“in 12th Five-Year, ” during the period, in order to accelerate the development of advanced manufacturing industry, improve the domestic level of major equipment, further encourage the development of large, precise, special forgings technology and equipment manufacturing, the &ldquo issued by the Ministry of industry and industry in 10 of 2010, the implementation scheme for the revitalization of machinery base parts and spare parts, and listed key drums. The development of the development of the gear transmission equipment 10 major categories, focusing on the development of high precision gear equipment, for gear industry supporting the forging manufacturing enterprises face a rare opportunity for development.
China gear transmission industry in “ 11th Five-Year ” during the period of rapid development. According to the data published by the National Bureau of statistics and the China gear professional association, the total industrial output value of the gear industry in China has increased year by year in 2005-2010 years, and the increase is above 20% year on year. In 2010, the total industrial output value of the industry was 94 billion 635 million yuan. The gear industry has become the largest industry in China's mechanical infrastructure.
Forgings, as an indispensable part of the gear industry, account for more than 30% of the total price. The market demand is increasing with the rapid development of downstream industries. In the future, with the improvement of the overall technical level of the large equipment manufacturing industry in China, the diversification of the transmission equipment and the continuous improvement of the technical content, the industry of the transmission equipment manufacturing will get more space for development, which will bring great opportunities for the development of the gear forging enterprises.
1. Wind power equipment
The gear in the main engine of the wind power is the key part of the wind power generation equipment. Its main function is to use the speed conversion function of the gear and speed up the rotary speed of the fan blade to the rotational speed required by the generator.
In recent years, due to global warming and the importance of energy conservation and emission reduction and new energy utilization, wind power market has maintained rapid growth in the past ten years. According to the World Wind Energy Association ( WWEA ), the global wind power installed capacity reached 159 million 210 thousand kilowatts at the end of 2009. In 2009, the new installed capacity was 37 million 500 thousand kilowatts, up 31%, the new installed capacity of 16 million kilowatts in the first half of 2010, and the accumulati
