promote the formation of the wind power Bearing Test Machine industry development and industry chain

To shorten the gap between the world powers bearings , bearing manufacturing to improve our manufacturing level , the Chinese government has issued a series of industrial policies to support and encourage domestic enterprises towards the end bearing bearing localization direction. "Long-term Science and Technology Development Plan (2006 - 2020 ) " should be made to focus on the development of major equipment required for the design of key basic parts and components , manufacturing and key technologies Precision bearing for mass production . China's " bearing industry," second five "development plan" put forward , "Twelve Five" period, the bearing industry 's main business grew 11.84 percent average annual production average annual growth of 13.30% , industry profits grew 13.90 percent average annual total goals. This reflects the country fully affirmed the important status and role of the clutch bearings  ndustry in the national economy , as well as support for the development of industrial bearings , bearings for the healthy development of the industry provides a good opportunity for development .
According to Mr. Li Shuming Northwest bearing , general manager of introduction, Northwest Bearing developed "2.5MW wind power generation equipment spindle bearings " project, designed to meet the requirements of the user MWT-2500A (2.5MW) direct drive wind turbines. Can not only improve the company's own income , but also effectively promote the local wind power equipment, downstream industrial agglomeration and development in Ningxia , and promote the formation of the wind power industry development and industry chain   has far-reaching implications for Ningxia industrial restructuring, transformation of economic growth mode ; company developed the " heavy-duty vehicle nose cone bearing " project, in addition to improving the company's revenue , but also by dump truck with a nose cone bearing development, open -highway heavy-duty dump truck bearings supporting the localization market

Precision Bearing Industry believes that a complete research system

Bearing accelerate product development and process innovation, effectively supporting the oil and gas industry to promote the successful development series bearings , bearing subway loading test, the product lightweight technology upgrading, development of motor bearings . Companies large special bearings advanced manufacturing technology wind turbine bearings Joint National Engineering Laboratory where the relevant departments have been approved , will further enhance the company 's R & D capabilities . Meanwhile, the company won two secret military field qualifications, passed the state weaponry research and production licenses on-site Precision bearing assessment and weaponry GJB9001B-2009 quality management system certification second phase of the initial audit . 2013 Northwest bearing R & D expenditure amounted to 22,432,000 yuan , accounting for the company's net assets was 8.1% , accounting for the proportion of operating revenue was 6.9 %. Industry believes that a complete research system , active R & D investment , experimental methods , such as high levels of the company to provide a strong guarantee for the development of high-end bearings

stimulating demand for construction machinery

Since the implementation of the " two sessions" of economic growth targets proposed implementation of urban infrastructure construction projects around the climax off , started intensive railways, highways , subways, affordable housing , water , ports, airports and other major projects , prompting the construction machinery manufacturing recovery industry , stimulating demand for construction machinery , bearings market demand will subsequently released. From recent Gcr15 spindle steel downstream users in March production plan research situation , automobiles, marine vessels , oil pipeline industry to maintain stable operation ; engineering machinery, Precision bearing industry increased. Downstream industry demand for effective bearing steel increased compared with February . For example Gcr15 bearing steel companies in March contract orders generally good condition . Improved downstream demand is conducive Gcr15 bearing steel market stability , bearing steel prices steady rise is a major supporting force .

Bearing Manufacturing Industry Development of China's strong momentum of steady bearing steel market will bring positive effects to the good . A number of significant growth in roller bearings demand for high-end bearings , such as aerospace bearings, machine tool spindle speed precision bearings, ball bearing precision angular contact ball bearings , high-speed spindle bearings, precision bearings for machine tools photovoltaic industry , turntable bearings, wind power bearing , shield machine bearings, rolling mill bearings, high-speed rail bearings, automotive bearings, crane sheave bearings , turbocharger bearings, hydrodynamic bearings and so on.

double row and four row circular cone roller bearings

Tapered roller bearing mainly bear radial primarily diameter, the axial load. Bearing capacity depends on the Angle of the outer ring raceway, the greater the Angle, the greater the carrying capacity. The separated type bearing is a bearing, according to the wind turbine bearings  the number of columns of the scroll body can be divided into single row, double row and four row circular cone roller bearings. Single row tapered roller bearing clearance to users in the installation adjustment; Double row and four row circular cone roller bearings clearance has according to user requirements for a given when the products leave the factory, not the user.
Have a conical taper roller bearing inner ring and outer ring raceway, the tapered roller are arranged in between. All projection line on the surface of the cone axis high precision bearing  the same points together. This design make the taper roller bearing is especially suitable for composite (radial and axial load. Bearing axial load capacity is mostly determined by the contact Angle alpha; Alpha Angle is larger, the higher axial load capacity. Angle size by calculating coefficient of e; E value, the greater the contact Angle, the greater the bearing axial load of the greater applicability.

This load is Bearing Test Machine characterized by a relatively static radial load vectors and synthesis loop

Synthesis of radial load on the fixed load of the load from the local fixed ring raceway ring is exposed and sent to the appropriate local or bearing shaft . This load is characterized by a relatively static radial load vectors and synthesis loop . Bear the load ring , you can use a relatively relaxed. Synthetic <BR> rotational load of radial load applied to the full complement cylindrical roller along the circumferential Bearing manufacturer direction of the rotating bearing ring on the roller , turn the various parts , such as the rotation load , which is determined by the combined vector phase loop radial load rotation, bear . Work closely with the rotating load ring , in exceptional circumstances , load, if elected , is light or heavy loads , low speeds , and only occasionally rings , bearings hard materials and high slewing bearing surface roughness , rotating load bearing rings can also be used more loosely . Third load swing directional load or no load , the load ring radial direction of the uncertainties of the load, which is characterized by a ring raceway radial load vectors role of an impact load in a certain area , vibration, load , and its direction is the swing roller to bear a certain area , or acting on the bearing load , load values ​​change frequently . To bear the load swing , outer ring and weeks , bearings, holes should close conjunction. <BR> Used to adjust the full complement cylindrical roller bearings radial clearance as follows : <BR> 1, for cylindrical and oval-shaped bearing backlash
