1, stripping of FAG angular contact bearing
Damage status: when the FAG bearing rotates under load again, the raceway surface of the inner ring and outer ring or the rolling surface of the outer ring will be peeled off like fish scales due to rolling fatigue.
Reason: excessive load. Poor installation (non-linear) torque load foreign body invasion, water. Poor lubrication, improper lubricant FAG bearing clearance is not appropriate. FAG bearing box precision is not good, FAG bearing box rigid uneven shaft deflection large rust, erosion point, abrasion and indentation (surface deformation phenomenon) caused by the development.
Measures: check the size of the load and re-study the FAG bearing improvement installation method to improve the sealing device, stop rust. Use lubricants with appropriate viscosity to improve lubrication methods. Check the accuracy of shaft and FAG bearing box. Check the clearance.
2, Peeling of FAG angular contact bearing
Damage status: it presents a dark surface with slight wear and tear. From the surface to the dark surface, there are several tiny cracks as deep as 5-10m deep, and tiny shedding (micro-stripping) occurs in a large range.
Reason: the lubricant is not suitable. The foreign body got into the lubricant. Poor lubricant results in rough surface. Poor surface finish of paired rolling parts.
Measures: select lubricant to improve sealing device to improve the surface finish of paired rolling parts.
3. Card injury of FAG angular contact bearing
Damage status: the so-called stuck injury is the surface damage caused by the collection of minor burns on the part of the sliding surface injury. Linear scars on the circular direction of the slide surface and rolling surface. Roller end face of the pendulum line scar near the roller end face of the shaft ring surface clamping injury.
Reason: too much load, too much preloading. Poor lubrication. The foreign body bit in. Inclination of inner ring and outer ring, deflection of shaft. Poor accuracy of shaft and FAG bearing box.
Measure: check the load size. Prepress properly. Improve lubricants and lubrication methods. Check the accuracy of shaft and FAG bearing box.
4. The fracture of FAG angular contact bearing
Damage status: the so-called fracture refers to a small part of the fracture due to the roller rim or roller Angle of the local part of the impact of music or excessive load and a small part of the fracture.
