Through anti-fatigue and long-life manufacturing technology, it solves the long-term problem of short life span, poor reliability, and heavy structural weight in the Chinese gear industry, with a view to realizing a whole new industry-driven development driven by high-end gear products. This was on February 24th. The common aspirations of participants from the “China Gear Industry Development Conference†held in Tianjin. During the conference, nearly 100 key enterprises in China's gear industry, including Beijing Beidai, CITIC Heavy Industries, Tianjin Tianhai Synchronous, Stellar Technology, Ningbo Dongli, Hangzhou Jiepai, etc., jointly initiated and jointly united with Beijing University of Technology, Henan University of Science and Technology, and raw materials and machine tools. The "China Gear Industry Alliance," which is jointly established by industry chain-related companies and research institutes such as cutters, gauges, and oil products, has made substantial progress after more than six months of preparation.
In this regard, Lu Xi, Deputy Director of the Industrial Policy Department of the Ministry of Industry and Information Technology at the China Gear Industry Development Conference pointed out in his speech that "China Gear Industry Alliance" will be a key component of China's equipment manufacturing industry (gears, bearings, hydraulics, pneumatics, seals, and The first industry alliance in the fasteners industry, its establishment marks the confidence and courage of the Chinese gear industry to overcome high-performance gears, break through high-end products, adjust the industrial structure, and promote industrial upgrading. It is also a joint initiative to build innovative industries. .
Parts and components represented by gears are not only the basic industries of China's equipment manufacturing industry, but also are important foundations in various fields of national economic construction. As a part that transmits motion and power in a mechanical transmission, a gear is both a main transmission part and a moving part. It is a key part in many high-end mechanical equipment fields such as automobiles and machine tools, and usually determines the main functions of the overall equipment. It is understood that as one of the three major markets in the gear industry, vehicle gears account for 62% of the total gear market, of which automotive gears account for 62% of the market share of vehicle gears. In other words, the gears used in automobiles account for nearly 40% of the entire gear market, showing the importance of gears for the automotive industry.
Zhao Zhenye, an academician of the Chinese Academy of Engineering, introduced in his speech at the conference that the main failure modes of gears are fatigue including bending fatigue and contact fatigue. For a long time, the short life, poor reliability, and heavy structure have become the three major problems that restrict the development and safe use of China's gear industry, and "formed" manufacturing is the main reason for the formation of three major problems.
Academician Zhao Zhenye and his team, through more than 20 years of research and practice, integrated design, materials, and manufacturing techniques to form a set of theory and system methods for anti-fatigue and long-life manufacturing technology with stress-free concentration and dual use of Chinese characteristics. Through the practice and application in aviation and other fields, the feasibility of fatigue-resistant gear manufacturing theory is proved.
Through the new concepts of anti-fatigue machining, surface composite hardening technology and surface layer composite modification technology, the life of gears can reach tens to hundreds of times under the original “forming†processing state, which greatly improves the key parts of gears. Reliability, while significantly reducing the weight of gear components, has become a realistic way for China to independently manufacture high-end gears.
The reporter noted that the development of advanced AMT, DCT, CVT and multi-speed AT automatic transmission assembly, as well as the development of energy-saving and environmentally friendly automatic transmission key components, high-precision low noise long-life large and medium spiral bevel gear, high precision automotive gear Such as the "12th Five-Year" period of the gear industry focus on the development of projects and projects; and anti-fatigue long-life high-end gear manufacturing technology, is China's gear industry to achieve these major projects and key projects a predictable breakthrough. Zhang Wei, general manager of Beijing North Teeth Co., Ltd., said in an interview with reporters at the meeting that the gear industry needs to be led by autonomous core technologies that can realize industrialization, gather industry-researched resources across the industry, jointly innovate, and overcome common industrial technologies. Long-term heavy equipment gear transmissions rely on the import passive situation.
Delegates said that the whole industry must unite and give full play to the wisdom and strength of the government, enterprises, and scientific research. Driven by high-end gear products, the entire industry chain will be synchronized and innovated. In order to revitalize China’s equipment manufacturing industry, China’s construction will be completed as soon as possible. Become a strong country in the gear industry and work hard.
