How to determine whether import IKO one-way bearing can repair to use

Bearing is available judgment, mainly considering the one-way bearing damage degree, mechanical properties, importance, and operating conditions, to the next overhaul period. If there are the following defects cannot be used again, IKO bearings must be replaced new imports. Inner ring and outer ring, rolling element and cage on any one have crack or gap. Ring, rolling body fracture on any one. Rolling on the pavement, guard, rolling body CARDS have a significant injury. Cage wear significant or rivet significant relaxation. Raceway surface rust, rolling body, injury. On the raceway surface, rolling body has serious indentation and playing. Inner ring diameter or outer diameter surface has obvious creep. Due to the hot color is obvious. The bearing grease sealed, sealing ring or dust cover breakage is obvious. Most of the bearing damage for many reasons - — Than previously estimated load, the effective sealing, tight fit is too small, as a result of import IKO bearing clearance, etc. Any of these factors factors there is its special damage forms and will leave a special signs of deterioration. Examine damaged shaft bearing, therefore, in most cases can find its possible causes, generally speaking, a third of the one-way bearing damage resulting from the fatigue damage, a third of the other resulting from poor lubrication, a third of the other resulting from pollutants into the bearing improper handling or installation. However, the damage pattern is also related to industrial category. Pulp and paper industry, for example, mostly due to bad lubrication bearing damage or contamination is not due to material fatigue. Bearing state of burn injury refers to: the bearing raceway wheel, roller and cage in the rotation sharply fever until discoloration, softening, deposition and damaged. The second is probably too big load ( Preloading is too big) 。 Speed is too large. Clearance is too small. With water or other foreign matter invasion. If the above two cases are not the shaft, the accuracy of bearing box, shaft deflection. See here, I think everyone wants to know the solution, first of all, to study lubricants and lubrication method, choose to import IKO bearing lubricant, and its dosage, and the selection of the bearing must be corrected. Study to cooperate, bearing clearance, and preloading, and improve the sealing device. Check the shaft and the precision of the bearing housing. Of course, if you have any experts beside you, let him follow you learn best operation! 1, bearing maintenance: for as long as possible in good condition to maintain the performance of the bearing was required to 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. Points for maintenance operation, with the rotation of the one-way bearing the sound, vibration, temperature, the state of the lubricants and so on. 2, bearing maintenance: bearing cleaning: removing bearing under repair, the appearance of the first record 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 to spin bearing with dirt, can damage the bearing rolling surface, should be pay attention to. In coarse clean oil, use a brush to remove grease, adhesive, after clean, roughly into fine cleaning). Fine cleaning, is to import IKO bearing side rotation in the wash oil, while carefully cleaned. In addition, the clean oil is always kept clean. 3, bearing inspection and judgment: in order to judge whether the bearing of the removed, can use to import IKO bearing in clean water after inspection. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the one-way 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.
