At present, the average person in China owns a car. In developed countries, one person owns a car. China's car industry has a broad market. Therefore, the prospects of automotive transmissions are promising. China needs to drive 10,000 cars and 10,000 sets of bevel gears every year. Axial load, single and double drive axles are in short supply, while foreign single drive axle axle loads have been reached. In contrast, there is a clear gap. The industrial universal gear industry universal gear reducer is a standardized, serialized and versatile reducer for industrial complete sets of equipment and production lines.
Nanjing High Precision Gear Co., Ltd. has developed a series of hardened surface modular gear reducers with international standards. In addition, many famous foreign gear manufacturers have entered China, bringing advanced technology and products. They are looking at the huge Chinese market.
The involute gear reducer accounts for the largest proportion of the universal reducer. In addition, China's circular gear reducer can be said to be unique in the world. The special gear box for industrial special gear industry is specially designed according to the requirements of the mainframe, and has the characteristics of small batch and multiple varieties. The high-speed gear and gear unit high-speed gear has a linear speed range of one, a high-speed shaft speed of one, and a transmission power of one.
The high-speed gearbox developed by Nanjing Gaojing Gear Co., Ltd., Shenyang Blower Factory and Zhengzhou Machinery Research Institute has approached or reached the advanced level of foreign countries. Both air gears and marine gears require high reliability. Through the introduction of technology and the introduction of equipment, China's manufacturing capacity and level have been greatly improved. Zhongnan Transmission Machinery Factory and Chongqing Gearbox Co., Ltd. are representatives in this regard. Chongqing Gearbox Co., Ltd. sells marine gearboxes.
Gears for metallurgy, coal mine and cement industry In recent years, the domestic ratio of gear products imported from metallurgical equipment has reached more than the above. The special gears for mining machinery designed and developed by China have reached the level of the world's major coal mining countries in the century. In addition, gear transmission has a wide range of applications in conveyors, hoists and other equipment. The mill reducer is bulky, low in speed and heavy in load. At present, China can produce a power range of one, and basically has the ability to design and manufacture a large-scale central transmission mill reducer.
In addition to the above three kinds of large-scale gear transmission, gear couplings, gear pumps, etc. also play an important role in mechanical transmission, and there is also a broad market space in China. Although China's gear transmission technology has a very Great development, the quality and level of gear products have been greatly improved, but compared with the world's advanced level, there is still a considerable gap. The author believes that China's gear manufacturing industry should pay attention to solving the following problems. Improve the design level and form the ability of independent development For a long time, China's gear design and strength calculations have always used static experience design methods.
Although I also use computers to do some calculations and drawing work, I have been at a low level. A little better is just an imitation of foreign products. During the meshing process, the tooth surfaces slide with each other, and friction, wear and heat deformation are dynamic processes.
Modern design techniques such as comprehensive and dynamic simulation should be adopted, and international advanced standards should be actively adopted to make the gear design more scientific and more realistic. Adopt advanced processing technology. On the one hand, we must transform and refine some gear processing machine tools through electronic technology and information technology. On the other hand, we must introduce digestion and develop a new generation of gear machine tools or machining centers. High-precision, high-efficiency, energy-saving, and environmentally-friendly green manufacturing technology is the direction of gear processing. The company's latest high-speed worm wheel grinding machine achieves high precision and high-efficiency machining with high grinding speed. China's Qinchuan Machine Tool Plant and the former Changsha Railway Institute have developed spiral bevel gear cutting machines. Gear Company has recently introduced a high-speed dry cutting gear hobbing machine capable of machining gears with diameters.

Air to Air Waste Heat Recovery Equipment
through and exchange energy(heat-recovering system and exhaust heat recovery system). It can separate fresh air and exhaust air completely, avoided
any solvent transmission. The two air cross and counter flow to the exchanger, then fresh
air and exhaust air exchange energy through the metal plate,
collisions between particles in the hot inner region transfer energy to particle
s in the cooler outer region and realize to recycle energy from exhaust air.
