spherical plain bearing

Joint bearing is a spherical plain bearing, sliding contact surface is a spherical inner and an outer sphere, the movement can be rotated at any angle swing, which uses surface phosphide, fried mouth, insert a variety of special treatment pad, such as spraying The method is made. Spherical plain bearings with large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, lubrication is good.

Feature
Joint bearing can withstand a greater load. According to their different types and structures to withstand radial load, axial load or radial, axial joint load. Since the inner surface of the outer sphere inlaid with composite materials, so the bearing can be generated in the work of self-lubricating. Generally used for lower-speed swing motion, and low-speed rotation, but also for a certain tilt angle range of motion when supporting shaft and housing bore axis misalignment is large, still work. Self-lubricating bearings used in water conservancy, specialized machinery and other industries.
application

Self-lubricating bearings
Joint bearings are widely used in hydraulic engineering, metal forming machine tools, engineering machinery, automation equipment, automobile shock absorber, water conservancy machinery and other industries. Joint bearing is spherical plain bearing, the basic type is within the spherical sliding spherical contact surface of the outer ring. Depending on the structure and type, can bear radial load, axial load or radial, axial joint load.
Because spherical plain bearings sliding contact area is large, the tilt angle is large, but also because most of the articular bearing to a special treatment process, such as surface phosphate, zinc, chrome or outside the sliding surface lining, insert pads, such as spraying, Therefore, greater load capacity and impact resistance, and has anti-corrosion, wear resistance, self-aligning, self-lubricating lubrication or no lubrication good dirt pollution characteristics, even if the dislocation can be installed to work properly. Therefore, joint bearings are widely used for lower-speed swing motion, tilt and rotational movement.

Mechanical properties calculation methods in joint bearing

Spherical contact surfaces bearing joint (spherical plain bearing) has two "fit", which is called the contact coordinate contacts. Spherical Plain Bearings mechanical properties calculation methods in structural design plain bearings and wear analysis plays an important role. Coordination calculated surface contact pressure is a very complex issue, due to the limited existing Hertz model elastic half space, can not be used to calculate the spherical coordinate the contact pressure distribution. There are already a spherical contact unification model, namely Fang model, can solve the deformation problem of small spherical contact pressure distribution, the model for non-contact and coordination coordination contacting apply. But the contact area is not a complete spherical plain bearings, calculate the contact pressure distribution calculated on the basis of the need for further coordination sphere complete the contact model. In addition, the use of joint bearing will also appear free boundary effects, the joints bearing applications will have an impact. Free boundary effect produces contact pressure in the joints bearing outer edge focus and a large pressure gradient.
