SKF bidirectional thrust ball bearing of check project operation and damage the cause of the problem

Bidirectional thrust ball bearing of check project operation and damage the cause of the problem of two-way thrust ball bearings damage after removing check, according to the damage of bearing bearing failure and damage reasons. 1. Metal raceway surface spalling SKF bearing roller and the inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of contact stress. When stress cycles after reaching a certain value, the rolling element bearings, their work within or surface produce fatigue spalling. If the bearing load is too big, can make the fatigue. In addition, the bearing installation is not straight, shaft bending, also can produce roll flaking off. Bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise in the organization. 2. 。 Bearing burn burn SKF bearing the heat tint of raceway and rolling body. Burns is usually the cause of insufficient lubrication, lubricating oil quality does not conform to the requirements or metamorphism, and bearing assembly too tight. 3. Plastic deformation of SKF bearing raceway and roller contact surface appear uneven pits, bearing produce plastic deformation. The reason is bearing under static load or shock loading, local stress exceeds the yield limit of material on the surface of the work, this kind of situation usually happened in the low-speed rotation of the bearing. 4. Bearing race crack cause crack of the bearing race may be bearing fit tight, loose SKF bearing outer or inner ring, bearing deformation, inclusive of installation of bearing surface processing etc. 5. Cage fracture reason is the insufficient lubrication, rolling body breakage and seat skew, etc. 6. Retainers metal adhesion on the rolling body possible reason is that roller was stuck in a cage or insufficient lubrication. 7. Seat ring raceway serious wear and tear may be fall into the object in seat, lack of lubricating oil or lubricant brand is not appropriate. The main factors influencing the bidirectional thrust ball bearing damage is: load situation, lubrication, assembling, environmental conditions and material or manufacturing precision, etc.
