Interpretation of the development status of China's gear transmission manufacturing industry
Introduction: With the development of the national economy, under the guidance of relevant state ministries and agencies, China's gear transmission manufacturing industry has developed by leaps and bounds. Gears and their gear products are important basic components of mechanical equipment. The main transmission components of most mechanical complete sets are gear transmissions. China's gear industry has developed rapidly during the 10th Five-Year Plan period: in 2005, the annual output value of the gear industry increased from 24 billion yuan in 2000 to 68.3 billion yuan, with a compound annual growth rate of 23.27%, which has become the largest of China's mechanical infrastructure parts. Industry. In terms of market demand and production scale, China's gear industry has surpassed Italy in the global ranking, ranking fourth in the world. China's gear industry applications are mainly: First of all, car manual gearbox (including heavy, medium, light, micro), car gearbox, motorcycle gear, engineering machinery shift gearbox, large and medium-sized agricultural machinery variable speed transmission, has been basically based on domestic production, basically satisfied The main equipment factory needs, and already has some gear parts outlet or gearbox outlet. In the case of automotive automatic transmissions, it is still controlled by imported products. Secondly, most of the vehicle drive axles, active and passive spiral bevel gears, straight bevel gears and wheel reducers can meet the domestic supporting needs. The drive axle and bevel gear industry represented by the East Windmill Bridge is being integrated and reorganized, and has seen the hope of rapid development. Third, in the field of industrial general-purpose gearboxes, the entry of a number of foreign-owned enterprises such as SEW has activated the representative of China's industrial general-purpose gearbox enterprises. In terms of product serialization, modularization, quality and technical level, the past five years have made rapid progress. The development has formed a fierce competition with international brands. Some of the 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 heavy-duty gear transmission manufacturing, China has Nanjing High-precision Gear Co., Ltd. (Nanjing High-speed Gearbox Factory), Chongqing Gearbox Factory, Hangzhou Forward Gearbox Group, Zhengzhou Machinery Research Institute, Luoyang Zhongzhong Deceleration The company represented by the machine company and Shenyang Mine 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, special and special wheel transmission, such as non-circular gears, plastic gears, powder metallurgy gears, small modulus gears, etc., China has not formed a leading enterprise at present, and the technological potential of the enterprise has yet to be played. Sixth, in terms of gear special equipment, private enterprises have developed rapidly in the past five years, and state-owned enterprises have developed relatively slowly. The equipment reliability index of most state-owned gear equipment manufacturing enterprises has progressed slowly, resulting in most of the leading finishing equipment in the gear industry still being imported. The hopes of localization of some gear enterprises are: worm wheel grinding machine of Qinchuan Machine Tool Plant; CNC machine tool of Chongqing Machine Tool Plant and Nanjing Second Captain; successful development of spiral bevel gear grinding machine; Tianjin Yuanhao CNC spiral Batch supply of bevel gear cutting machine; Hangzhou Tianchen precision gear inspection tool, measuring tool, fixture; Great Wall lubricants to the lubrication industry of the gear industry. These have made China's gear industry see the hope of independent innovation and independent development. Ceramic tiles is widely used in bathroom and kitchen walls. It made by 850℃ sintering temperture, so it can do marble,wood,cloth,carpet,cement,rock texture on the tiles surface. Also the water absorption is 10% so that it can be paved directly with cement,not necessary to use the special tiles adhesive . It can save your cost.
