Characteristics and use of joint bearings
Features of joint bearings:
The joint bearing can bear heavy load. Depending on its type and structure, it can accommodate radial loads, axial loads, or simultaneous loads in both radial and axial directions. Because the outer sphere of the inner ring is provided with a composite material, the bearing can generate self lubrication at work. Generally used for low speed swing motion, and low speed rotation, but also in a certain angle range for tilting movement, when the support shaft and shaft shell hole concentricity is larger, still can work normally.
Application range of joint bearing
Joint bearing is widely used in engineering hydraulic cylinder, forging machine, engineering machinery, automation equipment, automobile shock absorber, hydraulic machinery and other industries. The introduction and classification of joint bearing joint bearing is spherical bearing, the basic type is composed of spherical with spherical sliding contact surface of the inner and outer rings. According to its structure and type, it can bear radial load, axial load, or combined load of radial and axial simultaneously. Because the spherical sliding contact area of joint bearing large tilt angle, but also because most of the process of joint bearing special processing method, such as surface phosphating, galvanized, chrome plated or sliding surface lining, padded, spraying etc.. Therefore, the utility model has the advantages of large load capacity and shock resistance, and has the characteristics of corrosion resistance, wear resistance, self aligning, good lubrication, self lubrication, no lubrication and dirt pollution, and can work even if the installation is misplaced. Therefore, the joint bearings are widely used in low speed swing movement, tilt movement and rotation movement.
