Belt drive has the characteristics of simple structure, stable transmission, buffering and vibration absorption, power transmission between large axle spacing and multi-axes, low cost, no need of lubrication, easy maintenance, and so on. It is widely used in modern mechanical transmission. The friction type belt transmits kinetic energy overload, slipping, low running noise, but the transmission ratio is not accurate (the sliding rate is less than 2%); The synchronous belt drive can ensure the transmission synchronization, but the absorption capacity of load change is slightly poor, and there is noise during high-speed operation. In addition to transmitting power, belt drive is also sometimes used for conveying materials and arranging parts.

The pulley with power drive will be called the drive pulley, and the rest will be called the idler pulley. There are two kinds of occasions for industrial application of transmission belt: in the factory, the material handling of conveying materials or objects in boxes or pallets, and the bulk material handling of conveying large quantities of materials or agricultural products (such as grain, salt, coal, ore, sand or overburden).

Drive belt, also known as conveyor belt, is the transmission medium in the drive belt system. The drive belt system is one of the drive systems. The system will include two or more pulleys with drive belts on it. The pulleys can rotate the drive belt without restriction. One or more pulleys will be powered to drive the drive belt and carry the material on the drive belt.
