MOS bearing breakdown maintenance

When the MOS bearing problems, the first idea should be check the maintenance, and not to replace. Today, we will put the world's top MOS bearing is introduced the commonly used maintenance types. Types of MOS bearing maintenance usually has the following three kinds: 1. MOS bearing breakdown maintenance: in MOS bearing failure occurs, inspection and maintenance downtime. 2. MOS bearing maintenance regularly, in order to guarantee the normal work of the host, according to the requirements of the host and the design of MOS bearing theory and experience, set up a maintenance cycle and preventive maintenance. 3. MOS bearing warning maintenance: use advanced MOS bearing fault diagnosis technology, the use of MOS bearing state real-time monitoring, forecasting is put forward, in front of the MOS bearing failure for repair. MOS bearing in the process of operation, there must be sound, such as temperature and vibration phenomenon. Therefore, for the MOS bearing in operation maintenance, can hear, touch, and MOS bearing fault diagnosis instrument method is used to find abnormal changes of MOS bearing according to the change of state to determine whether the MOS bearing are in normal working condition. Rolling bearings to remove check, according to the damage of MOS bearing judging MOS bearing failure and damage reasons. 1. Metal flake MOS rolling element bearing raceway surface and inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of the contact stress. When stress cycles after reaching a certain value, the rolling element bearings, their work within or surface produce fatigue spalling. If the MOS bearing load is too big, can make the fatigue. In addition, NSK bearings installed is not straight, shaft bending, also can produce roll flaking off. NSK bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise in the organization. 2. MOS bearing burn burn MOS 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 MOS bearing assembly too tight. 3. Plastic deformation of MOS bearing raceway and roller contact surface appear uneven pits, MOS bearing produce plastic deformation. The reason for this is that MOS bearing in large 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 MOS bearing. 4. MOS MOS bearing race bearing race crack causes of the crack can be MOS bearing fit tight, MOS bearing foreign or inner ring is loose, inclusive of MOS bearing deformation, installation of MOS 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.
