Types of belts for belt drives - tec-science

The increased power transmission combined with the high flexibility of the cogged narrow V-belts results in a relatively space-saving design of such belt drives. In addition, the lower flexural stiffness reduces the deformation energy required when the belt runs around the pulleys, which increases the efficiency compared to the classic V-belt.

How does a belt drive work? - tec-science

In belt drives, power is transmitted between at least two pulleys by a belt. One pulley drives the belt ( driving pulley) and the other pulley is driven by the belt ( driven pulley ). In belt drives, the speed is often reduced, so that in these cases the smaller of the two pulleys is the driving pulley. Figure: Operating principle of a belt drive.
