Recently, with the rapid development of industrial production, industrial chains, as key transmission components in various types of mechanical equipment, have received widespread attention for their use and maintenance precautions. The stable operation of industrial chains is directly related to production efficiency and safety. However, equipment failures and even safety accidents caused by ignoring relevant key points often occur, which rings the alarm bell for enterprise production. In the industrial field, chains are widely used in transportation and transmission, such as material transportation in automated production lines and power transmission in machine tools. However, many companies have many problems in the use of industrial chains. A large manufacturing factory once suffered from long-term lack of lubrication of the chain, resulting in severe wear of the chain links, which suddenly broke under high-speed operation, not only causing the production line to stop for up to 8 hours, but also direct economic losses of hundreds of thousands of yuan, and almost causing harm to the on-site operators. Industry experts pointed out that the installation of industrial chains is crucial. Before installation, the compatibility of the chain and sprocket must be strictly checked to ensure that the chain model, pitch and sprocket parameters are fully matched to avoid abnormal operation due to specifications not meeting the requirements. At the same time, to ensure the installation accuracy of the sprocket, the axes of the two sprockets should be kept parallel, and the deviation should be controlled within a very small range, otherwise the chain is prone to unilateral force, tooth skipping and other problems, which greatly shortens the service life. Monitoring during operation is also indispensable. It is strictly forbidden to operate the chain when it exceeds the rated load and speed, especially at the moment of starting. Excessive impact load can easily cause the chain to break. Enterprises should monitor the operating status of the chain in real time. Once abnormal phenomena such as "tooth climbing" and "tooth skipping" are found, they must be stopped immediately for investigation. Possible reasons include sprocket wear, chain pitch elongation or insufficient tension. Daily maintenance is the key to ensuring the performance of industrial chains. Regular lubrication can significantly reduce the friction between the chain and the sprocket and reduce wear. Enterprises should select suitable lubricants according to the working environment and frequency of use of the chain, and formulate scientific lubrication cycles. At the same time, the tension of the chain should be checked regularly. Too tight or too loose is not conducive to the normal operation of the chain. Too tight will increase the load on the equipment, and too loose will easily cause tooth skipping and chain derailment. In addition, safety protection measures must be in place. Set up guardrails in the chain operation area to prevent people from accidentally contacting the running chain; provide professional training for operators to familiarize them with the correct operation and maintenance methods of the chain and improve safety awareness. Once a chain failure occurs, it should be handled strictly in accordance with the emergency plan to avoid secondary accidents caused by improper operation. At present, relevant industry associations have begun to organize a series of training and publicity activities to popularize the correct use and maintenance knowledge of industrial chains to enterprises. At the same time, government regulatory authorities have also increased their inspections on enterprise safety production, urged enterprises to fulfill their main responsibilities, and strengthened the management of key equipment such as industrial chains to ensure safe and efficient production. Although the industrial chain is small, it is related to the "lifeline" of industrial production. Only by paying attention to its use and maintenance precautions can enterprises effectively improve production efficiency, reduce safety risks, and lay a solid foundation for high-quality industrial development.
