At present, my country's backbone gear manufacturing enterprises and research institutes represented by Shanghai Automobile Gear General Factory and Shaanxi Fast Company have completed automobile gears, motorcycle gears, construction machinery gear transmission, agricultural machinery gears, industrial gear transmissions and high-speed heavy-duty gears. The technology introduction and digestion of gears, special special gear transmission, gear special equipment and other products have 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 shifting gearboxes, and large and medium-sized agricultural machinery variable-speed transmissions have basically been produced in China, basically satisfying The main engine factory needs to support, and some gear parts or gearboxes have been exported. In the aspect of automobile automatic transmission, it is still controlled by imported products.

Secondly, in terms of vehicle drive axles, active and passive spiral bevel gears, spur bevel gears and wheel side reducers, most of them can meet domestic supporting needs. The drive axle and bevel gear industry represented by Dongfeng Axle is undergoing integration, reorganization and development, and has seen the hope of rapid development.

Third, in the field of industrial general gearboxes, the entry of a number of foreign-owned enterprises such as SEW has activated the Chinese industrial general gearbox enterprises as representatives. In the last five years, there has been rapid progress in product serialization, modularization, quality and technical level. The development of the company has formed a 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, my country has Nanjing High Precision Gear Co., Ltd. (Nanjing High-speed Gearbox Factory), Chongqing Gearbox Factory, Hangzhou Advance Gearbox Group, Zhengzhou Machinery Research Institute, Luoyang Zhongzhong Reducer Enterprises represented by Machinery Company and Shenyang Mining Reducer Company. In the process of introducing technology, these enterprises have made significant contributions to the development of large-scale complete sets of equipment and the development of the shipbuilding industry in China.

Fifth, in terms of special and special wheel transmission, such as non-circular gears, plastic gears, powder metallurgy gears, small module gears, etc., there is currently no leading enterprise in my country, and the technical potential of the enterprise has yet to be realized.

Sixth, in terms of gear special equipment, private enterprises have developed rapidly in the past five years, while state-owned enterprises have developed relatively slowly. The equipment reliability indicators of most state-owned gear equipment manufacturing enterprises are progressing slowly, so that most of the leading finishing equipment in the gear industry is still mainly imported. The hope of localization of equipment of some gear enterprises mainly includes: worm grinding wheel gear grinding machine of Qinchuan Machine Tool Factory; CNC machine tools of Chongqing Machine Tool Factory and Nanjing No. 2 Captain; the successful development of spiral bevel gear grinding machine tools; Tianjin Yuanhao Company CNC Spiral Bulk supply of bevel gear cutting machine tools; Hangzhou Tianchen precision gear inspection tools, measuring tools, fixtures; Great Wall Lubricant's lubrication market services for the gear industry. All these make my country's gear industry see the hope of independent innovation and independent development.
