Leap-forward Development of Gear Transmission Manufacturing Industry in China

At present, my country's backbone gear manufacturing enterprises and research institutes represented by Shanghai Automotive Gear Factory and Shaanxi Fast Company have completed automobile gears, motorcycle gears, engineering machinery gear transmissions, agricultural machinery gears, industrial gear transmissions and high-speed heavy The technology introduction and digestion of various products such as gears, special gear transmissions, and special gear equipment has enabled my country's gear transmission manufacturing industry to develop by leaps and bounds in the past ten years.

First of all, automobile manual gearboxes (including heavy, medium, light, and micro), car gearboxes, motorcycle gears, construction machinery shift gearboxes, and large and medium-sized agricultural machinery variable speed transmissions have basically been based on domestic production and basically met The supporting needs of the main engine factory, and some gear parts or gearboxes have been exported. In the automatic transmission of automobiles, it is still controlled by imported products.
Secondly, in the vehicle drive axle, active and passive spiral bevel gears, straight bevel gears and wheel reducers, most of them can meet the domestic supporting needs. The drive axle and bevel gear industry represented by Dongfeng axle are integrating and reorganizing and developing, and have seen the hope of rapid development.
Third, in the field of industrial general-purpose gearboxes, the entry of a number of wholly foreign-owned enterprises such as SEW has activated the Chinese industrial general-purpose gearbox market, represented by a large number of private industrial gearbox enterprises in Jiangsu and Zhejiang, in terms of product serialization, modularization, quality and technical level, there has been rapid development in the past five years, forming fierce competition with international brands. Some products produced by Chinese enterprises have reached the international level, and some products have been exported to Europe and the United States.
Fourth, in terms of high-speed and heavy-duty gear transmission manufacturing, China has enterprises represented by 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 Zhongzhong Reducer Company and Shenyang Mine Reducer Company. In the process of introducing technology, these enterprises have made great contributions to the development of China's large complete sets of equipment and shipbuilding industry.
Fifth, special, special gear transmission, such as non-circular gears, plastic gears, powder metallurgy gears, small modulus gears, etc., China has not formed a leading enterprise, the technical potential of enterprises has yet to be played.
Sixth, in terms of special gear equipment, private enterprises have developed rapidly in the past five years, while state-owned enterprises have developed relatively slowly. The equipment reliability index of most state-owned gear equipment manufacturing enterprises has made slow progress, resulting in most of the finishing equipment in the gear industry is still mainly imported.
