The relationship between the track of the bearing and the radial load

When the bearing rotates, the raceway surface of the inner ring and the outer ring of the bearing is in rolling contact with the rolling element, so the running track is a dark surface, and the running track attached to the raceway surface is not an abnormality, so that the load can be known. Conditions, so when disassembling the bearing, please pay close attention to and observe the running track of the raceway surface.

If you carefully observe the trajectory, you will know that you only bear radial loads, withstand large axial loads, withstand moment loads, or have extreme rigidity in the bearing housing. It is possible to check whether the bearing has been accidentally loaded and the installation error is too large, and it is a clue to investigate the bearing damage.

Introduction to the structure and performance of joint bearings

The joint bearing is a special type of plain bearing. Its structure is simpler than rolling bearings. It consists mainly of an inner ring with an outer spherical surface and an outer ring with an inner spherical surface. It can withstand large loads. According to its different types and structures, it can withstand radial loads and shafts. Combined load to load or radial and axial simultaneously. Generally used for low-speed oscillating motion (ie, angular motion), because the sliding surface is spherical, it can also be tilted in a certain range of angles (ie, aligning motion), and the difference between the support shaft and the shaft hole is different. When you are old, you can still work normally.
