The joint bearing is a special type of plain bearing. Its layout is simpler than that of the rolling bearing; it is mainly composed of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface; it can accept a large load; it is different according to it. Type and layout; capable of accepting radial loads, axial loads or combined loads of radial and axial forces. Joint bearings are usually used for lower speed rocking motions (ie angular motion); because the sliding surface is spherical; It can also perform skew movement (ie, aligning motion) within a certain range of viewpoints; when the support shaft is not the same as the shaft hole, it can still work normally. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The direction in which the joint bearing receives the load according to its accepted capacity. The nominal touch angle and layout method can be divided into radial joint bearings. Angular touch joint bearing. Thrust joint bearings and rod end joint bearings. The radial joint bearing (GE type) has a nominal touch angle of 0 degrees and is suitable for receiving radial loads and small axial loads. Angular touch joint bearing (GAC type) is divided into two types: angular contact radial joint bearing and angular touch thrust joint bearing. The angular touch radial joint bearing has a nominal touch angle greater than 0 degrees but less than or equal to 30 degrees, and is used to accept radial load. Combined load with axial load effect; angular touch thrust joint bearing with a nominal touch angle greater than 30 degrees and less than 90 degrees, suitable for receiving axial loads, can also accept combined loads, but at this moment its radial load must not be greater than axial load 0.5 times. The thrust joint bearing (GX) has a nominal touch angle of 90 degrees and is suitable for axial loads and cannot accept radial loads. Rod end joint bearings are adapted to accept axial loads with a small radial load (typically less than or equal to 0.2 times radial load).
