How to rationally design conveyor chain equipment

　　The production line factory is slowly moving in the direction of automation. The conveying equipment has been widely used. It also has many classifications. Among these conveying equipments, there are many types of equipment specifications!

　　Although the chain conveyor has a small running speed, it has a large transmission torque and a large transmission power. Therefore, the driving device is generally composed of a motor reduction unit, and the driving device drives the shaft to rotate to complete the operation of the conveyor chain and the transportation of the object.

　　The chain transport equipment basically uses the chain as the main body of the load. Because the length of the chain is large, the chain pitch will be elongated due to the wear of the chain during use. Therefore, the chain transport equipment must plan the tensioning equipment, which can ensure that the chain wear is increased and then the two chains are removed, and the transporter can work normally to increase its service life.

　　The structure of the tensioning device in the chain conveyor device has a spiral tensioning structure, a spring tensioning structure and a weight tensioning structure. Because the chain tension of the chain conveyor equipment is generally large, when selecting the screw tensioning structure, it must be noted that the tensioning screw is subjected to compressive stress without being subjected to tensile stress to satisfy the requirements of strength and rigidity, especially when tensioning. This is especially true when the shaft support of the structure is cast iron.

　　The chain as the main body of the chain conveyor equipment should also be selected reasonably. Generally, the chain standard is selected according to the power curve according to the running speed and the chain transmission power. Other methods of chain standard selection are still based on empirical comparison.
