Wind power equipment mainly include the following several parts: transmission (acc), generators, leaf, Kentucky and substation, etc. At present, wind power generator power to develop gradually, high reliability, long life cycle, so the precision components, function requirement is high.
Along with the development of wind power technology, the principle and structure of the wind generator also is in produce change, wind power generator in the future to reduce the volume of simple structure, the development direction. At present, our country is developing wind power generator no gear box. Like Harbin power equipment group of generating equipment engineering research center is developing variable speed gearbox permanent wind turbine generators, are being developed "wind generators" and "direct driving speed of wind turbine generators" etc, can replace belt transmission gearbox of asynchronous generator, with low cost and reliable operation, simple maintenance etc, and has independent intellectual property rights.
At present, there is the largest production gearbox wind turbine generators, due to the complicated structure and its various parts of the machine equipment manufacturing needs different processing.
The main transmission by fan speed and still box, etc. Fan speed cabinet, according to a large cabinet belong to the different diameter, about 2 ~ 3m, most for fission. Stem diameter to boring 160250mm nc milling and boring and large-scale horizontal ground processing center, the high accuracy, processing, mainly using imported equipment.
The gear transmission, need for large manufactured in gear and spur gear and helical gears for mass production, etc. Main processing equipment for large nc vertical gear hobbing machines, CNC noninvolute tooth grinding machine, etc. The gear processing machine, CNC machine general specification big gear with efficiency and requirement, cutting, rigid overloading good characteristics, main rely on imports, domestic equipment and USES. One big norms, big modulus gear and gear adopts CNC milling machine and nc forming grinding gears forming machine, CNC milling gear shaping too large, deep cut confidential, high speed feeding. Nc forming grinding machine precision requirements above 5 levels, a high degree of automation, automatically adjustable, automatic measurement, automatic, high stability. At present, the domestic manufacturing enterprise mainly with the power transmission gears Co., LTD has high precision in nanjing. The task is very busy, long-term 3, still cannot completely meet the market demand, so request processing equipment is stable, reliable, currently USES gear cutting machine is basically imported equipment.
