Information

At present, the backbone gear manufacturing enterprises and research institutes represented by Shanghai Automotive Gear General Plant and Shaanxi Farst Company have completed the technical introduction and digestion of automobile gears, motorcycle gears, construction machinery gears, agricultural machinery gears, industrial gearboxes, high-speed and heavy-duty gears, special gears, gear equipment and other products, so as to make gear transmission in China. Moving manufacturing industry has developed by leaps and bounds in recent ten years.

Firstly, the automobile manual transmission (including heavy, medium, light and micro), car transmission, motorcycle gear, construction machinery transmission, large and medium-sized agricultural machinery transmission has been basically based on domestic production, basically meet the supporting needs of the main engine factory, and some gear parts or gearbox exports. In automobile automatic transmission, it is still controlled by imported products.

Secondly, in terms of vehicle driving axle, active and passive spiral bevel gears, spur bevel gears and wheel side reducers, most of them can meet the domestic supporting needs. Drive axle and bevel gear industry, represented by Dongfeng Windmill Bridge, are being integrated, restructured and developed, and have seen the hope of rapid development.

Thirdly, in the field of industrial general gearbox, SEW and other foreign wholly-owned enterprises have activated China's industrial general gearbox enterprises as representatives. In terms of product serialization, modularization, quality and technological level, there has been a rapid development in the last five years, forming a fierce competition with international brands. Some of the products produced by our enterprises have reached the international level, and some of them have been exported to Europe and America.

Fourth, in the manufacturing of high-speed and heavy-load gear transmission, China has Nanjing High-precision Gear Co., Ltd (Nanjing High-speed Gear Box Factory), Chongqing Gear Box Factory, Hangzhou Forward Gear Box Group, Zhengzhou Machinery Research Institute, Luoyang Heavy Reducer Company, Shenyang Mining Reducer Company as the representative enterprises. In the process of introducing technology, these enterprises have made great contributions to the development of large-scale complete sets of equipment and shipbuilding industry in China.

Fifth, special and special wheel transmission, such as non-circular gears, plastic gears, powder metallurgy gears, small module gears and so on, has not formed a leading enterprise in China, and the technical potential of the enterprise still needs to be developed.

Sixth, in terms of gear special equipment, private enterprises have developed rapidly in the past five years, while state-owned enterprises have developed slowly. The equipment reliability index of most state-owned gear equipment manufacturing enterprises has progressed slowly, which results in that most of the leading finishing equipment in the gear industry is still mainly imported. Hopes for localization of gear equipment in some gear enterprises include: Worm Grinding Machine of Qinchuan Machine Tool Factory; CNC Machine Tool of Chongqing Machine Tool Factory and Nanjing Machine Chief; Development of Spiral Bevel Gear Grinding Machine Tool; Mass Supply of CNC Spiral Bevel Gear Cutting Machine Tool of Tianjin Yuanhao Company; Hangzhou Tianchen Precision Gear Testing Tool, Measuring Tool and Fixture; Lubrication Market of Great Wall Lubricating Oil for Gear Service. All these make our gear industry see the hope of independent innovation and development.
