The fatigue life of roller bearing lubrication and friction

Bearing fault characteristic late to exhibit serious failure (generally axle Backing bearings damage such as burns, sand shelf spallation, raceway, beads and wear) is not more than one week big time, equipment, greater capacity, faster speed, and its The shorter the interval. Therefore, the actual thrust spherical roller bearing fault diagnosis, once found fault with advanced features, should decisively determine the bearing is faulty, repair as soon as possible.
The fatigue life of roller bearing lubrication and friction, wear, temperature, vibration, etc. have a major impact, there is no normal lubrication, bearings will not work. Cause bearing damage analysis showed that about 40% of the bearing damage are related with poor lubrication. Therefore, the bearing well lubricated bearing is to reduce friction and wear of effective measures.

Bearing market demand

Thus ensuring the wheel backing bearings themselves in every direction can rotate back and forth, as we reduce the effort and time to repair. With the continuous improvement of the quality of the plastic beads, plastic beads, high sealing, low noise, long-life performance more effectively guaranteed,special bearing and because plastic beads materials, production equipment, improved reliability of plastic beads practical and effective guaranteed level of quality has reached the international advanced level, in a variety of high-reliability requirements can be reliably achieved using the occasion to meet the market demand for high-end wheel bearings goal.

Bearing identification method

Many imported Backing bearings how do we go tell? To tell you about:
The packaging is clear: Under normal circumstances, are factory brand has its own dedicated designer of external packaging design, production conditions and arrangements for making the production of the factory clearance, so in terms of packaging lines to color is very clear and unambiguous . (Some imported brands of accessories package also devoted to the protection of their intellectual property unique design, the content of which in the future will continue to carry out a detailed description).

NSK lysn-bearing sales center in Hefei

According to the introduction NSK paired tapered roller bearing distributor in China , Hefei NSK bearing production company with total investment of 2 billion yuan , from contract to the foundation in just four months.NSK lysn-bearing sales center in Hefei , Oct. 20 hearing - Seiko (NSK LTD.) To invest in China 's first 12 production bases , but also NSK invested in Mainland China 's largest production base in Hefei, NSK bearing production company , in October 2011 20 in Hefei high-tech Zone groundbreaking ceremony was held .

     

Chief Financial backing bearings Officer Edward

The world's largest construction machinery giant Caterpillar Group President and Chief Financial backing bearings Officer Edward Leip said recently in Shanghai , the largest in the history of Caterpillar to participate in Shanghai BMW Exhibition , highlighting its commitment to long-term development in China and the Chinese market confidence.
China International Construction Machinery , Building Material Machines , Construction Vehicles and Equipment Expo , namely Shanghai BMW Exhibition (baumaChina) began in 2002 , held once every two years , is designed to help exhibitors develop business in China and Asia markets . According to reports, Caterpillar in the exposition area of ​​over 12,000 square meters exhibition hall , displaying nearly 50 machines Cylindrical roller bearing are widely used in the Chinese market , a variety of services and technologies.

The use of tapered roller bearings

2010, Wafangdian Bearing city cylindrical roller bearing as the carrier with the new planning 150 square kilometers of coastal economic zone as a platform four, has held the 14 games will be the theme of investment Tapered roller bearings in the local and Shenzhen, Wenzhou, Ningbo and other cities: total contract 74 projects, totaling 87.3 billion yuan, of which yuan more than the large projects reached 60. The introduction of a large number of high-end project will help to build new industrial Wafangdian city, ZWZ invest in the construction of the foundation bearing the city center project to improve the bearing of all influence. Sinovel Heavy large tapered bearing propeller and ductile Backing bearings iron castings expansion project.

cylindrical roller bearing

cylindrical roller bearing is a kind of taper bearings machinery and equipment vital components. Its main function is to support the mechanical rotating body to reduce the equipment in the transmission process, mechanical load coefficient of friction. Backing bearings is an important foundation for all types of machinery and equipment, spare parts, its precision, performance, longevity and reliability of the host precision, performance, longevity and reliability play a decisive role. Mechanical products,crossed taper bearings are precision products requires not only a comprehensive support mathematics.

joint roller bearing basic technology research and academic exchanges

Henan SKF backing bearing sales center there is news that today one of the world's largest bearing company - SKF Group , recently sent a delegation to visit again , Henan University of Technology ( HKUST referred River ), SKF delegation and the river HKUST the leadership of Mechanical Engineering on personnel training, joint roller bearing basic technology research and academic exchanges , and business products and technology demonstrations and other issues were widely discussed and reached consensus on a number of intentions and . We follow Henan SKF bearings distributor SKF Group sales center to find access to Henan University of Technology on behalf of the whole process .

In the current domestic market

In the current domestic market, high value-added precision bearing demand and large compound growth rate of around 20% , although the growth speed, great market potential, but at present the vast majority of our production is small-scale and small and medium tapered bearing bearings bearing the above in large-scale production accounted for less than 3%.
Bearing components are fixed and reduce the coefficient of friction in the mechanical load transmission process. In recent years, China's bearing market is expanding , however , China's stainless steel slewing bearing  industry is still big but not strong , the data show that in 2012 China's bearing industry sales reached 142 billion yuan , mainly in the production of low-end bearings, and high-end bearings are mainly rely on imports . This also led our country there is a big gap from the major industrial countries .

The reason of imports bearing failure is often multifactorial

The reason of imports bearing failure is often multifactorial, affecting all design and manufacturing process factors will fail with four-row cylindrical roller split roller bearing on , analyze it difficult to judge. In general , and in general can be analyzed from the viewpoint of both the factors and the use of intrinsic factor. Using adjustment factors mainly refers to the installation , use and maintenance , repair and other maintenance meets the technical requirements. Installation conditions is one of the primary factors in the use of factors ,four-row cylindrical roller cylindrical roller bearing are often caused by improper installation package bearing the stress state changes between the various parts , bearing in abnormal state operation and early failure. According bearing installation , use, maintenance, maintenance of technical requirements for the operation of the bearings to withstand load, speed , temperature , vibration, noise and lubrication condition monitoring and inspection , abnormal immediately find reasons to adjust to normal.
