Damage condition: When the bearing receives the load rotation; the raceway surface or the rolling surface of the inner ring and the outer ring have a fish scale-like peeling appearance due to the rolling fatigue. Cause: The load is too large. The equipment is poor (non-linear) torque load foreign matter intrusion Influent water, poor smoothness, smoothing agent is not suitable for bearing clearance is not proper. Bearing box accuracy is not good; bearing housing rigidity unevenness axis deflection is large rust, corrosion point, scratch and indentation (outer deformation appearance) Development.
Method: Check the size of the load and the bearing improvement equipment used in the study again to improve the sealing equipment, stop the rust prevention. Use the smooth viscosity of the appropriate viscosity, improve the smooth method. View the accuracy of the shaft and bearing box. View the clearance.
According to the professional professor, according to the direction and nature of the load acting on the FAG bearing and which one of the inner and outer rings is rotated, the load received by each ferrule can be divided into rotating load, stop load or non-directional load. Accepting the rotating load and not directional The ferrule of the load should be static cooperation (interference cooperation); the ferrule that stops the load; the transition cooperation or the cooperation (play cooperation).
FAG imported bearing load is large or accepts oscillation and impact load; its interference must be increased. When hollow shaft, thin-wall bearing box or light alloy, plastic bearing box is used; the interference must also be increased.
When the demand insists on high rotation; high-precision bearings must be selected; and the dimensional accuracy of the shaft and bearing housing should be improved; the over-interference should be prevented; if the interference is too large; the shape accuracy of the shaft or bearing housing may affect the bearing ring. Shape; then jeopardize the rotation accuracy of the bearing.
Non-separable bearings (such as deep groove ball bearings) inner and outer rings are selected for static cooperation; FAG imported bearing equipment, disassembly is extremely inconvenient; it is best to choose one of the inner and outer rings to cooperate.
