The idler pulley in a belt drive system is used to guide or route the belt, maintain proper tension, and reduce belt slack, ensuring efficient power transmission. It helps prevent belt slippage and vibration, contributing to the overall longevity and reliability of the belt-driven components. Additionally, the idler pulley allows for adjustments in belt routing without requiring changes to the existing drive layout.
