Single Row Ball Slewing Bearing Industry Domestic Market Structure
Aug 08, 2017

Single Row Ball Slewing Bearing industry domestic market structure
At present, the basic competition pattern of the domestic market is: the two types of enterprises are in the competitive advantage. First, it is a joint venture with well-known foreign enterprises, cooperation enterprises and wholly foreign-owned enterprises, its product technology and production equipment is more advanced, competition Strong force, mainly for foreign or foreign enterprises supporting the host, in the single row of ball bearings supporting the new industry applications occupy a certain advantage; Second, in the country engaged in production and operation time is longer, with a certain scale of domestic enterprises, production capacity Increase faster, higher brand credibility, the advantages of competition in the more obvious, and began to get involved in single-ball ball bearing industry, new applications.
       In order to expand the share in the high-end market, China's capital, technical strength is relatively strong single-pole ball bearing enterprises are constantly increasing investment in R & D, such as the development of industry standards than the more stringent internal standards to ensure that single Rotary bearings to further improve the geometric accuracy; increase the depth of hardened layer to improve the life of single-ball rotary bearing; to strengthen the research and development of anti-corrosion materials to promote the application of single-ball rotary bearings applications; the development of a number of test equipment, the use of computers Simulation simulation technology for Single Row Ball Slewing Bearing bearing capacity of the effective verification of the product structure size to optimize the design; At the same time these companies have begun to pay attention to Single Row Ball Slewing Bearing basic technology and related technology research and application.
         At present, China's single ball slewing bearing products mainly for the construction machinery industry supporting, in the field of wind power and other new applications show rapid development momentum. From the operating conditions of China's construction machinery industry over the years, the characteristics of cyclical fluctuations are more obvious, thus affecting the Single Row Ball Slewing Bearing market supply and demand situation. At present, the market for Single Row Ball Slewing Bearing a substantial increase in demand, Single Row Ball Slewing Bearing industry is developing rapidly.
How do I install a single row of ball slewing bearings correctly?
First open the Single Row Ball Slewing Bearing packaging, check the certificate and signs, to confirm the use of Single Row Ball Slewing Bearing model is correct.
A, installation plane
Installation surface should be clean, to remove all the excess material such as paint residue, beads, burrs and so on. Care should be taken not to allow the solvent to penetrate the inside of the Single Row Ball Slewing Bearing. Do not use solvents that damage the sealing material. Before installation, the mounting surface should be dry and free of lubricant. Measures should be taken to protect workers and the environment.
Install the bearing surface roughness is not greater than Ra = 12.5,6.3μm, the installation plane of the flatness of the error to be detected circumferential error and radial error. The circumferential level tolerance value corresponds to the standard value range with the diameter of the single row ball slewing ring raceway diameter.
In order to avoid the unevenness of the installation plane or bearing deformation caused by Single Row Ball Slewing Bearing partial overload, circumferential flatness error in any 180 degree range can only be a wave of ups and downs, and change gently.
B, the stiffness of the bearing
Standard Single Row Ball Slewing Bearing with zero clearance Single Row Ball Slewing Bearing has different requirements on the rigidity of the bearing.
C, positioning
Single Row Ball Slewing Bearing inner and outer ring raceway has a soft band, should be placed on both sides of the main load plane. That is, with the main load area staggered 90 degrees. There is a plug in the soft band or hit the "S" mark.
Also check the single row of ball bearings and mounting surface of the anastomosis, usually using the feeler check, if the anastomosis is not good, use the appropriate material to fill. Single Row Ball Slewing Bearings are prohibited from welding on the stand after installation.
Single Row Ball Slewing Bearings are all important parts of the force between the two parts that need to be rotated relative to both the axial load, the overturning moment and the radial load. With the rapid development of the host industry, Single Row Ball Slewing Bearings have been widely used. How to effectively improve the carrying capacity of Single Row Ball Slewing Bearings, has become the most concerned about the manufacturers of the problem, but also many scholars have studied hot issues. In order to improve the carrying capacity of Single Row Ball Slewing Bearings, to meet the market demand, single ball ball slewing bearing Co., Ltd. successfully developed a single row of single row ball single ball ball slewing bearing products, and in March 30, 2006 applied for a national invention patent The The main features of the Single Row Ball Slewing Bearing is a single row of single row ball slewing ring type to oval, the rest of the parameters and circular raceway Single Row Ball Slewing Bearing the same. The long half-axis and short-axis parameters of the elliptical raceway can be calculated according to the radius of curvature of the ball and the radius of curvature and contact angle of the contact point of the raceway and the ball.
