The High-end Bearing Relying On Imports Has Be.e Bottleneck Of China Major Equipment Localization-ppbox

Marketing In recent years, China’s hex bolt equipment manufacturing industry has developed rapidly, but most of the high-end pvc fitting bearings that support major equipment are still relying on imports, bearings and other core .ponents have be.e bottleneck of China major equipment development. Large wind turbine bearings, deep drilling rig turntable bearings, offshore plastic valve drilling platform blow molding machine bearings and other high-end bearings of energy equipment are also the weakness of domestic enterprises. China wind power bearings were dependent on foreign imports in a long stage, the price was expensive, the manufacturing cost of per kilowatt wind power equipment had been increase and the decline of the wind power cost also had been reduced. Currently, the scale and series manufacture of domestic wind power bearings has been formed gradually. In wind power bearings, the technical threshold of yaw bearings and pitch bearings is relatively low, while the technical content of spindle bearings and accelerator bearings is higher; the generator bearings are the general products with mature technology. At present, the capacity of domestic wind power bearing enterprises is focused on yaw bearings and pitch bearing , and give priority to the supporting bearings of wind power equipment within 3 megawatts, the spindle bearings and accelerator bearings mainly rely on imports, only individual domestic enterprises get involved in it initially. It is understood that China is far from fully digested on the design, manufacturing and testing techniques of wind power bearings , for example, what kind of bearings is the best for spindle bearing, what kind structure of slewing bearing is well for pitch bearing, how to prevent cracks on the raceway and gear hardening of slewing bearing conveyor , how to ensure the surface hardness and hardened depth and other difficulties are still at an exploratory research. Difficulties did not block China bearing enterprises to develop in exploration. A group of domestic leading enterprises are targeting the world level, they take high-end supporting bearings in 16 key areas as the market guidance, and implement the wire mesh technical transformation with strong investment, high level and fast output, now it has formed a full range of production capacity with 1.5 MW, 2.1 MW and 3 MW wind power bearings. In the Senior Seminar of Bearing Technology and Industrial Development in High-end Equipment Manufacturing recently held, a number of industry experts believe that one of the cable bottlenecks on China’s high-end equipment manufacturing is the lack of high-end bearings, at the same time, the bearing is also the industry that most likely to first achieve breakthrough during the Twelfth Five-Year Period. Mr. Lu Bingheng, the academicians of Chinese Academy of Engineering, he believed that the R & D of high-end bearing related to materials, oil and lubrication, wire mesh manufacturing, design, bearing manufacturing equipment, test and a series of technical problems, but also involved contact mechanics, lubrication theory, tribology, fatigue and failure, heat treatment, materials organization and other basic research and cross-discipline. We must work out key layout in industrial development policy, seal technology development planning and some other aspects, and solve the backward sealing products development of high-end bearing in equipment manufacturing. Only when we organize force from several aspects, attack problems together and do a good job on .bining production and research can .plete the task of moving to high-end bearings.
