The application of bearing in mechanical field

one Generator bearing automobile generator for automotive engine is an important feature, installed in the engine front, with the air conditioning compressor, water pump, fan and other features. Used in automobile generator bearing at high temperature, high speed, heavy working conditions. two Wind wind power bearing, bearing the yaw bearing and variable plasma bearing technical threshold is relatively low, and the main shaft bearing and speeder bearing technology content high, the generator bearing basically for skilled gm products. , therefore, the current domestic wind power bearing capacity of enterprise is mainly concentrated on the yaw bearing and variable plasma bearing, the following 3 mw wind power equipment form a complete set of bearing can be mass production, domestic replacement rate has reached more than 80%, annual production capacity has reached more than 60000 sets, but for the main shaft bearing and speeder bearing, basic or imported, only some enterprise initial intervention, was still in the stage of development. 3. Steel and non-ferrous metal rolling mill bearing steel in the process of rolling mill bearing arrangement in need under high load, high temperature and in most cases is work, work under the condition of serious environmental pollution, so in addition to using the standard rolling bearing, also need to use some special bearings for use in the condition of four. Lifting transportation machinery bearing lifting transportation machinery is within a certain range of vertical and horizontal carrying heavy more mechanically. Lifting transportation machinery mainly includes: the quayside container crane, rubber-tyred container gantry crane ( A bridge) , bulk pack, ship unloader, bucket wheel stacker reclaimer, door crane, belt conveyor, reclaimer, bridge crane, jib crane, unloading machine, stacking machine. Five. Construction machinery bearings used in engineering machinery in rolling bearings include deep groove ball bearings, tapered roller bearing and other large ball bearings, according to the application environment and operational conditions can be divided into two broad categories. Six. Mining machinery using bearing 1, most of the mining machinery used in outdoor, its working environment is very poor, installation, use and maintenance of bearing bring many adverse factors. 2, because are stone, dust much more special, if the seal failure, dust into the bearing inner exacerbate bearing wear. 3, mine machinery bearings mainly bear radial load. Seven. Agricultural machinery bearings are mainly used for supporting shaft bearings and shaft parts, and keep the axis of rotation accuracy and reduce the friction and wear between shaft and bearing, has been widely used in agricultural machinery. Due to agricultural machinery is often in overloading, vibration, impact work under the bad environment, thus bearing the rational use and maintenance of it is very important. And sliding bearing is a bearing capacity big, reliable operation, impact resistance, vibration absorbing, can cutting grading advantages, very suitable for application in high speed overloading, had a huge impact and vibration of agricultural machinery operation. Eight. Petroleum machinery bearing oil into oil drilling machinery, oil machinery, special car oil machinery, oil refining, industrial pumps, etc. Petroleum machinery bearing cover the mud pump oil equipment, faucets, derrick, crown, turntable, hook, such as the parts, the variety, size, structure difference is bigger, the quality stability of the supporting bearing, safe and reliable is very important. Nine. Excavator bearing excavator key parts bearing, mainly bear radial force, axial force, have some low speed, so generally choose larger double row circular cone roller bearings. Or use the cylindrical roller bearings with tapered roller bearings. Ten. With bearing metallurgical equipment, metallurgical equipment bearing is in ironmaking, steelmaking, roughing and finishing process of high temperature, high speed and low speed, water or under the condition of the use of foreign invasion, and other products. ZQM is suitable for steel mills all processes of long life, high reliability products, support the stability of metallurgical equipment operation. 11. Medical equipment bearing bearing as the key components of medical equipment, high-precision thin-walled cross roller bearing, in particular, our country has been developing for many years, has a mature technology conditions, high quality, high performance precision bearings, domestic can now gradually replace the imported similar cross roller bearing high prices. ZQM is the professional production of domestic medical equipment and high precision bearing, axial radial composite bearings and high-precision thin-walled cross roller bearing of the enterprise, the company has domestic advanced production technology and production technology mature, good quality control process, has now become the domestic medical equipment industry's leading manufacturers. Twelve. Papermaking machinery bearings today for the production of paper and cardboard paper machinery is very large, sometimes the length of 200 meters, paper machine net 10 meters wide, writing speed can reach 1800 m/min. Paper through a large number of roller, the stick is supported by rolling bearings. Extensive use of large aperture spherical roller bearings, bearing high reliability requirements; 13. Casting machine casting machine bearings under high temperature and water environment, is bearing a lot of grease lubrication, grease is added in a short period of time will be because of the high temperature melt the overflow, the maintenance is difficult, difficult on health and the equipment surface. In the steel structure bearing in the hot, humid environment corrosion rust easily, the failure rate is very high.
