Chinese wind power industry and wind power bearing market potential

Chinese exploitable wind energy to total about 1 billion kW (of which the land wind energy reserves of about 297,000,000 kilowatts, offshore crane bearing wind energy reserves of about 750,000,000 kilowatts),

agricultural bearings，by the end of 2006, China's wind turbine installed capacity of 2.6 million kilowatts, can be developed wind power accounted for only less than 3 of the total%, the wind power bearing industry development with big potential.

Wind power bearing driven by the wind power industry

The rapid growth of the wind power bearing industry, must be based on the rapid growth of wind power equipment as the support,which will inevitably lead to strong demand for bearings in wind turbine.

  In recent years, the world's two wind power bearing and deck crane bearing suppliers although full load production, also in short supply, or loving some wind power equipment  bearing manufacturer has to China buy bearings.

Wind power bearing and the future wind power development

The future of wind power has the very big development space. European plan to achieve by 2020 renewable energy accounted for 20% of the total generating capacity,wind power bearing accounted for 12%.

  It is understood, now the global wind power accounted for the proportion of total generating capacity is only 1.10%. To achieve the 12% target,agricultural bearings also need to grow nearly 10 times.

  European wind energy Association predicted that, prior to 2020, the annual increase of wind power installed capacity will be maintained at more than 15 million kilowatts.

Wind power bearing and global wind power development

The relative scarcity of traditional energy, environmental pressure and geopolitical strong sense of insecurity,deck crane bearing so countries spare no effort in the development of renewable energy including wind power. The wind power industry has been covering the continents of the world, and the trend of rapid growth.

  By the end of 2006, global wind power installed capacity has reached 74,223,000 kilowatts, by the end of 2006, wind power bearing installed capacity of more than 1000,000 kilowatts countries Germany, Spain, India, Denmark, USA, China ranked 6.

Wind turbine generator shaft conclusion and wind power bearing

Japan and Europe and the United States compared to wind power generation popularity of atmospheric conditions, Japan is seeking to adapt to the typhoon, lightning and other weather conditions in winter in Japan high reliability of wind power bearing generator.

NTN is committed to improving the reliability of the fan bearings,agricultural bearings let the wind machine manufacturers and users to rest assured that the use of bearings, provide very good the most suitable bearing specification selection and high quality products for wind turbine manufacturer and user thereby,deck crane bearing make greater contributions to the development of global wind power generation.

Taper roller bearing longevity

In order to achieve taper roller bearing longevity,we can use carbonitriding of ETA bearing processing.

  ETA bearings, as a special heat treatment, residual austenite and carbide surface part of the dispersed properly, good thermal stability, high tolerance to peeling strength of foreign body in lubricating oil, is a kind of long life wind power bearing .

  Through the correlation method, we have reached the requirement of bearing technology of small, high reliability.

wind power bearing and bearing for yaw gear box

Due to yaw gear box requirements for small and large torque transmission, so the deck crane bearing is also pursuing a small design and high load capacity. Therefore, the raceway ring use thin-wall angular contact ball bearings and taper roller bearing .

If the angular contact ball bearing load large axial load, it is necessary to improve the inner ring andouter ring raceway groove rib height, as a special design to increase the allowable axial load.Compared with the yaw gear box for special products and standard products, ensure Gao Rongxuaxial load of about 9 times（wind power bearing）.

The car wheel bearing of the past

The car wheel bearing of the past is the most used in pairs of single row tapered roller or ball bearing.

   With the development of technology, the use of car wheel hub unit cars have been widely. The scope of use of hub bearing unit and use the growing, has now developed to the third generation.

   The first generation is composed of double row angular contact bearing components. The second generation in the outer raceway has a flange bearing for fixed, will be simple bearing sleeve to the shaft is fixed by the nut, making the car repair easier.

Insulation bearing for generator

Bearing  used for generator,to prevent the phenomenon of electric spark for bearing internal conductive induced (electrical erosion), and improve its reliability is essential.

  We have developed through the use of special ceramics and improvement of metal spraying method, ensure that the monolayer type insulating ability and reliability of the new deck crane bearing product.

  Insulation resistance value more than 100M Omega, dielectric breakdown voltage of insulating performance is more than 2KV, the insulation performance to meet the requirements of wind power bearing generator.
