Axis pursuing high-end support for high-speed rotation of Chinese equipment

Bearing is a key component in the equipment manufacturing industry. It embodies the country's manufacturing capabilities and manufacturing standards. Bearings have a direct effect on the accuracy, speed, reliability, stability, safety, environmental protection, and longevity of the mainframe, and are used to achieve industrial modernization and defense. The key components of modernization, their performance and quality directly determine the level of development of major technical equipment. The modern equipment manufacturing industry in the United States, Japan, Germany, and Sweden are all supported by a strong bearing industry.

In China, there is such a company that has been hailed by Premier Wen Jiabao as "the hometown of China's bearings." This is China's largest bearing manufacturing company - Wafangdian Bearing Group Co., Ltd. (hereinafter referred to as "Zhaxi Group"). The bearing products developed by the tile shaft support the equipment of the Republic and rotate at a high speed and reliably. "Using precision engineering technology to promote the development of high-end manufacturing in China" is the pursuit and dream of the Wazhou Group for many years.

What won the praise of the Prime Minister In recent years, the Axis Group has seized the historical opportunity of the State to implement the strategy of rejuvenating the old industrial base and the equipment manufacturing industry, vigorously carried out structural adjustments, and fully developed supporting products for 16 major technical fields to transform old companies. At the same time, we have built a "Wazisha Group Precision Technology and Manufacturing Industrial Park" and a "Wage Axle Group Precision Motor Vehicle Bearing Industrial Park" with high starting points and strong investment, and achieved the goal of recreating a tile axis in three years. At present, the automotive axle bearing project of the first phase of the high-speed manufacturing industrial park of the Wazhou Group, which is equipped with bearings for high-end equipment, has been completed and put into operation.

Break through the bottleneck of major technical equipment Although China's national economic construction and equipment manufacturing industry have developed rapidly over the years, most of the high-end bearings for major equipment have relied on imports. The key technology and equipment have been limited by foreign countries. Bearings and other core components have become major national The bottleneck of equipment development has caused the party and the government to attach great importance to it.

In the new energy industry, Wazhou Group has developed large-scale clean and efficient power generation equipment bearings. The ZW axis was the first to develop a complete set of alternative imported products and achieved industrialization in a short time. Currently, it has built a wind power bearing production base with the most varieties of bearings, the largest production scale, the most complete supporting units, and the largest power generation capacity. With 6,500 high-power wind turbines, the company has reached the world's leading level in the three major technical fields of design and R&D, process manufacturing, and testing, and has the ability to support only 5 MW wind turbines in the world. At the same time, the price of imported bearings has been reduced from 2.1 million yuan per unit to 600,000 yuan. With only this one, the social benefit created by the tile shaft has reached 11 billion yuan.

In the petrochemical industry, Wazhou Group developed 200,000 tons of large twin-screw granulator units supporting front and rear thrust multiple bearings, shortening the manufacturing cycle of the host equipment for more than one year, and reducing the cost of the host; developed a 12,000-meter deep drilling rig Turntable bearings, offshore drilling platform series bearings. The successful development of these bearings broke the technical blockade of the foreign bearing industry.

In the iron and steel industry, Wazhou Group has successfully implemented localization projects for large sheet hot and cold continuous rolling complete sets of equipment and coating processing equipment, and developed and developed 2050 rolling mills, which are hot and cold continuous rolling bearings for domestic large-scale steel enterprises; In the past, the precision sheet Sanjimir mill bearings and H-shaped steel vertical roller bearings have been monopolized by three foreign companies. These series of developments and manufactures that meet or exceed foreign-level products have reduced the procurement costs by 70% for the steel industry.

In the mining and coal industries, the Wazhou Group has developed a full range of high-reliability bearings for large-scale elevators, large gearboxes and other equipment, providing safety protection for large-scale coal underground mining and large-scale open-pit mining.

In the field of shipbuilding, port machinery and ocean engineering, Wazhou Group has developed and manufactured supporting bearings for 7,000 tons of floating cranes and 20,000 tons of shore cranes and a full range of walking and lifting machinery. It has developed and manufactured various types of marine cranes for large-scale transportation vessels. Crane turret support bearings. All of these bearings have achieved batch supply, are stable and reliable, and have been highly evaluated by users.

In the rail transit industry, relying on heavy cargo freight lines, high-speed passenger dedicated lines and urban rail transit projects, Wazhou Group has fully developed and supplied 23 tons of axle freight trains with train speeds of 200 kilometers per hour; 30 tons of axle weight and 120 kilometers per hour Heavy-duty truck bearings have been successfully developed, and high-speed bearings for EMUs with a speed of 350 kilometers per hour have passed bench tests. In the process of China’s six major speed-ups and the realization of heavy loads, each time it took the lead in using the products developed by the Zhaxi Group, which has made tremendous contributions to the leap-forward development of China’s railway industry. There are currently 1.8 million sets of railway bearings daily. All are in safe operation, accounting for 52% of all running bearings.

In the machine tool industry and precision equipment industry, the Wazhou Group has made significant progress in the large-scale, precision, and high-speed CNC equipment localization bearing project. It has developed and developed 10,000 rpm high-speed, high-precision, high-power spindle bearings; it has been developed for the development of major engineering automation control systems. Developed joint bearings and slewing bearings for industrial robots. These high-speed, high-precision, high-reliability bearings have been successfully applied to major equipment in the country, breaking the foreign technology and price monopoly.

In the large construction machinery industry, Wazhou Group has successfully developed and supplied 200 to 500 tons of mine electric wheel dump truck bearings in batches; the developed shield main shaft bearings have been provided for the national 863 roadheader testing machine and entered the test verification stage.

In the automotive and agricultural machinery industry, Wazhou Group has developed and developed 8-180 tons of heavy-duty wheel hub bearings, transmission bearings and differential bearings for the Chinese automotive industry series. Currently, the main parts of trucks running throughout the country are more than 55%. Supports the tile bearing.

After many years of technological precipitation, Wazhou Group has initially mastered the core key technologies of bearing R&D, and built five major product test platforms, such as wind power generation, rail transportation, large-scale equipment, automobiles, and machine tools, and has become a supplier of single-bearing manufacturing plants. Innovative solutions for technological solutions.

Wazhou Group undertook the high-end bearing technology research project of the National 973 Program. Seven Chinese academicians from the Chinese Academy of Engineering and 30 experts and scholars from related fields have joined the R & D team of the Wazhou Group to complete the development of the national "Twelfth Five Year Plan". Key equipment to provide support and efforts to tackle.

The two 863 plan projects of the “863-MW Wind Turbine Bearing Research” and “MW-watt Wind Power Bearing Test Bench Construction” undertaken by Wazhou Group achieved significant progress. The series developed 1.5MW, 3.0MW, and 5.0MW fans. Bearings have effectively supported the manufacturing capacity and level of China's large MW turbines to enter the world's advanced ranks.

In September 2009, Premier Wen Jiabao demanded the Axis Group when he inspected on the Wa-Axis. "We must look further ahead, set a higher target, and have the ambition to march into the top three of the world's bearing industry."

Mr. Cong Hong, Vice Chairman and Secretary of the Party Committee of Wazhou Group, told the China Industry News reporter that in the face of the pattern, opportunities and challenges in the development of the world's equipment manufacturing industry, Wazhou Group has determined the guiding principles for the “Twelfth Five-Year” development: to fully implement scientific development.
