Non-standard bearings gradually became important basic components? Source: bearing | last updated: - 2020 09 - 25 non-standard bearing gradually became important basic components? Non-standard bearings bearing is the key in the high-end equipment manufacturing, important basic components, the immediate decision to heavy focus on the characteristics of weapon equipment and server product, quality and credibility, referred to as the 'heart' components of the equipment manufacturing industry. After many years, the development trend of bearing industry chain in China already has a large scale, all over the country bearing areas 2010 annual output value is about 130 billion RMB yuan in China, ranks third in the world. Although the scale of development trend in the field of the bearing is already very big, but the vast majority of all centralized in low - and, in the high-end bearing manufacturing industry, in our country compared with capitalist countries still have very big difference. China bearing industry association director Wang Quanqing has also established show that development trend of China's high-end bearing rate couldn't keep up with the development trend of the server rate. For example, in our country has mastered high-speed emu with independent patent technology, but with the facilities of the bearing foundation also rely on imports. At present, China bearing company manufacturing high speed bearing 150 - most only considered 180 km of the train, and European countries high-speed rail train speed 350 - bearing 400 km the requirements of the train, therefore, the present stage of China's speed of 200 km above the bullet train of supporting facilities imported high-speed rail train bearing based on high prices. According to the high-grade bearing out objective facts in our country, 'planning' established, will make full use of national industrial policy correctly guide effect, promote domain access threshold, the boycott of basic construction suitability repeatedly; To include within the bearing industry chain 'sanki' industrial chain of taxation for current policy, the implementation of the important components and raw materials import tax preferential policies; Scientific research to formulate incentive customers choose 'sanki' new product and new technology and new technology of the existing policy. How to develop good reasonable maintenance of non-standard bearing? Application perspective speak to pay more attention to the following aspects: moderation, bearing gap caused by impact, is too small, poor RunHua, tile burning. Bearing and motor shaft process performance and geometry appearance should be strict to ensure. Improved RunHua quality, manipulation of automobile engine oil pressure, temperature and total flow, improve automobile engine oil filtration. Control the temperature of the diesel engine, under the condition of low temperature overtemperature work is all bad. Winter, heating the diesel engine starting before you, and with the hand engine crankshaft rotation of automobile engine oil into the friction surface. Choose meets the requirements of gasoline and diesel, and grease.
