The Performance Of Joint Bearing

What is joint bearing
Joint bearing is a kind of spherical plain bearing, its sliding contact surface is an inner sphere and an outer sphere, which can rotate and swing at any Angle when moving. It is made of surface phosphating, blasting, inserts, spraying and other special processing methods.Joint bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication and so on.
Characteristics of joint bearing
Joint bearings can bear large loads.Depending on its type and structure, it can bear radial load, axial load or a combination of radial and axial loads.Because the outer sphere of the inner ring is inlaid with composite material, the bearing can produce self-lubrication in operation.Generally used for low speed swing movement, and low speed rotation, can also be in a certain Angle range for inclined movement, when the supporting shaft and shaft shell hole is not concentricity is large, it can still work normally.Self-lubricating joint bearings are used in water conservancy, professional machinery and other industries.

The performance of joint bearings
Because the structure form and working mechanism of joint bearings are completely different from rolling bearings, joint bearings have their own technical characteristics and maintenance requirements.
1.Working temperature
The allowable working temperature of joint bearings is mainly determined by the material matching between the sliding surface of the bearing, especially the sliding surface of the plastic material of self-lubricating joint bearings. Its carrying capacity will decline at high temperature.
2.Dip Angle
The Angle of joint bearing is much larger than that of general adjustable rolling bearing, which is very suitable for the use of supporting parts with low concentricity requirements. The Angle of joint bearing varies with the size of bearing structure, type, sealing device and form of support.
3.Cooperate
In any case, the matching selected by the plain bearing shall not cause uneven deformation of the ring, and the choice of the matching property and grade must be determined according to the working conditions such as bearing type, supporting form and load size.
4.Loading and unloading
The loading and unloading of plain bearings should follow the following principle, that is, the force exerted by assembly and disassembly cannot be transferred directly through the spherical sliding surface.In addition, auxiliary loading and unloading tools, such as sleeves and dismounters, should be used to directly and evenly apply the loading and unloading force imposed by the outside world to the matched rings, or use auxiliary methods such as heating for loadless loading and unloading.
5.The installation
When assembling joint bearing series, it is necessary to pay special attention to the position of the outer ring dividing surface.In order to avoid the load acting directly on the segmentation surface, the segmentation surface should be maintained at right angles to the coincidence direction.
6.Iubrication
When the load is applied and the speed generated by the swing movement is very small, the oil feeding type plain bearing can be operated without lubrication.However, it is generally necessary to supplement fats regularly.In the initial installation operation, it is recommended that the lubrication period be moderately shortened.No oil feed type plain bearings can be used in the case of no lubrication.However, if lithium soap-based grease is added before operation, the service life of joint bearings can be extended more.If grease is injected into the space around the bearing, the joint bearing will be more effective in preventing the invasion of dust and foreign bodies.
