Industrial IKO eccentric bearing maintenance considerations - bearing knowledge as a whole

For as long as possible in good condition to maintain IKO bearing performance, maintenance, repair, in order to prevent accident arrangement to ensure the reliability of operation, improve the productivity and economy. To maintain the best conditions of mechanical operation of the corresponding operation standard, on a regular basis. Content includes monitor running status, supplement or replacement of lubricants, remove the check on a regular basis. As maintenance issues in the operation, the rotation of the eccentric bearing overall sound, vibration, temperature, the state of the lubricants and so on. Bearing clean: remove bearing repair, first record the appearance of the bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Tear open come down to the bearing cleaning, rough washing and fine washing, respectively in the container, put a metal mesh bottom first, make the bearing is not direct contact with dirt from the container. Coarse when cleaning, if rotating the IKO bearings with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use the brush to remove to, adhesive, after clean, roughly into fine cleaning). Fine cleaning, bearing side rotation in the cleaning of oil, while carefully cleaned. In addition, the clean oil is always kept clean. Bearing inspection and judgment: in order to judge whether the bearing of the removed can use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, an overall increase in eccentric bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. High temperature often said bearing is in abnormal situation. High temperature is also harmful to within IKO bearing lubricant. Sometimes bearing overheating can be attributed to outer spherical bearing lubricant. If the bearing in more than 125 degrees Celsius temperature operation for a long time, will reduce the bearing life. The causes of high temperature bearing include: insufficient lubrication or excessive lubrication, lubricants containing magazine, the load is too large, the eccentric bearing damage, clearance, and the oil seal of high temperature and friction and so on. 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, IKO 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. Burn the outer spherical 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. Bearing raceway and roller contact surface appear uneven pit, illustrates the eccentric bearing produce plastic deformation. The reason is IKO 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.
