About Us

Nanjing Hansen High speed gearbox Manufacturing Co., Ltd. is a large enterprise specializing in the production of high-speed and heavy-duty Gearboxes. It is located at No. 34, Huatang Road, Honglan Industrial Concentration Zone, Lishui District, Nanjing. In line with the enterprise spirit of "integrity, pragmatism, innovation and refinement", the company has introduced gear design concepts, calculation programs and manufacturing process technologies from gear companies in Germany and the United States. Through the company's research and development and innovation, it has formed advanced design concepts and manufacturing processes, especially in the design and manufacturing technologies of high-speed, high-precision and heavy-duty gearboxes. It has always maintained a leading position in China and reached the same level as developed countries in Europe and the United States, laying a solid technical foundation for the development of the company. The company has set up a special technical center, with 6 professor-level senior engineers and 3 experts enjoying State Council subsidies. It has established cooperative relations with many domestic and foreign universities and scientific research institutions, established a complete set of quality control systems, passed the ISO9001 quality system certification, and was the first in China to adopt ISO 1328 international standards and AGMA API613 standards. The company has imported various advanced gear processing machine tools, international advanced equipment such as measurement, testing, and testing, as well as complete sets of heat treatment equipment from world-renowned companies such as the United States, Germany, Switzerland, and Austria. Among them, more than ten high-efficiency CNC forming gear grinding machines imported from Germany, more than ten large multifunctional heat treatment furnaces imported from Austria, 5 high-speed gear hobbing machines imported from Germany, 16 machining centers of various types, 2 three-coordinate measuring instruments, and 3 gear measuring instruments. The gearboxes produced by the company have been carefully designed, accurately calculated, and strictly tested and tested. They are known for their low vibration, low noise, small size, strong load-bearing capacity, and high safety and reliability. They are well-known at home and abroad and have been successfully applied to chemical industry, centrifugal high-speed blowers, steam turbines, compressors, building materials, metallurgy, power generation, mining, energy, aerospace, new energy vehicle test benches, and scientific research test benches of major domestic colleges and universities, and enjoy a high reputation in the domestic high-speed and heavy-duty gearbox market.At present, the company's products have formed more than a dozen large series, which are convenient for users to select and can be specially designed according to the needs of users. Product processing range: hardened gear diameter can reach 6000mm, modulus can reach 50, and the accuracy can reach 5 or above (ISO1328), up to 3. The maximum pitch circle speed is 176m/s, the maximum speed is 80000rpm, the maximum power is 63000kW, and the maximum torque is 8300kN/m. The spiral bevel gear has a diameter of 1200mm and a precision of 5. The carburizing furnace introduced by the company with the German Siemens control system can carburize gears with a diameter of less than 6000mm, the carburizing layer depth can reach 8~9mm, and the tooth surface hardness reaches HRC58~63.

The company has introduced some famous experts from the United States and Germany to participate in the management, which has laid a solid foundation for the company's development into the world, making the company at the world's leading level in technology, equipment, product performance, etc. For many years, the company has adhered to the rigorous style of "responsibility in place, do it right the first time" and the concept of "being responsible to users and society is being responsible to ourselves", and has successively provided gearbox products for many large, medium and small domestic enterprises. The company is also actively exploring the international market, and its products are exported to dozens of countries and regions such as the United States, Europe, Southeast Asia, and the Middle East. The company's main products include: high-speed Speed Increasers, high-speed reducers, gearboxes for high-speed test benches, high-power and high-speed ratio gearboxes, metallurgical rod and wire rolling mill gearboxes, Vertical mill reducers, Edge drive reducers, petrochemical gearboxes, general gearboxes, Planetary gearboxes, modular gearboxes, crane gearboxes, worm gear screw lifts, precision gears, various non-Standard gearboxes and Gear Spare Parts, etc. The products cover new energy vehicles, blowers, steam turbines, compressors, building materials, metallurgy, power generation, chemical industry, mining, lifting, energy, aerospace, test benches and many other fields, and have a great advantage in the domestic high-speed and heavy-load gearbox and non-standard gearbox markets.

Our company adheres to the principle of "quality first, customer first" and is committed to providing users with high-quality products and satisfactory services. Our products, especially the gearboxes for blowers, steam turbines, compressors, centrifugal and axial fans, gas power generation, aviation test benches, new energy vehicle test benches, various high-speed test benches and high-speed pumps, have won widespread praise and recognition from customers for their excellent performance such as high reliability, high stability, high efficiency, low noise, low vibration, energy saving and environmental protection.
