"11th five-year plan" and after a longer period of time, China will develop large-scale, clean and efficient power equipment. Million kilowatt nuclear power units, large hydro turbine and the pumped-storage unit, ultra supercritical thermal power unit, gas-steam combined cycle power plant and power generating winds are emphasis. Etc. More importantly, these industrial development is not only the market capacity and changes of metal processing techniques and methods or will bring a revolution.

Taken together, these industrial materials to the high strength, high temperature resistant, fight corrode, ultra-low temperature and lightweight direction, roll forming machine nonmetal materials, the proportion of composite materials increase gradually, While these areas of production technology and high degree of automation, mostly in various process, the net-shape forming the direction of development, many parts of shape for complex surface, These areas are increasingly demanding quality of equipment, the high reliability requirements of equipment provider, and follow-up service ability put forward higher requirement, These fields were also used in equipment, large capacity and high parameter of high-power direction, and gradually ultra high temperature conditions, ehv, high-speed development of extreme conditions. Service in these fields, high-grade nc machine tools with large and heavy, precision, high speed, intelligent, flexible, etc.

With the highest attention by the wind generator gearbox, for example, gear box is an important mechanical components, its main function is to rotor in the function of wind power generator and its to get the corresponding speed. Due to the high installation, etc FengKouChu wilderness, beach, irregular change, change to the wind load and strong wind, the impact of heat and cold, and extreme temperature has the influence, together with the natural environment of traffic inconvenience, gear box installed in the narrow space, once the malfunction, very difficult, so to repair its reliability and service life than general machinery are put forward higher request. For example, in addition to the material requirements under the state of conventional mechanical performance, still should have low temperature condition of cold resistance properties, such as brittle and axial parts of gear transmission power, because of its extremely strict requirements and the role of material and structure design, the general situation in forging gear blank conditions permit, within the scope of the USES of the whole in the form of forgings. Rim When the addendum circle diameter gear in 2 times, because the trunnion gear and the connection between the axial shaft, often in the form of gear is made.
