Belt drive is also called "belt drive". It is a type of mechanical transmission. It consists of one or more belts tightly wrapped around two pulleys. The two pulleys are mounted on the driving shaft and the driven shaft respectively. The friction between the belt and the two pulleys is used to transmit motion and power. Belt rotation can be used for long-distance transmission between two shafts (working machine and power machine). Because the belt is elastic, it can mitigate impact, reduce vibration, and ensure smooth transmission, but it cannot maintain a strict transmission ratio. When the transmission parts encounter obstacles or are overloaded, the belt will slip on the pulley, thus preventing damage to the parts. Belt drive is simple and easy to operate, low in cost, simple to maintain, and easy to disassemble and replace. Belt drive has the following characteristics: (1) Simple structure, low manufacturing cost, and easy installation and maintenance. (2) The belt is elastic and can mitigate impact and vibration, so it runs smoothly and has low noise during operation. (3) The elastic sliding of the belt on the pulley changes with the load, so the transmission ratio is inaccurate. However, when overloaded, it can slip. Therefore, it can prevent damage to other transmission parts.
