The operation of a toothed belt involves the interaction of these teeth with the grooves on the pulleys. When the driving pulley rotates, the belt moves in unison, causing the driven pulley to rotate at a specific ratio, which is determined by the size of the pulleys and the number of teeth on the belt. This precise coordination allows for accurate synchronization in applications like engine timing, where even a slight delay can result in serious mechanical issues.
