Tapered roller bearings classification and uses

Tapered roller bearings axial load capacity depends on the contact angle, ie the angle of the outer ring raceway, the greater the angle, the greater the axial load capacity. Tapered roller bearings are up to the amount of single row tapered roller bearings. In the car's front wheels, and spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill and other heavy machines. Tapered roller bearings are separable bearings, inner and outer rings have tapered raceway. These bearings are loaded according to the Tapered bearing  of columns roller into single row, double row and four row tapered roller bearings, such as different structural types. Single row tapered roller bearings can support radial load and axial load in one direction. When the bearing radial load, will produce an axial component, so when you need another can tapered bearings  axial force in the opposite direction of the bearing to be balanced. Tapered roller bearings are mainly used to bear radial load mainly radial and axial joint load. Compared with angular contact ball bearings, bearing capacity, low speed limits. Tapered roller bearings can withstand axial load in one direction, a direction to limit the axial displacement of the shaft or housing. Double row tapered roller bearing outer (or inner) as a whole. Two inner (or outer) face similar small, middle spacer, clearance by adjusting the thickness of the spacer, and can also be used to adjust the thickness of the spacer double row tapered roller bearings preloaded.

Tapered roller bearings on the basis of components

According to the different nature of the friction of moving parts, the bearings can be divided into two types of rolling bearings and plain paired tapered bearing. China is one of the countries in the world earlier invention of rolling bearings, in ancient China, the structure has long been documented about the axle bearings. Seen from archaeological artifacts and data, China's oldest Rolling bearing structure with a modern prototype, appeared in BC Bearing is an important foundation for all types of Cylindrical roller bearing and equipment, spare parts, its precision, performance, longevity and reliability of the host precision, performance, longevity and reliability play a decisive role. Mechanical products, bearings are precision products requires not only a comprehensive support mathematics, theoretical physics and many other disciplines, but also materials science, heat treatment technology, precision machining and measurement technology, slim bearings technology and efficient numerical methods and powerful computer technology and many other disciplines to serve, so the bearing is also a representative of the national scientific and technological strength of the product.paired tapered bearing Is fixed and reduce part load coefficient of friction in mechanical transmission process. You can also say that when the other parts on the shaft relative motion to each other, the process used to reduce the power transmission coefficient of friction and keep the shaft center position fixed parts. Bearing is a kind of modern 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.

various fluorinated Tapered roller bearings aromatic liquid crystalline compound

 With the development of liquid crystal material and the rapid development of  devices, from biphenyl nitrile, esters, oxygen-containing heterocyclic benzene, pyrimidine ring type liquid crystal compounds have evolved to the ring base (linked) benzene, diphenyl acetylene class, ethyl bridge bond classes, and various fluorinated aromatic liquid crystalline compound, Japan recently synthesized structural stability of vinyl fluoride crystal Cylindrical roller bearing‍ compounds, the molecular structure more stable and continue to meet  performance requirements. Although Tapered roller bearings the amount of the world's  monitor market is growing, but our share of the  industry in which it is small, but is still concentrated in the  liquid crystal material, there are certain developments in  liquid crystal materials, but in the backing bearings‍ world  market the lack of competitiveness, a strong appeal to the state should take positive measures to strengthen the liquid crystal display devices Tapered roller bearings and materials research and development of human and capital investment, is displayed on the industry to the upstream inclined to rejuvenate the Chinese nation  industry in the flat

Tapered roller bearings Economic Zone grasp opportunities

an increase of 29.2%; industrial added value of 35.3 billion yuan, an increase of 28.8%, the bearing industry has become the first Wafangdian an industry. Wafangdian party secretary Xing-Wei Liu said the city is in accordance to build two industrial clusters and the idea of ​​the six industrial base, the introduction of nurturing top talent, improve the high-end research and development capabilities in an effort Crossed Tapered Roller Bearing to "bearing capital" Wafangdian, playing with a tip the development of a world-renowned city bearing capacity.
Area of ​​less than 3,800 square kilometers of but it is the birthplace of China's bearing industry, developed more than 500 years of  led by bearing production and ancillary businesses. Among them, the size of the business 258; sales revenue over $ 50 million enterprise 27 million over the business 9. 2009 achieved sales revenue of over 150 bearing billion. Bearing industry practitioners 5 million, accounting for 16.1% of total employees in the same industry, accounting for about 20% of the national Roller bearing total output value of the industry.
 stressed  coastal economic zone are to seize the development of open and Dalian global urbanization strategic opportunities, and vigorously promote coastal development, vigorously develop strategic emerging industries, to enhance urban functions, improve people's livelihood well-being, for the "second five "to achieve a new leap in scientific development and lay a solid foundation, built in the Sea region will  competitive emerging modern industrial city.
