The core components of the chain conveyor transmission device include a driving wheel, a driven wheel, a chain, a tensioning device, etc. The drive wheel is usually installed at one end of the conveyor and is driven by a motor to drive the chain to rotate. The driven wheel is installed at the other end of the conveyor, and the material is transported through the chain. The chain forms a closed ring between the drive wheel and the driven wheel, and each link of the chain meshes with the Gear teeth, ensuring a smooth transmission of the chain. The function of the tensioning device is to maintain the tension of the chain, prevent the chain from loosening during operation, affecting the conveying effect.
