Industrial INA maintain basic method of self-aligning ball bearings, bearings of knowledge

For as long as possible in good condition to maintain INA bearings have the performance of 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, have bearing the rotation of the sound, vibration, temperature, the state of the lubricants and so on. Cut heart ball bearings bearing clean: remove overhaul, 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 INA 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, 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 INA bearings. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the self-aligning ball 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. Separation of INA bearings and bearing, rolling body, the outer ring raceway surface can be respectively. Large bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of bearing high must check carefully. Grease on the bearing has a very important role in protection, in order to better play a role of grease lubrication of bearings, we need to follow the standards of six: first: the classification of the grease and choice; Mainly according to the temperature and the working conditions to distinguish: grease can be classified according to their allowable working temperature, lubrication grease consistency and ability is affected by temperature, operating under a certain temperature must choose a one-way bearing under the same temperature has the correct consistency and good lubrication effect of oils and fats. The second: rust resistance; Use within the INA bearing grease must have antirust effect, rust inhibitor is best can not dissolve in water. Grease should have good adhesion, and can form a layer of oil film on the surface of steel. Third: oil viscosity; If the wrong choice grease all preventive measures of self-aligning ball bearing is useless, choose a grease, its oil viscosity in working temperature is it is important to be able to provide adequate lubrication effect, viscosity is mainly affected by temperature, it with the temperature rising and falling, is that it increased when the temperature decreases. Fourth: mechanical stability; Grease in the mechanical processing will become soft, resulting in leakage. During normal operation, oil will by the bearing to the bearings. If the mechanical stability of the oil is insufficient, operation process, the structure of the soap grease causes mechanical disruption of oil was damage, and loss of lubrication. Fifth: can't mix oil; Never mix the fat off from the incompatible, if two incompatible oil mixture, usually will soften its consistency, might end up INA bearing damage caused by oil easy to loss. Sixth: oil seal is rigorous; Oil seal is necessary to protect and self-aligning ball bearing lubricant from external contamination of barrier, bearing in the process of operation, regardless of debris or moisture can penetrate bearings, in case the cause of its broken
