it is also to ensure that the same level of durability as the original

 Increasing the rotation radius of curvature of the surface of the groove, the rolling bearing can reduce the frictional resistance. However, if the radius of curvature increases, the contact surface pressure between the ball and the plane of rotation between the bearing load will increase. In particular, the rotation, the durability of the bearings will decrease, thus increasing the radius of curvature of the simple approach has been difficult to achieve. DNT Andes contact position with the ball and rotating the load acting on the surface due to the size of the wheel hub bearing different characteristic change occurs, developed the new bearings. Compared with the original, in the contact position of the straight running is increased when the radius of curvature of the trench, and the radius of curvature of the contact position split tapered roller bearing‍ during rotation remains the same as the original. By this method, when the straight traveling wheel rolling bearing to reduce frictional resistance, it is also to ensure that the same level of durability as the original. It also reduces the product than the original preload range, further reducing the frictional resistance.

Previously, the company accounted for by reducing wheel bearing friction half of the seal sliding resistance, developed about 15% lower friction wheel bearing seal, and by virtue of the product development market. The development of the use of technology that allows the wheel hub bearing rolling resistance reduced by about 25%. Coupled with a low friction bearing seal design allows maximum reduction of friction when traveling Cylindrical roller bearing‍ straight 40%. Development of large wind power bearing ranks among the world's most advancedAn investment of 250 million yuan in the Shanghai Electric Wind Power bearing large production line technological transformation projects, recently completed and put into operation in Shanghai. The first 3.6-megawatt offshore wind power bearing downline, indicates that China already has a world-class innovation and efficient wind power bearing design and development and manufacturing capabilities, as China's "Twelfth Five-Year" period to develop wind power industry reinforce the foundation.

the Chinese bearings are Wafangdian Bearing industrial output reached 23 billion yuan (RMB), an increase of 29.2%; industrial added value of 35.3 billion yuan, an increase of 28.8%, the bearing industry has become the first Wafangdian an industry. Wafangdian party secretary Xing-Wei Liu said the city is in accordance to build two industrial clusters and the idea of ​​the six industrial base, the introduction of nurturing top talent, improve the high-end research and development capabilities in an effort to "bearing capital" Wafangdian, playing with a tip the development of Cylindrical roller bearing a world-renowned city bearing capacity.
Area of ​​less than 3,800 square kilometers of Wafangdian, but it is the birthplace of China's bearing industry, developed Tapered roller bearings more than 500 years of "ZWZ" led by bearing production and ancillary businesses. Among them, the size of the business 258; sales revenue over $ 50 million enterprise 27 million over the business 9. 2009 achieved sales revenue of over 150 bearing billion. Bearing industry Thin section bearing practitioners 5 million, accounting for 16.1% of total employees in the same industry, accounting for about 20% of the national total output value of the industry.
Liaoning Coastal Economic Zone grasp opportunities
Xing-Wei Liu stressed Wafangdian in Liaoning coastal economic zone are to seize the development of open and Dalian global urbanization strategic opportunities, and vigorously promote coastal paired tapered bearing development, vigorously develop strategic emerging industries, to enhance urban functions, improve people's livelihood well-being, for the "second five "to achieve a new leap in scientific development and lay a solid foundation, built in the Bohai Sea region will Wafangdian competitive emerging modern industrial city.

paired tapered bearing Speech forum four experts, scholars

During the Fair, Luoyang Bearing Industry Association hosted the 2013 China (Luoyang) Bearing Industry Forum. Forum Luoyang Bearing Industry Association Ye Jun chaired the forum by China Bearing Industry Association executive vice president Wang Tapered roller bearings  announced the opening of China Bearing Industry Association specifically Fellows, senior engineer Ho plus group, Mechanical Engineering Department of tapered bearing  niversity Sok double rich Ph.D., Luoyang bearing Science & Technology chairman Dr. Wu paired tapered bearing  and Beijing Institute of Technology School of mechanical and Vehicular Engineering, Dr. Wang in the other four experts and scholars at the forum were on "China's bearing industry to upgrade, from large to strong roadmap" "the Present Situation and development Strategy of high-end bearing our", "the latest development of China's high-performance bearing technology", "high Performance Rolling basic research" and other major issues delivered a wonderful speech.
Part of professors and graduate students from Zhejiang, and Guangdong Province, Luoyang City, bearings and bearing related businesses and Tsinghua University, Beijing Institute of Technology, Hefei University of Technology, Henan HKUST, Xi'an precision bearings  University, Southeast University and other universities and Luoyang City, the industrial parks and government industries authorities responsible persons a total of 300 people attended the forum. Speech forum four experts, scholars, on the Chinese bearing industry in the development of major directional issues raised  test the value of advice and ideas for bearings and bearing related enterprises to achieve the transformation and upgrading, speed up industrial upgrading, product level enhance the core competitiveness provided important guidance for Luoyang bearing industrial transformation and upgrading, structural adjustment and healthy development of the industry will have a major impact. Forum speakers praise the participants.
