The classified method of joint bearing
1 joint bearing can bear load according to its direction or nominal contact Angle different, divided into the following kinds of.
1.1 - used to bear radial load to the heart joint bearing, the nominal contact Angle from 0 degrees to 45 degrees, according to its nominal contact Angle is different, can divide again:
A. the radial contact to the heart joint bearing - nominal contact Angle of 0 degree to the heart joint bearing, suitable for bear radial load.But also can bear radial load at the same time, the little bear axial load.
B. angular contact centripetal knuckle bearing - nominal contact Angle is greater than 0 degrees, but less than or equal to 45 degrees to the heart joint bearings, can bear radial load and axial load and the role of joint load.
1.2 thrust bearing joints - used to bear axial load, the nominal contact Angle is greater than 45 degrees to 90 degrees, according to its nominal contact Angle is different, can divide again:
A. the axial thrust bearing joints - nominal contact Angle of 90 degrees of thrust bearing joints, suitable for pure under axial load.
B. angular contact thrust bearing joints - nominal contact Angle is greater than 45 degrees, but less than 90 degrees of thrust bearing joints, suitable for bear axial load, but also can withstand the combined load (when the radial load value shall not be greater than 0.5 times that of the axial load).
1.3 joint bearing according to its outer ring structure is divided into:
A. the overall bearing outer ring joint;
B. double half bearing outer ring joint;
C. single slit bearing outer ring joint;
D. double slit outer ring (cutting points circle) joint bearing.
1.4 joints, rod end bearing according to whether attached or installed on the rod end can be divided into:
A. general joint bearing;
B. rod end joint bearing.
1.5 joint bearing should be added according to the work whether lubricant can be divided into:
A. the self-lubricating joint bearing;
B. self-lubrication of joint bearing.
1.6 joint bearing can bear load according to its direction, nominal contact Angle and structure is divided into:
A. the centripetal knuckle bearing;
B. angular contact bearing joints;
C. thrust bearing joints;
D. rod end joint bearing.
Joint bearing is what?
Joint bearing is dominated by a spherical outside within the inner ring and a spherical outer ring, can bear larger load.According to the different types and structure, can bear radial load, axial load or the joint of the radial, axial load.Because the inside is outside the sphere with composite material, so the bearing can produce self-lubrication at work.Commonly used for low speed swinging motion, also can be tilted movement within a certain Angle, when the hole and shaft bearing shell not concentricity is larger, can still work normally.Self lubricating joints and auxiliary promise used in water conservancy, professional machinery and other industries.
Joint bearing is widely used in engineering hydraulic oil cylinder, forging machine tools, engineering machinery, automation equipment, automobile shock absorber, hydraulic machinery and other industries. Introduction of joint bearing and classification of joint bearing is a spherical plain bearing, basic is by a spherical sliding sphere of inner and outer contact surface.According to its structure and type of different, can bear radial load and axial load, or combined load of radial, axial and effect.Because of joint bearing spherical sliding contact area is large, slope Angle is large, but also because most joint bearing adopted special processing methods, such as surface phosphating, zinc plating, chrome plating, or outside sliding surface lining, padded, spraying, etc.Therefore have bigger load capacity and impact resistance, and corrosion resistance, wear resistance, the heart, good lubrication and self-lubricating no lubrication characteristics of sewage pollution also can work normally even install dislocation.As a result, the motion of the joint bearing is widely used in low speed movement, tilted movement and rotation motion.
Imported bearing joints, such as SB, CF, GE, etc., there are a certain number and type of other types of centripetal bearing joints, rod end joint bearing, etc.
