High-end bearing the importance of China in the future

High-end bearing is related to the national economy and people's livelihood important basic components and the security of national defence, the powerful of the high-end bearing industry of a country's comprehensive strength, has a close relationship with China has become a manufacturing power, represented by high-end bearing the key basis of zero parts has become the bottleneck of restricting to further improve China's industrial level, therefore vigorously develop high-end bearing industry of our country development is important. Our country must firmly grasp the development of high-end bearing, clear the development trend of high-end bearing, on the basis of perfect the related system, give full play to the administration of the production, use and so on various aspects strength, strengthen independent research and development and technical research, accelerate the development of China's high-end bearing. The development trend of high-end bearing ( A) High-end development trend of the rolling bearing for wide scope of application of rolling bearing, industry wide, a slightly different industries the demand for technology and developing trend of 1. Air bearing in order to meet the demand of future aircraft, a air bearing pay more attention to integration and intelligent design, to meet the higher temperature, higher speed, higher reliability of performance indicators. At the same time, the advanced ceramic materials, composite materials, thermal cooling structure design and the lightweight design is also gradually to the application. The main trend including: ( 1) To the high temperature and high speed development of overloading, make main shaft bearing materials continuously breakthrough bearing capacity and high temperature performance; ( 2) To the integration of a shaft, gear bearing structure development, in order to reduce weight and improve the reliability of the engine; ( 3) With M50NiL, ceramic roller, Cronidur30, CSS - 42L. As the representative of advanced bearing materials and process technology accumulate through long-term exploration has been gradually service; ( 4) Adoption and integration of advanced surface engineering technology, in order to improve the bearing ability to work the ability to resist fatigue and fracture of oil ( 5) Air bearing design technology constantly improve, and formed a complete design, prediction, optimization and virtual prototype design ( 6) Important air bearing is implemented by the breakdown maintenance or regular maintenance to the apparent transformation and maintenance technology system developing in the direction of intelligent, smart bearing will play an increasingly important role
