The use of the fag bearing damage detection maintenance methods

Bearings are precision components, its use should be measured accordingly. No matter how high performance using fag bearing, if use undeserved, high performance will not be expected. So what is the bearing use method? When using bearing must pay attention to the following: 1, keep the bearing and the surrounding clean. Even the eyes can't see the little dust, will also bring bad influence to the bearing. So to keep the surrounding clean the dust from invading bearings. 2, carefully use fag bearing in use for bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. 3, use the appropriate tools to avoid operation with existing tools to replace, must use the appropriate tools. 4, to pay attention to the corrosion of the bearing bearing operation, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves. Rolling bearings to remove check, according to the damage of bearing bearing failure and damage reasons. 1. Metal flake bearing raceway surface rolling body 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, fag 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 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 fag 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 a fag bearing fit tight, loose foreign or bearing 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.
