the drive pulley (drive end). The Drive pulley pulls the belt rather than pushing it. Running the belt in this direction allows for pretty high loads. This is because the belt is pulled tight onto the drive pulley during operation, which eliminates slippage between the drive pulley and the belt and allows the full transfer of

Two or more pulleys are coupled with a belt in tension in a belt drive system. One pulley (driving pulley) drives the belt, while the other pulley is driven by the belt (driven pulley). A belt transmits power between at least two pulleys in a belt drive. Because the speed of belt drives is often lowered, the smaller of the two pulleys is used ...

The horse power required at the drive of a belt conveyor pulley is derived from the following formula: H.P = Te . V. Where. Te is the effective tension in the belt in N. V = velocity of the belt in m/s. The required effective tension Te on the driving pulley of a belt conveyor is obtained by adding up all the resistances.
