In the “13th five year plan” for the development of China’s gear industry (hereinafter referred to as the “plan”) previously published, the development objectives of the gear industry during the “13th five year plan” were put forward.
First, the innovation capacity has been significantly enhanced. China’s gear industry has initially established a technological innovation system with sustained innovation capability, breaking through a number of core technologies, forming some international famous brands and patents, and the standard system is basically in line with the international standards, creating two to three multinational enterprises with international competitiveness, with significantly improved innovation capability and international competitiveness.
Second, the supporting capacity and export capacity of gear products have been comprehensively improved. The manufacturing capacity of high-end gear products has been greatly improved, and the product performance and quality are generally close to the international advanced level. The gear products basically meet the needs of domestic key equipment and large-scale engineering supporting. The proportion of high-end gear products such as industrial robot precision reducer and TBM heavy-duty reducer of shield machine has reached about 50%. The export volume of high-end gear products increased significantly, the import volume decreased significantly, and the import-export trade deficit decreased by about 60%.
Third, the industrial structure has been comprehensively optimized. Promote the adjustment of gear industry structure, 2-3 enterprises enter the top 10 gear world enterprises, a group of “specialized, refined, special and new” enterprises develop steadily; improve the industrial concentration, and form two gear industry accumulation areas with strong international competitiveness.
Fourth, remarkable achievements have been made in energy saving and material saving. Advanced technologies such as gear near net forming, dry cutting, superhard machining and ultra precision machining have been popularized and applied. The utilization rate of gear materials has been increased by 20%, the production efficiency has been increased by 30%, the energy consumption has been greatly reduced, and the power loss of gear transmission has been reduced by 15%.
At the same time, it is clear in the plan that during the 13th Five Year Plan period, China’s gear industry will conquer some core technologies and break through a number of key products. For example, we have conquered the core technologies such as long-life and high-efficiency manufacturing technology of, lightweight design and manufacturing technology of gear transmission device, surface modification technology of gear; we have made great progress in long-life and anti fatigue manufacturing technology of gear, vibration reduction and noise reduction technology of gear transmission, intelligent diagnosis and maintenance technology of gear transmission device operation state, and remanufacturing technology of gear; we have made great progress in near net shape green system of gear Manufacturing technology and super hard dry cutting technology have been improved and widely used. In addition, it is also necessary to use 6000 kW ~ 10000 kW high-speed high-power gear speed regulating device for the industrial robot precision reducer, high-speed locomotive gear transmission device with the speed ≥ 350 km / h, shield machine and TBM heavy-duty reducer, gear transmission device with the linear speed ≥ 300 m / s, and military helicopter gear transmission device with the service life ≥ 10000 h for the million kilowatt nuclear power and ultra supercritical thermal power units A number of key products, such as the automatic transmission of power unit, automobile, large open pit excavator and hydraulic transmission of dump truck, are imported to different extent; in terms of hybrid power and pure electric vehicle automatic transmission, high-end gear transmission for aerospace, etc., their performance should reach or approach the international advanced level, and basically meet the domestic demand.
According to the plan, we should formulate specific catch-up plans and technical roadmap against the world’s advanced enterprises and products; for important products, gear Association will organize the establishment of industry university research and application alliance to jointly tackle key problems and achieve breakthroughs.
During the 13th Five Year Plan period, China’s gear industry will continue to promote integration, transformation and upgrading of the two, establish R & D service platform, implement quality and brand strategy, implement gear standardization strategy, implement gear steel quality improvement project, and strive to solve the financing problems of small and medium-sized micro enterprises.
