held continuously under tension, and a carriage with an articulation point which can be moved back and forth by a load strand, said carriage movement being essentially perpendicular to a direction of movement of the load strand between the drive pulley and the output pulley.
A gate drive with a belt transmission, comprising a drive pulley and an output pulley, the drive pulley including at least one cylinder, a round belt wound around the cylinder a number of times as a drive element, a return strand of the round belt held continuously under tension, and a carriage with an articulation point which is moved back and forth by a load strand, the direction of movement of the carriage being substantially perpendicular to the direction of movement of the load strand and the return strand between the drive pulley and the output pulley, such that movement of the carriage causes one of the load strand and the return strand to be deflected depending on a direction of rotation of said drive pulley.
