Belt (mechanical)Wikipedia

A belt is a loop of flexible material used to link two or more rotating shafts mechanically most often parallel. Belts may be used as a source of motion to transmit power efficiently or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys and the shafts need not be parallel.. In a two pulley system the belt can either drive the pulleys normally

Belt Tensionan overview ScienceDirect Topics

The drive for the drafting rollers is a rigid one (by gears) and the spindle is driven by a flexible drive (belt). The initial belt tensions on both sides of the spindle are the same while the machine is at rest. When the ring-spinning machine is started the belt tension in the forward direction increases and at the back it decreases enough
