Sword High Speed ​​Rail China Bearing Industry Joins Hands to Overcome Technical Barriers

In the face of the excellent situation in the development of high-speed rail trains in China, the bearing industry in China is under pressure and distress in the face of the indisputable fact that China's bearings are not yet equipped with high-speed trains.

What is gratifying is that during the “Eleventh Five-Year Plan” period, supported by the Science and Technology Support Program of the Ministry of Science and Technology, Luoyang Axis Research Technology Co., Ltd. (reformed enterprise of Luoyang Bearing Research Institute) took the lead, uniting with Luoyang LYC, Haz axis, and Chengdu Branch. China and other universities and universities such as Henan University of Science and Technology and Chongqing University have carried out R&D of high speed iron bearings with a speed of 350 kilometers per hour. They have developed the first set of samples and conducted some performance tests. Although they have not been applied, they have taken a step toward localization.

The leaders of the China Bearing Industry Association pointed out that China is a big country in the world, but it is not yet a world power. Relevant information shows that in 2009, bearing production in the bearing industry in China reached 10 billion sets, and the total output value has reached 90 billion yuan, ranking third in the world. There are 1750 enterprises above designated size, of which 5 have annual sales of over 3 billion yuan. However, high-speed bearings such as high-speed railways, wind power, and machine tool spindles have always been the soft underbelly of the Chinese bearing industry, relying mainly on imports. The deficit of more than 800 million U.S. dollars in China’s bearing imports and exports in 2009 illustrates this point.

China Axis Association experts pointed out that objectively speaking, during the “Eleventh Five-Year Plan” period, China’s bearing capacity for major equipment has been greatly enhanced, with spacecraft represented by “Shenzhou” series spacecraft, “Chang'e-1” and large thrust rockets, etc. Bearings for aerospace and other defense equipment are all based in China and have full independent intellectual property rights. In the first three years of the “Eleventh Five-Year Plan”, 488 kinds of supporting bearings for 90 major equipments in 13 key areas of the country’s 16 key areas were developed. Among them, the wind turbine generator yaw pitch bearing, deep well ultra-deep well oil drilling machine bearing, heavy-load railway wagon bearing, YRT series CNC machine tool spindle bearings have been realized in China.

Integrating Resources to Improve Industry Competition According to the “Medium and Long-Term Railway Network Plan (Adjusted in 2008)” of the country, by 2020, the mileage of China’s high-speed railways will reach 18,000 km. This figure is currently at high speed in Germany, Japan, and France. Three times the total railway mileage (6,000 kilometers). By 2012, the total mileage of China's high-speed railway will reach 13,000 kilometers, which will create 800 new demand for EMUs, providing a broad market space for high-speed train bearings in China. At present, the mileage of high-speed railways in China has reached 7055 kilometers. Experts in the industry estimate that the market for high-speed rail bearings will exceed RMB 2 billion. More importantly, the development of high-speed rail bearings will significantly increase the innovation capability and technological level of China's bearing industry.

Resolving the issue of high-speed bearing R&D as soon as possible is undoubtedly a major event for the China Axis Association.

In the face of the grim reality that all high-speed rail bearings were imported, on July 20, 2010, China's Axis Association organized an industry “one plant, three factories and one school” to hold the “High-speed Railway Passenger Car Bearing R&D Conference” in Beijing. China Axis Association attaches great importance to the industry's backbone enterprises to respond positively. The Secretary-General of the Chinese Axis Association Wang Quanqing presided over the meeting. The leaders of the China Axis Association, including Chairman Liu Enshi, Honorary Chairman Zhang Qiaofan, Senior Consultant Yang Naiyan, and Deputy Secretary-General of Beijing, attended the meeting. Wu Zongyan, Chairman of Luoyang Axis Technology, He Jinguang, Deputy Chief Engineer of Harbin Bearing Group Co., Ltd., Qu Rongjun, Deputy Chief Engineer of Wafangdian Bearing Group Co., Ltd., and Pang Bitao, Chief Engineer of Luoyang L丫C Bearing Co., Ltd., Henan University of Science and Technology College secretary Ma Wei and other relevant unit leaders and experts attended the meeting.

Why is it called a job fair? The relevant leaders of the China Axis Association pointed out that the Axis Association is a first-level civil society organization and does not represent the government. Please ask everyone to discuss whether there is any possibility of cooperation.

It is understood that in addition to the above five units, Tianma Bearing, Renben Bearing, Chengdu Kehua, and Wanxiang Qianchao are also interested in participating in the research and development of high-speed rail bearings.

Wu Zongyan, chairman of Axis Research, believes that R&D of high-speed rail bearings is a demonstration of the strength of China's bearing industry, and joint research will reduce the development cycle and funding.

Zhu Rongjun, deputy chief engineer of Zhaxi axis, pointed out that high-speed rail bearings have high technological content and long research and development cycles. Everyone joins together to complement each other and reduce duplicate investment. It will accelerate the development of high-speed rail bearings and significantly reduce R&D investment.

Luo Yang, chief engineer of Luoyang LYC, stated that Luo Xiong firmly supports the proposal of joint research by the Chinese Axis Association and is willing to actively participate in this work under the promotion of the China Axis Association.

Qingdao Sifang Vehicle Research Institute is the authoritative organization for the research of railway vehicles in China. Professor Kejun of the professor level recommends that the research and development and industrialization of domestic high-speed railway passenger car bearings should proceed step by step, starting from 200 to 250 kilometers per hour.

The delegates agreed that the Chinese Axis Association should take the lead in organizing the R&D of high-speed railway passenger car bearings. Under the leadership of the Axis Association, we will integrate the advantages of industry resources and focus on the strengths of all parties in the industry to solve the current problems of companies fighting alone and fighting each other and avoid duplication of investment.

Chairman Liu Enshi pointed out that at present, the country attaches great importance to the development of high-speed rail, and the Ministry of Railways has drawn up plans for speeding up development of the “four vertical and four horizontal” system. As an important key component for the operation of high-speed railways, rolling bearings accelerate scientific and technological research and development, and realize localization as soon as possible, and it is imperative to meet the requirements. However, the development of high-speed rail bearings is not something that a single company can do alone. It requires everyone to participate and develop together. This road is difficult to start and the direction is correct. We must unswervingly continue to develop wind road bearings and large aircraft bearings in the future. The task of the consortium is to integrate industry superior resources, establish a high-speed bearing technology platform, share technological achievements, promote the research and development of high-speed railway bearings, and comprehensively upgrade the overall technical level and competitiveness of China's high-speed railway bearings.

He finally put forward the specific requirements of “2 reliances, 4 establishments, and 5 ones” on behalf of the China Axis Association. They relied on the Sifang Institute and depended on the Institute of Iron & Steel; established feasibility planning for the R&D production of high-speed rail bearings and established a green channel with the Ministry of Railways. , establish related national ministries and commissions to contact the green channel and establish a joint unit related responsibility system; a drawing to the Ministry of Railways, a department to take the lead in scientific research (Luo axis), a department to maintain contact with the relevant national ministries, a department to coordinate the Ministry of Railways, A department coordinated the progress of scientific research and production.

Joint Strike Against Technical Barriers on October 14, led by Luoyang Axis Research, Luoyang LYC, Ha-axis, tile axis and other three companies, Tsinghua University, Chongqing University, Hefei University of Technology, Henan University of Science and Technology and other six universities, Qingdao The research and development team of Sifangsuo, Changchun Passenger Car and Tangshan Bus participated in the “12th Five-Year” Science and Technology Support Project “Research and Application of Key Technologies for High-Speed ​​Railway and Urban Rail Vehicle Bearings” by the Ministry of Science and Technology.

China's bearing industry adopts the “industry, study and research” four-in-one R&D model. The sword refers to the high-speed iron bearing, and it strikes jointly to strive for victory.

However, core technologies have created barriers to entry in the high-speed railway bearing market. Several multinational companies have mastered the core technologies and will not be easily transferred.

How to break through technical barriers is a challenge to the independent innovation capability of China's bearing industry.

Chairman Wu Zongyan pointed out that the R&D of high-speed railway passenger car bearings involves a series of technical problems such as design, manufacturing, materials, lubrication, manufacturing equipment, testing and testing, and also involves basic research and cross-cutting of contact mechanics, lubrication theory, tribology, and heat treatment. Subject. Only by organizing multi-faceted forces to tackle problems together and doing a good combination of “production, research, and application” can we accomplish the task of research and development.

The science and technology support project will mainly study bearing structure optimization design and CAE simulation analysis, bearing long life, high reliability technology, materials and heat treatment technology, detection and testing technology, intelligent bearing sensor integration and matching technology, lubrication and sealing technology, processing and Matching technologies and other key common technologies.

The project emphasizes the close integration of "production, research, and use." In the project implementation process, a group of high-level R&D talents will be trained; a high-speed railway bearing research and development base will be formed with key laboratories, engineering centers, and backbone enterprise technology centers; and a batch of scientific research institutes, universities, and backbones will be established. The enterprise's high-speed railway bearing performance test and testing platform.

The research and development and industrialization of high-speed railway passenger train bearings are very arduous. We must give full play to the initiative and enthusiasm of all enterprises. Under the premise of protecting the proprietary production processes and intellectual property rights of all enterprises, we must integrate the strengths of the industry to carry out joint R&D research and development. The drawings and technical conditions of high-speed railway passenger car bearing products approved by the Ministry of Railways will gradually realize product support.

An expert from Luoyang Axis Research Technology stated that during the “12th Five-Year Plan” period, the Chinese bearing industry is confident that the high-speed railway passenger cars supporting domestically-made bearings will be on the ground in China.
