At present, China's backbone gear manufacturing companies and research institutes represented by Shanghai Automotive Gear Plant and Shaanxi Fast Company complete automotive gears, motorcycle gears, construction machinery gear drives, agricultural machinery gears, industrial gear transmissions, and high-speed heavy loads. The introduction and digestion of various products such as gears, special dedicated gear transmissions, and gear-specific equipment have enabled China's gear transmission manufacturing industry to achieve leapfrog development in the past decade.
First of all, the manual transmissions for automobiles (including heavy, medium, light, and micro), gearboxes for cars, gears for motorcycles, shift gears for construction machinery, and supporting for large and medium-sized agricultural machinery transmissions have basically been based on domestic production and basically satisfied Supporting needs of the main engine plant, and there are already some gear parts export or gearbox export. In the automotive automatic transmission, it is still controlled by imported products.
Secondly, in terms of vehicle drive axles, active and passive spiral bevel gears, bevel gears and wheel reducers, most of them can meet domestic needs. The drive axle and bevel gear industry, represented by Dongfeng Bridge, is undergoing integration and development and has seen rapid development.
Thirdly, in the field of industrial general gearboxes, the entry of a group of wholly foreign-owned enterprises such as SEW has activated the China General Motors Transmission Corporation as the representative. In terms of product serialization, modularization, quality and technical level, there have been rapid advances in the last five years. The development has formed 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.
Fourthly, in terms of high-speed and heavy-duty gear transmission manufacturing, China has Nanjing Gaojing Gear Co., Ltd. (Nanjing High Speed ​​Gearbox Factory), Chongqing Gearbox Factory, Hangzhou Advance Gearbox Group, Zhengzhou Machinery Research Institute, and Luoyang Zhonghe Gearbox Co., Ltd. Machine company, Shenyang mine reducer company represented by the company. In the process of the introduction of 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, special, special wheel drive, such as non-circular gears, plastic gears, powder metallurgy gears, small modulus gears, etc., China has not formed a leading enterprise at present, the technical potential of the company has yet to play.
Sixth, gear-specific equipment, private enterprises have developed rapidly in the past five years, and state-owned enterprises have been slow to develop. Most of the state-owned gear and gear equipment manufacturers have made slower progress in the equipment reliability index, resulting in the majority of the gear industry's dominant finishing equipment still being imported. The hopes of localization of some gear enterprise equipment include: worm wheel grinding machine of Qinchuan Machine Tool Plant; CNC machine tool of Chongqing Machine Tool Plant and Nanjing No. 2 aircraft engineer; successful development of spiral bevel gear grinding machine tool; The batch supply of bevel gear cutting machine tools; Hangzhou Tianchen precision gear inspection tools, measuring tools, fixtures; Great Wall Lubricating Oil services to the gear industry lubrication market. All these have made our gear industry see the hope of independent innovation and independent development.
