Technical performance of joint bearings

Because the structure and working mechanism of the joint bearing is completely different from that of the rolling bearing, the joint bearing has its own technical characteristics and maintenance requirements.
Since the structure and working mechanism of the joint bearing are completely different from that of the rolling bearing, the joint bearing has its own technical characteristics and maintenance requirements.
(1) Working temperature
The allowable working temperature of the joint bearing is mainly determined by the matching materials between the sliding surfaces of the bearing, especially the plastic material sliding surface of the self-lubricating joint bearing, its load-carrying capacity at high temperatures

There will be a downward trend. For example, when the sliding surface material of a lubricated joint bearing is paired with steel/steel, its allowable operating temperature depends on the allowable operating temperature of the lubricant. But for all lubrication types and

In terms of self-lubricating joint bearings, they can be used within the temperature range of 30°C ~ +80°C and maintain the correct bearing capacity.

(2) Inclination
The inclination angle of the joint bearing is much larger than that of the general adjustable centering rolling bearing. It is very suitable for use in supporting parts with low concentricity requirements. The inclination angle of the joint bearing varies with the size and type of the bearing structure.

Type, sealing device and support form are different,-the inclination range of the general radial joint bearing is 3°~15°, the inclination range of the angular contact joint bearing is 2°~3°, the inclination of the thrust joint bearing

The angle range is 6°~ 9°.
(3) Cooperate
In any case, the selected fit of the joint bearing must not cause uneven deformation of the ferrule. The selection of the nature and grade of the fit must be based on the bearing type, supporting form and load.

The size and other working conditions are determined.
(4) Loading and unloading
The assembly and disassembly of joint bearings should follow the following principles, that is, the force applied by assembly and disassembly cannot be directly transmitted through the spherical sliding surface. In addition, auxiliary loading and unloading tools should be used, such as sleeves,

Disassemblers, etc., directly and evenly apply the externally applied loading and unloading force to the matched ferrule, or use auxiliary methods such as heating to perform unloaded loading and unloading.
