Gear Hobbing machine is one of the most widely used machine tools in gear processing, can cut straight teeth, helical teeth, cylindrical gear, but also can process worm gear, sprocket and so on. Gear hobbing machine is divided into vertical and horizontal two types according to the layout. Large and medium-sized hobbing machine for vertical, small gear hobbing machine and dedicated to processing long shaft gear hobbing machine are horizontal. Vertical gear hobbing machine is divided into two kinds of table movement and column movement.

Funds entering new energy The UN report said that the global investment in renewable energy has reached 80 billion U.S. dollars in 2005, and in 2006 it was as high as 100 billion U.S. dollars. The capital invested by investors in this industry in 2006 increased by 43% compared with the same period of 2005, and new energy has thus become the most popular investment opportunity.
The gradual crisis of oil is not a day. At the beginning of the century, the era of cheap oil began to come to an end, and the price of oil has since embarked on the path of continued unilateral rise.
And as early as 30 years ago, a group of Western scholars predicted this fact. They gathered in Rome, Italy to discuss whether the resources on Earth are still enough to use. Will humans fall into an energy crisis? Later, they issued a declaration entitled “The Limit of Growthâ€, pointing out that the resources on Earth are limited and cannot be obtained by human beings indefinitely.
“The most renewable energy sources that attract the attention of investors are wind power, solar energy and biofuels.†Many authoritative organizations such as the International Financial Dispute Resolution Center and the China Institute of Finance stated that “the stock market in 2006 was technologically developed and commercialized. Investors in chemical and manufacturing companies increased by 140% year-on-year in 2005, while venture capital and private capital investments increased by 163%, and financing for power generation assets and capabilities also increased by 22.9%.â€
The report shows that the new source of financing for power generation, the largest source of renewable energy investment, accounted for 40% of the US$70.9 billion invested in 2006, reflecting the coming of the era of new energy industry. This trend will continue in 2007. Most of the asset financing transactions are in the relatively mature wind energy industry, and the second is the biofuel industry.
Renewable energy has nothing to do with unpredictable oil prices. They are becoming the new darling of more and more power generation groups, communities and governments, and do not care about the cost of fossil fuels.
Many authoritative organizations such as the International Financial Dispute Resolution Center and the China Financial Research Institute expressed that renewable energy now competes with coal and gas power generation in terms of new power generation capacity and the world's energy. Renewable energy will surely make hundreds of millions of investors profitable.
The development of green energy in China Green energy is also called clean energy. It can be divided into narrow sense and broad sense.
The narrow sense of green energy refers to renewable energy sources such as hydropower, bioenergy, solar energy, wind energy, geothermal energy, and ocean energy. After these energy sources are consumed, they can be replenished and there is little pollution. The broad green energy includes the use of low-pollution or non-polluting energy sources, such as natural gas and clean coal, in the process of energy production and consumption. The conversion of coal into chemical gas or "coal" oil through High-tech closely controlled combustion is converted into electricity) and nuclear energy.
The Chinese government has strong strength and willingness to implement projects such as emission reduction, clean energy and green lighting. In the past two to three years, China has actively transformed its ideas and decisions into real actions.
China can also formulate laws and regulations and implement them at the grassroots level, including rural villages and towns. At the same time, an evaluation and evaluation system is needed to measure the grass-roots emission reduction performance from the perspective of GDP. He disclosed that the United Nations and the Chinese government have reached an agreement to promote China's green energy development.
As early as the 1950s, China promoted biogas in rural areas and achieved remarkable results. At the beginning of this century, the country decided to develop fuel ethanol. It has established large-scale fuel ethanol production enterprises in the Northeast, Central China, and East China, and has established relevant standards for gasoline and alcohol. Some provinces and cities have already used gasoline for alcohol. The country has also invested considerable energy in organizing scientific research and scientific and technological breakthroughs in bio-energy and has achieved gratifying results. It has reached a very high level in terms of productivity microbiological research, biotransformation research, process and equipment research.
China is rich in biomass resources. It produces about 500 million tons of grain every year. At the same time, it produces more than 700 million tons of straw. Apart from feed, fertilizer and other industrial raw materials, at least half of it can be used for bioenergy. With livestock manure and forest processing residues, China's existing biomass resources available for bio-energy development will reach at least 450 million tons of standard coal, equivalent to about 40% of China's total primary energy consumption in 2000. In addition, there are still about 2 billion mu of land suitable for agriculture and suitable for afforestation, which can be used to develop energy agriculture and energy forestry.
Experts from the International Financial Dispute Resolution Center and the China Institute of Finance estimate that in the next 30 years, China will be able to develop at least 2 billion tons of bio-energy, plus nuclear, hydro, wind, solar, geothermal energy, and traditional fossil energy and development. With regard to energy-saving technologies, China’s energy supply is sufficient to support the rapid and sustained development of China’s social economy.
High oil prices are tight, and new energy sources that are theoretical alternatives will certainly become "darlings". Smell the "bloody" international financial capital has begun to attract attention "green energy"
