Toothed chain technology innovation drives high-end equipment upgrades, ushering in new opportunities for the global industrial chain

Introduction, as the global manufacturing industry moves towards high precision and high reliability, the toothed chain (Silent Chain), as the core component in the field of precision transmission, is ushering in the "two-wheel drive" of technological breakthroughs and market demand. Recently, many domestic and foreign companies have released a new generation of toothed chain products, promoting its application in new energy vehicles, industrial robots, aerospace and other fields, which has attracted widespread attention in the industry. First, the toothed chain: The "invisible champion" toothed chain in the field of precision transmission is a chain that realizes power transmission through special meshing teeth. Compared with traditional roller chains, it has significant advantages such as low noise, high transmission efficiency, and wear resistance. The structure is made up of multiple pieces of precision stamped chain plates, which can effectively reduce vibration and energy loss during the transmission process through the precise meshing of the tooth shape and the sprocket. "Under high-speed, heavy-duty and high-precision working conditions, the performance advantages of the tooth shape chain are particularly outstanding." Experts from the China Machinery General Parts Industry Association said, "Especially in the fields of new energy vehicle motor transmission systems and high-end CNC machine tools, the tooth shape chain is gradually replacing the traditional transmission scheme." Second, technological innovation: a double breakthrough in materials and processes. In recent years, tooth chain technology has continued to iterate: material upgrades: the use of high-strength alloy steel, carbon fiber composites, etc., to improve the fatigue life and impact resistance of the chain; process innovation: the introduction of advanced manufacturing technologies such as laser cutting and nano-coating, so that the accuracy of the chain plate reaches the micron level and further reduces the friction coefficient; intelligent design: through simulation and simulation to optimize the tooth shape parameters, to achieve a transmission efficiency increase of more than 15%. For example, a well-known German transmission company recently launched the "ultra-quiet tooth chain" series, which can maintain stable performance under extreme temperatures through adaptive lubrication technology, and has won orders from many European car companies. 3. Market demand surges, and the industrial chain accelerates the layout. According to Global Industry Analysts, the global toothed chain market size will exceed 4.20 billion US dollars in 2023, with a compound annual growth rate of 6.8%. As the world's largest manufacturing base, China is becoming the core engine for the growth of toothed chains: New energy vehicles: The lightweight and silent demand for transmission parts in electric drive systems promotes the rapid increase in the penetration rate of toothed chains; Industrial automation: Robot joints, intelligent logistics equipment and other fields are in strong demand; Energy equipment: Wind power gearboxes, oil drilling equipment and other scenarios application expansion. Domestic enterprises such as Hangzhou Donghua and Suzhou Global Chain Drive have accelerated the layout of high-end production lines and gradually broken the monopoly of foreign brands in the high-end market. IV. Challenges and Opportunities: Domestic substitution accelerates. Despite significant technological progress, our country's toothed chain industry still faces challenges: high-end steel and precision processing equipment rely on imports; international giants (such as Japan's Tatsumoto and BorgWarner of the United States) occupy more than 60% of the global market share. However, with policy support and coordinated innovation in the industrial chain, the process of domestic substitution accelerates. In 2023, the Ministry of Industry and Information Technology will include "high-performance transmission components" in the "Catalogue of Industrial Basic Innovation and Development" to further promote the standardization and large-scale development of the industry. V. Expert point of view, Li Ming, a professor at the Department of Mechanical Engineering of Tsinghua University, pointed out: "The precision and intelligence of toothed chains are irreversible. In the future, enterprises need to focus on customized solutions and cooperate with upstream and downstream to take the initiative in global competition. "Conclusion, from" follow-up "to" and run ", the breakthrough of toothed chain technology is not only the epitome of the upgrading of our country's high-end equipment manufacturing industry, but also reflects the urgent need for precision basic components in the global industrial chain. With the deepening of the new round of scientific and technological revolution, this" silent "chain is quietly promoting the operation efficiency of the industrial world to a new height.
