Backing bearings innovation capability

China's bearing industry currently faces three major outstanding issues: namely, industry production concentration, low R & D and innovation capability, low level of manufacturing technology. First, a low concentration of manufacturing industries. Bearing worldwide sales of approximately $ 30 billion, the world's eight major multinational companies accounted for 75% to 80%. Germany, the two companies account for 90% of the national total, bearings for rolling mills  accounted for 90% 5 of the national total, 56% of the United States one of its national total. In China, such as 10 Wazhou largest bearing company sales accounted for only 24.7% of the entire industry, before 30 production concentration of only 37.4%. Experts believe that the reasons for this: First, the original large state-owned enterprises due to problems on the system and mechanism, the relatively slow development; the second is the advantages of private, private enterprise is still in the growth stage; third is low-level redundant construction, industry factory point too scattered, General Bearing serious excess capacity. Second, Backing bearings low R & D and innovation capability. Due to funding the construction and operation, R & D and innovation, most companies invest in innovation system, personnel development and other aspects are still at a low level, precision bearings with research institutes towards enterprise service-oriented industry, the state has no common industrial technology research investment, thus weakening the industry-oriented research and development functions. Therefore, the entire industry, "the two least two weak" outstanding, basic research that is weak, participation in international standards development is weak, less original technology, less patented products. At present, our design and manufacturing technology is basically imitate, consistent system for decades. Product development capacity, and performance: Although a host of supporting domestic rate of 80%,Tapered roller bearings  but the high-speed railway passenger cars, luxury cars, computers, air conditioners, high levels of mill and other important bearing host support and maintenance, basically rely on imports. Third, the low level of manufacturing technology. Bearing industrial manufacturing processes and process equipment and technology development of China's slow, low CNC lathe, grinding low level of automation, there are only more than 200 automated production lines. Most companies, especially in the old state-owned enterprises as the main production is still traditional equipment.

slim section ball bearing accelerated into the world's top ten bearing

Faced with a historic opportunity of rapid development of machinery industry and the revitalization of northeast old industrial base, slim section ball bearing Group LLC momentum, accelerate the development slim section ball bearing of industrial output value 2.48 billion yuan, 3.02 billion yuan sales income, profit 170 million yuan, exports $ 42 million. On this basis, Wazhou also proposed an early realization of the goal of entering the top ten in the world bearing. Wazhou rapid development in recent years, mainly due to its marketing service network to achieve results. The company's top ten selling the company's sales department from 29 to 37, the new 29 foreign agents in the country has established 20 distribution centers. With thanks to its national policy, starting point for technological transformation. Major equipment items precision bearings, large precision bearings experimental research platform transformation projects, seven projects have been included in the "bond projects." Thanks to further enhance its R & D capabilities. 596 kinds of new products throughout the year, the transformation of the old 210 kinds of products, Slim-bearing to replace imported products 230 kinds, 34 completed the process of innovation, patented 30. Thanks to its insistence on mechanisms and institutional innovation, and vigorously promote the separation of major. The forging factory, stripped the ball branch restructuring and the market as a whole, after the restructuring of production and sales were up 30 percent over last year. Thanks to its lower costs for promoting the use of "Resource Efficiency Action" effect. Implement only online bidding, slim section ball bearing 82 million yuan the year to save money. Faced with more intense market competition, in order to achieve an early goal to enter the top ten in the world bearing, precision bearings  proposed to promote the "four accelerate project" to complete the "Ten transformation project" to achieve "double six goals." "Four Acceleration Project" are: accelerating the reform of property rights system and operation mode, accelerate the adjustment of product structure, accelerate technological innovation and technological innovation, accelerate the construction of marketing services network. "Ten transformation projects," including: large equipment bearing projects, railway projects slim section ball bearing, automotive bearing items, auto parts projects. "Six double goal" is: By 2005, sales, product exports, with a variety of products with independent intellectual property rights, labor productivity, gross profit and income of workers six indicators to be based on the double six indicators,, on the basis of the double again. At the same time, promoting the brand strategy, strive to enter the ranks of the "China Famous Brand".

Slewing CAD research and development

In the design of slewing expert system technology, finite element analysis and parametric drawing technology to construct a set of design, structural analysis, and automatic drawing in one of the rotary Bearing test machine CAD systems, introduced the system's structure and main modules set rotation supporting widely used in automobile cranes, excavators and other construction machinery and mining machinery radar, automatic tracking artillery and other military products. Slewing ring design theory of research carried out less, essentially using traditional design methods, design standards and bench are behind Germany, Japan and other developed countries.
There are many types of slewing ring, it is designed both types of options, there are forces and structure size calculations, set the value of the non-expert planning, and numerical reasoning process of scientific computing in one. Therefore, in the design of slewing expert system technology, with major engineering application value. Survey showed that in the low-speed heavy slewing generally work under conditions, resulting in the failure of the cause is due to structural weak part of insufficient strength. Therefore, slewing static finite element structural analysis, which can effectively predict slewing bearing capacity and weak links, and process re-engineering measures for the adoption direction. Parametric drawing technology in the CAD system design and development in an increasingly wide range of applications, its advantages in systematic product engineering drawing is particularly prominent. In this paper, the full collection and analysis of slewing ring design data and design experience, based on the research and development of design, structural analysis and automatic drawing in one of the rotary bearing CAD system.
Slewing system architecture and design CAD ​​system brings together the database technology, knowledge base technology, computing and reasoning techniques, finite element analysis techniques and parametric drawing technology. The system consists of expert system design, finite element analysis and parametric drawing three parts. Both between the various parts combination, collaboration, and functional independence, each module can be used alone as a subsystem through the system function of each module framework will combine to satisfy the needs of users
