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.Joint bearing compositionThe joint bearing is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface.
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. Self lubricating joint support is applied to water conservancy, professional machinery and other industriesThe application 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..
The joint bearing is a kind of sliding bearing with special structure. It has a simple structure than rolling bearing, which is mainly composed of a spherical inner ring and an outer ring of the inner sphere, can bear larger load, according to the different types and structures, can be combined load bearing radial load, axial load, radial or axial exist at the same time. Joint bearing generally used for swinging movement of the lower velocity (i.e., angular) because the sliding surface is spherical shape, can also be used as a tilt movement in a certain range of angles (i.e. aligning movement), the support shaft and the shaft casing hole concentricity is larger, can still work normally.The characteristics of joint bearings, joint bearings can withstand greater 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.
